[s-cars] Fault code 2113

[Thomas R Green]

Wylie,

If the CPS code is a result of the crank gear keyway failing and  
allowing the gear to turn on the crank, then you should be able to  
visually verify that the engine is not in time by the timing marks.   
If the key is intact or even if it is cracked but still in the keyway,  
it couldn't be the cause of the 2113 DTC.  I recommend concentrating  
on changing the CPS without disturbing the timing.  The original CPS  
have been known to come apart and also become erratic from oil leaking  
on them and collecting debris in the slot.  I don't have enough data  
to say which sensor is the most reliable, Audi or BB Automacao.
