1.4 TFSI engine problems

[Martin666]

Hey,

I have a problem with my car - interrupts and loses power when accelerating. After connecting VCDS I had error : misfires 2 and 4 cylinder misfire, cylinder disconnection disabling error 004874, fuel rail system pressure and boot pressure regulation.

I start with replace spark plugs, coils and a fuel filter. After a few days I have following errors and the same problems with the interruption:

1.000768 Random / Multiple cylinder Misfire Detected
P0300 - 000 - intermittent
2,000772 - cylinder 4
P0304 - 000 - misfire detected - intermittent
3,000665 - boost pressure regulation
P 0299 ​​- 000 - control range not reached - intermittent
4. 004874 - cylinder disabling
P130 A - 000 - intermittent
5. 00135 - fuel rail system pressure
P0087 -000 - too low
6. 008851 - fuel pressure regulator valve N276
P2293 - 00 - mechanical malfunction

I have new timing belt.

Have any of us similar problems?

You dont say what year your car is but models prior to 2012 can have piston issues therefore if yours is from that era then a compression test is worthwhile. Have a search on the forum as there are many threads on issues with the 1.4 twincharger engine.

Your comment regarding the timing belt puzzles me though as I thought that engine had a timing chain as opposed to a belt.

Keep in mind when I had my wossner forged pistons installed the mechanic said my piston rings looked like absolute shit and he said they were leaking quite a bit of oil already yet a compression test I did 3-4 weeks before that came back perfect.
