What did you do to your mk7 today?

I'm not sure, from my caveman understanding, fueling doesn't seem to be an issue. I think it's going to turn out to be some weird red herring that I need to chase down.

Just a shot in the dark, but the early 19's would choke like that below 4000 rpm and it ended up being due to requested and actual timing not being in sync. Do you have a way to log requested vs actual timing?

I doubt the cause of mismatch would be the same (in the case of the 19 VW didn't program the sensor for vvt for the lighter weight oil), but you could have a failing sensor.

Quickly realized the tow hitch mount for front license plate is difficult to place in a spot that doesn't interfere with the PDC sensors lol. Went with the EOS one.

I think I finally got it, but not super happy with how it looks. Might grab the front grille bracket one, since that would keep it out of the way of the sensors.

Didn't think about this when I bought it..

So quick question that may be dumb, but it's something I've never seen before.

Should the valves be closed when the engine is off, or are them being open normal?

I'll post the actual pictures in a minute, not just a picture of a picture. But the intake valves on cyl 1 are definitely open...

Depends on where you are in the engine's combustion cycle. Some cylinders will be open, some closed.

Thanks, I've just never seen that any of the times I've scoped my cylinders before.


Alright, here's some albums of actual pictures.

Cylinder 1, with the open valves. Valves themselves look reasonably clean, but looks like the chamber is full of carbon?

Cylinder 2, tried to manually rotate the engine, but couldn't do it. Weak :(

Cylinder 3, again, couldn't rotate the piston down :(

Cylinder 4, the one which had the oil on the plug. Don't see any signs of oil intrusion, but can still see a little at the bottom of the spark plug well(?). Could be holdover from before?

That Depstech camera is badass.

For $70, it's pretty good.

Oh, and here's the actual plugs with about 500 miles on them. 1, 2, 3, 4
