(2004 XJ sedan w/120K miles)

I, too, am now seeing occasional and temporary MC displays of Air Suspension Failure, accompanied by a small yellow light in speedometer cluster. These appear only in cold weather, and the car doesn't seem to have any ride height or other related suspension problems. (I have read the Forum entries for this subject...thanks, guys.)

Question: Has anyonereplaced relay #4 and successfully resolved acondition like mine? Is cold weather a contributing problem to compressor or relay failures?

Thanks,

its more likely not a relay problem, but a compressor problem, especially with cold weather,. Its turns on the amber light and display when the module see's that the reservoir pressure doesnt reach the required psi reading in the spec'd time..
