My 2001/W203 C Coupe 220CDi has developed a fault where part way through a journey it loses power.
Happens after 30mins/30 miles, car will accelerate up to 70mph on flat - on hills it slows to 55mph. Only first 30% of accelerator travel has any effect, the next 30-100% makes no difference.
Fuel consumption is also worse, c. 37mpg instead of usual 44mpg.
On journey home (8 hours later), all is fine for the about 30mins/30miles and the fault reappears. This repeats every day.
There are no fault lights/malfunctions reported on the dash.
Spoke with an inde MB who through it was the MAF. They said stop the car, remove the key, wait a mintue and any fault code would be cleared and the car would be OK.
Tried this, but the fault was still there immediately I drove off again.
Any thoughts ?
