I am having suspension problems.

Car: Audi, A6 Allroad, 2001     -    Back to Fix-It    -    Audi Repair Manuals

Q.Hi, i have a 2001 allroad, and i am having suspension problems. If i park in the 2 highest settings the car will sit fine. When driving along it is mostly fine but when in the lowest 2 settings it drops and the warning light comes on the dash. When parked in the lowest 2 settings sometimes the car will drop on one side, and a hissing noise can be heard, is this a leaking air bag or a dodgy valve/sensor.

I already checked/done: The problem started after i jacked it up but did not put it in jack up mode, so thought perhaps it just needs reset.

Answer If you have already reseted then go ahead and look for a leak in one of the airbags this problem is very normal on allroads the airbags will leak due to a pincht or just because of the age of the car. So I will sugest to check for a leak and go ahead and replace the airbag, the reason why it will not leak on all the levels is because on each level has a seal that mantains the air..

Addition Is it easy to remove the air bag and blow it up with a compressor to check for a leak. If i need to replace it do i need to purchase anything else other than the air spring.

Answer When you replace it you must get the airbag repair kit it contains all you need for this repair. There is one thing! After replacing the air bag you must set the basic settying for the system and you will need a scan tool to do this. To remove it is not that hard all you have to do is get the three bolts on the top and the bolt at the bottom and it will come out as a complete unit with the control arms. Then you can replace it.
