Hi,

I've had a number of dash warnings appear on my MK7 Golf all seem to be associated with ACC/Parking controls and the parking sensors currently don't work. I was advised by an auto electrician that all the controls talk through the front radar and to try changing this first as most of the errors were missing messages. For transparency I have changed the radar expecting to still have some errors but possibly the missing messages to clear. Unfortunately the radar seems to have made no difference and all the fault codes still persist.

Would anyone be able to offer guidance on where to look next, the issues all came on at once and seem to be related but my main issue is the fact that the park pilot error display on the screen coincides with the parking sensors being disabled.

Scan attached.

Thanks

As @Dr Sheldon wrote. Fix those and most probably errors gone. Almost all errors on other modules relate to those two

I did not read your opening post properly !

For transparency I have changed the radar expecting to still have some errors but possibly the missing messages to clear. Unfortunately the radar seems to have made no difference and all the fault codes still persist.

You replacing the Radar has for sure added the "COMPONENT PROTECTION" Errors.

Put the old one back on and they should disappear. Is that correct ?

Is the component protection likely to be linked to

0297 - Steering Angle Sensor

I have put the original radar back on and followed some instructions found on the forum to check/calibrate the steering. I have cleared the DTCs and then taken the car for a drive. The dash errors still persist and have no working parking sensors, the faults for the steering angle sensor have stayed cleared and the ACC module now states ACC main switch off.

I can’t be sure without being at work but the new radar sensor looks like it is the wrong one, I get it as 3QF 907 561 A. Without having the new sensor realigned on the test stand, you can’t trust the values or missing message errors, U1121 is starting to get to me! Is the replacement sensor new from TPS (£598.80) or a stolen Bay special? Without removing the component protection, you can’t even set up a new genuine sensor, this problem is becoming a regular Golf 7 PITA. Most people we diagnose this for unplug it and live without and TWO now we have replaced have been stolen, I told the last chap a few weeks ago to get on eBay ASAP and he could probably buy his own back so the component protection wouldn’t be a problem…

Hi Crasher, yes it was bought from a salvage yard via ebay. The donor car (if correct) was 2020 so two year newer. Are you saying brand-new one from TPS wouldn't have the component protection fault. I'm loathed to spend £600 on a new radar though if this is not the issue. I'm not fussed about the ACC but the lack of parking sensors is a pain, these seem to go hand in hand unless i'm missing something?

The 2 faults for "Trailer" in 10: J446 & 13: J428 can cause the Dash Lights to Persist and if it thinks a Trailer is attached it should turn the Parking sensors off.

There is a Viable relationship there so we can be sure that the fault is in that area.

Do you have a trailer module ?

If not then your car thinks it has !

The car has no towbar or wiring for a trailer. I assume there’d be no trailer module in this instance. If it thinks it has one and doesn’t this could account for the missing messages?

I've looked to see if the trailer module was selected in the installation list

[Select]
[19-CAN Gateway]
[Installation List]
69-Trailer

It was not ticked, I selected it saved coding and then removed it, save coding to see if this would update it.

The trailer fault still persists, is there anywhere else I would need to look to see if the car is setup to expect a trailer?

There's almost certainly a bit in the ACC sensor's coding that tell it whether the car has a trailer hitch or not, and since this is a used sensor, chances are that bit is set because the car it came out of had a trailer hitch.

Hi Uwe, this is the original sensor installed. I also have an original scan showing the issue pre trying the 2nd hand sensor. Not sure if the trailer module was enabled prior to the fault appearing but this is not something I have enabled or had issues with prior.

Incorrect trailer coding kills ACC

haha zu geil :D

And what is killing a functional ACC in the first place? Replacing it and triggering Swap and CP.

Well, not really clear from OP’s description. Something something, ACC does not work, advice to replace radar, again something something, original radar in then maybe a crash damage car or not, something about trailer not installed but is coded in several modules and so on.

The trailer fault still persists, is there anywhere else I would need to look to see if the car is setup to expect a trailer?

I would run a new scan and then target the modules that are complaining about the Missing Message - That seems logical to me ?

Hi Crasher, yes it was bought from a salvage yard via ebay. The donor car (if correct) was 2020 so two year newer. Are you saying brand-new one from TPS wouldn't have the component protection fault. I'm loathed to spend £600 on a new radar though if this is not the issue. I'm not fussed about the ACC but the lack of parking sensors is a pain, these seem to go hand in hand unless i'm missing something?

You are lucky it is only £600, earlier ones were nearly £2000. You can’t mix and match the sensors in that manner, between 23.01.2017 and 30.07.2018 alone the part number (with software) changed three times, over the next two years I can’t be bothered to work it out. Component protection is not a fault, it is a system to prevent stolen parts being sold on places like eBay. The future of cars with all these interlinked and P0211 missing messages faults have convinced me to pull out of working on modern cars by this time next year; it has become too complex, costly and litigation liable to be comfortable anymore and owners/customers still view the costs and the techs value as if it was a Golf 1 from the 80’s. What people will do to cars to keep them going really concernes me, if someone is unwilling to spend £600 on a car’s safety systems when it is worth what, £15k+, what’s next? £200 on a high voltage system cooling pump on a 10 year old EV? :banghead:
