All of us with the 4.8i should be asking BMW that question, seems they have shown us several examples of how it can be done...
The Germans are GREAT at Engineering, but not so much on design for mass production.

That said, LOVE my 4.8!

Looked around a bit with impending snowmageddon 2017. No weep hole leaks!!
Upper radiator hose is wet.
Part ordered.
Let's hope a few hoses solves it......

Uh oh. Started her up and leaks stop. But there is also a rear engine leak.
Strangest thing is it only happens when sitting and not running and warmed up. Sounds like a worn out oring somewhere! Hope it's not in the valley!!

I have leaks as well only leaks when sitting, also very strong wheel sound from the front Passenger wheel side. ALSO when I brake hard or stand still on an slope upward I get a burning oil smell.

Took it to a local Indy shop and discovered
Valley Pan leaking oil
The passenger and driver front wheel hubs shot, the drivers side almost seized
Both Valve covers are leaking oil
Upper timing cover gaskets leaking

The engine looks like new would never know all this was all happening

My local Indy shop said will take 3 days pulling engine will need to take 3/4 of the engine apart These guys are certified BMW ASE mechanic

They quoted me $2260 for the entire job I SAID DO IT........

Getting it back on Monday March 20th they had it from March 15th.

Keep you posted

Driving the car daily. No leaks after upper and lower radiator hose change!!!

But now I have the mysterious disappearing coolant? Low coolant in reservoir.

Ground is not wet.

But where is the coolant going?

I'm getting ready to tear into it and do the Valley pan and tube.

Are you sure that isn't just the result of the coolant system purging the last bits of air from changing the hoses?

My money is on the valley pan gasket.

This was my thought. I haven't done any coolant work on the X5 yet, but I know on my E36 it's pretty common to have to top off a couple times even after bleeding the system.

had to fill about 1/4 gallon. 1st time. My level sensor not working from PO. I think he knew and traded it due to the dealer quote of valley pan.

But I'm going in expecting this. So, I'm ok with it.

We'll see. If I need to add a second time, the coolant pipe and valley pan are coming out
