N54 Vanos Issues

N54 Vanos Issues
Hi Guys

So a little background to my story, a few months ago while my car was at the shop for a separate issue it was decided we would do valve stem seals under a claim from an aftermarket warranty. Long story short, the claim was rejected due to seals being a wear and tear item and the job had to be done cash as everything was already stripped, fast forward a month or 2 and this n54 does not want to co-operate.

Head was sorted, everything assembled, timing done(using the timing tool) and the car started on the turn. All that was left now was to replace the waterpump as the unit was constantly spinning, but then we start the car after a few days and after idling for a bit the idle goes completely off, car throw's codes (not sure on the exact code but it was vanos/timing related), so the mech opens up everything again and finds the exhaust cam timing off, he re-set the timing, and started it, but it goes off again. This goes on 2 more times and the last time we find both cam timings are off.

Mech says I need to replace the vanos gear units which is coming to about 19k for the set. I found a guy that says he can repair my units with a 6 months guarantee but my mech says the units cannot be fixed.

Can somebody please shed some light on this matter, its been 4 months now without my car and it's becoming really frustrating. I'm not really in a position to spend 19k for new vanos + 6k for a waterpump over and above the 18k already spend for the head.

Any advice/guidance regarding the timing and/or vanos gears would be appreciated.

TIA

Hi.
Ive got exactly the same problem. I have already changed the water pump and thermostat and done the head. I have also found a guy that is able to recondition my vanos gears with a 6 month guarantee
Let me also know if you come right as i would also need some advice.
I was going to take my vanos gears to him on wednesday.

Pls let me know

Thanks for all the replies guys.Ty

@MoB123, let me know whether the recondition helps, I've put my car on hold for now until I know for sure what's wrong, I'm just not convinced 2 properly functioning vanos gears both give up at the same time simply because we opened them and did not lock a spring inside, I may be wrong but no sense in spending money on guesses.

@NuBe93n54, what solved your issue?
