BTW I wouldn't advise being put off German cars as a result of buying a VW; there are other options
Things are probably different in europe where core models are made in europe, though I have my doubts about too many audi products coming remotely close to toyota's core products when it comes to longevity.
Here in the US, a lot of german cars are made in mexico or the south, and on top of that, there are plenty of low volume US only models.
I'm not aware of a good reliable german car since the early 1980s mercedes. It's almost a joke, too -especially on teh service and repair side.
Coil over plug for my wife's VW (you read that right - literally about the same time I was dumping my VW for a honda, I met my wife. She had just purchased a VW with an audi-made turbo four cylinder. Great power potential, but as a practical car, an absolute cowpie. poor efficiency, poor engineering for every part in the car, constant replacement of routine things (as a relative here who is a VW certified tech would later tell me "well, they often don't use plastics that tolerate oil contact in parts of the car where oil contact is common). At any rate, over 10 years, I put about 8 coil over plug units in that car. Not remotely close to a significant issue with it, though (only about $300 of parts to do that and easy to diagnose) - just under $40 each. If you were unfortunate enough to have the audi with the same engine, the connector was different ($90) and the same part with a third style of connector was available for a benz ($132). That's the online price, slight discount over parts counter. I often wondered what the markup on the coil was for a benz, plus diagnostic, etc.
it takes about 15 minutes to check the code twice, swap out the coil and then put all of the covers back on. dealers here charge a $50-$75 diagnostic fee for anything, usually mark up parts 200-300% on the service bill and then charge a half hour of labor. That would put a benz coil over plug fix at around $475. All for a core part (sans the connector issue) that would wholesale around $20 and by someone with a cordless ratchet and a code reader, could be changed in less than 10 minutes).
These kinds of things are why I love the older incremental improvement philosophy that 'yota used to use. Even the older platforms from some of the domestics were like that (not uncommon to drive a ford panther platform for over 300k miles without anything but routine service, but also plenty of domestic stuff now that struggles to have very many get to 150k miles even with near five figures of repair bills in the wake.
Between the wife's VW and mine, 110k miles of total driving yielded about $11,000 in repairs, with about 1/3rd of that warranty covered.
My toyota vehicle is 13 years old in two months. Unscheduled maintenance so far is $79.
The audi and benz vehicles the same size class as my old VWs were off the road before the VWs even were.
Cousin-in-law who is a VW tech likes to buy the old diesels (pre scandal) for scrap price ($200), go through them end to end, drive them a while and then sell them for $3k. He does that with about one a year. "They are fun cars for a mechanic, but not good to own if you can't do all of the work on them".
