Hi ladyc518,
Welcome to the Jaguar Forums! I have moved your post to your own new thread since the old thread you had posted to was on a different subject.
Regarding your Air Suspension Fault (ASF), there are a couple of easy things to check:
First, with the climate control system and radio both turned off and the driver's window rolled down, start the engine and listen for the air suspension compressor to run. It is mounted inside the front bumper to the left of the radiator. Unless the system is fully pressurized already, the compressor should come on after a short delay - anywhere from a few seconds to 1 minute. It should then run for up to 2 minutes. The compressor runs with a "burbling" or soft "popping" sound. If you don't hear the compressor run, wait a few hours and try again.
If the compressor does not run, you can check Fuse 6 in the Front Power Distribution Fuse Box in the front right corner of the engine bay. It's the 40 Amp fuse for the air suspension compressor. If the fuse is good, you can check for 12V at the socket for the Air Suspension Relay, which is R1 (Relay 1) in the same fuse box. 12V battery power should be available at terminal 3 in the relay socket. Use a meter to check between that terminal and any good ground point - there are two ground studs behind the front right headlamp that are convenient.
The relays are known to fail, but there are also circumstances in which the Air Suspension Control Module (ASM) will not trigger the relay to power the compressor due to a fault somewhere in the system.
Let us know if the compressor runs, and if not if the fuse is good and 12V is present on terminal 3 of the relay socket, and we'll go from there.
Also, since we're a friendly group, please visit the New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum and post an introduction so we can learn something about you and your Jaguar and give you a proper welcome.
Cheers,
Don
