Dropping my car off tomorrow for (hopefully) the soft stall fix. It's happened a few times so far, and it's been more and more apparent within the VW community. at least 50 NHTSA reports so far, and VWoA, and VW Germany techs have weighed in, and there seem to be some solutions that are starting to make sense:
So, with 2019 GTIs, VW replaced the oil pump with a new one, and updated the oil spec to a lighter weight, 0w20, compared to 5w40 over the past however many generations of the E888 engines that they have been running, no problem. ...so, what seems to be happening is that software/computer whatever is misreporting the intake camshaft angles on the intake valves because it is getting a different PSI from the new oil compared to what it is expecting. Once the vehicle is up to temp and you start approaching low RPM at low speeds, the computer might be shutting the engine down because it doesn't know what is happening...or something.
But honestly, who really needs to test this stuff properly before sending them out to the market; isn't that the kind of thing we only expect from the Italians?
Basically, these are the fixes that are working:
--intake camshaft replacement and installing some cam magnet thingy to keep it at the proper angle? dunno what that is about, tbh.
--replacing oil with 5w40 spec, and install that cam magnet thingy.
--other owners have reported that simply doing a throttle body adjustment in VCDS has solved the issue
--Turning off transport mode in CAM Gateway and Central Electronics doesn't really fix anything.
Germany is pretty much recommending replacing with the older oil spec and adjusting the cam with magnet, or replacement, or both, and it seems there will likely be a software update within the year, so that the computer is properly tuned to the lighter oil spec that this model year was, supposedly, designed for. Interestingly, I've read that the newest APR tunes that were recently released call for 5w40 oil as well, supposedly independent of these known issues. That could also be that they are just working off the previous model years' specs. Canada VW website still reports 5w40 oil for the 2019 engines, even though the same Canadian cars are documented in the hood stickers to be specced for 0w20.
Apparently, some owners of the brand new GLI are reporting the same issue, which makes sense. Same engine and power train, I think. So, I'm not sure if the fix now will mean that when the official recall and fix is in within a year, it means I need to go in to get this work undone? Wonder if it will impact mpg in the meantime?
Being a VW owner for the first time in my life...this is so exciting!
