I should be getting mine back today if it road tests ok, they have changed a vanos valve, vanos sensor and they decided to change the camshaft sensor (just in case) as they had the car apart in that area.

Cars back, faults back, DISGUSTED, nothing else to say!

Very sorry this is happening. Very frustrating. I am 19k miles and not a single hiccup or issue (other than self-inflicted). But that is another story.

I got 3 stop lights from my dealership and it failed again.The icu receives and sends information to all of the cars modules, it also had nothing to do with whatever on earth is wrong the entire thing was replaced on my latest pit stop....

Let's here about the "self-inflicted" hiccup?! What happened?

Mine is running smoothly again - seems to be a love/hate relationship!

Cheers,

BMW seem to have produced an engine so complex with so many warning shutdown systems on it that they are incapable of diagnosing and fixing the actual issue. Much as I love the X5 M the most important factors for me are safety and reliability, my car fails on both counts.

Mine is going back in today but they already admit they don't know what to do next if the fault codes are the same (which we expect).

There is no Lemon Law here like you folks in the US have but we do have what's called the Sale of Goods Act, this clearly states that a fault must be rectified in a reasonable time, be a lasting repair or the car must be replaced. BMW are rapidly running out of reasonable time.

Cheers,

Part of it I already posted. Where water from a loose grommet was running into the computer in the rear side compartment. The rest I will be posting soon.

X5 M is still in the garage, BMW now think the vanos is not working fast enough on the nearside bank inlet camshaft, I say think because I am not sure they actually know this but are just presuming this is the only thing it can be.

*If* this is the problem they don't know what is causing it or how to fix it, yet.

BMW and JOY, not two words that should ever be associated.
