Hi Guys
I've had a good lurk for the past year or more and have found this forum most useful. I have a C180K Classic SE - 03 plate which I think makes it a W203. A few weeks ago the engine check warning light came on. My local garage, bless them, have a plug-in ECU computer thing which gave a list of fault codes stored in the ECU. The main one seemed to indicate that the MAF was the problem. There were several other codes relating to correcting misfire on cylinder 4 I think.
Before the engine check light came on i had noticed that tickover was a bit lumpy. I had also noticed that the car might be lacking power a little. The garage re-set all the fault codes and suggested a wait and see approach. Didn't have to wait long because as I was driving off their yard the engine check light came on again. They plugged in the widget and the code was once again pointing to the MAF. They reset the code and said if it came on again to call back in and get the car booked in.
The other day the engine stalled just as I was turning a corner. This was actually quite scary as all of a sudden there was no power steering and the brakes didn't work properly. When I restarted the engine the engine check lamp was on again.
Right now the check engine lamp comes and goes but there is still rough tick-over. However, and here's the point of this note, my fuel economy is not lower than normal. If anything I'm getting a better mileage than I would normally get. Today I had to drive 70 miles from the airport to home and the engine check light came on when I started the car. The trip computer seemed to be telling me that I had done an average of 41 mpg for this trip, which is rather more than I would expect.
It does look like I'll have to bite the bullet and get the MAF replaced, but before I splash out 400 for the garage to fix it, is there anything else it could be ? I've just searched the house for the ECU printout so I can tell you the actual code but it seems that my wife has put it somewhere safe
Any advice appreciated.
Thanks
Jim
