Hey all,

I just had the water pump and thermostat replaced after it failed on me at 49k miles. Sadly, I had to drive it for about six miles in LA traffic to get home with the coolant warning on. To the best of my (and my shop's) knowledge, nothing was damaged internally and no hoses were blown.

Now that the car has just come back from the shop, the Service Engine Soon light is on solid yellow (reduced power available) and when the car shifts above 3k, there is a cut in power and a big jerking feel.

I exclusively use the steptronic paddles and have found that if I roll off the gas, letting the revs fall below 2.5k, shift, and then hop back on it the jerk disappears.

This is a brand-new problem that only started occurring after I got the car back.

Anyone have any ideas or thoughts??
