Fuel wouldn't cause any issues no. As for the whistling, a completely standard 1.4 tsi you should only mildly hear the supercharger.

You’ll be looking close to or over 2 grand rebuilding it yourself if you don’t have the tools at your disposal.Worst case scenario can you make your money back selling it spares or stripping it?I’d personally start stripping it and see the extend of damage first mate, then go from there and see where your at and calculate the damage to the body into the matter. Can put you onto a few bodys that have rebuilt these blocks if need be.

Have fitted a universal(chinese) one myself, does require an extra bit of mounting to the crash bar however it was pretty simple. Works fine for £70

What wheel?

I know its a bit more money but a lot les hassle when you have the engine stripped, Would you not replace some of the revised CTHE parts ie the oil jets/squirters of your planning to keep the car.

Yeah mate they are adaption settings for when installing anything to to with transmission ie clutch, mechatronic or even a new box. There's a few perks to having VCDS as you can change the power steering sensitivity, turn of XDS braking system for track days etc and having the ability to code in a new or used mechatronic.

Are you basing this on video's you seen YouTube or the proper adaption settings when fitting a new clutch or mechatronic that are done through VCDS OR odis? Only way to change how the way the TCU shifts automatically is to get is mapped(which I would recommend). Other than that, Just drive it in manual mode.

You said it feels like its going to stall, You sure it isn't running lumpy ie misfiring?

Did they pressure test it bud?

Always believed that a lot of water pump issues are temp/weather related, changes in seasons. In the years owning mine the amount of water pumps that have went close or during winter are unreal. Possibly affecting the bearing. Might be the pump that's gone again or as you said a leaky hose and your only losing coolant under load. Fire a bit of carboard under your car during the night to check for leaks and if there's nothing visible id suspect your losing it during momentum. Head gaskets are so uncommon with these I wouldn't even consider it.

Plugs, coils or wiring to the coils.

I'll kick off the positive vibes..... I've had mine over 4 and a half years and apart from wear and tear parts I've had to replace: Water pump Radiator Pcv(n75 valve) Literally less than £200 in parts in 4 years it owes me, Cant grumble at all. Now i'll not be naïve and pretend they don't have issues or have a reputation of having issues because they do deserve that however if you know what to look for and find a good one.......Learn how they work and look after it they are more than reliable. 80k(130km) miles isn't a lot as I've seen proof of these doing double that mileage but I'd be looking at replacing the chain on TSI at 80k if it hasn't been done already. Personally I service mine yearly no matter the mileage, changed the DSG oil at 50k for piece of mind albeit there's the argument it never needs done but each to their own. Running a stage 2 engine map for almost 3 years now the car has been flawless even on the standard clutch, @thomasaspin Will vouch for the modifying side of things as he's put more power through is than mine.

Miltotec https://www.spoilercentrum.cz/ Aliexpress also do a variety for the mk2.

Ouch mate!, glad its fixed though and out of curiosity, How much did they charge to fix the mech in your part of the world?

Yep with no hassle as long as you keep the profile 45 or under on the tyre.
