Soooo... Jack.
A while back you referenced the possibility that one or more injector was dumping fuel which causes excess smoke, which gets pulled back into the intake manifold through the (which is just trying to save the planet, dammit). All this gums up the inside of the intake manifold, the electric butterflies and of course gives my DPFs black lung.
You indicated how I should try and get some temperature readings to figure out what cylinders were the issue.
Well for the life of me I don't see how I could isolate cylinders. The exhaust ports are in a location that the sun definitely doesn't shine, and instead of a header there is a large cast manifold on each side (which would seem to preclude isolating one jug).
And up top, the injectors are actually under the valve cover. Like way under the valve cover.
I've looked at the procedure for swapping and setting injectors. I would have to obtain/make the specific tools needed and honestly I'm not thrilled with the idea of keeping this car until fossil fuels are illegal.
So I queried the VW dealer to see if they could just do them all. Well that was a mistake, because the injectors are over $800 each. NFW am I going that route plus labor.
So we've scheduled the car for diagnostics (I feel retarded handing my car over to someone for that part) and "injector service". I can't wait to see what that entails.
Since doing the controllers I can get it to boost well if I drive it with a bit of a foot. The woman is more timid which causes it to not advance the boost sometimes.
Just last week it pitched a fit about the headlights being inoperative. They light just fine, but the side-light (the one that comes on when you turn a corner) is out on the left one and the right housing is turning into a fish tank.
Anyway, can you suggest anything I should specifically ask them to do on this car?
