Hi guys, can anyone tell me the most likely cause of this is:

Over night, sometimes and not all the time the left rear of the car is very low, sometimes the left front as well. Since it does not happen all the time I thought it may not be a leak but something else...


I have replaced the fronts with arnotts and recently rebuilt the pump. The rear airbags are the originals and the car has done 200,000 miles!!!

Leave the car at night when the air springs system is off. Just press on the two buttons Lifting and download for 5 seconds and then turn off the ignition switch. In the morning you will see which air spring is leaking.

they only tend to leak when the car is at level 1, would this explain the sometimes sinking the sometimes not?

Thanks bagpipingandy I didn't realise they tend to leak more in the lower position. This is indeed the case and I have ordered a new(ish) rear airbag. It looks like the rears are easier to install then the fronts, but any tips?

(I got one of your rebuild kits for the compressor, getting the thing out was a challenge, but the kit worked well and the compressor still is OK!)

Yes they only leak due to the bag being perrished which when positioned at level 1 the cracks are at the bottom of the bag where it folds and opens the cracks, nuit lift to level 4 the cracks move upwards with the lifting motion and now are on the straight section and close,

i recommend trying soapy water at level 1 to confirm before buying parts
