E240 Frustrating Acceleration Problem - Driving me crazy!
Discussion
Hi All,
I have a 1999 E240 Estate (W210?). It runs and drives well and the gearchanges are 'normal', as long as you use less than 3/4 throttle. It has no problem reaching high motorway speeds, and pulls well at low/ mid revs in all gears. The gearbox was replaced (or had a complete overhaul) only 10k ago.
The problem is when you try to accelerate hard, like you would expect to do when overtaking.
At WOT he car struggles to accelerate smoothly, and really bogs down at anything past 4000rpm or so. Under hard acceleration it will kick down, but then the gearbox holds in gear rather than changing back up. By backing off the throttle considerably and letting the revs drop, it then will change up.
It is becoming really frustrating, so I hope someone out there can help me.
Cheers

MAF here too! Only knew I had a problem when trying to "make progress" along the M3 in the early hours one night. Car (E430) drove perfectly at lower engine speeds. I have heard that VW/Audi units are the same and may be cheaper.
Good luck

I would'nt chance it. I have been told that using the wrong unit can cause serious damage to the ECU. Good luck
