BMW is cutting edge... not a Toyoto appliance. Yup you gotta spend money to fix the things that break but to me BMW whole experience is worth it. Sure $10K to fix a coolant leak is CRAZY...

But look the aftermarket responded and came up with a collapsible repair pipe to cut the bill down to around $1500.... THAT WORKS! Get hooked up with a quality reasonable independant BMW repairer and spending money to have a E70 4.8i is WORTH IT

^^ Interesting product.

Wonder how long IT lasts....given the heat cycles that part sees, I'd be concerned with the middle o-ring as it is the sole source of the preload onto the two other seals. Plus there is a split in that shim that jams the front washer into place....

At ~$500 they are making a killing....

Joined the Valley Leak Club...
 

My 2008 4.8i is now a member of this club, and I would have preferred to not join...
She's in the shop having a Valley Leak repaired right on time at 69k miles... $3400.
To make it even better, the Thrust Bushings were cracking, so they are also being replaced... $750.

It's a big hit, no doubt, but I can't piture driving anyting else.
Just love this car way to much... ;)

what are the symptoms to the infamous valley coolant leak? Does it leak internally or run down the motor and on to the ground?

Just a Low Coolant Warning...
 

I had a low coolant warning when starting up for the first time one morning, and again a couple of days later. Took it to my Indie (in Indy) shop to have them top it off. It was 1/2 Gallon low, and the noticed a very small amount of coolant running down the back side of the block.

There was never a puddle or drip under the car, no smell, nothing that pointed to this. The leak is very slow and gets burned off by the heat from the block and headers/exhaust before getting to the bottom of the car to drip...

A system pressure check confirmed it. Now I'm without my X for up to 2 weeks.:confused:

Ok. Thanks for the heads up. This vehicle scares me lol! Too many potential repairs coming up...

I had a 7 before the x5 and no problems. Did you follow the maintenance of changing coolant every two years? This will prevent the dreaded pipe leak. 7 had 150k on it and never had any problems. It was an 02 the first year and a lot of people had issues. Mine was flawless when I traded it in

Oh man. Threads like this make me cringe--especially with a 2007 4.8 model. Then again, this is the first thread of this nature that I've seen. Hopefully it's not all that common and I luck out.

All N62 motors are susceptible to the Valley Coolant Pipe leak. Why it was made to be unserviceable is beyond me. As for coolant changes every 2 years doesn't necessarily make you bullet proof against a leak. It's just a matter of odds.
