Having had my 2012 TDV8 in bits during the lockdown to waxoil etc when I put it back on the road today I had an issue with the air suspension. The car is slow to rise and hence had a normal mode only message on dash, this reset when the car was restarted and was okay driving. When I got back moving the car to off road mode and access mode the compressor overheated. it was also slow rising the front. The car remains at height when left so probably haven't got a leak. It might be just a coincidence that the compressor is failing as i put it back on the road.
Looks like I rebuild kit for the Compressor? How do I tell if its a hitachi unit?

Well I decided to take the pump out and have look at it.
My Icarsoft showed the Gallery pressure (which I assume is the pump pressure not res tank pressure) only climbing slowly and didn't get to a high pressure.
The pump look in good condition, no obvious leaks so took off Dessicator and dismantled. The dessicant looked okay but the cotton filter at the pump end showed signs of clogging. it has a metal sheet with small holes in at the pump end and these looked very black. cleaned cotton filter and replaced other way round so hole where on fresh cotton.
Put back together and replaced pump.
Started car and suspension rises quickly, Gallery pressure get to around 1400 kPa before pump stops.
Lets see how is behaves over the next few days
