Hello, I have a 2011 Jetta TDI with 190k miles on it and it is being a pain in the butt , just can't depend on it now. It's rare, but maybe one out of 10 car starts my Jetta will take a dozen or so cranks to start the engine or more sometimes, twice it took over 20 minutes to start then next time she does good with only two to three cranks. Once she starts she runs great, but getting to the point my wife is scared to ride in the Jetta. As stated this is all in Tenn summer warm weather. I sprayed some key dry lube in the key cylinder and the key turns with no problem, it did seem to help a little , but still had one horrible time getting her to start in a busy parking lot with dozens of people watching and wife getting mad. I installed a new Continential EGR Valve air regulator flap and cleaned the EGR valve real good hoping this would help, but still having the same problems of starting. Also changed the fuel filter (no metal flakes in the fuel filter housing) . No engine light on. Thanks for any advice on what to do next.
