:wub: just been looking at the tis with regard to changing this aux belt tensioner, came accross 2 types, tdi and tdi with unit injector system. can someone please explain what that is to me and which instructions should i follow

we got the 98 110 tdi afn code engine thanks

TDI with unit injector is the PD engine. The TDI 110 is not a PD engine.

so does the 110tdi non pd engine have the automatic tensioner at the top of the engine ? or is there another auto tensioner somewhere :wub:

No, just the one, on the top of the belt.
