I changed oil in 06 tdi jetta and then went for a short drive and all was well. I then parked in garage overnight and in the morning It would not run. That is it would show glow plug heating and everything looked normal and it would crank but no start up. then I discovered that I had put wrong oil in it. 15w40 . I have never had crank starter before so I don't know it the oil pressure indicator icon is to appear after three or four turns of crank time. Is this normal or has the oil affected the pressure switch and can that stop engine from starting? any help would sure be apprieated thanks , Spen
