Hello.
I have Audi a4 b8.5 1.8tfsi and Check engine light on. A lot of mechanic tell me that is timing chain, I change it but still same problem P0341 code.. I dont know what to do.
@slavishas
Please be specific, what exactly have you changed so far? The timing chain or the camshaft position sensor? If the timing chain and camshaft sensor were changed, then the mechanic probably installed it at the incorrect camshaft position (i.e. camshaft is off timing) which is pretty dangerous for the engine.
Now few days ago every morning when I turn on my engine its scratches/rough a lot and after when I drive it turn it off and start again its not so strong that rough... what can be?
Well realize all these are endless money pistols they age and if a guy told you it needed a timing change it didn't fix the problem I would demand my money back from him and go elsewhere or take it back to the guy and said I paid you all this money fix my car for free or give me my money back
but basically if you want great advice never buy another one of those German piles of junk again if you value your money over time
When I make diagnosis it comes “Short term fuel associated to bank1 sensor2 99.2%“ and when I push on the gas pedal come also Lambda - bank 1 sensor 1(wide range O2S): 1.999” and Fuel/air commanded equivalence ratio: 1.543”
What should I do and change/fix first?
Thanks a lot.
Wish you all best.
