Hello, i have Skoda with broken engine 1.9 66kw(AGR) what have wastegate turbo and etc. So i want to put 1.9 81(ahf) engine on it what have vnt(geometrical turbo), also bigger injection pump and injectors, So how hard is it gonna be to control the turbo, plus have to change map sensor, n75 valve(because wastegate gate turbo uses pressure, but geometrical uses vacuum) and also something more that i cant remember right now. Also can i use old ecu, or is it easier to change ecu(with 81kw soft) (will 4x4 gonna keep working), and also can i get old key working with new ecu.

Hello, my skoda octavia mk1 4x4 rear wheels are in negative angle, as more i put weight on rear, then more it goes in that angle. Its eating my tires!!! (both wheels are on that angle) If anyone have had same issues, please let me know.

I got all working, back fuel pump had problems, and because of that it drawed out of fuel. Now it works fine, thanks everyone for helping!!

I just changed fuel filter, bleeded air out of the fuel filter and thats all. And before fuel filter replacement there were also much bubbles coming out of fuelfilter

Hello, I have again problem woth my skoda, now airbubbles is coming from fuel filter and engine is shaking. And in some time fuel filter will have air pressure inside, so what could be the problem? I think that its the return valve problem what is in top of the fuel filter.

Yes, it is not showing rpm with diagnostics, but it runs, so I dont know

I have vcds 12.12

And I changed oil and filter, tryed another oil pressure sensor, still shows warning and if I unplug oil pressure sensor cable then warning light goes away. Also outside temperature shows ..C.. tryed new sensor but Car have driven 250000km, so I dont think that oil pump is broken, could it be any other sensor, what is giving false information to the module. And diagnostic scan tool wont detect engine module, so anyone have any solutions?

And also tachometer is not showing rpm

My Skoda octavia Kombi 4x4 1.9 tdi 66kw engine oil pressure warning light is flashing, abs light is on(all sensors seems to be okay(obd II diagnostic shows all for correct speed)), and hand brake light is flashing and in the beginning beeps 3 times. I hope that someone have had same problems and knows how to fix them.

So do you have any solutions?

Hello, what could be wrong, if my obd II cant communicate with engine module, other modules are communicating, like abs, AWD etc
