FINALLY got round to getting my password reset and iam back in action lol

ANYWAYS

Girlfriends e46 325ci very recently threw up an engine light and when i had the codes read it was saying 3 out of the 4 sensors in the manifold ( bank 1 , bank 2 etc ) were faulty...

Now i know the chances of all three being faulty at exactly the same time are slim to none ,

So after some googling about it seems to be pointing to a vacuum leak somewhere thats causing havoc with the sensors ...

Has anyone experienced this on a E46 engine and did they locate it ? iam being told that smoking the engine ( lol) can show up the vacuum leak but wouldnt have the first idea where to start on this ...

Just wondered of anyone had a similar problem and how they got to the end of it .... otherwise its into a garage with it ... something id be keen to avoid

all suggestions gratefully received
