Hello fellas!

Can the "17748/P1340/001 - Camshaft Position Sensor (G40) / Engine Speed Sensor (G28): Incor. Correlation" issue be fixed without removing the whole front end.
Passat 1.8T, Runs fine but it throws this code! (no other codes!) im suspecting the chain is off 1 link i counted 15 from one cam mark to the other. Please help!

The chain needs to have 16 (technically it's more like 15.5) teeth between the marks with the CCT extended on top. No need to pull the front end, but you do have to pull the intake cam if the marks do not line up.

Thanks guys! Well, I was able to slide the timing belt off and move the camshaft 1 tooth counter clockwise. The car started and ran fine bout now i get this code an CEL 16396- Bank 1: Camshaft A (intake): Advance Setpoint not Reached (Over-Retarded)
Any ideas or comments are greatly appreciated!

There are two parts to the static timing (or mechanical timing), the synch-up of the crankshaft to the exhaust cam via the timing belt, and the synch-up of the intake camshaft with the crankshaft (indirectly, via the chain).

If you had a problem with the second, and you fixed it by adjusting the first, you now have two problems. One by itself is VERY serious.

Do NOT turn the engine. Unplug the battery, and go into service position. Open up the valve cover, and pull out the intake camshaft. Set the TB correctly to make sure the exhaust cam sprocket is also at TDC, and then set the chain to have the correct number of teeth, and with the camshaft marks lining up with the arrows, and both TDC marks on the dot.

This is an overview of what you need to do, not a step-by-step. At a minimum, you need to have access to a Bentley manual and follow that.

The timing belt was not the issue, the timing chain between the 2 camshafts (under the valve cover ) is the problem. Make sure you line up both the timing belt marks and the chains.
