Mercedes C350 2010 - Limp and only changes to second @ 3000 revs - what's wrong with it?

Asked by Jul 20, 2018 at 10:06 AM about the 2010 Mercedes-Benz C-Class 3.0TD C350 CDI Sport (231bhp) CDI BlueEFFICIENCY Saloon 4d Auto

Question type: Maintenance & repair

Mercedes C350 2010 - This car seems to have a gearbox problem of some
sort. The problem is intermittent - but now and then when I drive it from
standing still, the car will rev to 3000 revs before changing to second and
have no power. There is no warning lights, no engine light, but the car is limp
and has this high gear change from 1st to 2nd. When I park and start it again
later, it might be that way, or it might not come back for a few days. Any ideas
what this is about? The car has around 64,000 miles on it and a full-service
history. I've also had the car's log looked at and nothing has really come up
there that explicitly points out what the problem is.

Hello mate I have the same car and it is doing exactly as you described above.. Did you manage to find out what the problem was ?

Yes, after a long stint of fixing issues that came up before the root cause we found out the rubber valve into the turbo was put in incorrectly prior to purchasing and a flap had developed that blew the turbo. It was pretty expensive.
