Vcds code 18265

Post by carlssonaero » Fri Jun 20, 2025 11:53 am

Can anyone help diagnose this code. It suggests abs but the module has passed its test with ecu tuning and all the sensors seem ok too. Many thanks
Kind regards

Are all 4 tyres the same with a similar amount of wear?

That's a code that's caused by dodgy info from the ECU to the ABS module. Most usually caused by a mixture problem, as odd as that sounds. I'd check for vac leaks or an incorrectly seated air box (extremely common).

It could be caused by a dodgy map if you've been dabbling. If this is a new fault and you haven't changed anything then I'd look for a leak. You can check the trim with the Vagcom. Group 32 on the ECU IIRC.
