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...

John in Indy.

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.

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.
