Sounds like you're getting there 🙂 keep us posted if the key reprogramming fixes the issue.

Will Definitely need to Drop the bumper corner which is not to hard a job, I would source a 2nd hand light as while getting the headlamp Lense of is physically possible it is almost impossible

This is a example of what I mean

Hello! I have a problem with my 2013–2016 Audi A4 B8.5 2.0 TDI 177 hp Quattro 6-speed manual. I’m getting the "Steering Lock: Contact Workshop" error on the dashboard. In VCDS, the error appears in 05 - Acc/Start Auth. as 03026 - Enabling Terminal 15 with faults 006 and 009 (Short to Ground / Short to Plus). The ignition turns on, but after pressing the clutch and pushing the key again, the car doesn’t even attempt to crank. Instead, it turns the ignition off. If I hold the clutch pedal down with the key in the ignition slot, it eventually starts after multiple attempts—sometimes on the second try, sometimes on the 20th. This error and starting issue are intermittent. If I clear the error or disconnect the battery, it works for 1–2 days (or less). The battery is fine; it was replaced last year and coded to the car. The steering lock also functions correctly—the wheel has never locked or failed to unlock. This issue occurred last year. The mechanic opened the plenum chamber under the windscreen, cleaned the cables in the junction box (center of the plenum) with sandpaper, and sprayed them with contact cleaner. I repeated this process this year, but it didn’t help, and the cables showed no visible oxidation. Worth noting: I’ve had drainage problems in the plenum chamber. Water pooled there because the drains were blocked. The issue happened last year during heavy rain and has recurred this year under similar conditions. Here is the VCDS scan for the 05 - Acc/Start Auth. (BCM2) module: (If needed I can provide a full scan for the car) Address 05: Acc/Start Auth.

You need a good auto electrician for this not a workshop, from your description I would think your steering lock module is not powering up on request and this module is part of the security handshake required to enable engine crank,

I've been driving automatics for more than forty years, even the slow and sluggish changing ones, because I am a lazy driver. I never understood why folk would tolerate a metal pole sticking up from the floor that they had to wriggle around like stirring a pan of porridge just to make the car go from A to B.

Had my ATF Fluid and filter/pan at a ZF Specialist at 80000miles. I know people say ‘sealed for life’, by the manufacturer ZF recommend every 8 years or 80000 to 100000 miles. decided to stay on top of this as I am retired, bought the car from new and want to keep it long term. They had to undo part of the sub-frame to access the gearbox oil pan.

Thank you mate ,after a bit more digging and a bit of a disagreement with a guy on VCDS it appears I dont have this module in the car so this I why I could not access it , STG 13 > Coding > Byte 3 > Bit 3 Activate refers too (auto distance regulation) =adaptive cruise control ,as I dont have this on the car I dont need this section so all sorted Cheers Jim
