Question about 2002 Audi A4
I'm busy with it,and it gave me the code 16725,i,ve changed the r-side cam sensor it still gave me the same code.i,had removed both cylinder heads to fit new valves.now when i start the engine,it don't start and the compression is low on both sides.that is why i think about valve timing marks can be not right.i align the rear cam caps mark with the one on the camshafts.but i'm not sure about the marks now.please help with the drawing/sketch.

The camshaft position sensor is located behind timing belt cover in front of engine.Remove cover, sensor is visable in top right hand corner.Unplug, remove 2 10mm bolts.Reinstall,plug back up,reinstall cover,crank engine.

you need a special tool that turns and pushes the piston into the caliper. YOU CAN NOT just push it in you will damage the piston and not push it in.

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!
