All everyone , I’ve got these faults on my bmw x5 40d n57 2011

471c - intelligent battery sensor missing 

had it on the car since I’ve had it- 8 weeks 

Also 49A6 communication fault

the car starts fine on cold start but a little lumpy on acceleration until warm 

noticeably now since it’s turned very cold  here like 3 degrees most days

Morning Aaron

If I recall the IBS sensor on your car is part of the Battery Negative lead not sure if it can be repaired or if it's simpler to just fit a new one

You softy 3 deg isn't cold -3 deg is cold - 5 deg very cold 😅

      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
