Hi all, when I got my Octavia MK2 RS back in November it had a map on it, dpf is gutted too. Bit of smoke on startup but no other issues. That was fine. I took it to a more reputable mapper then and after that she’s been idling rough 50% of the time, with a lot of smoke, whether cold or warm. I actually find it’s worse when warm. It’s perfect if I rev it to 1k, and there’s absolutely no power loss or chugging when driving it’s just the idle. Turbo and injectors have been done with new seals. Knowing the turbo limits these cars do you think that the mapper might have put on too much fuel pressure or something? I’m at the end of my tether here as I have no fault codes in relation to this.

Sounds like a crap map - as a starting point take it back to the mapper and ask them to sort it?

Yeah at the time the mapper kind of seemed to blame it on the car but since then I got turbo and injectors replaced to no avail, currently onto him to try sort it out. Just a shame as the mapper is probably one of the best in Ireland for diesels and this has really changed my outlook on that.
