Vanos problem

Right guys and girls, need a bit of help. Did a vanos rebuild including rattle rings a couple of weekends ago on my 2003 3.0i z4, noticed a difference straight away. Just put Carly on to check things and I have codes related to vanos! No EML, just in Carly. I have replaced coil 4 and put in a new camshaft sensor...still no joy! What have I buggered up? Also, this is a bit dumb after the event but did I need to get it timed?

This is the big question. I hadn't read the car for a while, so I don't know. Camshaft sensor is odd, I replaced it due to the error 27b5 and now I have a full camshaft sensor error!
To be honest, the whole vanos refurb was easy, can't see how there is really anything I have done wrong to get errors like I have. The only other thing I can think of is that Carly isn't actually clearing codes it should.
 
You really need INPA to run through VANOS diagnostic and test. It could just be a case of the car having to re-learn end points etc.
 
Thanks for the reply, will give it some more time then. No engine light so I may be jumping the gun, will try and get inpa sorted on my laptop.
