There are a few things that cause "limp mode"

On an audi I once owned it was the air flow meter. but it could be a boost leak amongst other things. (do a search on limp mode)

And also get the car scanned for codes before you start spending money.

If it is an AJM 115PS TDI PD engine the most likely cause is sticking turbo vanes and the code "17965 - Charge Pressure Control: Positive Deviation P1557 - 35-10 - - - Intermittent" would be stored.
