Help with 2009 Clubman S Carbon Issue

My 2009 Clubman S check engine light went off this week. It has 25,000 miles on it. I drive it a lot, about 500 miles a week (mostly highway @ 60+ MPH). The dealer had it for 3 days. Below is the exact transcript of what is on the repair invoice. In short they performed a carbon clean of the valves, clened combustion chamber and fuel injection, replaced the spark plugs, AND UPDATED SOFTWARE. I'm a little worried that this will happen again when it is out of warranty. They said to add fuel additive every 3000 miles (i.e. Techron). Anyone else have this issue? How common is it and will the Techron additive solve the problem? Is high mileage driving of the mini not a good idea? Finally, what is a "TC CASE"? Sorry for all the questions, but need to know how big a problem this is. THANKS!!!!

There's tons of info on this carbon buildup issue, I think the only other option is to SeaFoam your mini before every oil change
