Re: Audi A3 2011 2.0 TDI (8P1-CFGB) Crank no start, no DTC c

I agree with you 100%. I always like to test everything and want to be sure what the problem is and I like doing as much asI can with the scope. But as you said time is a critical factor in this line if work and I think that there is not enough time in most cases.

What I would do at this stage is either put wps in and measure cylinder pressure, or if your injectors are already out pull the valve cover and check to see if there is anything out of place. It would be obvious on that engine

Yes and I think it shows up in 09 central electrics. and I forgot to mention as i saw in the beginning of this topic, these engines have no problems with glow plugs. the problematic ones are 3.0 tdi. so these plugs come out no problems.

I would look at the command circuit for starter relay. It could be losing power on account of bad igniton switch. Usually when ignition switch goes it throws a fault code. Something like ignition switch D. It is simple in design. To me it looks like potentiometer :D sorry for spelling.

Re: Audi A3 2011 2.0 TDI (8P1-CFGB) Crank no start, no DTC c

I agree with your Idea for voltage drop testing. As for brake switch you can see it using VCDS. There' a mvb that shows if switch is working when depressed. As for the valves, it is plausible. This Engine has valves at 90 deg. against pistons. they dont bend when piston hits. but they smash rocker a...

not the cam lobes but the sporckets are. And when they move rocker arms are the ones that go, since this is interference engine. but the god thing is it doesent damage the valves. they are set at 90 degrees.
