Everything has to be carried out to BMW instructions for the dealers to put the warrenty claim in i think. BMW tech rep said they have seen the problem before and it orignates from the cyinder head, valves and variable timing. I had two options either to re build the cylinder head to incorporate the modificatiosns of the new wngines which include new valves, timing chain, cams lifters or other option replace the engine with the modified cylinder head. Apparently its the early MCS that are giving the problems.

So should everyone with early builds sell as soon as possible before everyone knows and they become untouchable ?By the way ,I'm on my way to Carmax right now to see what they will give me for mine .
