I had a drooping front end suspension issue on one front strut and therefore replaced the front shock . Then the car started dropping on both struts from the front end so i replaced the valve block. Was fine and then the rear end started sagging on both wheels after 2 to 3 days.

So i replaced the rear valve block.

Ran fine for a day and now it gives a permanent error and drives in extended mode.

Even with fuses off it stays upright so

Q1. does it imply that there is now no air leak anywhere.

Q2. How do i release the error. Every time I erase it using the LAUNCH 431, it reappears as a permanent fault.

Any advise is much appreciated.

Also had an intermittent fault on the Main Display . Dealers said it was the AMP and we put a used one and it has worked fine for 6 months. (New one was quoted at USD 3000) . Now the display comes and goes at random. When its not working it simply shows the LR logo. When its working everything works fine. Since it was working today i checked it and the error code B1A04 (Speaker 4 came up as an error) . Is it another AMP issue or could be a loose cable. With all the fibre optics running around you never know where to start
.

 

Extended mode could be exhaust valve on compressor.

 

Those are not complete fault codes. I suspect you either need to update your Launch or try a different scantool. Codes are formatted like: C1A20-64 or C1A18-00

 

Also, and I'm no Tech....but it sounds like a calibration issue (all along) to me. Not sure you even needed to replace the shock.
