Errors on vw 7 after change steering wheel

[momo94tn]

Hi, i have various problems.


I replaced the original steering wheel with a new gti style one with new buttons, the center button no longer has the CNL button so I can't set the cruise control speed and I think that's why I get the EPC error on the cockpit (just replaced because I had the analog one , I bought one on aliexpress to which I put the original motherboard on the aliexpress cockpit ). I also replaced an ainavi car radio which also supports the original car functions like cruise control, automatic headlights etc..)
I would like to understand these errors from what are given. The cockpit speaker I put in. The light/rain sensor I think doesn't work anymore because the voltw headlights turn on only the left ones and the windshield wipers don't work automatically with rain with adaptive speed but work normally as on any car without sensor. If anyone can help me I thank you because I am desperate. I would like to understand if I can code the new button to make it with the CNL button for cruise control.

New steering wheel all buttons working Except the button in the middle as it is different from the old one as you see :

hmm......... it's simply not possible (for me at least) to understand the breadth of changes made to this car (which appear to be not insignificant) from the data provided. Also, posting-up snippets of 3 x SCAN reports is more than a tad confusing!! I suggest that you post-up a copy of the current SCAN for this car COMPLETE and NOT EDITED in any way - as an attachment.

Also, I'm not sure, but I think that you are saying that the dashboard module was replaced on this car to an AID version - is this correct? Please provide details of the new hex17 module

Also, the Gateway module on this car is complaining that it can not talk to the Infotainment CAN bus. What changes did you make to this CAN bus?

Good evening, thank you very much for your response. The changes made are: change cockpit with a plug and play one bought on aliexpress, a custom GTI style steering wheel with buttons provided by the seller ( the buttons work, only the CNL button that I had in the old steering wheel is missing that's why I can't use the cruise control but I can use the speed limiter that doesn't require the CNL button and definitely various errors including EPC on the dashboard I think is related to the fact of the steering wheel change with the button on the left side different from the original ). I also put an ainavi car radio made specifically for the golf 7 with two dashcams connected to it with related adas and I also put an external dashcam connected to the fuse box for parking mode . I didn't do any coding , I disabled start and stop , I adapted the new battery , I think the problems you complain about the infotainment canbus is related to the car radio since it has its own canbus I don't know . Other than that I never touched anything in the ECUs or did any coding , I don't have a readout of the car before, but I tell you I had no errors before this big job, the only errors I had were those related to the light/rain sensors .
Auto-hold works sometimes I don't understand why it only works when it wants to and also the car fuel cap rarely closes but most of the time it stays open it doesn't close electronically .
I am very ignorant in this matter I did not understand your request , thank you very much again for your answer .

hmm........I have absolutely no doubt that you understand this project in fine detail - but alas, I do not!! 

Let's start with what you are calling the "cockpit". 

I assume that this car was built with a cockpit that used the normal mechanical 2 x clock-dials -is this correct?

I have no idea what you mean by "change cockpit with a plug and play one bought on aliexpress". I don't know how many different products Alliexpress sells - but it has to be a very, very large number. Please provide a web-link to the ACTUAL cockpit that was installed on this car, and please provide details of the factory installed cockpit (from an old SCAN) - so that I don't have to guess which modules were used!

Your screenshot shows that this car now has an Active Info Display (AID) cockpit. 

Again, without knowing anything about the Alliexpress device - I'm almost certain that the new cockpit is NOT (emphasis on "not") an OEM module. This means that I have absolutely NO confidence in the seller's claims about "plug-and-play". EVERY seller of non-OEM equipment on the web advertises their products as "plug-and-play"- but the seller simply making the claim doesn't mean that it's true, especially for sellers on eBay and Allixpress).

As an example of my skepticism about the Alixpress module: if you had retrofitted a true OEM AID cockpit into this car - you would need to deal with immobilizer/Keying and Component Protection errors. I assume this didn't happen with the Allixpress module! 

Also, the information signal for a true, OEM version AID module for MQB platform cars (like the mk7/mk7.5 Golf) is provided via VW's optical fiber facility - which is called "MOST".

So, if this car was factory built with the normal cockpit - retrofitting a true OEM AID cockpit would also involve fitting optic fiber cables AND enabling the MOST signal. This is normally done by coding changes in the car's MIB - which is part of the infotainment CAN bus. 

Maybe this is the cause of your U006500 - CAN infotainment no communication error on the hex19 module - but this is a complete guess because the information provided is far too general!! 

You really do need to appreciate that getting advice on a forum is critically dependent on the respondent (in this case, a forum member who lives in Australia) understanding the specifics of this project. Without this detailed understanding - this forum process simply doesn't work for such a complex situation. alas!

thank you for your reply . The cockpit is this : a.aliexpress.com/_Ev0GQHx
It should be an AID, I detached the analog speedometer logic board (with the mechanical hands as you said) I attached its motherboard behind the Digital Cockpit with its speaker.
I can upload pictures of the one with the hands there I have it in a box in the garage if it can be useful, otherwise I have to unplug everything again put the old one and do the diagnosis, as soon as I get the new obd I ordered red I will do the full scan you asked for

[dv52 (Australia)]

hmm...... as I said, the Allixpress cockpit is definitely NOT OEM equipment!! I nave not previously seen one of these "bolt-on" cockpits and it's anyone's guess how they are designed to integrate into the VW OEM environment.
