I have a 2011 550i xDrive M Sport. 176500 kms. Nice car. One owner with lots of history did the usual, oil change and check over by a competent technician, however.
The timing chain may have broke. I was not driving at the time so not sure what happened. Towed to a BMW specialist who said the engine does turn left and right a little but has a clunk. Had it towed home and my tech has yet to look at it. I don't think he's the right person but......
So is it a new engine or a rebuild?
Whats it worth non-running?
I see complete engines for around $5000 and a rebuilt block here in Canada for $1500.
