Hi,

Having problems with my air suspension. I had the orange and green flashing lights. Checked the codes and had J403 relay open circuit.
I have found the relay eventually and swapped it out. Checked the fuse all ok.
Still the same code. I have checked the output to the compressor and the wiring down to it and it is all ok.
Checking the voltage on the relay input it is about 0.5V which I suspect is too low to fire the relay.

Where can i find the control unit to swing through to the relay. There is a diagram on a parts site that the control unit is on the bulkhead (the C5 one is in the boot but in the C6 version it moved), I have checked under the steering wheel but there doesn't seem to be there. I cannot see it around the brake servo at all- unless it is in the central air box.

Could anoyon let me know where it is or has a picture?

Many thanks
 
It looks like its probably behind the glove box. I’m going off a parts catalogue and it shows a left hand drive with the unit behind the glove box, so would assume that it’s the same with a right hand drive, behind the glove box.
