'04 525d with 90k on the clock, what would you do to it next?

6 posts in this topic

I picked up a well-priced immaculate 525d and so far have:

 

- Replaced the cracked exhaust manifold with an aftermarket cast iron from x8r

 

- Replaced the Main and EGR thermostats with genuine stats as the temperatures were stuck around 70, now they get up to around 90

 

- Oil change, air filter, brake pads done

 

I've plugged in DIS and everything is mostly fine except for some glowplug errors, as the glowplugs are so cheap should I go ahead and replace all 6? Is it worth doing the controller at the same time?

 

I also plan to blank the swirl flaps.

 

Any other preventative maintenance or improvements you would recommend? I've read something about vac lines? Remap?

 

thanks a lot for your help

If auto do transmission fluid and filter change.

 

Definitely this!

 

Vac lines is a good shout too and not too hard to do on your own if you've got small fingers!

That's right,  vac line problems are on the 535.

There are vac lines to the egr and suchlike but they dont collapse very often. 

 

I would definitely change the glow plug controller if you are changing the glowplugs
