self levellers
Just failed the mot due to several things but the real puzzle i would like help with is the rear self levelling sensor. The tester states its missing and technically he is right. Sensor is screwed to the sub frame but its not connected to anything due to the double ended pivot arm being absent, however there is no bracket on any part of the suspension for it to connect to. In addition i would say its not been connected for years, its rusted/ corroded into a blob of plastic/metal, so can the levelling sensor at the front do the job on its own??? Opinions on how to proceed appreciated.

If you place a heavy load at the rear of the vehicle it will have only a small effect on the front suspension, but rather more on the rear!
So no, you need both. |

If you want to try and 'cheat', remove the rear mechanism bits that still remain, tape up the sensor electical link out of sight and go somewhere else for your MOT (ensuring the front sensor does still operate properly). |

thank you chaps, I have gone down the replacement route, the rear sensor was shot and had a bmw part no so thats on its way, and the missing link is ordered from a supplier of adjustable connecting rods that have excellent reviews. I will fabricate a new bracket for the upper arm fixing point , so will post how I get on.

I know that I need to replace the rear level sensor on mine as it appears to be seized and the plastic arm is all twisted, it doesn't seem to have affected the levelling though.
Funnily enough, put my car in for service/MOT yesterday and they found the front levelling sensor arm had become disconnected so reconnected that before testing. Haven't done a lot of night driving recently to have noticed that the beams would probably have been on the default setting, which is dipped right down - unless it had become disconnected in the mean time. |

The levelling is done by the special dampers, the sensors are required to set the headlight assemblies to the correct functional positions. |
