Mein Auto:
2002 330xi with 168k-recommend maintenance?

I just bought a 2002 330xi with 168k with no maintenance records what would be the recommend maintenance?
What I have done:
1. Changed oil and filter.
2. Changed air filter.
3. Changed cabin filter.
4. Preformed coolant pressure test. Check good and looks like new hoses and belts have been replaced.
5. Checked water pump-good flow.

What other PM items should be looked at or changed.
1. Drive train items
2. Suspension items.
3. Other items.

Thanks in advance for your input.

If you dont have records of when the coolant expansion tank was replaced, that is job 1. Anything more than 70k miles on the cooling system is a crap shoot and if it goes you only have a short time to shut down the engine before overheats and is toast. My tank went right on cue at 70 but YMMV.

And read the Wiki on this site.

At 168,000 miles I'd either replace the DISA unit (part: around $200) or better yet, repair it with the German Auto Solutions DISA repair kit (around $90 and it's actually an improvement. There are recent threads on this in this forum.) Replace this every 120,000 miles or so, though the repair kit is supposed to last longer than that.
