Good morning folks. I have an XJR 2004 replaced all 4 Arnott air shocks , car levels in am & rides well but air suspension fault remains … way to reset ?

replaced the fuel injector ignition new plugs … mpg in single digits , was previously 23 just had injector flush and have throttle body codes … any advice ?

Could I be losing my ECM, if so where find one ?
thank you 🙏

 

Hmmm......I would try a hard reset by disconnecting the negative side of the battery, and after some 10 minutes, reconnect the negative..

 

If after the battery cable reset (which is not quite described correctly... my understanding of the process is to remove the negative, then the positive, touch them together momentarily, then reconnect the positive, then reconnect the negative) you still get codes, there's simply no way to know anything, or even hazard a guess, without knowing what codes are thrown by the air suspension module when the error comes up on the dash. You need a code reader.

 

Ask Arnott. They make more than one type of conversion system.

Unless your Arnott's actually HAVE the damper firmness control valve, each ECATS solenoid needs to be "cheated".
Did your Arnott rig include the gadget to do that?
Should be covered in their docs or one or more of their You Tube instructional vdeos.

"Injector flush" how, with what, and whyso, if NEW injectors were just fitted?

Presently working through some odd behaviour, only one code (MAF sensor) so I just replaced with a new Delphi-branded one. No Joy. Same codes!!!

My suspicion is a vacuum leak. More when I nail it down. Your one might have the same?
