Today I didn't do anything. I had no time. But I stopped by and tried to start the car. It fired right up.. After a few minutes of idling it just started to run funny (no noises) and just died. I couldn't start it back up so I'm leaving it overnight and check again tomorow. A friend of mine suggested that maybe the oil pressure regulator is stuck and delivering too much pressure and the tappets too expand too much? 

Maybe something wrong with egr system. 

Hmmm maybe something worh checking out but I doubt it since this is an low pressure system. I takes the exhaust after DPF and routes it before the turbo

I made a new thread about this since i basically highjacked this one 🙈 maybe throw some ideas there 😁 and thank you for your help!

Well in march i did the service on my Octavia... She has done 4500km since then and the oil droped for about 2mm so my work was a success 😁
