I recently bought a 2.5tdi quattro and have found that its not exactly fast. With 150hp i was expecting a bit more. A friend of mine in a 130hp seat ibiza out accelerated me a by a mile and i have driven the new golf with the 140hp tdi engine and it seems like lightening compared to mine. When i bought the car it needed the crank breather changing which i've done and now it doesnt smoke adn drives smoothly adn well but not particularly quickly. I was thinking of getting it plugged into vag.com at a local specialist who charges 40 quid for the priviledge, is this a good idea? I've read forums about MAF's and was wondering if the vagcom would identify if my maf is not working as it should be. Also my engine light isnt on so i have had no warning that theres anything wrong with the car just a feeling that the car is not as fast as it should be and htis may be down to the ECU controlling things. I have been driving it like this for sometime with no problems but as i now think there may be a problem should i limit my miles until i get it checked? Any advice welcome. Cheers.
