ML are expensive, but... they will tell you everything that needs to be done.
MJF - I like Mark but I'm not sure I would return the BT there, although I do know he has great BT references from a few guys here and did a great job on Rojer's engine. It's personal preference time!
I run R134a - had it converted by ML and it seems to work ok.
I didn't have to convert the fog lights - and it's passed several MOT's so I assume you just leave them alone.
Headlights - remove the front grill and the metal trim below the lights (a tricky pig of a job made easier if you remove the bumper which is simplicity itself). Then remove 4 philips screws each side, remove the headlamp assembly, loosen 2 little screws on the dip beam and twist through 45 degrees - easy.
Side Repeaters - buy the kit from the dealer. Cover the wing in masking tape, stick the template on the wing and carefully drill and file until you have a neat rectangular hole - I did mine and it's not difficult if you take plenty of care with the drill!
Turbo care - warm the engine gently, 3000 RPM + no boost until 80 degrees and for the cool-down, drive it gently for the last few miles and then I let it idle for about a minute before switching off. Providing the electric water pump kicks in when you switch off, water will pass through the turbos and prevent damage caused by heat soak. Oil Pressures - when hot, I have 4.5 to 5 bar during normal running and 1.8 bar at idle.
Diff temp - I use this to tell me when the diff is up to temp so that I don't abuse it until the oil is warm/hot. Normal running for me is 40 to 60 degrees and the coldest it measures is 21 degrees I think.
Cigar Lighter - check the fuses and at worst case this is just a 12v feed which you ought to be able to fix yourself - does the rear cigar lighter work?
Radio - check the amp and crossover box in the boot on the left hand side behind the trim. If the stereo is standard then this box provides the sound - the radio itself is just a pre-amp I think.
