From the way things look,inspite of all the information available on the internet which u probably all have ready on ur phone,we still have ignorance being displayed here.
Please visit either wikipedia or howstuffworks.com and read about TDi and HDi esp. if you can get ur hands on the VW implementation - am sure you all know now that VW own and make engines for AUDI and Skoda....
TDi is great technology. The japanese still have loads of petrol engines on small cars to sell,and so we,the dumping site can never hope to get for example a diesel passat from jap - at least not as easily as u will get the petrol model,same with CDi benzes,TDi Audis etc. But search for these in UK,utaona! Ni plenty,and diesel engines tend to run almost forever. The one guy I know in london driving a 1.9 TDi AUDI has done 150,000 miles already,and the cars still drives like new. He still does over 52MPG with the traffic in that wretched city. Things are changing fast and we better be ready to chage with the times......holding on too much is just by the brokers to retain value of the contraptions we are currently keeping on the road.
Mechanics,I repeat,fear everything they are not familiar with. They will tell u all sorts of stories just to convince u to keep the petrol they are used to.
Don't we have anyone here with a diesel prado,VX,Passat or VW?
Dont take my word for it,research it in readiness for next time u invest in a car. Also,consider importing from Europe now that the currency is fair. You will be surprised.
