I have a 350 cls petrol and unfortunately have a problem that needs the engine fully stripped for further investigation, so I am looking at a recon engine which might be a cheaper option. I have had the car for about 3 months and have only driven it for about 5 weeks. Have changed gearbox oil and done the cam chain too. Every so often just after start up on low revs it starts missing. All exillarys seem fine. I've been told that's it's possibly an internal shaft with worn teeth. It's at an independent mb garage. So they've said remove and strip engine to look further. Any other feed back would be appreciated. Feeling rather sad about this car it's cost me a lot of time and money and still not sorted.
