Hi

I have a 9.3 2007 B284L

the car have 200k km, the engine start, but don't run fine, if i drive it, after 5-600m when i accelerate, i have a blinking CEL, P0300.

Spark plug on the front bank are black, replaced them, coils are new....

got code P0300 P0302 P0304 P0306 and P0018

I guess the origin of all this mess is the P0018, too much long chain, or defect variable phase system ?

i have replace the Sensor and the actuator without any changes ( taken from a nice working engine )

But where i have a question, is about the Tech2 phasing test

i can do the phasing modification on the bank1, when i try to do on the bank2, i ask for an angle, the mesured value is alway 0?....

how can it be possible ? even if the chain is a bit too long, the cam phase must move ?

I am right or i am wrong ?

Cheers

Laurent
