Hello,
First of all english isn't my native language, so i can do some mistakes.
I bought my A2 with some little problems. it's a 1.4 petrol BBR engine.
I have a trouble when i drive it slowly i have some splutter.
When i log with VCDS i see my STFT change very fast between -10% and 10%
I changed the two oxygen sensors (with original NGK) and it doesn't change.
I clean the MAP sensor, thottle body (with calibration) but it doesn't solve my problem.
I saw on my EGR valve a short hose clogged, i think it is an air vaccum but i did't found where it was plugged in the past. Do you have an indication ?
I suspect a intake of air, because when i drive it faster i didn't have this problem. Is it correct ? I tried to spray my engine with brake cleaner to try to find a hole of bad gasget but the engine RPM doesn't change. Does someone have this trouble ?
Thank you
