Can you raise the height manually using the buttons in the car?

No.. it dosnt work..
I found the fuse for the hydraulic pump. I put a new fuse and the car raised at the lowest level.
It can maybe be that the pump is problem?

It is possible that your pump has become contaminated with oil and is causing excessive current to be drawn.

This happened to me and I've got details in these threads here:

Sorry, I misread your post. I recall reading somewhere that there is a large transistor that activated the pump motor (located on the motor itself). If you are lucky then this could be the problem rather than the entire pump.

Shouldnt it be a relay that activates the pump. But it should work manually to raise it up without the relay but can be that they use the same relay for manually and automatic raising
Hmm very strange

Yes from what I remember it is a solid state relay (transistor) that activates the pump. It is signalled from either the BHI or BSI as far as I am aware.

On the pump you can identify it as it has one thick wire and one thin wire, these are the power and signal wires respectively.

Presumably the LDS level was checked? , a leak in the system will bring up the speed warning. Happened to me when the steering rack was on the way out and started leaking. And I was 300 miles from home .....

LHS? Surely you mean LDS (and I am NOT calling you Shirley!)?
