Firstly hi to you all, and many thanks in advance, I am currently to owner of a lovely x5, absolutely fantastic I really do love it, my issue is the front prop shaft, it has had it's day and all the splines going into the transfer box are worn, I know in America there is an extended spline that can be added to the shaft, there fore my question is does anyone in the uk make, sell these. Many thanks again kevin

I have read about a shaft with an extended spline but they have all been talked about on the US forums. I believe the company is in California

What symptoms are you getting?

No drive what so ever just a really loud grinding rattling noise, removed shaft and you can see the wear

It will probably be the chain in the transfer box that seems to be the culprit if your getting a grinding noise. If you have the transfer box down open it up and have a look.

Grey dog thanks I will strip it tomorrow and have a good look, the splines on the end of the shaft have worn and started to round, splines inside the tbox are very worn also, this part was engineered to fail, the shaft can be inserted at least another inch but bmw choose not too

You are right the design is rubbish, it should have had doughnut at each end with a full length drive sleeve in the Transfer box.

I hope you get it sorted without to much financial pain.

Welcome by the way

I like it

I don't think there are any sellers in the UK. Why not buy from the US ? just google X5 extended front prop shaft. What symptoms are you getting? If it;s vibration it could be the transfer box chain.

Another newbie looking for help....

I bought a 2004 325 ci auto with only 27k on the clock, Happy days. All has been well for the first couple of months until the dreaded cog light came on the other day and sent it into limp mode.

I read all the horror stories until I spotted somewhere that a week battery can cause this?

With this in mind I now notice that the car will send it into this mode when I turn the ignition on in the morning without starting the engine but after a few minutes drive, if I turn the car on and off it clears. I have driven it around a lot recently and there has been no sign of re-occurrence.

The battery shows no real sign of being low as the car fires up a treat, although I do notice the dash board lights illuminate more responsively after a spin up the road from a cold start.

Could the battery be the problem that I have mentioned above? could it be this simple?

cheers,

Gregg

Battery first stop get it checked if its original it will defo be on its last legs
