It's really a miracle something far worse didn't happen.
Query: why was the tensioner replaced 30k km ago? And how many km on the odometer now? My consern is that something done during that repair caused the lack of oil/tensioner pressure that usually is the start of this type of failure.

Well I bought the car from a man last year who had bought the car with broken vanos and he has replaced the vanos and reset timing just to see if he was able to fix the car.
It has worked just fine until last week when I heard the strange sound and I thougt it was the waterpump on the way to fail. I donīt know why they changed the chains, tensioner etc but something must have happened. I think the odo is about 18700 swedish miles.
There was a lot of debree from the broken solenoid and chain guide in the filter of the upper vanos solenoid.
I dont think there is lack of oil pressure in that case it should have jumped the vanos sprocket, there could be a broken link on the chain to have seen that on one car before. Well it will be interesting to see what has happened.
