However, I've recently acquired a collection of errors codes (listed below) that strongly hint that the VANOS is on it's way out - I'm thinking that maybe it's been on deaths-door for as long as I've owned the car (about 2 years)? It struggled to start one morning, and seemed to stall. Started and drove normally the second time I tried, then displayed warning lights the next day. The warning lights on my dash are "EML" and "Check engine". The car continues to drive pretty much as normal, but I have noticed "lack of power at low revs" being more pronounced than I remember.
The car is taking a trip to the garage on Thursday (23rd) so my local mechanic can have a poke around to figure out whats wrong, but I'd like to get the opinion of you good people on this forum
As I understand it, the Pre-2006 cars have a hydraulic VANOS where the OEM seals fail. The fix for these is to install an 'upgraded' set of seals and gaskets. Is this also the solution for my 2008 N46B20 engined car? Also, does this engine have Single or Double VANOS?
