Thanks for your input. I checked the the DC Voltage with a meter on either side of the fuses (152 and 182) on top ,so I know the fuses are good
I also checked the relay 'on the bench' and it's functioning too.
Maybe the car needs a reset with a BMW Diagnostics kit as there is still an icon on the dashboard which will not clear?
Hi My rear suspension failed last week and I diagnosed the problem to the a 'sticky' main solenoid ( not the two way block)
I replaced the solenoid and checked it and the compressor before re- fitting to the car.
Guess what/ The compressor doesn't work as there is s no 12v to the compressor
The fuses (152 and 182) are fine and the relay works when tested 'on the bench'?
Any ideas guys?
