Car suddenly changing gears at high revs (3000rpm)
Hi all. Wondering if anyone else has had this issue. My C220 bluetec 2015 suddenly started shifting gears at high revs. Also noticed in won't go into Manual when I use the flaps nor will it change manually until it reaches 2500rpm (approx) minimum. Any ideas what could be causing this? My first thought is the dpf filter. Thanks in advance

Sounds like EGR valve issue - mine had a similar issue. Any check engine lights on ? If not get hold of a OBD reader (this one works - ) and see if there are any codes.

No engine lights on.
I did speak to the seller and they have advised that it’s a software update which he will try and arrange.
The seller is a genuine honest trader so I’m confident he’ll get to the bottom of it. Will post the fix on here should it work

Did you manage ti solve it?
I have a W212 of 2013 and it happens daily that car changed gears in high revs. When it does that I can’t speed up (no power) and can’t change gears manually.
MB specialist understands nothing since scanning shows nothing.
Please let me know if you managed to solve it
