Hi

Need some advice.

Have problem with un even back suspension.
When driving over speedbumbs the suspension is hard on the left side and soft on right.

Looked i diagnostic and the voltage on the left height sensor is way lower then the other sensors..

And the car is even in height.

Do I have a faulty sensor or could ther be a another fault that causes the voltage to dropp?

Many thanks in advance.
Anders

Hi Anders, Basically there are 3 possibilities:

- Bad electrical connection of the sensor > clean the connector (male and female parts) with contact spray.

- Mechanical: the connecting rod on the sensor came loose*

- Sensor defective.

*Yet another possibility: the sensor bracket was bent, but that can really only happen, deliberately or inadvertently, when work has been done on the rear left suspension just before the problem became apparent.

Hi arconell3

Yes, then it´s most likely to be a sensor fault.

Have new one ,will replace this weekend..
