I wanted to also mention that I also noticed the engine makes lots of loud intermittent loud metallic type noises, sounds like it occasionally misfires, and nearly dies out at times when the engine is “cold” started after sitting for several hours.

The loud startup sound is unacceptable for a brand new “luxury” vehicle. Mine stickered for over $45,000.
It’s embarrassing to startup my Q3 at work after it’s been sitting all day. I wait till all my coworkers leave the area with their cars before starting mine up. My 2019 Q3 sounds like a beater vehicle from the 70’s or 80’s.

I have an appointment next Monday with my selling dealer to see if anything can be done. I'm surprised that Audi would find this acceptable. It's very annoying and quite frankly embarrassing to cold start the car. I can only assume as the weather gets colder the metallic chatter may become louder and last longer as the car warms up.

I have taken my car in 3 times and it’s apparently normal. The service department literally told me I have to just deal with. Ofcourse the sales team are trying to put me in a Q5 bc it’s a “different”!engine but not wanting to work with me on my trade and make me pay full sticker price for Q5. This is my first Audi and I will NOT get another one. I am very disappointed and feel upset. This car was suppose to be luxury and it’s not.

The noise concerned my that there was something wrong, as I just wanted to know what the actual reason was, not that it was loud.
So from reading more on the subject:
The noise is normal for a VW, Audi 2.0T engine to sound like a diesel on a cold start for 30 seconds. The 1.8T and 2.0T have had this noise for years.
The ECU startup procedure is mapped to set the idle higher, which dumps in more fuel, (direct injection is louder as well) which creates a rich condition.
What this does is that it generates more heat to increase the temperature of the exhaust more quickly, heating up the cold oxygen sensors and catalytic converters for better cold start emissions.
Once the system detects they are up to temp, the idle decreases and the O2's are used to calculate the fuel mixture more efficiently.
All cars today use this technology, it's just that these engines are a little louder.
I only notice the noise it if I am outside the car, as my music begins to play as soon as I start the engine.
Hope this helps and that others will know that the noise is normal and that their service departments are not just turning you away for no reason.
BTW: Lovin' the new Q3.

Thanks for the detailed explanation regarding the cause of the annoying loud engine startup noise in the Q3.
It appears that in order to cut production costs of the Q3 “luxury” crossover, Audi decided to put a cheap, detuned, and noisy 2.0t Volkswagen motor under the hood, instead of using the superior version of the 2.0t that’s in other Audi models .
I wish they would’ve chosen to put the same 2.0t engine version as they have in the A4 and Q5. That version of the 2.0t engine is noticeably more powerful and also is very quiet at cold startup.
I also like the quick shifting 7 speed dual clutch transmission that’s in the A4 and Q5 too.
I personally like the 7 speed dual clutch much better than the cheaper , frequently sluggish, and rough (especially 1st to 2nd gear) shifting 8 speed Tiptronic automatic Audi decided to use on the U.S. version of the 2019 Q3.

Everything that LX302 make sense. My only question is why this 2.0T liter makes this type of noise and not other models in VW/Audi line up. 2017 Golf R never made that noise at cold start and my current 2016 Tiguan does not make the noise. Other 2.0T engines in Audi’s line including the A4, A5, and Q5, all don’t have the cold start noise. I’m sure it’s fine. I’m speaking with my dealer next week for them to hopefully clarify.
