Right, I remember there was an SI fix for the vent valve vibrating which could throw up the code. If not, you can replace it as it is shown in the diagram. The intake temp sensor is part of you MAF. Have a read on how you may be able to solve that as well. Last thing you want to do is buy a new MAF as it is not cheap. :thumbsup

 

Thankyou Neal P I wasn't aware of the repair and mine certainly has not got that bracket. I have just removed the inlet manifold for a further look and I removed the vent valve and powered it for operation, it seems o.k. In tracing back the breather hose it goes to a cannister with a diaphram fitted in the top half and a chamber underneath I can only asume this is the Charcoal cannister?? when I stripped it down the diaphram was split and it was heavily compacted with sludge. Also when I removed the vent pipe oil dripped out the end. Is this cannister the route of all evil or am I barking up the wrong tree.
Cheers.
Colin.

Just rang my useless BMW main stealer they called it a cyclone valve?? Any ideas???

If you are talking about no.2 then yes, that is the cylone valve...proper name is oil seperator valve. It is the crankcase vent valve and you should really replace it if damaged, but I still think the root of your intermittent start issues is related to the MAF.

 

The oil separator will give you no end of troubles if split so replace it and see if that helps :thumbsup

It should be ALOT better

 

Thankyou all for spending the time to help.

 

Hello just an update, stripped down the inlet manifold removed the oil separator/swirl valve and fitted a new one. Refitting as I'm sure you all know took three times longer than removal! Tried the car once rebuilt and yet again the chuffing thing would not start when warm. Placed the car on Snap on's Solus machine and the only fault now present is the air intake sensor (code 14) This I have seen is not in the MAF sensor but alongside that oil separator I've just replaced and whilst it's not ideal it is faulty it will not stop it starting. I got the car warm and placed Solus on it again as it would not start and up pops Crank sensor fault!! If it turns out to be the crank sensor I may do something I regret after all this......I'm fitting one tomorrow I'll keep you posted.

 

Bloody cranksensor and 3 coil packs all at once.......Bum......

 

She all fixed now then? If so then someone doesn't like you! all them going at once :frown, don't buy a lottery ticket, save your money

 

Yes all fixed........God hates me...........
