From 96-97ish, TDIs monitor the GPs by watching the current drawn and setting a CEL if the current is not correct, which implies that a GP has burned out.  A bad connection in the system will also set an "intermittent" code. 

FYI the code will not go away after you fix the GP - it must be cleared manually with a scan tool.

on the newer TDI's, will a failed glow plug turn on the CEL?  I do not think it will.

With the muffle installed you can not remove the lower belt pulley on the crank gear to attach any type of home made crank lock to keep it at TDC when setting the belt tension.  It just takes more farting with it to get it perfect and it takes time.
