    If I'm not mistaken that's just the load sensor for the xenon auto levelling headlights isn't it?

    9 times out of 10 the issue will be a snapped earth strap forge haldex unit. You'll need to get right underneath and have a look to the right of the haldex unit.

    +1 xenon leveller... that will fail the new MOT's

    Earthstrap, wiring plug or precharge pumps are generally the faults related to Haldex systems
