4.8is Air Suspension woes

[hamza]

Hi All,

new member here after having recently acquired a 4.8is from my dad. Well technically it was me who found it for him about five years ago but as he no longer wanted it I've decided to buy it from him.

I seem to have a seemingly common problem with mine though but with a slight twist. The suspension on the front driver side will sometime (not always) collapse when parked up. For example it was collapsed both Saturday and Sunday morning but is completely fine right now. When it holds, it seems to hold fine for a long time too, over a week or so.

This is frustrating as I gave it to the garage to repair but of course in the whole week it was with them it remained completely fine so they were not able to find the fault. They did drive it during this time too.

I've read all the threads about air suspension but I haven't managed to come to a clear conclusion on what should be done.

I don't want to end up damaging the compressor if there's a leak that's causing it to run constantly and I'd quite like the car to be reliable as it will get used for long (1month+) euro trips and wouldn't want to be getting it repaired whilst on holiday.

Any advice from the many sources of wisdom on here? Or recommendations of a garage in NW London?

Thanks in advance!
