One to spice this tread up
OK so here is my deal. i have a 2007 750li i did a set of valve cover gaskets on about a month ago. cust brought it back complaining of the low oil pressure light and check engine light one. car runs like crap by the way. which is odd because we put almost 10 miles on the car before we let it go. so i have looked at everything i can think of. but i keep getting a code for a communication problem with the intake cam sensor for the drivers side. i cant even get the car to fire up now. we have ohmed out all of the wires, tried swapping all of the sensors around, i have even pulled all four vanos soliniods, cleaned them and reinstalled. i have re-pulled the valve cover and inspected for anything and nothing. i have smoke tested the car about five times now looking for and air leak and hey nothing. so now i have done the dreaded and put a DME in an for the big slap in the face... still the same problem... i am at a loose and not sure where to look from here. any idea?
