Hi,

I have remapped superb 280hp, 2018 with 155tkm

Under start of load turbo whistle, and after sport mode driving aggressive for few mins at night, I stopped, and feel seems burning smell and open hood turbo was glowing,

I checked with obd pressure seems fine, what should I check or is time for new turbo?

I have no idea. But just wanted to comment on your beautiful car! If you have more pictures put them up in the picture thread for us all to drool over!

2busy? Is that the Škoda version of 2sexy?

I had a B5 Audi S4 2.7 bi-turbo with KKK K03 turbos and the weaknesses were two-fold:

1. Split in the various post-turbo rubber hoses which caused pressure drops and overspooling and,

2. Running the turbo hot and then turning off meant oil would sit in the veins and cook, leaving a film of oil on the inside…this would then restrict the oil veins and cause oil starvation issues. Oil starvation would lead to bearings running dry and overheating.

On that basis, if the turbo is starting to get hot and loud it may be something to do with oil starvation and the bearings, which would then cause play in the shaft. But this is all speculation. Best get it checked.

Or, you know, Garrett Powermax 1…

And yes the car is gorgeous.

Maybe just old oil from small leak burning off a now much hotter engine.

Id suggest not stopping engine if turbo is hot. Make sure you keep it running for a bit for turbo to cool down before cutting off the oil supply.

What type of "whistle"? In terms of tone?

I had a Peugeot turbo whose 'whistling' was more of a moaning, and this was prelude to a failing bearing. No oil leaking or burning.

How long since remap-and how aggressive of a remap?
