I've just pulled the engine cover off my March 2018 (build December 17) GTI PP and it doesn't look to be dual injection. I also have that particulate filter in the exhaust system. See here page 9 for photo

10k mileage it runs really smooth and returns very good mpg.

Most of those other manufacturers offer longer warranties than VW, so less worry for the consumer - even Alfa Romeo offer 5 year warranties now. Most mace also implemented MPI as VAG did. I'm hoping that VAG have removed the tech because it's no longer required to keep coking at bay.

The MPI was never for anti-coking though was it? Wasn't it purely for particle emission control in itself?

[quoute]The engine itself doesn't have to fundamentally change to give you a hybrid, just tie in with supplementary electric motors. [/quote]

I think the answer to that is "it depends"

Quote
We have hybrids to supplement power at the top end, I do wonder, for the sake of economy why we haven't really had much in the way of front end electric working? Imagine a petrol engined car with only 3rd/4th/5th/6th/7th gears and 1st/2nd is taken care of exclusively by electric motors for cleaner and more economical city crawling.

That would make a lot of sense actually, I wonder why nobody has done it? Complexity issues? You'd still need hybrid capability in low gears in case of no charge though.

Getting a car moving requires a lot more energy that keeping it going at a steady pace. Whilst it sounds like it would make sense, it’s would be incredibly intensive on the batteries.

All electric cars manage It. Don't forget that starting up a fuelled car is thirsty work too, even if stop-start tech has made it a little easier. Could get around being stranded with no electric power by having the petrol engine generate some electricity if needed. It does sound complicated - but all hybrids are.
Whey ya bugger! It's finally arrived after an 8 month wait....

Here's my 245 engine which I picked up this morning. The car was built late 2018. Judging by the images on VWROC there's no MPI...

Here's mine, a May 2018 delivered (April 2018 build) GTI 230ps (so not performance pack) DSG. Looks to me like these still have the MPI ?
