the heater cores in these cars get clogged up very commonly. pull the heater hoses off of the heater core in the engine compartment, and use a regular garden hose to backflush the heatercore. spray in one way, then the other, untill clear water is coming out. then refill your coolant reservoir and see if that helps.

Could be also MAF sensor defective! Here you have the vacuum air pipes connection picture for Audi A4 1.9 TDI (AJM engine):
