My 2001 E320CDi estate has not ran correctly in the 10 months i've owned it. I have had the EGR replaced, car ran fine for about 2 days then sluggish again. One of the acoustic flaps in the intake manifold was found to have seized ( new manifold £600 odd) so they have been wired open. The car has been fully serviced 6k miles ago; starts easily with no smoke and returns 35+ mpg. It has now done 106k miles It runs very smoothly, changing gear up and down correctly but now will not rev past 2500 even if held in manual mode. This was originally an intermittent fault which would clear if you stopped then restarted the engine. Now it happens all the time. If the throttle is floored you get the "EL Power warning" message on the dash which resets when you switch off. Is this of any significance or due to the acoustic flaps not now operating correctly. Any advice will be much appreciated. I have totally lost confidence in the car and MB in general and don't think i will be having another one. The rust and general unreliability have been too much. In 10 months i have had a faulty coolant thermostat, passenger seat air bag sensor failed, air con condenser fail (still not done), dash pixels (fixed by me), front arb drop links (at least cheap), EGR valve and expensive service. On top of this there has been depreciation of around 50%. Yes, in only 10 MONTHS. If anyone wants a bargain Avantgarde in silver with 7 seats, heated black leather, f+r sensors, Y-reg, please PM me. It is also due to go in for free rust repairs on 1st dec in cheltenham but i can't wait that long!!!!
