Life after 110k miles. What should i check?
 

Car did pretty well until now. Wife drives it so I didn't pay much attention, just replaced oil and brakes.

Repairs done to date:

1. AC clutch coil failing (replaced coil only - didn't open AC system) $30
2. DISA flap failed (broke apart)
3. Intake boot cracked
4. Alternator failed at 105k
5. Voltage regulator (HVAC) at 95k
6. CV boots ~50k
7. control arm bushings (large ones) around 50k
8. Oil separator (tried to fix oil use)

Now I decided to do maintenance on it to get maybe another 100k out of car. Oil was leaking pretty bad, looked like oil pan. Ended up replacing filter housing gasket.

Also, replaced valve cover gasket, spark plugs and did VANOS maintenance(o-rings + rattle kit)


What else should I refresh? How is radiator, cooling? Is water pump need to be done at 110k?

What else engine-wise?

I see that suspension needs work and CV boot torn on one side again. Is there any common failure items in suspension on X5s?

I'm looking for 1 big "do it" list so it can be OK for another 5 years..

The cooling systems are always a weak link on BMWs. At the very least watch your water temp very closely as the water pump or radiator could fail at any moment.

Wouldn't doubt your suspension could use some work too.

I assume your fluids have been gone through? Cheap maintenance.

Do you have the V8 or I6?

This is I6 M54

Seprentine belts, all the pulleys. Many E39 owners do cooling system overhaul as a preventative maintenance. That would include radiator, expansion tank,, upper and lower hoses, thermostat, water pump, fan and fan clutch. That might be overkill, but you wouldn't have to worry about them for another 100K mi.
