Hello all,
My beloved C270 started to lose power intermittently last week and, having looked at this forum, I thought it sounded like the MAF sensor was on the way out and the car was going in and out of limp mode as a result (not revving beyond 2000rpm ish). It's been into the garage today (independent) and they have run diagnostics and come back with a few codes, but no real diagnosis of the problem.
The codes are:
P1470 charge pressure negative control, charge pressure low
P1222 sensor 1 signal voltage high
P0100 bank 2/5 hot (?) mass air flow (missing word - mechanic's illegible handwriting!)
P2001 N15/3 ETC control module faulty
P2600 circuit 87 voltage too low
The engineer advised that the first 3 codes relate to the turbo and MAF sensor and the last 2 codes relate to the gearbox, but he wasn't sure whether the MAF fault and resultant loss of power was the cause of the gearbox/turbo faults or the vice versa. They have recommended going to a diesel specialist to investigate further as they aren't MB specialists.
Any advice would be very gratefully received as I have a sinking feeling that this sounds expensive!
Thanks,
Adam
