Audi A4 b7 2.0l tdi 170 help with vag codes
 

Just pulled these faults up as I'm having problems with glow plug light intermittently flashing and when I turn the engine off it seems to shudder to a stop. Also intermittently bad idling and strong smelly exhaust but no smoking. Car runs well otherwise. Thanks in advance for any help.
