Air susp inactive again

MariusRR · Nov 3, 2014

Hi,

I have had troubles with my air suspension since I bought the car.

It sits at normal ride height, but is inactive. I have tried to delete the fault codes (which reads something like to high temp out of compressor/sensor).

After deleting the fault codes everything worked perfectly. Drove 300 km without trouble. Next day the message was back.

I tried changing the piston with the kit from BagpipingAndy. Deleting fault codes again. This time it worked for 3-4 days. Then back at air. susp inactive.

The compressor was changed to a brand new one in 2009 and havent been driven more than 30.000 km.

Any tricks up your sleeves, masterminds?

Checked the air bags for leaks ???

Maybe temp sensor on pump itself???

Marius,

Can you get the exact fault code description?

Usually overheat means worn piston or a leak in the system causing the pump to work overtime which results in an overheat of the pump

Marius,

I posted a link in the how it's outlining how to check your pump output which may assist with diagnosis...

If it sits at normal height but is inactive, I take it that the suspension lock button isn't pushed to lock ? Sorry just seen that it is an L322 but I'm assuming that it can be locked for towing

+1 L322 automatically locks when the trailer electrics are connected, and is lockable by the push button on the selector/ changer.
If the Pump is getting hot I'll go with the others and advise that you get the soapy water out and have a good look around.
Lastly is this the only message that comes up - ours is sending out a few due to lack of use , which disappear once the voltage in the battery goes up.

The compressor was water damaged. My mechanic took it out and put in a refurbished one for a small sum. Now it works perfect again.

Now sort the water leak out before it does it again!!!

Thought the swimming pool was an optional extra.

Seems to be a standard feature on L322.
