New member - 4.8is Le Mans

[4.8iS Le Mans_NZ]

Hi All,
Thought I'd better introduce myself, and my latest acquisition - a 2004 RHD 4.8is, in Le Mans blue with Creambeige leather.
This was the 501st RHD built, rolling out of Spartanburg on August 26, 2004, and delivered to its first owner here in NZ in October of that year.
I'm the fourth owner and the car has now covered 166,000 kms (103k miles) from new.
The previous owner replaced the original wheels with the later E70 M-design (which I actually prefer) and a full set of brand new Toyo Proxes.
It's my first foray into SAV territory - all of my prior BMW's have been sedans, coupes or touring wagons.
This X5 has a good service history, both with BMW main dealers and reputable specialist workshops, but it does have a few issues:
- Panorama sunroof rear panel stuck and in need of the DIY repair, which I'm planning to do myself.
- Transmission surging in low gears and slow to engage reverse - suspect low fluid level, so will try the fluid and filter change.
- Blue smoke after extended idle, which has only become evident after changing the oil last week. New oil was Castrol Edge 5W-30, so I may try changing to 5W-40 high mileage Mobil 1 and see if the smoke screen clears.
- Headlamps need polishing and re-coating.
- All paintwork and glass needs a professional cut & polish.
- Leather requires deep clean and restoration in some areas (drivers bolster, etc).
I'll include a couple of pictures - apologies for the poor quality images, but haven't had time yet to get some decent shots.
I'm looking forward to the 4.8is experience and also (hopefully with a little help from this great community) getting the car fully sorted again.
Cheers.
