@automass please let us know after few days of driving your car with changed plugs and coils how it is now.

Could you please make o photo of your wrapped in DEI gold foil wiring and share it here? It' be nice if you'd also point an earth connection for the coil pack wiring on that picture. It would be helpful for many of us. Big thanks in andvance.

Which plugs would you guys recommend for Octavia 1.4 TSI CZDA MY 2016? It's 68 000 km now and still running on OEM plugs (Bosch I suppose). Thinking to change them before winter with oil and air filter. Any NGK would be better? Which number will be apriopriate to CZDA engine? Thanks in advance for any advices.

wlado93 wrote he succesfully updated H24 0245 to 0515. Not sure if I'm right but I have Bolero 5Q0035840A hardware H25 software 0252 (updated almost 2 years ago from 0245). Would 0515 work in my hardware? IF so any changes or differences comparing to 0252?

Thanks Garrycan. I was thinking about your post typing about delaying change of plugs till december. If something is working properly there's no need to change it. "Tired" plugs would have signalized it by problems with starting the engine or constant jerkinnes while accelerating or at idle. Don't have any of these things. So will wait till december, maybe end of november and will do it at next service. It'll be great to drive at the beginning of winter on fresh oil, filters and plugs - winters in Poland can be cold and humid.

Thanks BRUN but I know which model of plugs to buy. It will by NGK although factory puts Bosch.

@RicardoM how is your engine running now? Has your problem reapperad till today? Any other advices on this?

Thanks TheWanderer. Gonna do it by myself (got all needed tools and informations). Many says plugs in CZDA engine can work properly longer then service manual indicates. That's why I suggested to delay changing till next service. Have to think it through.

Is there an option in VCDS 20.4.1 to check plugs condition measured in percent or volts or something like that? Mine Octavia 1.4 tsi 150 bhp is 62 000 km and theoretically I should change plugs. But engine starts fine at each outdoor temp, accelerates normally without hasitation. The only worrying things I've noticed is a bit of shakes while driving slowly first few meters on cold engine in the morning and small shakes from time to time on hot engine on idle at traffic lights. I plan to change plugs at next service in december. What do you think - should I wait to next service (car will be 70 000 km then) or change them now?

Has anyone heard about an update for CZDA engine? I have about TPI for CZEA engine which fixes light shakes of the engine. Read many CZDA users posts on here and other forums complaining about light shaking on idle and at mid revs. Some of them even saw Check Engine Light. On russian forum found information about TPI 2043772/4 from 16.08.2017 which describes a fix of this problem as engine software change and gives priopriate software numbers. Can someone check it out for example in Erwin? Thanks a lot in advance.
