@nta16I agree about the usefulness of being able to view parts listings, all good stuff, well after you have had reason to search for many parts in all areas and so trained yourself into how the catalogue was designed.
My best extra feature I ended up with when buying my next laptop was touch screen, very handy when searching through parts listings!
I used to buy the odd Ekta disc to keep me going, but now that these "nice" Russians seem to offer free access to some hooky genuine up to date VW Group catalogues, I've stopping buying these Ekta discs, goodness knows what nasties they are sending down the line though as is said, especially in computing, if it is free then you are the product, gulp!
Edit:- probably not that you will end up using this, but when these engines were built, the factory fitted version "a" of these plugs, when I replaced my wife's 2015 Polo's plugs, the plugs I got were version "b" - I can look up if you are interested, and let you know if it was the VAG parts code that had changed or the NGK model number that had changed, but in my head, I think that one changing was reflected in the other - so if the current plugs have an "a" within their NGK model number they were probably not replaced and if they has a "b" in the NGK model number they have been.
The coils, VW Group went through a very bad patch coil reliability wise but that was back in maybe 2004 > 2008,this I think was mainly due to VW's suppliers being encouraged maybe to include more local content and the desire to reduce costs to the factories, this meant coil manufacturers ended up moving East wards which was not good initially, my wife's 2002 old Polo had proper old European Eldor coils made in a proper old European country like Germany and only had 2 coils fail in its 13 years from new with us, her 2015 Polo has Eldor coils made in Turkey, which concerns me a bit as Turkey is well known for state sponsored "copy" factories, so there could be more than one "Eldor" factory although that should only affect anyone buying via ebay etc, the move East wards lead to some bad habits and high voltage insulation was a casualty - and so many VW Group cars had early coil failures between 2004 and 2008, in fact most people that bought new Audis with the 1.8T engine, spent a lot of their early days of ownership driving around in I think Sourers(sp?) things got that bad. Audi dealerships in Europe tended to grab a loan of older stock " so okay" coils from Skoda dealership car stocks, sad but true. I have always considered Beru to either have similar issues or were unreliable even when manufactured within "old" Europe, others might know different. That was just background chatter concerning VW Group coils, which from my personal experience, is in the past as things have been sorted out or at least improved.
