In some cases (which is rare) we will find that the vanos is broken. In these cases we will either replace the broken parts if we have extras or sell the customer a used one from our shop or a new one at their request.

Good to hear Chris, thanks for the input. I need to find out more about the adjustment of the VANOS, why does it need adjustment in the first place? Is it a side effect of the bolts coming loose in the intack side or something else?
