Wonder what happened? Car wash accident? It would have been nice to see it. :thumbup:
A few X5s are around Austin. At least one other in my neighborhood.

:bustingup Where have I seen that sight before?.?

I was getting an ISCV fault fairly regularly and when it through that fault is seemed to cause others and it would go into safe mode. I replaced it quite awhile ago, but about 6 months ago it started to throw the code. I could usually just shut the car off and restart and it reset itself.

The other codes I have also seen and IIRC it was when my alternator was getting ready to die.

I miss tennis. And would never, ummm, sandbag. ;)

E53 wise... just been tinkering with the audio install. Need to take it in for annual state inspection. Maybe I'll take it to the dealership so the techs can enjoy. Needs front tires though... mine are 7 years old. Still plenty of tread, but wonder if there is a maximum date code for safety inspection?

Finally bit me
 

So, this was/is a fun project in my driveway today....
It finally happened to me. In the middle of an intersection, step on gas, just that dreaded "whirring" sound.....flat bed, confirm, part ordered on eBay. No warning, no odd sounds, just bang! If you know, you know....

This was on the 4.6iS right? With the LWX500 TC?

I don't know.

Enlighten me...

I'm not familiar with this one. Were you towing a Sherman tank or something?!

No, no, no! This is a very common problem on 2001-2004 E53. The front driveshaft splines where they go into the transfer case are not inserted very far and I think there must have been a hardening issue. This is so common, there are numerous suppliers of a replacement spline that is 1" longer. This is why I cut off the factory one, and the new one(on it's way) will slide in the shaft, and I will weld it together. As I posted, no warning, no noise, went to leave a stop and loud bang, no movement, lot's of whirring noise. Lot's of people think they blow their transfer case. Just the splines stripping. Beware!!!
And yes, this is on my latest 03 4.6. They are all the same.

Full disclosure: I have never had this problem on my 2003 X5. And therefore I have not done my research.



That being said, the picture you just posted doesn't look like it was caused by any spline problem to me. It looks like a bad weld joint. Unless I'm missing something and the parts in the picture are the replacement parts?
