SMG Hydraulic Pump in an E92??

First off, thanks to the forum for helping a newbie enter the world of M3 ownership, I look forward to spending a lot of time here.

Just picked up a 2013 E92 w/DCT, the car has about 1500 left on the warranty so I took it to my local dealer for a few items. I had another dealer do a PPI so nothing major, just a broken cupholder and jammed rear sunshade. I also noticed a humming noise that would occasionally come from the area above the left rear tire after turning the car off in warmer temperatures. Told the dealer and they advised: "no fault found test drive vehicle and verify some normal noise from SMG hydraulic pump under vehicle at times, this is normal operation of vehicle and no fault found at this time."

Correct me if I'm wrong, but isn't SMG the E46 auto/manual? Or is there a different part on the E92 called SMG? I searched the forum and couldn't find anything, some others reported the humming noise but couldn't find an answer as to if it's normal or is a problem. Just want to make sure all is good before the warranty runs out, aside from this car is perfect, passed PPI with flying colors.

Thanks in advance for your help!

Try a new dealer, they obviously don't know anything about M cars. It's a DCT not a SMG in the E9x.

Yeah I'm looking around for a good independent shop, there are quite a few in OC. My main concern is whether or not the humming noise is an issue or normal so I'm not hit with a major repair as soon as the warranty runs out. Not going with extended warranty, I'll take that $5-6 grand and put aside in a repair/mod fund

Could've also just been a typo at the end of a long day of work. You guys sure are quick to judge.

Yeah overall I've been happy with the service at this dealer, they handled warranty repairs another dealer tried to blame on me. They seem to deal with a lot of M-cars so not sure if they meant another type of pump was making the noise. I'll monitor for the next thousand miles, doesn't seem to impact driveability.

maybe its the brake vacum pump cycles on and off. but if it comes on every time you step on the brake, you might wanna replace the brake vacuum sensor before burns out the pump motor.
