Finally got my 540 running right again

[barry 90 525i]

My 540/6 has benn running bad for a while. Had all the symptons of manifold gasket failure. CEL light, sputtering at idle and lack of power Was about to order all the gaskets. Changed both fuelfilters and car runs like new again! Sometimes the simplest thing is overlooked.

And what a feeling it is when you get it going like it should again! Glad you got it sorted!
