I have a 2003 E55 that keeps giving me 5260 and 5270 (y54y1 and y54y2) right rear solenoid valve 1 and 2 Open circuit. I changed the shocks between them and the code is still there. Any ideas how to go about it? The car stays at the right height and performs as designed (i can raise it and at 80mph comes down as it should). I did clean the plugs under the right rear fender and the code is still there. No idea what to do, I am thinking to clean the contacts of the N51 module but I am not sure where it is. It seems some are saying the module is in the fusebox in the engine bay and others are saying it is under the passenger carpet (anyone knows where it is with certainty?) so again any suggestions on how to troubleshoot these two codes is highly appreciated! Thanks Bob
