I cant see coils failing the mot, people have been doing it to D2 for years?
As for headlamps you cannot adjust them in the cabin anyway if they are HID, the air suspsenion does the adjusting, which is mad as some of the posher headlamps are adaptive, and can turn corners adjust up and down, yet the driver has no influence on what they do.
The EPB is just fine if people service it, which just means strip/clean and grease, but people ignore it, then they bitch about it!
I remember reading several times on the D3 forum that poeple reckoned the 06 models were the best cars at the time.
Many thanks for your useful post. I was sort of coming around to thinking that the O6 are probably the best. I would not remove anything in it as many one here think until perhaps it failed and then think about my options. I would even leave the EGR valves until they failed and then blank off.
