Engine will not rev past 3000 RPM

I have a year 2000 E220CDI and the engine will not rev higher than 3000 rpm.

It starts ok and runs ok for a while then the problem appears, quite worrying when your trying to overtake or coming out of a junction and suddenly the car will not accelerate!!

I have recently replaced the glow plugs in the car and the fault first appeared when the plugs were faulty (safe mode) I thought the problem would clear once the plugs had been changed but was wrong. Have tried resetting the electronics but appears to be something else.

Can anyone help - Deiselman has already suggested the MAV, but I dont know what this is or how to find it??

It will not rev past 3000 when at standstill once it has gone into its sleepy mode, somtimes when the car starts everything is ok - revs to redline and goes like a good un!

I have never used the speed limiter, I can get all gears when driving (Auto)

The vehicle is going into limp mode for some reason. The glow plugs only purpose is to help with emissions control, they have no real bearing on how your engine runs wether they're working or not. Your going to have to take it to a garage I'm afraid. The good news is that there will definately be a fault code to point you in the right direction, but to get the code, it's garage time.

I would agree - find an indie nearby who has (win)star and get it plugged into see why.

Mine is going in next week for an idle issue i have at the moment so fingers crossed i will have an answer.

More money to spend on my motor........

i looked at a 313cdi sprinter on friday with same issue and the fuel presure readings well way to low when i checked with my kts box. Changed the fuel pressure regulator (one at back end of rail) and now going like a train..

If you think it could be the Maf sensor, disconnect it and test drive.

How far from stockport are you?

Hiya,

I had an identical problem to yours few months back ( on a C220 CDi), and it was down to a split turbo pipe..so not enuf air was entering the compression and hence the ECU detects and limits the rev to which u can go. Check this out!!!!

I too have exactly the same problem at the moment. Recently changed the MAF sensor. Car run fine, but then goes into sleepy mode, where revs wont go over 3000rpm. If you switch off the car for a while, and switch back on, then all seems to be ok, till next time...............

Please let me know what the solution is when you find out. meanwhile, ill get the turbo pipe checked.

Many Thanks.

a nieghbour also mentioned to me the lack of air maybe the cause of my sluggish performance from time to time..

will find out and feedback on saturday!

I still think you need to reset the ecu via star when you change the MAF.....

I am having the same trouble with a 2000 E320 CDi. Nothing past 3000 rpm, but occasionally it's ok for a minute when it's first started. Replaced TPS and MAF and still no joy. See http://mbclub.co.uk/forums/showthread.php?t=19576
