I know I have a lot of Carbon buildup in my engine (well my mech told I did so I trust him) but I was wondering if there is a good way that "I" can clear some of this out. I talked tomy mechanic and he said they remove the fuel lines and use a crazy chemical. Is this a process that I could also do? or leave it for the pros? (trying to save the 200 or so dollars of having htem do it)

had amazing results with it on my old Coupe GT.<ul><li><a href="http://www.bgprod.com/bgconsumer/bgservices/44k.html">http://www.bgprod.com/bgconsumer/bgservices/44k.html</a</li></ul>

Comes with can of BG 44K, BG MOA (oil treatment), and an bottle of Audi-labeled fuel treatment (can't recall the exact product name). Seemed like a decent deal compared to buying 44K straight up at another car parts store. Anyone know of a better place to buy 44K locally?

I've heard good things about BG products from Audi techs and even the milder Audi fuel treatment (which the label recommended for every fillup on dirty U.S. gas) seemed to have some positive effects on my B5 S4.

Which do you think is a better way to clean out your car's engine, and much more fun to boot? If you don't roll the car that is!

Which is probably what the shop was recommending doing to his car. That process does require specialized equipment, so it's not something you can do yourself.

You can try the 44k first, which I recommend, but the fuel/air induction flush will do a better job.<ul><li><a href="http://www.bgprod.com/bgconsumer/bgservices/fuel.html">http://www.bgprod.com/bgconsumer/bgservices/fuel.html</a></li></ul>
