Car won't start-2004 Jetta TDI BEW
This is my first time on this site. Went to start my car yesterday and it cranks but no start. The rpm indicator has no indication while cranking. I have checked the 109 relay and it's good. I'm starting to think it may be the G28 crank sensor. I found in my Bently that the gray plug for it is left of the engine filter but there is no replacement procedure for it. Where is the actual sensor located? Can I get to it from the top of the engine or do I have to get under the engine?
