Cam Vario Error

[mudman2]

Loren whats your take on an S (mine) with a wicked stutter and CEL. PIWIS gives CAM VARIO as the error. Plugs/coils check out OK (they were replaced a while ago)

This feels like 4 cylinders are not working.

Dealer is working thru fault diagnosis procedure with help from atlanta

under warranty --phew

Was your car one of the one that needed the 1/04 W418 W418 - Updating Software In DME Control Unit? If so, did they do that update?

or

8/04 2 2470 Engine Operation and Performance Complaints

or

2/05 W612 - Replacing Accelerator Pedal Module

Two out three of these required a DME software update - have they done that?

I have had many DME updates along with the DME Control Module (4) , 05 Transmision fitted and on and on. I have the worst hesitation ever, dies sometimes.

Had lots of front end vibration then this after an overnight stand
