Hi guys
So as the topic says im having trouble with my 2017 golf sportwagen 1,4 tsi R-line its giving me this faultcode after scanning the car this has been going on for maybe 30 days or so and i have been erasing the code in ODB11 and been googling arround but i cant find a thread that explains to me what is actually wrong so i can fix it.
I live in Sweden so my ODB11 is in Swedish so I have tried to translate the info the best i can to give you all the information that you will need to help me.
Ive printscreend the actual code details in my phone and i can try to attach the photos if needed.
It says its a priority 1 and to be honest i dont really understand the priority order of the faultcodes if 1 is a critical problem that needs fixing right now or if its a problem i can tend to when i have the time? Its only showing in the ODB11 not in the actual car display ...
So its saying:
Central Electronics Supply voltage clamp 30 antitheft alarm
B141013
Status: Static
Priority: 1
Fault Count: 81
Status Clamp: 15 On
Status Clamp 50: OFF

golfwagwan Hi: First - the priority rating of a Trouble Code is part of the "Freeze Frame" information (this is an expanded set of fault data that's available in most VAG cars that were built after about 2003).
Here's how the Priority numbers are defined:
- The fault has a strong influence on drive-ability, immediate attention is required.
- The fault requires an immediate service appointment.
- The fault doesn't require an immediate service appointment, but it should be corrected with the next service appointment.
- The fault recommends an action to be taken, otherwise drive-ability might be affected.
- The fault has no influence on drive-ability.
- The fault has a long term influence on drive-ability.
- The fault has an influence on the comfort functions, but doesn't influence the car's drive-ability.
So- I'm not sure why a fault related to the anti-theft alarm is rated priority 1 - but there's lots of stuff about mk7s that continuously puzzles me!
The fault descriptor is telling you (I think) that the central electrics module (@address hex09) has detected a problem with what's known as the "terminal 30" supply to the anti-theft system. Terminal 30 (or "Clamp 30" in Freeze Frame speak) is a voltage supply that's directly connected to the battery (i.e. it's a "hard +12 Volt supply" that is NOT switched-on with the ignition key). If you think about the anti-theft alarm, it's activated when the ignition is switched-off, so it needs a voltage supply that is not linked to the car's ignition.
I've had a look at the wiring diagram for the anti-theft system and there are 2 x T30 supplies to the anti-theft system; the supply to the siren and the supply to anti-theft alarm sensor (called "G587" "G578"). My guess (emphasis on "guess") is that the latter is more interesting in your case.
I don't have a wiring diagram that is specific to your model, but maybe start with the fuse and trace the T30 supply back through the coupling point on the roof and eventually check volts on G587 G578.

Ah shit thanks dv52 for this detailed explanation that makes me feel alot more safe on the subject.
I will do as you said and check the Fuse and work my way back to see what its all about maybe i will try to charge my battery as well to see if it makes any difference.
Cheers!

Hello all, I have the same error code, may I know if yours fixed and what's the solution?
Thanks!
My car is right hand drive, so I did an eye ball check on the fuses inside the groves box which seems ok...
May I also ask what's G587? Can't find anything from Google...

andrew126 : Hi. First, my bad - I misquoted the Anti-theft Alarm sensor as "G587" when it is correctly " G578" (I've corrected my boo-boo in my original reply so as not to confuse other folk who may read my post) I'm not sure how OP solved his (her?) problem- but here is a very simplified view of how the Anti-theft alarm sensor is wired on a mk7/mk7.5:
As you can see - G578 is a simple 3 x pin device with 2 x power pins and a "data" pin that terminates on pin #15, Socket A on J519 (which is the module that OBD11 calls 09 - central electric) There are 2 x fuses that are used to provide power to G578 depending on the manufacture year; Fuse #6 if the car was built before November 2015, or Fuse #8 post this date (on the "C" fuse block - which on a RHD is located behind the glove box). As I said in my original reply, these are "T30"/"Clamp 30" voltage supplies - so they are live regardless of the ignition ON/OFF status.
Here is a diagram showing the C fuse-block positions on a RHD car: Don |

thanks Don for your information, it was very useful.
i found that i don't have anything plug into the #6 on the fuse box, and on the over head switch i couldn't even find G578. i would conclude that my car is not equipped with anti-thief system~~
so funny enough where is the error from? my guess would be i have applied some apps and some code change in ODB11 for quite some software mods.... and stupid enough i haven't done a full backup.
would you / anybody know which code could trigger the control unit think there is an anti-thief system?
or how do i know what was the original setting if i haven't done a backup?

andrew126 : hmm.......does the central electrics module on your car have a non-zero long-code string? If so, please post-up the complete long-code value
Did you check fuse position #8?

Hopefully, my table makes sense. If not, and to explain - I show the Byte numbers vertically in the first column and the hexadecimal values (as you posted) in the second column - and finally, I show the equivalent Binary number for the hex value (i.e. the 8 x Bits) in the remaining columns.
You can think of the individual Bits in my table as separate software switches that have either an ON (i.e. value=1), or OFF (i.e. value=0) state.
Look at Byte 12 above and note that Bit 3 =1. According to my database of software switches for the central electrics module in your car - Byte 12, Bit 3 tells the module that Einfachhorn_oder_Sounder-Horn verbaut. Or, said in English, this software switch = Simple horn or sounder - horn installed.
Does your car actually have a Anti-theft alarm horn? If not, try setting Byte 12, Bit 3 =0, then clear the error in the module. Does the error return?

Oh thank you awesome the fault is gone and not coming back!
You are totally right that my car doesn't have that horn, it must be me trying to enable the "lock/unlock doors sounds" and checked that bit....

Hi! Sir. Im from the philippines with a Golf mk7 sportwagon. As i reading this i have the same problem code
Voltage supply terminal 30 for anti theft alarm. But my story is different. I ordered OBDeleven when i received via ups the first thing i did is the BEEP VIA SOUNDER but i do have a short horn beep sound factory i want to code it via sounder to make it sound different.
Now what happened is the horn beep is gone while locking. Then i tried everyrhing to get it back like turn on acoustic then activate short beep sound. Still nothing happened. Now this evening i noticed when i tried the panic button in my key the alarm sound is gone also. Then when i watch youtube most of they do in obdeleven is via long coding and i dont have that option. I spend many credits to make it back but sadly it cant. But some other things work like mirror dip,urban joke,interior fade in fade out lights.

Claudiu: I don't have a fuse diagram for a MY16 Turan - my diagram above was specifically for a mk7 Golf. Notwithstanding that both cars have a MQB platform, I doubt that they share the same fuse locations. If you can't access a fuse-diagram for your car - I suggest that you use a multi-meter to determine which (if any) fuses are blown. Don

Don, thank you. I will try that then. And how to change fuses? Doesn’t matter if battery is connected of must be disconected first?

claudio : NO, it's NOT necessary to disconnect the battery when checking fuses and it's also NOT necessary to physically remove the fuse either. There are lots of video's on the net describing how to check fuses in situ. like this:
