Hi I have a question my car have a very uneven idling and the car makes vibrations on idling, the idling moves from 500-700rpm. I found that this problem was pretty ordinary on audi A3. So I just wonder how I should solve this.
I am buying some new sparking plug and will change the oil. But what more could I do to get rid of the problem. (Change LMM?)
I have a Audi A3 2.0FSI -2004. And when I check whit VAGCOM there is two codes on the engine that worrys me.
2 Faults Found:
16825 - EVAP Emission Control Sys: Incorrect Flow
P0441 - 008 - Implausible Signal - Intermittent
18322 - Pressure Sensor for Brake Boost (G294):Implausible Signal
P1914 - 008 - Implausible Signal - Intermittent
Readiness: 0000 0000
What could that be? The EVAP most have something to do whit LMM but the pressure sensor for brake boost does that have any thing to do whit my odd idling? Appreciate every help I could get Thx
