Pretty sure the thermostat isn't working properly on my X5 as it only gets near the halfway point on the temp guage when its been idling for a while and then goes back down again.

Few questions:

Do I need to (or is it advisable to change the EGR thermostat too?

Do people generally replace the housing too or just the thermostat itself? (Just did the thermostat itself on my E46 M3 although that did have a metal housing)

Can anyone recommend a brand? Don't want to pay BMW's usual mark up on someone else's part.

Car is a 2005 3.0d BTW.

BEHR is a great make and the e53 thermo only comes as a complete unit...stat and housing combined, up to you if you want to change the EGR stat....you may aswell then you know theyre both done...dont buy cheapo or you'll be changing them again...

Cool. I've seen both behr ones on ebay as a pair but come from Germany so I might not get until new year and ideally I want to do it over the Xmas break. Will have another look. Cheers

Easy job - drop the coolant, remove EGR pipework and MAF-to-turbo pipework and you can access the thermostat housing without even removing the fan. You'll need an e-torx socket set...

Have you got the EGR stat my 2002 car hasn't got that one just the main stat.
Easy job anyway.
