Yeah they are.
Just pings me off that they charge 1500 for a part that is recon and possess the same inherent design issues. I recon you can get an engineer to re-do it for a LOT less and end up with a better item all round...
Am no expert but a big part of the problem is the pressure they run at. I think I read a thread somewhere about someone fixing their own... and it was relatively cheap.

You could just opt to ditch it. The cars aren't undriveable without a VANOS but the power delivery is very different I accept.
www.bmsport.com do vanos removals on their race cars...you could ask them about it.

Not sure I'd want to commute in a car that has been set to run over 5k rpm and >60% WOT though...
I'd like to drive a car with the VANOS removed to see how it does drive, but I've got no complaints about the low end tractibility of my car - it'll happily pull 30mph in 6th around town. At that point the VANOS hasn't kicked in, and tbh around town I barely get the chance to go over 2.5k rpm. From that perspective I wonder if I'd even notice it's removal? And then of course when I'm really giving it the beans, back comes all the power at the top end.
Just a thought, and as I said, not based on experience.

The key component of that sentence being race though. A race car will never really have cause to drop below 60% WOT and as the VANOS is there it help low end tractability, it becomes superflous in a track based application.

I get your point ASBO and I do agree. My race car would be a pig to drive around town but then it's got big lumpy cams and is mapped for power. For the sake of argument could you not map a car with lower RPM driving in consideration etc surely you could iron most of this out?Not sure I'd want to commute in a car that has been set to run over 5k rpm and >60% WOT though...

Admittedly I haven't seen inside a VANOS yet but reverting back to topic for a moment, my point is simply that I presume it is simply some gears with associated bearings that mesh with the cams, some pistons and solenoids.
We already know the gears and solenoids and associated seals can be replaced, and as BMW evidently recondition them, surely somebody can do the same. And more to the point, for a lot less than the £1500 plus VAT that BMW are charging for the part alone.
It annoys me that this is an ongoing problem from which many suffer and sometomes end up paying great amounts of money for, only to be given a new part with the same inherent problems.
Admittedly, I have the fire in the belly right now due to the associated void in the hip pocket, but I think the issue remains valid...

So then Andrew has the car returned from the garage? Am with you though on the whole VANOS issue. If the `issues` could be engineeged out then i'd be keen on investigating into it. Unfortuneately the machine shop at my place of work doesn't cater for the cutting of gears - although i'm fairly competent enough to do it.

Investigated repairing a vanos unit myself a little while ago, so trawled the net and found this site: http://bimmer.roadfly.com/bmw/forums/e39/7494631-1...We already know the gears and solenoids and associated seals can be replaced, and as BMW evidently recondition them, surely somebody can do the same.

Several photos of a stripped vanos unit at the bottom of the page, it's from an E39 but i believe it's the same system.
