Compressor
Fault / Kit Diagnosis
When your garage informs
you need a new compressor in our experience you generally do not ! first thing
you ideally need to do is have your vehicles diagnostic codes read and write
them down (very important insist on it at your garage) and then physically
check which type of compressor you have fitted on your vehicle ( Compare
Pictures in any of our related listings together with diagnostic code description
)
