Right just getting out of having a meeting with Nissan , the tec said the car had two faults
1) starting issue - which was found to be a corroded earth wire under the washer bottle to the engine Which has now been fixed for free .
2) burning oil , the car is burning oil "crazy amounts" was over the top but none the less it looks like it is so it has to be done, it's abit strange as it only seems to smoke when idling but clears up when it is Rev'd
They are adment they have not caused it but have agreed to do a few hour's work for free so can't complain really .
They're going to start with suction pipe on plenum then work through cam covers etc
I Will update again once I find out a cause
Yip Mileage was 47085 when I went today it was 47087 they said they test drove it .
And tank was 3/4 full when I went today it was still 3/4 full
