hey guys,
i've got W201 with 2.0 AT engine, the car reaches 160 Km and dont want to go more than that. nothing wrong with the gearbox and engine it self.
most people told me that its differential problem.
so is there different kinds of differentials and is there a low speed one and higher speed differential like BMW or not

thanks alot and waiting for you feedback people coz its really annoy me so much

There are several differentials with different gearing.

For your vehicle I believe the gearing is 3.64 for the 2.0 with the automatic transmission.

Crawl under the back end and scrape off the muck on the left hand lower corner of the casing that sticks out from the side of the cover to see the final drive gearing.

Don't leave that there - I'll take it to bits!

i changed the differential with another one after i changed it that problem happened, plus aint the 3.64 one is for the 5 speed manual engine, if im not mistaken

I think the 3.64 is used on the 5 speed and the automatic transmission and the 3.46 (what I have) is for the 4 speed.

But I might be wrong about that. (Though I'm not wrong about what I have got - that I know!)

Anyway if you've just changed the differential to one with a different gearing then your speedometer won't be reading the correct speed. Speedometer and differential are matched.

Check real speed on the flat with GPS.

(And crawl underneath and check the final drive ratio)

i don't doubt what your saying, i just recently bought the car, and im trying to understand everything about it, the engine is just in prefect condition but it just dont want to go over 160 km and i really appreciate your answer and help.
and the final drive ratio where is that written sorry i cant find it.

Here's the thread where I asked the same question a few years back

W201 is in the same place as the W123
