jon-

What tyre did you fit? I ended up with a set of AllSeasonContacts, you can see them tested here https://www.tyrereviews.com/Article/2020-Tyre-Reviews-All-Season-Tyre-Test.htm in 18" on my vrs and was happy with them, even if the steering was a little wooly

It's titled turbo pressure control in the app so I was guessing maybe something to do with the waste gate control

I agree with your theory but bottom left is boost pressure isn't it? I'm still not really sure what bottom right is

I don't think this turbo has variable geometry, and a blocked cat is a good idea but it wouldn't end up flowing ok at the end of the RPM. My money is on wastegate. Maybe.

The car had been run on 95 but it was on a second tank of vpower. Fuel alone wouldn't cause that massive drop in power / torque at 3500rpm

Nope, car has definitely never been remapped, my dad owned it from new!

No codes at all! I'll go out and check fuel trims, I'm not sure I can see knock in my app. I just threw new plugs in and I changed a coil pack that had melted to the Head but no change at all. It's coming on boost so strong, it shouldn't be that much torque that low down.

I just noticed, over 400 nm of torque, and I am 100% sure this car isn't mapped. No wonder it feels punchy at low RPM.

I recently posted about a flat spot at 3500 rpm. As it's gotten worse, I did what any idiot would do, I went to dyno it for a laugh. The healthy looking curve in the dyno plot is not my car. The unhealthy one is. I did some data logging too, and everything looks fine from the cars point of view, until it gets to 3500 rpm then it dumps all the fuel it can and pulls timing, but it doesn't pull back on the throttle. I might be wrong, but the car seems quite torquey pre 3500 rpm so perhaps a stuck wastegate? Are these electronic ones? The previous owner spent the first 48,000 miles mostly off boost.

Hey, Sorry if this has been done, but I'm in a bit of a rush. I've booked some time on a rolling road to do some geeky intake testing for my e92 M3, to see if upgraded panel filters / cones really do help for a video, and as I own a VRS I thought I might as well run that too. I realise videos like this have been done before, but I'd still like to run it, and I'll be going full geek to get pure data. The running order for the M3 is new OE -> aftermarket panel -> full cone intake system -> no filter at all. I'd like to mirror that with the Skoda to see the difference between NA and turbo engines. I'm assuming a K&N setup will be the most common fitted one, but I was wondering if anyone had any pro tips as to what this engine likes and doesn't like Thanks in advance.

Thanks for the idea, I'll check it out. If I can work out how.

Tell a lie, there was one fault. "P1899 Coolant shut off value short circuit to ground / open circuit. Fault store in ECU (static)" I need to clear it and see if it comes back.

Thank you for the reply! All servicing has been done on the yearly schedule by a skoda dealer. The most recent service included the air filter, and I've definitely tried the Italian tune up method I'm not sure it'll be the fuel filter as it's flowing fine at high RPM but I'll see when that was last done, and obviously the oil filter was just changed. The plugs would have been done in line with the yearly service interval on that car, so at the 4th year or 40,000 miles I believe. Again, these will have been done by skoda. Interesting theory, I'll follow it up! See above Thanks again all Just to be clear, it's not a missfire and I'm not sure the average driver would notice the flat spot, but it's definitely there and worse when warm.

Hey All, I've been searching a lot but I can't seem to find any answers for the MK3. I have a 2014 51,000 mile car which has just had it's 6 year service. I've had the car for around a year (bought from my dad) and it's always been my daily car, so I've generally just driven it for MPG. Recently I used it for a wet handling tyre test, and noticed when it's warm the engine gets really flat between ~3500 and ~4500 rpm at full load. Now I know it's there, it's easy to spot on the road from 3rd gear onwards. No fault codes, full service history, generally been driven super softly etc. All I can find online is cleaning the TB, but that was for a MK1 with the 1.8! Thanks in advance.
