- 2012 Mercedes Benz C207 E350CDI, L322 Range Rover.
Evening all.
I have recently purchased a 2012 facelift C207 E350cdi 7g+ 265bhp.
I have previously owned a 2011 W204 C350cdi pre-facelift model 231bhp and covered over 100k in it, so am familiar with the engine and regen process.
The new car has in the past week, twice gone into a strange mode. Revs increase to around 2000 before a gear change, and the car is dropping down into first when slowing or stopping. There is also a significant loss of power and even when the accelerator is pushed down, very little happens. On a road when the car would normally be in 7th, it is holding in 5th and will not change up when the flappy paddles are used.
There is no tell-tale hot rubber smell and lots of heat coming from the underside which usually signifies a regen occurring.
Earlier this week when it first happened I drove around for half an hour to let it do its thing, but it did not drop out of this mode. The following day it was back to normal. Same again this morning; all normal, however this evening it went back into strange mode, so I drove it onto the motorway and covered 40 miles at 60-65mph, yet this had no effect.
I had the car serviced last week and the gearbox oil and filter changed using a Mercedes service kit. Low ash oil used.
The car has covered 84k with 1 owner and a full history.
Any ideas?
