She has a clogged catalytic convertor and at the cost of a replacement, it just doesn't seem to be a logical decision to spend the money on it.

Unless someone can give me a suggestion on a way to keep her alive another year, I think I'm just going to part out some of the nice parts on it and donate the car.

If anyone has any interest in any of the features or hard to find parts on this build, PM me.

This is a question for anyone who has dealt with seat occupancy airbag light. Out of nowhere, on my 2006 4.8is, my airbag light illuminated. After a feeble attempt to read and clear with my Autel scanner, the error persisted (shown in thread title) my question is if anyone was successful just replacing the sensor unit (currently on clearance on FCP for $87.00)…versus the whole sensor mat for $200-300? I never knew of the sensor unit, itself…I had only heard of sensor mat issues. Anyways, is there a way to test for one versus the other OR would I have a good chance of success with resolving only with the sensor unit? Any guidance??? Thanks!!!

Is my first post here, after watching the forum and finding a lot of useful info.

I have a 2004 4.8is, RHD, and I plan to convert it to LHD.
I have a parts car, a nfl, 2001 4.4i.

Is the steering rack compatible? On some sites that sell reconditioned units they say is compatible with fl/nfl but realoem seems to disagree.

From what I can find the subframe seems to be the same, so I would assume there are same mounting points.

Did anyone changed the rack from fl to nfl or other way around?

nfl also have servotronic, so I will retrofit that as well (found a nice post about it, seems easy enough to go for it)

I think this was an upgrade. Is this thing easily removable? Does the car look okay it it's removed or does it then look like something is missing. ]]> X5 (E53) Forum Meestahbig https://xoutpost.com/bmw-sav-forums/x5-e53-forum/116664-does-anyone-know-pull-out-trunk-bed-option-removable.html https://xoutpost.com/bmw-sav-forums/x5-e53-forum/116663-e53-3-0-6-speed-manual-swap-here-transmission-transfer-case.html Mon, 24 Aug 2026 12:00:48 GMT I am not the seller.

Hi everyone, I’m troubleshooting the electric cooling fan on my 2007 BMW X5 E70 3.0si (N52, built 09/2007).

* Cooling fan does not run.
* I replaced the fan with another known-good fan, but it still does not run.
* I checked the K9137 cooling fan relay.
* F171 100A fuse has been checked and appears good.
* Battery voltage is about 12V with engine off.
* With the K9137 relay removed and the engine running, the B+ input terminal of the relay has only ~2.3V
* The small 2-wire control connector at the relay measures around 4.4V.

My main question is:

Why is the K9137 relay B+ input only ~2.3V when the engine is running, instead of ~12–14V? Where does the B+ supply to K9137 come from, and are there any intermediate connectors, fuses, or power-distribution points between F171 and K9137 on this E70?

Any advice on the correct wiring/power path and recommended tests would be greatly appreciated.

I want to buy another. I'm really looking just at the 3.0i but see a nice clean v8. How much harder is it to work on. I'm not worried about the body, that I know, like the doors and the lights and interior, that's the same and I can do all that nigly little shit, but what about the engine peripheral stuff. Is it much harder? Coolant tank, belts, cam sensors, etc. I guess it has twice as many in some cases. I also recall reading something once about the valves and black smoke. Any detailed info would be nice.

Should I just stick with the 3.0. we know these are rock solid engines and transmissions.
