hi please help me !!!! ive just got a 130 tdi golf and its only doing low 30 to the gallon
ive put a air flow meter on it and a egr valve and it has made no difference im driveing it fairly steady and getting very low mpg and the odd puff of black smoke it also seems to be a bit under powered/lazy compaired to my fabia vrs which has the same engine

Sounds as if the turbo isn't working, but if that was the case you would presumably know instantly?

If there was no boost, the boost pressure transducer and engine control would not allow excess fuel.

There is no substitute for getting the fault codes read - which you should do. My money, however would be on the fuel temperature transducer - cheap and easy to replace.

659.
