The latest news is the use of FOUR WHEEL DYNOS!
Our son has a 2015 TDI and we are more concerned about the DSG trans fluid change, required at 40k miles.
The dealers want $600 to $800 to change the gearbox oil!
Not THAT much work, and you can buy the supplies for about $100, but You need a VERY SPECIAL’ OBD tool to reset.
He has 20 k on it now, so we have some time.
If fuel drops around $2 (5 cents/mile), the trans oil change cost 2 cents mile!
One of my vehicles would crawl right off a FWD only dyno. I guess there are a lot of full time 4wds on the road now.
What does the tool actually reset? A “change trans oil” light or message?
