Hi to everyone.. I own a Superb mk2 2010, with 2.0 TDI 170hp engine.. I am first owner, and car now has 560 000 km on clock... So far I am very pleased with the car, especially with the engine.. in 14 years I only replaced glow plug ones, on 370 000km and recently oil pump shaft as a preventive maintenance on 550 000km, the one I took out was in perfect condition.. and that is it.. everything else is still factory parts, including flywheel, clutch, injectors, fuel pump..maintenance is done regularly on every 10 000 km (all filters and oil). The car is running fine no problems what so ever.. Now onto the dilemma that i have, it is about high pressure fuel pump, bosh cp4.. I did hear that they can make big problems with the fuel system, and i was wondering did someone know anything on this subject, is this true? On how many km they usually fail? What can i do like a preventive maintenance?
