Mine is a petrol. It's been working flawless since I changed the magnetic valve.

How much time do you think this would take for a VW/Skoda mechanic to do? I got a quote from the local VW/Skoda dealer - and they have set up 4,5 hours of work on it, which to me seems insane. I mean, are they charging me for the time it takes to cool down the engine after having me driving it there?

Hi, thanks for the reply! I'm aware that the start stop error is a an extra thing that pops up and has no bearing on the fault itself. And yes, it has the electronic wastegate actuator. Which after spending the better part of the entire yesterday researching seems to be out of the voltage specifications. I'm not 100% sure which turbo is in the 1.8 TSI, but it's the CSJB engine. Sadly I don't have a proper diagnostics reader. The one I have can't read out the voltages from the actuator. If I had that it would make doing the adjustments a pita. I don't even think I'd have to disasemble the turbo in order to do it, even if its thight fit back there. Do you think I can just adjust the actuator rod manually without the voltages until the error message is gone, and without having to do a firsttime adaptation with vcds or obdeleven?

I should probably also note that I tried jerking the actuator back and forth from closed to open this morning before I started the car, and when I did, the error message didn't pop up, which kinda reaffirms my idea that it's the actuator that is stuck or seizing a little.

Hello! This is a Skoda Octavia 1.8 TSI 2015. So, I had this error code pop up intermittently for a little while when starting the engine from cold. But now it's coming on everytime I start the engine from cold. The error doesn't pop up when the engine is warmed up, and I'm not noticing anything on how the car drives, fuel economy and such. Maybe a little higher oil consumption. I've been to the local VW/Skoda dealer, and they are saying the boost pressure regulator needs readjusting, and are unwilling to quote me a price on it. I myself am not to sure about that. So I've been looking for other explanations for why the error message has been popping up. So far the main reasons I've found are the wastegate actuator seizing/not going to correct position. Which seems like a more probable to me. And I've looked at this post on a 1.4TSI as somewhat of a guid one how to fix it. https://www.golfmk7.com/forums/index.php?threads/how-to-fix-the-turbo-wastegate-rattle-on-the-mk7-golf-1-4lt-tsi-140-150ps.340805/ So my questions are these, how easy should that actuator be able to move? Because mine is moving, but I feel like I'm having to use alot of force (probably a subjective view) for it to move. There's no rattle on it, and it feels secure in place. Also, if I were to remove it, wash it, sand it and lube it up. Would it require a reprograming after reassembly? Could the fix be as easy as cleaning with breakcleaner, paper, and high-temp grease on the acctuator spindle?

I had the exact same problem on my 2015 octavia 1.8tsi, and after taking the heater matrix out for a flush with no effect and checking and removing the silica bag I found the answer on another thread here. After changing the magnetic valve the car feels completely new, heat comes out of the vents after just 1min of driving instead of 20min. On a sidenote, I almost sent back the part that fixed it because there were two different magnetic valves there, and one of them are different that the one in the thread. But after looking for a second time I found the proper one. 😄😄
