On a recent mot it was stated that both my headlights were aimed too low, I assumed an easy fix using the up down adjuster on the light unit.
I did a vcds scan on the 55-xenon range and I got this fault.
1 fault found
00776 - Level control system sensor, left front (G78)
31-00 open or short to ground
Am I correct in assuming I have to replace the level sensor?
I'm also getting the error No Response From Controller. For a lot of the things I try to scan. Some scan fine others for e.g. 09-central elec won't scan, just tries 4 times then gives the error :?
No they ain't badly low, I hate having things not working :x. So just adjust them up manually a little cross fingers it's ok for mot.
The tester did say if I fixed the brakes and wishbone bush he would adjust the lights for me for free, if it was just a 2 min job, which I assume it is if it's just fiddling with the up/down screw thing on the headlight unit.
I'm not sure how high they should be, I was going to look how high the beam on my wife's car hits a wall at 20ft, mark it and make mine hit the same bit :?
A faulty sensor explains why they are too low, the headlamps only adjust on start up from a low point upwards to a point dictated by the the attitude of the car, they don't adjust dynamically. Replacing the sensor would probably make them adjust to the correct position but as Roddy posted, if you don't replace the sensor and manually adjust the headlamps, it will probably pass the MOT, depends on how finicky the tester is because if fitted, a levelling system is meant to work.
I did a how to some time ago on this and if you decide to replace the G78, here it is:-
Thanks Steve, the tester did not mention a sensor to me, only said the lights were too low, bear in mind this guy also said I had a fail for my headlight washer jets being inoperable, they work perfectly I think he tested them with the lights off :lol:
I suppose I could phone them and ask them if I adjusted them manually would that be enough.
Perfect example what you can get for £2500. All your thread should be sticky so new comers could see what's happens when you buy cheapest tt on the market.

Have a look at the front wishbone where the sensor attaches, they have an articulating elbow which eventually breaks because of all the road crap that hits them usually they can be cobbeld together with some nuts and bolts and cable ties to make a cheap and cheerful repair, have a. Look at the rear one just to check it's condition whilst you are fiddling.
