I have a 2017 North American Mk7 Golf R. I physically removed the car net box and want to tell the car it is not installed. Searched Gateway 19 for telematics under coding and adaptions but could not find it. Can someone help me disable the telematics unit? I'm assuming it's in the long coding but obdeleven doesn't have a description for the bits.

Instead, the list of registered Gateway modules is separated into an entirely different area. To access the Gateway list, press the white-pencil-in-the-red-box in the screen below Don

Wetmacular: I'm not sure why you are removing the telematics control unit but here's my simplified wiring diagram for the module showing why you are getting the two errors: So, the thing to note is that there are basically four external components connected to the telematics module (again, the diagram is a cut-down version of the complete installation- so lots of other connections in reality): I'm guessing (we don't have this "nanny" facility installed in our cars down here in Australia), but there will be code/adaptation settings in the Central electrics and Info Control unit 1 modules matching the physical connections shown in the diagram (I think). The other interesting consideration is how the (software) removal of the telematics module from the CAN bus affects the telephone microphone (does this still work for mobile telephone calls?) and the GPS aerial (does the SATNAV still work correctly?). The reason for my mentioning these two external components is that with the telematics module registered with the Gateway, data from the microphone and GPS will be transferred from the telematics module to the modules @ address hex5F and hex09 over the convenience CAN bus - but when the telematics module is removed from the Gateway list, this data flow stops (this could be the reason for your 2 x DTCs- I guess) Don

The Car-Net telematics box is located behind the instrument cluster. It is a self-contained computer with a decent processor, 1 gb of ram, has its own GPS and cell connection, DSP chips, and some field-programmable gate arrays. It allows 2-way communication with the vehicle and their printed terms are ominous. At a minimum it transmits vehicle health, location, speed, microphone audio, and information after a crash. It can disable the vehicle remotely, unlock doors, flash lights, honk the horn. If VW can do this remotely so can others and it's a parasitic drain on the battery. First 6 month's of Car-Net service are free then a reoccurring fee. If the Car-Net box is removed, the GPS works (from MIB2?). Bluetooth works. As you cleverly postulated, the microphone is lost but shuko on golfmk7 and vortex Golf/GTI VII removed the box then jumped the pins shown on your diagram to restore the mic for bluetooth calls. He created the last photos identifying the PCB components. I suspect your reasoning for the 5F and 09 faults is spot on. I quickly checked all adaptations on 5F and 09 but did not see anything obvious about the telematics unit, gps, or microphone. Will have another look later. Maybe it's in the long coding?

I hear what you are saying, but I'm extremely surprised that the GPS information is still getting to the hex5F unit without the Telematics module registered on the extended CAN convenience bus! Here's the wiring diagram for the roof aerial for both vehicles with straight SATNAV and those with the Telematics module: Notice the pin connections are different - ulness there are actually two separate roof aerials for the Telematics fitted vehicles, it doesn't make sense (well.... not to me at least!!)

I'm not sure what my shark fin antenna serves but someone mentioned it has 3 coaxial connections and 3 antennas. Two are horizontal receivers and one is vertical. The flesh colored square appears to be a GPS antenna. Checked again today and the SATNAV works without issue. There must be a different GPS in the MIB2 HMI or its brain in the glove box.
