Customer Question

We have a 2003 Jaguar XJ8 in our shop. Vin#SAJEA71C84SG07444. Customer said he was driving down the road and the front of the car dropped and both front struts deflated. Towed the car to our shop. Scanned The air ride control module. No codes We can't get the air compressor to come on to check for leaks. We jumped across the relay and the compressor works. Any ideas what we can do here?

Right now is the front down? Is the vehicle too low warning on?

Can you communicate with the module at all? I know you said there were no codes but can you read any sensors?
Customer: replied 1 year ago.
We can communicate with the module. But our scanner is limited to amount of data. Here is another twist. We started the car and moved it alittle ways and the compressor can on but the front end didn't raise and the compressor shut off after about a minute.
Expert:  Richard replied 1 year ago.

OK we either have a weak compressor or a leak. Listen for any air noise from the front shocks. We can also loosen the air line and with an air blower with a rubber tip we can carefully inflate the air struts to see if there is a leak. Let me know.
