I just bought a 190E (1988 Model) and I notice the fuel meter is moving up and down after cornering. It can move from 1/2 tank to empty then slowly back to 1/2 tank. Is this normal?
The ABS warning is on but the break is still working. I am not sure how to test the ABS, but what usually trigger the ABS warning light? I hope I don;t have to replace it totally. Please help me...Thanks.

When the ABS light is on the system is inoperational. That is the Anti-lock feature of the brakes. Usually this is caused by faulty sensor(s).

Does the light ever go out? If it doesn't go out then there's a voltage supply problem, if the light goes out & comes on w/driving then at least one of the "sensors" are bad.

No, the light never go off while driving.

Where are those sensors located ?

I had my ABS light which would go on sometimes. If the light goes on, then drive to your nearest MB shop and ask them to connect their computer to your car so they can see which sensor is bad.

They didn't told me that the first time I left my car to them, they "just" changed the batteri because they thought it was a low voltage supply problem... of course not :-(

If they had told me that in the first time I wouldn't had to leave my car to them again. This time they located the problem to the left wire harness going to the sencor=which was replace and they also greased the sencor.

Good Luck / Patrik from Sweden

A votltage problem could be the overvoltage relay being faulty or the supply voltage to the ABS being too low. Again though have the sensors tested. It is a simple test with a scope.

FYI, I have resolved the fuel meter problem,
it was due to the fuel tank float which
cause some contact problem. For ABS, I will
get the dealer to check further.
Thanks

I got the ABS problem resolved, it was due
to a blow 10A fues on the ABS relay.
Thanks

There is no ABS relay on this car...The fuse is located inside of the Overvoltage protection relay we discussed. Thanks for letting us know what was wrong.
