Need more info ?? Guessing it’s the pressure relief valve on the side of the compressor , what’s the car doing???

Just comes up sometimes on dash showing the sign of suspension fault riding ok replacement compressor & valve block changed 4 mths ago, plug in icarsoft unit comes up pressure sensor, have cleared fault and waiting for fault to show again, if and when it does i will give more information, could be old fault still left on system, Thanks for your prompt reply.

Just plugged in icarsoft unit has suspension fault came up again, its telling me (Recovery time during filling central reservoir is to long) would this be the pressure sensor ?

That sounds like the compressor has either a leak or is getting worn out!! Can you do a fill time test on that bit of kit??

I will run it down to a local MB independent guy , he has a 'Star' reader, new pump was fitted in june ! maybe faulty unit.
