Hey guys!

I have some problem with my project..

I tested my Fabia with auq 1.8t, and everything seemed okay.

But i noticed, the turbo gauge says its boosting with 1.3 bar.

So i turn back to go home, but after i stop, the car stalls.

Started the car, and only 3 cylinder working out of three..

I have new bosch tfsi coils and ngk pfr7s(same to pfr7q i think) plugs.

The overboost problem was caused by a missing earth from the n75(maybe), but now i got a Camshaft Timing Adjustment -Short to Ground fault code..

And the car starts only for 2 sec.

Anybody can help me?

I'm really sad, because i can't use my car about half a year..

Is the 2 second start possibly an immobiliser issue. On stock cars they usually start and then cut-out after a second or 2. What boost are you expecting as 1.3 bar is only 19psi so does not sound excessive.

Some hungarian guys says the stock pressure is 0.7, so i dont know.

But its not an immo issue, because i turned off the immo

And not every time 2 sec, some times 3-4

Fuelling issue perhaps? Fuel pump, fuel pump relay etc etc.

Fuel pump working, replaced the pump and the same problem

But my biggest problem is what is the Camshaft Timing Adjustment fault code.. 😕

Cam position sensor probably, you should check the wiring.

Wiring okay i think.

The yellow/balck wire is the negative wire and the other(green maybe?) Is the + or no?

Black/Yellow is normally a supply wire not a ground/negative,  ground/signal grounds are normally Brown, Brown/white, Brown/yellow 

Thanks man, camshaft fault code gone now

But now i replaced the crankshaft sensor. And now the car wont start.. its a brand new sensor. There is difference between the 1.8t arx, bam, auq crankshaft sensor.

I dont know why is not working..
