Good afternoon all

after many weekends of procrastination I finally decided to tack my suspension error, which is basically the air tank filling too slowly.

Checked system and have no leaks so I presumed it was the compressor on its way out, So today I dropped it out.

My question is can any one identify this compressor, its clearly been replaced before as the car is a 2013 and the compressor was checked by Billy in 2018

Clearly not genuine but has lasted up to 7 years, suggestions for replacement greatly received.

OK so my googling find this to be an Arnott P-2815 Air suspension compressor. £565.00

So must be fairly decent, any one with experience of these can they be serviced to tested for faults?

Thanks

Ok so being the person I am... and a life moto of

If it ain't broke fix it 'til it is........

I started to strip this thing apart, starting with the obvious the drier chamber... well I think I have found the problem, the first filter was damp and running my pick over it actually squeezed to liquid like a sponge. under that the desiccant is soaked.. litterally sticking together with moisture.. this would severely restrict the flow through the chamber and then cause the tank to fill slowly.

I have ordered new filters and desiccant to see if this cure the issue.. ill let you know.

I can report I have resolved the error on the dash,

as no one is interested in this post I won't waste time posting the results and how I did it... and just close the thread.

Thanks for the help all who posted

Good result.

If you can, it'll probably help those who follow if you could update the thread.

I saw someone on Facebook the other day with a similar problem. 2021 P400e Autobiography
