Vanos broken

[alexk]

I am the guy from mtorque with the vanos issue.
Mine was making a lot of noise, with 47k km.
They changed the full vanos unit.
When I went to pick it up, I was saying that it still makes noise. They said it's ok.
Some days later, the csl sounded like it has a hammer inside.
I went to another dealer, they had to change the gearbox of the vanos.

So, with vanos unit and vanos gearbox (some... 8000 CHF later) the engine is perfect. BMW paid everything.

Don't worry. It's something extremely rare, but it might happen.
The space shuttle blew up in front of the world, a vanos unit has the right to fail.

Hmm, I remember a couple of years ago posting about the vanos problem on mine over on Mtorque, and most people shot me down saying 'they don't go wrong on E46's'

2 vanos units on mine and 1 sets of gears later.... :whistle:

Both units were tested and both were faultly.

Did they replace the gears first time round?

Did they replace the gears first time round?

Nope.

I bet if they had the 2nd vanos unit wouldn't have needed replacing, same as Mark...

Engine with Vanos OFF



The car should be back on the road soon parts on back order :whistle:

Looking at those photos confirms that I didn't have the gears changed last time, only the VANOS unit.

Parts on back order? How long are they expecting you to be off the road? Have you got a courtesy car???

[Mark CSL]

Baz the parts on back order are not for the engine.
But i told them to keep my CSL till it is all sorted before i get it back it would
just sit in my garage till it was sorted :thumbs:

I have a BMW X3 M SPORT :supz:

That's what I had when I had my brake issue last year from that Dealer, a Black one. Diesel. I actually liked it, was handy for the camping anyway. :thumbs: Shite on the twisties though, :banghead:

Any of you guys get charged for a courtesy car?

[Sailorbaz]

No, if its under warranty, the Warranty company pay for it.

If the car is getting serviced, I think you're supposed to pay £10 insurance but thats it. Normally I sweet talk the lassie into letting me off though!

[Mark CSL]

Yip i am the same as Baz :thumbs:

[bryce]

I never pay for a courtesy car whether its service or warranty.

I rarely take one anyway cos I dont need it.
