I was struggling to work out how to change a headlamp bulb in the 08 Passat I used to drive. Eventually gave up trying to work it out myself and looked in the handbook. Guess what "This is a main dealer operation" is all it had to say. Sod that, four screws and a couple of clips later part of the air intake was out giving easy access.
On a similar note I recently needed a headlamp for the Land Rover, standard
7 inch job. Euro parts, once they located one wanted £84!!!!! Remember this headlamp was virtually standard across many cars for donkeys years either with or without side-light holes.Back home, online, genuine LR part £17.80 including delivery.
These modern motor factors can't find anything without chassis numbers and my self built Lightweigh Land Rover/ Range Rover hybrid is becoming a problem finding the most simple parts. Most of what I want is on the shelf but, like the headlamp, they just cant find it because they haven't a clue. What year is it? they say. Well most of the body is 74, chassis is 72, engine 84ish, suspension mostly late 80s, brakes all early 90s with loads of parts new when I built it in 94!
