Hey, has anyone had this problem?

Sometimes, often recently after engine startup, but after "OK" in the fis system, the ESP and Height Adjustment warning lights come on. Typically a few seconds after i start driving.

They do not blink, they just stay on. If I stop the engine, and restart, they are gone. No sound signal either, and no animations on the fis screen

IŽve had no other issues with the compressor/air suspension, and the car sits level.
What could this be?

HaveŽnt had time to do a vag-com checkup yet, just wanted to hear if anyone else has had this?

Thanks! Joergen

Sounds like compressor or valve block.
After you start up engine, the compressor activates annoyingly for few minuite until the suspension warning lamp lights up?
i had same problem before.
Probably the compressor is getting weak.
The time to go Wabco?

BTW i didn't replace it, but i supplied air tool oil a bit, then problem had fixied.
However supplying air tool oil seems to be strictly prohibited by everyone in this forum.
i have done this more than one year around one time per two month without any problem.
i don't recommend it because my friend got the problem on the valve block by supplying oil.
Thanks.

hi allroad55!

If the compressor kicked in, the level marker in the dash would be blinking, right? The green marker does not blink.

I read something in the manual about warning light in the dash if the car was parked in an unusual angle. I suppose a vag-com check would give me more hints to whatŽs going on.

Hi joenok!

If we push the level up button in the dash, the level marker green led would be always blinking until the car would reach to the higher level.

However even if the compressor was activated to keep the current height level or appropriate air tank pressure, the level marker would NOT always be blinking.
i think this is quite similar situation to the case of the compressore activates shortly during we driving around the street.
But the sometimes the level marker would be blinking when the car could not keep the level or pressure in the tank and obviously the car must be moved up or the level must be controlled.

If you encounter the compressor activateing so frequently,
and sudden lighting up the level control warning during drinving or after starting car, i bet the compressor has shot!
Please never quart air tool oil to the compressor.
But im...

Belows are the codes pulled by vag-com last year before my quarting oil to the compressor.
