Remove the cam cover, remove the spark plugs, turn the engine to number 1 TDC, put a pencil in spark plug hole number one and twist the crank back and forth and make doubly sure you are at TDC. Now loosen the four bolts at the front of each cam sprocket, check TDC again with the pencil and rocking the crank, now take the pencil and lay it across the flats at the back of each cam. Twist the cams very carefully so that the pencil sits flat on each cam square. Snug up the sprocket bolts and use the pencil to check TDC again! Now check the cams again. Repeat the procedure until you have the cams flat and the engine at TDC.

SOURCE: Does a 1993 BMW 318i have a timing belt or a timing chain?

Hi some of them have a belt but yours being the M43 engine is a chain, the only thing to listen for with them is chain slap or an rattling around the chain area, a bit of research on the M43 engine also shows that the chain should be changed after 100000 miles as they become weak, Just joined here and found this unsolved i know its a bit late but hope the extra info helps

SOURCE: Cam position sensor error.

It's not enough only rebuild yours engine !!!
After new camshaft position sensor instalation and timing perfectly alignment you must scan the engine control computer and erase these error, actually all errors stocked in memory. The best scantool is VAS device used by VW-Audi dealers, VAG-COM by RossTech (cable + software 704.014, 805.01, ... on CD), or also Bosch KTS 540, 570, 670, ...
RESET = erase errors from the engine control computer memory !
Yours engine control computer don't understand if you only replace damaged sensors with new others! Errors still remains in memory affect engine runing!
Best regards!
