so I carried out the software update at the dealer, error is still present, nobody can give me a straight answer.

Thing is, I am reluctant to open the engine up to check the timing, also the car was tested by everybody at the dealer, road test, etc and it runs perfectly, no power loss, no high fuel consumption, no noises, no idle or acceleration problems, absolutely nothing wrong that could lead someone to think there is something wrong with the timing or chain. Plus it's the B47 engine.

They said I should maybe replace the timing chain "to see if it goes away" but Jesus Christ, the cost is insane.

Bottom line is that if the timing was out of place, the car would definitely run like shit, and since it's not the case, the general consensus is that nobody knows what could this be.

Maybe I will have them replace the camshaft/cankshaft sensors, at least it's not going to cost me a fortune.
