Sorry my ignorance, could you explain me how to use my Hawkeye to tell the cars' electronic systems that it is now on coil springs. I mean I went to chassis, then air suspension, then ...?

Hi Javier, I can't remember with Hawkeye as it's a while since I've used it but what you need to find is the 'Programming' section - it's under either the chassis or BCU menus - run through the programming section until you come to "Air yes/no; select No then run through the rest of that section until you come to the end then it says something like "Confirm market changes yes/no - you select Yes and that confirms the change to coils; so you won't get any more error messages.

Then go to read codes and clear codes, then you are done!

OK, very usefull.domeone know about HAWKEYE (ther´s no user manual?), what does the 4167 "event ON-Duration compressor" fault means ?

The air compressor is trying to work all the time, which is not normal - once you have your coils on and re-programmed, clear the codes and that will end the error messages.

If you change from air to springs DO NOT FORGET TO INFORM YOUR Insurance company many do like it
