Re: M-5 Vanos replaced

My service rep told me it was the same as getting a whole new VANOS. All I can tell you is the car runs like it did when it was new.

Re: M-5 Vanos replaced

Do you know what it was or does? Is it just a simple check valve?

Re: M-5 Vanos replaced

The fix was called a new engine VANOS repair kit part 11-36-7-832-855 labor $945 parts $749.25

Wasn't it a check valve?

To prevent "leak-down" when the engine was shut down?

Re: M-5 Vanos replaced

Sure would appreciate the details. Thanks

Re: M-5 Vanos replaced

I don't know what parts they replaced. I'm not at home so I can't look at the invoice. I recall it was billed as a VANOS upgrade...my service tech told me that the "upgrade" basically replaced it with new. It's never run stronger.

Re: M-5 Vanos replaced

Which part of the VANOS was replaced? That sounds awfully cheap for the whole system.

Re: How common are Vanos probs on 2001?

I had the service bulletin done that solves the cold-start clicking sound, but otherwise no problems on my early 2001 (now at 12000 miles).

Re: M-5 Vanos replaced

My 2001 Z-8 with 22,000 miles has had no issues. However, my 00 M-5(same motor as Z-8) needed the VANOS replaced at 50,000. It cost $1500 and now runs as strong as ever.

Re: I have a 2000 with 30k miles and no problem

I know yours was warranty, but how much otherwise?

Re: How common are Vanos probs on 2001?

Mine was replaced at about 3000 miles- no trouble since then.

How common are Vanos probs on 2001?

Want a companion for my M6. You folks previously mentioned that
build date after June, 2001 minimized Vanos probs, but how common were the problems before that? Would they have been sorted out in car with
10-20K miles? I gather the fix runs in the $3K range - am I correct?

Many thanks as always. Your board is as helpful and civilized as the e24 folks.
