2004 BMW Z4

Okay the z4 has been checked for air leaks negative. New disa new ccv valve and associated pipes. Rubber caps at rear of manifold changed no air leaks and all pipes from air filter changed. Showing running lean banks 1 and 2. Cleaner in fuel and maf sensor cleaned. Engine light stayed off but came back on after 450 miles usually comes on around 150 miles after light has been cleared. Today car is going for new lambda sensors hope this is the problem cured.. also had new spark plugs fitted. So so frustrating now. But the car drives beautifully I hate this light arghhhhhh
 
Well cars been to Indy this morning they have cleared engine light and reset everything back to factory settings. Showing fuel mixtures bank one and two and Mass AIr Flow Sensor. So order part and get new maf next weekend. Hope this sorts the engine light issue
 
So codes were 8223 8224 mixture banks one and two. Had codes cleared and maf sensor fitted hopefully this will keep the engine light off. Anybody else had these codes..
 
There is a fella up in Accrington that has several good condition roofs for sale. I cant recall what the firms name is but if you PM Road Warrior he will be able to help as he purchased one a few months ago.

Hope all the work will pay off with your problems on the zed mate.

Cheers, tug :thumbsup:
