A friend came past me yesterday with his early 1991 500e to ask about a problem he had with his car.
With kickdown or normal acceleration, it does not want to exceed 5500 rpm.
Its like a rpm stop.
Which also means that it does not want to shift to a higher gear on kickdown.
He has had the car on troubleshooting and they suspect it's this one
When I look at the number, it seems that it comes from a w140?
And it looks quite different when compared to those in my 500E and E420.
The car goes well otherwise, idle silky smooth, accelerates without a doubt.
Switch gears without slipning or slaming the gear.
The only known fault is that the cruise control does not work at all.
A few years ago the gearbox was refurbished, the upper wireharness was replaced and also distributor caps.
The workshop has read error codes but I dont not know if it gave something.
