I have a problem with the headlamp warning light coming on my dash. It goes off momentarily after start up but comes back on a few seconds later. The headlamps appear to be level. I,ve removed both offside wheels to access the front and rear level sensors and given them a good spray with WD40 and removed the plugs and sprayed them also. The front plug had some corrosion in it so if I had to guess, i,d say that is where my problem lies. Does anyone in the Wirral area have a spare that i could try or buy? Or, will this fault show up as a code when the car is plugged into a diagnostic tool? Anyone know where I can get a new one without being fleeced by my local dealer? Could I get a pattern part? Thanks in advance for any help offered.
