Intake air temperature sensor?

Intake air temperature sensor?

Well i unplugged that and the car was boosting at 0.8bar, plugged it back in and hitting 1.3 bar again.

However, today, car ran fine first 20 mins, then hesitancy, boost flickering around 1.1-1.2 bar WOT.

Then reverted back to steady 1.3 bar full power mode.

Then the next time i give it some wellie, its back to hesitating.

This is at 16 degrees outside temperature.

Starting to pee me off a bit tbh, just spent £200 on tyres and wheel bearing for the damn thing.

Oh and i sourced a replacement crossover to turbo rubber hose coupling which has already went on fire and melted.

It sounds to me like your having similar issues to me.
I have, maybe, the same/similar symptoms. I do know, however, that my PCV system is blocked and this will definitely affect boost.
I went to my local main dealer today to collect all the parts needed and I forgot to get coolant!
Nevermind, will get it later. Total cost of all the parts was £325 and that includes a new thermostat housing and coolant temperature sensor. Now I just need two days clear to fit!!

How about starting by replacing your broken engine oil dipstick and mounting your OTE turbo pipe correctly!! Only needs a 6mm short bolt. Dealer can supply.

Haha. Yeh i have the torx bolts for the pipe mount. Because i had to shorten the ote pipe to turbo hose coupling due to a split, the mounts wont line up. A silicone replacement is in the post. As for the dipstick. I had the etm off that many times. I managed to snap it lol. Done the same on a t-5r few years ago. Self tapper screw remedies it for time being. Seals are intact.

If you datalog mass air flow, maf voltage, boost pressure, boost pressure voltage, coolant temp, air temp, air pressure, you might show something weird, like a out of spec maf or something.

I think VIDA could do most of that.
