I am trying to find ways of resetting my up coming inspection warning on my Polo (please stay with my. I know this is a Golf sub forum) There is little info on the Polo forums or replies but loads here... I did read on the Golf pages that service is dependant on the ID plate (stuck on the drivers side pillar on my polo) If a Golf had QG1 it meant is was long life service intervals.. My Polo has this same code ![]()  yet my service reminder comes up yearly.. does this mean the garage i bought it off (as used VW 18 months old) changed the interval to yearly and I can treat this differently.. i.e reset it as if yearly? Or as my title.. codes are not universal in this case? desperate to find good information... Thanks for looking |

grazuncle : Hi. So- this is a Polo AW 1.0 TSI (DSG maybe?). This means that the car has a 3Q0 chassis which is more akin to the mk7.5 Golf than the mk7 (which uses a 5Q0 chassis). OK - as to your specific questions: Yes, the PR codes in your picture ARE universal - meaning that the same codes appear both across models within a particular make and across makes in the VAG stable (so the same codes are used by VW and Audi) The PR code QC1 on the luggage label does indeed signify that this car has been factory built with what VW call "Service Interval Extension". For reasons that will become obvious later in my response - I'll use the acronym ESI rather than SIE for this facility.
Now - my apology, but I have to start this discussion by introducing a bunch of further acronyms (bear with me - it will pay dividends in your ultimate journey to understand this stuff).
For MQB platform cars generally and for 3Q0 chassis cars in particular, management of service interval maintenance is controlled by the module that OBD11 calls Dashboard (which lives @ address hex17 on the CAN network). This module has lots of adaptation channels devoted to what's known as the Service Reset Interval (SRI) facility. These channels are structured broadly into 3 x categories with starting acronyms in their titles as follows:
- FIX: as the name implies, this option uses the principle of setting the service interval based on the earlier of a preset time interval, or a preset distance traveled from the last service
- ESI: this option is based on a variable service interval that is calculated from the vehicle's actual conditions of use and from the driver's style of driving. Of course, to do this the car must be fitted with an enhanced set of transducers that measure the actual oil-wear - this data being necessary to feed the ESI calculation algorithm.
- SIA: I'm not entirely sure about this acronym, but my hunch is that the values in these channels are the numbers that are substituted into the Dashboard module registers when the driver uses the manual SRI procedure that is described in the user-manual - maybe? I would welcome comments if anyone here knows how these channels are used!!!
I suggest that you eyeball these adaptation channels (especially the current settings) in the hex17 modules in this car to acquaint yourself of the type of parameters that are needed to manage both ESI and FIX options
So, in respect of your specific question, the software switch that determines which service mode the hex17 module will use to manage SRI on this car is entirely set by the adaptation channel - ESI: oil quality. The setting for this software switch works like this: - If this channel is set to high oil quality, the Dashboard module use the bunch of ESI channel settings
- If this channel is set to poor oil quality, the car will use the bunch of FIX channel settings. Note: "poor" doesn't mean that the oil quality is sub-standard, it simply means that it's NOT the high oil quality setting
Of course it's absolute nonsense to set a car to use ESI if the requisite transducers are not fitted to the car because the ESI algoritm will make incorrect decisions - however, this appears NOT to be the case in this instance.
I have no idea why in this instance a car that clearly has the advantage of extended maintenance interval has been programmed as if it doesn't have this facility. If I was into conspiracy theories (and I'm not) - I might accuse the dealer of maximizing revenue - but I will leave this rationalization for your determination!! Nevertheless, if this was my car, I would welcome a explanation from the dealer as to why paying for the QC1 option in the purchase cost was ignored/changed? before delivery . Hint: if you pursue my suggestion, look-out for the dealer using the "Nuremberg-Defense"; it wasn't the dealer's fault - this was just the setting from the wholesaler! Of course your follow-up question is: if that's true - why wasn't the inconsistency picked-up in the dealer pre-delivery service (presumably there was a dealer pre-delivery service completed on this car before you handed-over the large purchase cheque)?

Wow! this is what you call an answer and good call.. yes an 2019 AW 1.0 TSi manual gearbox!
A lot of information for someone aspiring to newbie.. LOL
I don't know if this is significant but I have reset the yearly dashboard pop up via the multimedia screen and apparently can be done also via the reset buttons under the dashboard dials (rev and speed dials)
You all may be wondering why I'm asking at all if i can do that anyway.. good question. I was confused at the QG1 designation and a yearly prompt and want to know what is actually set (via OBDII) and where.. hence....
My next problem is how/where to look for the info on OBD app.. under Engine 01 module? (or a link?)
sorry to be a nuisance.. grateful

grazuncle : Thanks for the kind words! So, an "aspiring newbie" huh? Ain't nothing wrong with that - we were all "aspiring" new-bees at some time in our experience and I suspect we NEVER shed this particular trait regardless of our expertise (old adage: the more we learn, the more we understand what we don't know)! OK- my apology for not being more instructive in my first reply. Follow my 10 x step instructions below to access the SRI channels on your Polo (I assume that you are using the iOS version software): - On the Polo - ignition-ON, engine-OFF. Plug the OBD11 dongle into the car's OBD port (not sure where this is located on a Polo)
- Fire-up OBD11 software on your iPhone and connect to the dongle
- At the Home screen - select the highlighted bit shown below:
 - You should now be presented with the Control Unit screen
- This screen contains a list (in visual form) of ALL the control modules that have been factory built into the car.
- Notice that each module is separately shown and each has a colored number in the upper left corner. This is the "address" of the model which lives on a virtual platform called the "CAN network".
- Also, the number ain't decimal - which is why it might contain alphabetic digits like A, B....F. Instead of base 10 arithmetic, the numbering system that is used for module addresses is hexadecimal (it's a computer thing!)
- Scroll-down the list of modules until you see Dashboard - which should have the number 17 in the colored address box. Select this module
- You should now see the specific screen for Dashboard module.
- Scroll down until you see Adaptations - select this option
- You are presented with the adaptation channel database within the Dashboard module. The channel names enforce a strict 2 x part structure like this:
- Parent name - each channel can have only ONE parent name
- Child name - A parent name may have many child names
Note: The adaptation database screen contains a list of Parent names ONLY
- Enter terms like "FIX", "ESI", "SIA" into the search box at the top of the screen to access the SRI channels.
- Click on any channel parent name that is returned from the search term to access the child channels and view their values.
Don
PS: Another method for viewing the channel settings is to create a back-up of the Dashboard module. This procedure creates a file that contains a data-dump of the entire adaptation channel database in the module - see HERE

No apology needed....
I'm just grateful for any reply.. especially with such detail!
I'm on android but get the process... I'll definitely link this info, and any results I find, to the OBDII Polo MK6 forum.
grateful... dv52.

grazuncle : Wow - this "aspiring newbie" is a fast learner!!! Respect!! Given that you have created a backup of the Dashboard module and because this module has an adaptation channel count of somewhere near 250 (depending on the module Part-Number), it's far easier for us carbon based life units to read the information in a text form. To do this, we must first digitize the database in the Backup like this: - Fire-up Android version OBD11 software - you don't need to connect to the dongle/car
- On the opening screen, click-on the tab on the extreme upper left-side (it's the 3 x horizontal lines shown below)
- Select Garage
- If you have more than one vehicle registered to your account - select the car
- Select History
- You should see the 2nd screenshot in my picture below (which I created for another purpose)
- Click-on the button shown to "deselect unwanted information"
- From the list - deselect ALL entries except Backup (or Full Backup if you have created this type file). Press OK
- The 2nd screenshot below will now contain only Backup information
- Click-on the envelope symbol
- Select your preferred email App and send yourself a copy of the Backup information
After you receive the email from OBD11 - open the data file with a high-level application like MS word
Find the channel:ESI: oil quality - what is the setting? Don

Thanks for the encouraging words.. The carbon based unit is complying..  I'm getting as far as selecting the envelope.. It generates a log but does not offer a destination screen. I have an email in my settings (not my OBDII app login email if that makes any difference?) If I hold the envelope icon down for a second i get Share pop down but clicking it does nothing either.. There is some rookie mistake here.. LOL |

grazuncle Hmm............I wouldn't think that using a different email address to your OBD11 address would be a problem! I have absolutely no idea whether OBD11 software supports Android's Share facility. Maybe try temporarily disabling the Share function on which ever version tablet/mobile-phone you use (I don't know how this is done - maybe Mr Google can help). Again, I suspect (wild guess really) that the reason why a car with QC1 isn't using ESI is because the adaptation channel ESI: oil quality is set to poor quality. Maybe post-up a screenshot as you have done in your previous post?
As an example of the ESI adaptation channels that should be on this car - I've pulled the list below from the Dashboard module on a 3Q0 chassis vehicle that has QC1 and ESI active - from my MQB platform database.
Hopefully to make the list more understandable, I've ordered the channels into functional categories (or. at least my guess of the categories). The channel values in my list are simply those settings that were present in the module when I created the backup file.
ESI parameter threshold - user applied- ESI: maximum value km-driving distance/inspection > 30000 km
- ESI: minimum value km-driving distance/inspection > 15000 km
- ESI: maximum value of time between inspections > 730 d
- ESI: minimum value of time between inspections > 206 d
- ESI: soot entry > 10000 km
- ESI: thermal load > 4300 km
ESI algorithm - calculated values - ESI: distance driven from inspection > 6700 km
- ESI: time from inspection > 254 d
- ESI: Resetting ESI > no warning (this channel activates/disables the maintenance due message displayed on the dashboard)
ESI software switch - ON/OFF - ESI: oil quality > good oil quality
Comments: - Because the units for "soot entry" and "thermal load" are km (i.e. not mg/m3? and kJ/m3?), the ESI algorithm isn't so-much concerned with the absolute value of these 2 x variables. Rather I suspect, the ESI algorithm's focus is the cumulative distance traveled by the car with either/both variables exceeding an internal pre-set number (these internal pre-set numbers being determined by the relevant industry standard for modern oils)
- A reasonable assumption (IMO, of course) is that the ESI algorithm's decision process for setting the maintenance due flag (and the message on the dash) is if the "soot entry", or "thermal load" calculation is beyond the preset values AND the calculated distance/time values are within the range settings.
- If the calculated distance/time values exceed the maximum range setting without the soot/thermal thresholds being exceeded, I expect that the maintenance due flag is automatically set.
- I'm not sure if the default values for "soot entry" and "thermal load" as factory-set differ with country of sale and/or diesel/petrol engine type (it's possible, I guess)

Again a really comprehensive reply, which makes sense.
Thanks
I have seen a few threads about emailing not working.. someone mentioned (on one of these forums) that he could access the log through the cache but I have no idea where the app stores the cache..
I will try and get some live data and post back.
grateful, again.

PS: Do you know if the Android version OBD11 software supports Quick Share?

finally.. carbon based lifeform got out to take a look 'live' and search Answer 'poor quality'  Thanks for the help NV52! how you change the inspection to done or reset after servicing is another question .. using the Pro Plan rather than just using credits.. I'm interested in doing it myself. OT I had a quick look at my GPF data - having had a so-called GPF blockage which the VW garage 'fixed'. the soot was 33% and zero when i got it back but the figures are meaningless without something to compare to? I looked at particulates and Soot but no idea what the real situation is.. good, bad, indifferent   not being a golf is a guess on this forum but any 'view' is appreciated... Are there Golf's with 1.0 TSi engines in them? I have a good scanner and still no idea what some of the data means.. LOL I hate being in the dark ANY view would be welcome. |

how you change the inspection to done or reset after servicing is another question .. using the Pro Plan rather than just using credits.. I'm interested in doing it myself. I'm not sure which methodology you will eventually use - so for completeness, here's the equivalent list (using the same general categories as per my previous post) of adaptation channels when the routine service methodology is the FIX option: FIX parameter threshold - user applied
- FIX: Reset value for next mileage-dependent inspection
- FIX: Reset value for next time-dependent inspections
- FIX: Max. distance until next mileage-related inspection
- FIX: Maximum time until next time-dependent inspection
FIX algorithm - calculated values
- FIX: Distance covered since last mileage-dependent inspection
- FIX: Time since last time-dependent inspection
- ESI: Resetting ESI > no warning (this channel activates/disables the maintenance due message displayed on the dashboard)
FIX software switch - ON/OFF - ESI: oil quality > poor oil quality
Notice that I've included 2 x channels from the ESI option in my table above - this is because these channels apply to both service methodologies So - if you have understood the rationale for the categories in my ESI/FIX lists, it should be clear how the adaptation channels are allocated to your 2 x quoted reasons for making change: - "inspection to [be] done" - this maps onto the channels in my category: FIX/ESI parameter threshold - user applied
- "reset after servicing" - this maps onto FIX/ESI - calculated values.
The general process for manual SRI reset after completing routine maintenance is two-part - like this (and in this order): - For the time/distance channels in my calculated values category - manually over-ride the algorithm's number by setting both channels to zero- this resets the counters in the algorithm and it recommences a new SRI period
- ONLY after 1. above is completed - clear the error/warning message on the dash (i.e. reset the initiating flag for the warning message in the Dashboard module) by changing Reset ESI: Resetting ESI to no warning
The instructions for accessing the SRI adaptation channels for the purpose of making changes are: - Ignition-ON, Engine-OFF
- Fire-up OBD11 software - plug dongle into car's OBD port and connect to tablet/mobile-phone
- Navigate to the Dashboard module (which has the colored number 17) and select
- Scroll-down and select Adaptations
- Use the search-box to navigate to the desired channel name
- Follow software prompts to implement desired changes
As an example of the DIY "reset after servicing" exercise - these are the screens for the FIX option (alas using now out-of-date OBD11 screens - but the process is the same with the current version software screens): After making the changes above, note the 2nd component of the two-part process to clear the warning message on the dash: " change Reset ESI: Resetting ESI to no warning"
OT I had a quick look at my GPF data - having had a so-called GPF blockage which the VW garage 'fixed'. Are there Golf's with 1.0 TSi engines in them? ANY view would be welcome. Hmmm...... The mk7 Golf uses lots of different TSI engines ("TSI"=Turbocharged Stratified Injection = combination of turbocharging and direct injection) and it's certainly true that the Golf mk7 has many EA211 family engines in its stable
But, I can't recall that Golf mk7 engines were as small as 1.0 liter (it's actually 999ccm) and I'm not aware of any mk7s that were ever built with a 3 x cylinder engine.
However, if a more informed colleague advises otherwise - I'll readily accept that on some part of this lonely blue planet, in some obscure local market somewhere, there could be a Golf with this engine. But in truth, I suspect that a 1.0 TSI engine, which produces 81 KW might ONLY be suitable for the smaller body/foot-print of a Polo (I think)
I don't know the answer to your specific question about the appropriate soot/ash thresholds for the 1.0 TSI engine. Particulate Filters for petrol engines are a relatively new introduction from their Diesel counterparts. My only suggestion is maybe Google "Gasoline Particulate Filters" to get an understanding of typical numbers for these engines - and of course, make sure that you always use RON 95, or higher fuel

my mention here in this and a general thread of not being able to email the text of backups with my android phone (whish is still true) I forgot that I put the app on my Samsung tablet.. used the app only once and forgot about it... Playing the tablet just now; thought.. 'try it'!
Damn if it didn't do exactly as advised above... lesson learned;
might help others.. I'll post this on he dedicated thread in General forum. Doh!

update on GPF data..
still looking at other info but the thing that put me on alert was the high figures of 5600 and 6400 for soot.
The thing though is that these figures are milligrams.. other sites are looking at regen at 27grams.. my figures transalte only to 5.6 and 6.4grams.
Doh!
at least I'm getting somewhere with a reference to work with. Phew!

well there is certainly a lot of information in the Dash Board history.txt file!!!!

careful as she goes...
Thanks DV52. learning bit by bit.
