VW Group engine like a 1.6 FSI...?

Hello all,
I hope that you are all well in your country, here in Italy we are still a bit worried but things are apparently not as bad as they were in March.
I'm asking if anyone knows if other car(s) in the VW galaxy did fit an engine similar or identical to our beloved (sarcasm here) 1.6 FSI. I fitted the ProBoost ECU supplied by Steve and now the yellow light is off but I have the feeling that the car is slower. I still can't understand why the moving flap of the FSI system got blocked twice forcing me to fit the ProBoost unit to turn off the light. My mechanics say that the oil vapors of the engine (that they say is a bit tired) quickly block the movement of the flap and the ECU reads an error, promptly turning on the light. Apparently it's difficult to fix it, so I considering fitting another engine and as FSIs are rare here in Italy I wonder what other VW Group car fitted a 1.6FSI engine or similar with identical mountings size etc. I know that this is probably a very stupid question but you guys have a lot of knowledge and I hope that someone might have an idea.... Thanks a lot, and keep up your good work!
Stefano

I think, for the ProBoost mapping to work as designed, the flap should be in the default rest position. Unless the manifold has been cleaned and the flap can move freely to the rest position (where it remains permanently), the air flow, and so fuel air mixing may not be correct. This may be why you feel it's a bit short of zooom (which an FSI shouldn't be).
Most of the "mess" that causes the problem comes via the Exhaust Gas Recirculation (EGR) and Positive Crankcase Pressure (PCV) systems, not from the combustion process (not carbon).
Using the best quality oil and high detergent fuel available is, in my opinion, the way to minimise the "mess" Avoiding short journeys, where the engine does not get thoroughly hot, is also a major benefit, as it prevents moisture build up in the engine, which in turn can create a nasty emulsion, which can only exit via the PCV.
An engine swap sounds a bit extreme, a full refurb of your current engine would be less trouble, and avoids the risk that would come with a donor engine of unknown providence.
As always, only my opinion.
Good luck with the truffle hunt!

Thanks Mac,
you are obviously right about the insanity of swapping the engine but it was just another idea I got while considering the irritating EML problem of my FSI. I love this car, its not slow, in fact it is appreciably faster than our A2s 1.4 petrol but it may be faster. Thins are not helped by the fact that finding 98 RON fuel in Italy is very difficult nowadays, so in this moment the FSI has a half tank of 95 and this could explain why yesterday it couldn't go over 5000 rpm in 5th gear, thus a top speed of 182-184 km/h instead of the official 200 (114 mph vs 125 mph). I could give a try again at having the flap moving and see if it stops soon again....Sadly there seem to be very few FSIs in Italy and no specialists at all. I can only hope that Timmus comes here soon: I'm sure that he could fix it...!
Thanks for the wishes for our truffle hunt. ?Next week-end Anna and I we'll be in Cherasco (Langhe) playing golf in a tournament whose prizes are not silver cups but white truffles...a great incentive to play our best.
Best

I thought you were going off to the woods, with, maybe, a truffle pig to help you! You have shattered my illusion!
As the ProBoost doesn't reqire the flap to move at all, maybe get your friends, the Gordinis, to remove the manifold, clean it, the EGRV and PCV.
Then, make sure that the flap return spring is positioning the flap at it's default position. When refitting the manifold, the vacum actuator, and linkage can be ignored, or removed (the vac line will need blanking I think).
The very poor availability of 98 octane is a very good reason to go ProBoost. 98 octane is easy to find in the UK right now, but in the future, I suspect that will change.
What pasta dish would best match the white truffle grated over it?

Hello Mac,
I'll follow your suggestion and see if we can resuscitate the full FSI movement... but as the 98 RON is nearly impossible to find nowadays, I'm afraid that I'll have to stick with the (excellent ayway) ProBoost modification. I must find someone to make the 1.6 FSI more powerful anyway!
As for truffles, we like it grated on a plate of 'tajerin 35 uova', sort of narrow tagliatelle, so called because there are 35 egg yolks for every kilogram of flour. Some butter and that's it! Or of course you grate white truffles (lots of, preferably) on a couple of eggs over easy...
Picture attached is Anna when we visited Villa d'Este last Friday, this is 'uovo in cocotte' (egg not completely boiled, still somewhat runny) covered with slices of white truffle. I'm getting hungry, its nearly nine hours that I'm at the hospital and cant wait to get back home now!
Well guys sorry for the OT, I'll get back on track immediately.
Thanks again for your suggestions,
Stefano

The inlet manifold and egr removal cleaning and refitting isn't too difficult, if you're after more power you could always look into @A2Steve turbo modification of the FSI....

Hi Mac,

As such it might not be wise to remove the vacuum actuator wihen using ProBoost. Probably my fault for giving the impression in the P1031 thread that the return spring is part of the manifold, it is not. (I have since edited that post to correct). The spring that forces the flaps open is within the vacuum actuator, it pushes the actuator arm down to pin the flaps open when N316 is closed thus providing no suck on the actuator. I suppose you could remove the vacuum actuator when running ProBoost and yes the flaps will be open laying under gravity on the floor of the inlet ports. The drawback possibly is the flaps will be completely free to move and one member recently with a broken actuator arm reported they rattled! If removing vacuum actuator for use with ProBoost wise I think to remove flaps, looks possible but I would not like to try, or do as they did and pin flaps open with a screw through the arm/linkage.
