My car is just run-in at 104k. Not bad for a teenager.
I’m about to change the Gearbox oil, supposedly “Sealed for life” but life in BMW manuals means 100k. I’m beginning to feel Gear changes, which should not happen in a 7 unless I use kick down or REALLY FAST kick down. Problem is, it needs changing twice within 100 miles, to ensure that most of the residues have come out of the torque converter. You can never get all the old Gearbox oil out, unless I put it on the Fuselage turnover fixture at Warton LoL. The GB takes 10 litres at £15 per litre, so it’s a £300 job!
I change lump oil and oil filter every 10k (Should be more freq. but money is tight). I run a magnet through my old oil, see what’s in it. Touchwood, nothing “Feelable” yet. As my Sparky plugs are only £2.30 each (OK, probably now £4.00 each after the 3% rise in VAT in Rip Off Britain) I change all 8 twice a year. It takes a few hours as the rear ones are back-breakingly hard to reach. I’m expecting to get minimum 250k miles from her, the lump will do it, it’s the electrics that need nursing. It’s built after the end of real solder (With lead in it) so the old “Dry joints” problem is possible. I still have a few meters of real solder (1mm diam) left and a meter of real plumbers solder rods. Remember when lead pipes were mended by that massive swolen bit LoL.
By the way, dry joints can often be overcome by a quick waft of the circuit board with a heat gun. Obviously not too close! I believe some Wii’s are already being repaired in this way, anybody confirm?
