Dear all
I have a W221 S320 CDI (V6), 2008 model, 56000 miles. Purchased secondhand from Mercedes dealer 2 yrs ago and FMBSH.
Yesterday, I was driving on the motorway at a gentle 70mph, accelerated gently to move lane, experienced a small judder (I didn't hear sounds but had the music on) and the car then started to loose power, engine management light came on. I moved on the hard shoulder and as I came to a stop then engine cut out and would not start again.
Car was recovered and have taken it an independent Mercedes specialist (via a recovery truck). Breakdown service thought it was the fuel pump problem. Merc specialist has taken a quick look and thinks it is more serious than fuel pump problem and thinks crank not turning probably due to a timing chain failure-he is fairly certain the timing chain has come off.
The mechanic says serious engine problem, need to open up the engine to have a look internally, says possibly needs new engine or at the very least an engine rebuild. Mechanic quoting £300 to open engine up and look at cylinders, valves etc. Is this reasonable?
I am a very gentle driver and service the car meticulously and I cannot believe I would develop a serious engine problem at 56,000 miles.
Any ideas what this could be and what the best way to proceed would be
Is this a possible/common issue with the 320 CDI engine (V6)
I would be extremely grateful for any help or advice you can offer
Many thanks
