Hi Bunnybasher, got exactly the same problem, think i've narrowed it down to the MAF, if i disconnect it the performance is the same but the power loss/missing problem stops and the check engine light stops flashing on. I have searched endlessly for a replacement new part (I assume yours is the same, i.e. a bosch unit 0281 002 092) and cant find one for less than £360!! went second hand and got one for £30, fitted it yesterday and didn't work!! not sure now if its another faulty part i bought or if i'm barking up the wrong tree! anyone got any idea how to test these things?
