Hey Scotty, big fan of your videos. I have a VW Golf 1.0 TSI MK7 from late 2017 (European) with about 38k miles.
I hear alot on your channel about carbon build up in the valves of GDI engines and I tried to read up on it to see what I can do and found people saying that in europe most GDI VW's have a dual injection system that cleans the valves but the american ones don't. Is this true? And is there anyway to make sure mine has that type of a system? If not, should I consider doing a cleaning right now?
Thank you for the help, keep the videos up.
@dan might know
Not able to find info on the 1.0 ...Here is a VW press release in 2016 about the TSI. Haven't found anything on VW's website about dual injection. Seems the 2.0 TSI's do. Need more research, but looks like the 1.0 TSI is GDI
I can't find into on it, but if it has or doesn't have the technology isn't really the thing I'd worry about.
I'd just ask mechanics who work on these if they do have buildup issues or not.
Cause this technology isn't a guarantee - on Ford's EcoBoost Dragon they have both port and direct injections. As a matter of fact Ford's port injection doesn't ever turn off unlike most engines where it's used only for idle and low load conditions. And yet, all they have achieved is HORRENDOUS carbon buildup on the exhaust ports instead of the regular issues on the intake.
What VW actually needs to do is to redesign their engines, I'm seeing Mazda SkyActive-G engines not have any significant buildup even at 150k miles (some do, but I'd assume that's more of a PCV issue) and those have only direct fuel injection.
Have they redesigned it correctly? or is it still a typical VW? only time will tell us that.
BUT given the shape VW is in, and my prior experience, I wouldn't expect great things from them.
(source) Imagine the kind of cut of their revenue that's spent on interest payments - money that's not spent on building cars or developing technology, just interest to bankers. I'd assume that a large chuck of your cars price is just to cover their interest instead of actually being spent on building your car - and that'd explain the quality/design issues.
