Is it the fins that are metal, if so, thats the better one as the plastic ones are known to snap.

BMW's are a nightmare to bleed!!

Your right there must done the bleed about 5 times , I thought I sorted it before as when I put the water pump back in it got hot and stayed hot Evan when driving until I came to a junction and stopped it became cold again , and back to the water pump the whole end is metal Evan the fins

      Resonator assembly clip

      I am new to site and just bought a used 2017 330i xdrive. I was going through the engine trying to get to know it a little and I found a resonator assembly clip sitting near the resonator but connected to nothing so I’m trying to figure out where it goes? There is already one connected to the intake tubes so I can’t figure out where it went or where it goes? 13-71-8-637-816 - Resonator Assembly Clip 2017-2023 BMW | Braman BMW & MINI Parts.pdf

      04 525d

      Hi all, I have an 04 525d that I’m looking to get rid of. It has been well used and served me well but unfortunately I’m not willing to spend any more on it due to the age. It has 185,000 on the clock and recently failed it’s MOT due to perished ball joints. my question is, is it worth trying to mess about and sell it or just scrap it? any advice would be greatly appreciated. cheers

      Coolant leak

      Morning Kev Welcome to the Forum I am aware that the plastic return pipe (Header Tank to Rad) on the E53 became very brittle and was easily damaged. I replaced mine with 10mm Copper Tube after a long wait for replacement. But I was not aware, or haven't heard of X3 issues here in the UK I guess that you will need more from US based owners Dave
