I've had the same fault in my 2018 Golf R almost since I bought the car new. I recently learned it's just a software bug. https://static.nhtsa.gov/odi/tsbs/2019/MC-10169517-0001.pdf I'm not aware of any ill effect. I've driven more than six years and more than 100,000 miles with that fault...

@DrPeter, @Dana: Key battery comments are valid, I think one of them was low awhile back. However, there's another detail I neglected to mention. During the times we've had trouble getting the driver's door to unlock, the driver's door handle responds to touch. The vehicle wakes up and you can...

Customer (wife) is intolerant of her vehicle being disassembled in the garage waiting for diagnostics and parts, and the technician (myself) is intolerant of having to do a job twice, especially jobs involving relatively fragile interior trim. Puzzle solving for the true root cause is cool, and...

Did programmed maintenance and SRI reset on my wife's daily 2020 Tiguan today. It's been having intermittent issues with not unlocking in response to a door handle touch. There are multiple faults in address 42, for both the locking motor and what I'm assuming is the interior door lock button...

The fault is for the "passenger air bag off" yellow indicator lamp, located just under the HVAC controls that you removed. You may have forgotten to plug it back in.

Not true for any 7th generation Golf that I'm aware of. They are all located above the steering column. https://docs.howtocomma.com/docs/j533-harness-install The only MQB vehicles with combined BCM/gateway are **some** MQB-A0, I believe ones manufactured in South America.

What is the error? Have you tried the manual charging procedure?

No worries. For the record, you are not one of the "memorable counter-examples" I was referring to. There's a couple folks who have planted way, way harder against giving us necessary info. :) Damn, I can't believe I called it. :) Yes, to 14 occurrences question. The date and time stamp are...

With just a few memorable counter-examples, almost everyone is willing to help us help them, once it's explained. Trouble is explaining it over and over and over and over to thousands of people. I wish there were forum automation to look for an Auto-Scan in thread opening posts.

If the OP is careful and lucky, he might be able to use VCDS to prove the service action wasn't completed correctly. There's only a few hundred Golf R sold in the entire country of Australia every year. This service action is relatively recent and applies to a small subset of MY2018 only, which...

True, but completion of service action 34K1 does mean a Volkswagen tech with an ODIS login certified there was no fault code after a test drive. The process changes if it happens after leaving the dealer. See page 18 of your link, which points to Technical Bulletin 2070973 (US). It's NOT clear...

Basic Settings hasn't completed, for whatever reason, or may have been attempted and failed. Have you been here? Go through the measurement and level setting procedure. Can you complete it successfully? If the car is starting out too low, you can (with care) use the manual bleed/charge...

There's a lot to unpack here. First off, I'm sorry your Golf R is having troubles. I own and daily-drive a 2018 Golf R and this post freaked me out, it was the first I'm hearing of the issue. I went and checked that campaign myself, and it doesn't apply to my VIN, so thankfully I'm good. Still...

The auto start/stop button probably isn't considered safety relevant under an ASIL analysis. To summarize, there probably aren't any failures or malfunctions of the auto start/stop button that could meaningfully increase the risk of losing control or crashing. Or if such a risk exists, it's...

It's called end-to-end protection because there is often more than one transport "hop" between the sender and receiver(s) of the message payload. In the simplest scenario, there could be software bugs or hardware-level memory corruption in the CAN gateway that relays messages between CAN buses...

Nice project! I know you've gotten it working already, but I thought you might find this info useful: The CAN arb ID 0x12B that you're working with is called GRA_ACC_01 and it has documentation in opendbc. The byte you refer to as XX contains a payload-level CRC. That's why it varies together...

You've already located the MVBs for steering angle, which is good. Check the steering angle at a standstill with the steering wheel pointed straight. If the steering wheel is straight and the angle sensor reads 23 degrees, I'd ask if you removed the steering wheel at any point (perhaps for...

Yeah I'm not saying it's lots its params, I'm saying I wanted to avoid that. Was asking if there's a safe (no params loss) "reboot me", like what people do to the BCM after changing lighting settings, I forget the details.

It's pretty confused. Here's the most interesting differences. Known good Atlas EPS: IDE02955,System status,Driving mode, IDE03725-IDE03734,Steering Assistance-Support power, -100, % IDE03725-MAS03001,Steering Assistance-Mode,Dynamic, IDE03725-MAS03095,Steering Assistance-Function...

Right method wrong address -- we need address 44 (the EPS), not address A5 (the Lane Assist camera).
