Strange GTI "Problem"

[SSnide]

Hello all,

I've come to report another possible issue with my 2015 GTI. This one has me baffled. It could be very simple, but let's see what you think.

I don't have any video or audio, as it only occurs seemingly at random. These are the conditions:

1. DSG in manual mode

2. Air conditioning on

3. Accelerating moderately in 1st - 4th gear

4. Between gears 2 and 3 and sometimes 4, there is a "clunking" or rattling sound coming from the engine bay. It is always between shifts, when my foot is still on the throttle (about 2/3 way down). It happens between 2nd and 3rd or 3rd and 4th gear. I don't notice a loss in power or feel anything weird in the drivetrain.

What could this be? It doesn't always happen. Maybe only once every two weeks or so.

I have that sound too and I think everyone else complaint about the same noise. I don't think no one knows where that noise come from.

probably the DSG clutch? I sometimes noticed this, but when i'm in traffic while DSG engages.

I have similar issues. Lots of clunks when shifting.

Try this: put the car in park, and rev the engine. AC off, windows closed, in a silent environment. Listen to the engine as it revs. Are there any noises? Mine had a weird gurgling noise when revving to 2-3k rpm in Park or Neutral, while the revs are returning to idle.

I dropped it off at a new dealer with an awesome shop foreman yesterday. I will update when I know whats going on. I get clunks and metal-on-metal rattling when going over potholes or small bumps, and when giving the car quick throttle and releasing. I think its either 1) dual mass flywheel 2) clutch packs worn (which would make the Dual mass flywheel worn), or 3) a dead transmission.

I used to notice that, too. It went away or became unnoticeable once I had clutch pack #2 replaced. Don't rush out and get the same replacement, though. I was experiencing erratic DSG behavior and hard shifts after I'd been out on a rough road circa 21k miles. It does feel really smooth compared to what I got from the factory, though.
