B7 acceleration problem

I'm running a 2015 B7 and when you floor it on the highway during acceleration the car loses power for a second then starts hard acceleration again. It will continue to do this through the pull and will sometimes go into limp mode. I had a cracked charge pipe on my 335 that caused limp mode but I can't seem to find that being a big problem on the N63. Any ideas before I let the dealership rape me?

Thanks

Have you changed all ignition coils and Sparkplugs?

Have you scanned for any codes?

If you don't want your dealer to "rape" you, it is good to know what you are dealing with before going in.

Just did a scan and it's a misfire on cylinder 3. I have ordered a coil pack to see if this fixes the problem.

Keystone, where in Texas are you? I'm in McKinney and have found a couple good Indy's to work on my B7 after it was no longer in Warranty. I used to take it to Classic in Plano and my service Adv. was Pat Arnold. He is now at Autoscope in Plano and they have some really good mechanics there and are less expensive.
