My car has been in overnight,because it's becoming a right pain to start. Sometimes,it's first turn of the key. Sometimes,it churns over and over and then spews out white smoke. The dealer phoned this morning. "it started fine (wait for it...)...are you waiting for the glowplug light to go out before you turn the key" Replying "No,I'm dim as fook" didn't get any response,so I replied "OF COURSE I AM" Bottom line,no fault codes on their computer = no action. It's just getting handed back to me as is. Infuriating and condescending.
