Hello everyone!
I've been fixing my A2 now 2 years in. Cause time apparently don't grow on trees.
It all started with someone thinking it was a good idea to change just one out of two timing belts.
Had it standing at my brother for a year, "outside" before I had time and place to fix it.
Engine runs fine when cold but triggers ENGINE, ABS, TC, EPC after a while and gets a ruff idle until it settles for 1100 and I can't rev the engine anymore. Notice a weak rear light, maybe just a bad ground to the rear light. Got new lights bulbs just to be sure its not just the bulbs. Lights works fine now, still same engine problem / ABS lights. Disconnected the rear light left and right just to check (Middle still connected). Engine now runs like it should and throws just EPC after 3km trip. Engine idles just fine.
Disconnect the brake light switch instead. Same results as disconnecting the rear light. Disconnected the ABS module to see if that was the issue but did no difference.
Tried a new brake light switch but did no difference.
Can't see any damage on the cables I looked at so far.
ODB2:
Engine
17912 Air intake system leak detected <-- goes away then I remove rear brake bulb
17961 Altitude sensor signal/intake manifold pressure Implausible ratio <-- goes away then I remove rear brake bulb
ABS
01314 Engine Control module
This sounds similar but I can fix it with removing the rear brake bulbs.

Hi All, I've been attempting to sort this out having read the wealth of info on the forum but to no avail. It's my wife's car- a 1.4 petrol, manual SE (?) 2000 with about 95K. Once warmed up and when you put your foot down I get ABS, EPC and the red warning circle with exclamation mark in...
