ive just bought a 03 galaxy tdi130 and im wanting to service it . ive always done my own but ive never serviced a diesel before. oil , oil filter, air filter im ok with as i guess its the same as a petrol but what do u do when it comes to the fuel filter and glow plugs? any info would be most welcome( like where they are and how to do it) . if i do manage to service it myself, which im hoping will it turn off the service light on start up or does this need to be turned off via the computer system? cheers.
