The 2.5 hours is definitely a red flag, assuming all he did was to change the oil and rear diff fluid.
But not sure how the rear diff pinion seal could have anything to do with the noises and CEL? When that seal starts leaking, you lose diff fluid obviously, but you shouldn't get any noises until the fluid is gone or almost gone. I'm not sure about how different the 1LE eLSD is from other rear diffs, but a leaking rear diff pinion seal is something that is typically repairable by just replacing the seal itself. I've never heard of the diff needing to be replaced, unless it ran for a long time with little or no fluid.
The other thing is I'm not sure how the tech could have screwed something up while changing the rear diff fluid, where the pinion seal would start leaking? The only thing I can think of is that he used the wrong fluid.
Since the car was trouble-free for 3000 miles, and you first noticed a noise the day after the service, prior to putting the car on the track, it's reasonable to assume the tech screwed it up somehow.
For those of us who don't know, is FL2K a drag strip?

Yea man that's what puzzled me too, I dont know how a pinion seal that was leaking for no more than a day could have wrecked a whole diff.
Them putting the wrong oil or amount was a concern of mine but unfortunately they don't let me in the back and hangout to observe what they do and check it out. I was also worried about what Dave-ROR with regards to the eLSD separate fluid chamber, there's room for error there. Not saying that's what happened for sure but it's definately suspect considering the timing and circumstances.
Fl2k is a drag and roll racing event. 3 days, car shows, burnouts, and a lot of the big youtubers like Cleetus McFarland draw a big crowd. Definately a fun time.
I'm stopping by today to get an update and make sure they checked everything else with regards to the TC system and brakes acting up, as well as the reduced power mode and CELs relation to the diff issue.
