Typical. Only three weeks to go before the delivery of the new car, the intermittent problem with the occasional lighting of the xenon warning lamp on the dash has become permanent. In another cruel twist of fate, the MOT is due which means a failure

As I suspected, I
think I have narrowed it down to the adjustment motor in the drivers side headlamp. It makes a juddering noise as it attempts to adjust the light. I really don't want to source another lamp at around 200+ euros, so I was wondering whether anyone had successfully stripped the lamp and repaired the motor? I know they aren't available as replacement items. I'm happy to invest a couple of hours time but I don't really want to spend any money. And I don't even want to start the job unless I'm likely to have some success.
