OUCH! My Thursday morning beat down. I might have to change my handle to NoFunGuy. Sorry for the confusion. As punishment I will be compelled to drive a gasser for a couple of days while my TDI is getting it's Phase II done.

I had actually forgot I started this thread, but the same issue was reported while I was reading some other recent threads, which jogged my memory. it seems that a number of repaired 2015 Passat TDIs have this seemingly-behind-the-dash vibration/shaking issue at low RPM. Unfortunately, I have not made any progress on diagnosing or eliminating it.

i really think its the dieselly sounds of the engine earning it's keep. If you roll the window down does it sound like its coming from the engine or from inside the cabin?

Our driveway is pretty steep, unless I keep in manual mode in first, she'll make it up in second and the clatter is just not needed.

I don't think you're harming anything, if need be try and keep the RPMs up by holding in first.

I understand the diesel lugging sound you are talking about...I've had a 2005 Jetta TDI, 2012 Passat TDI (which I had for awhile after it had the fix done), and 2014 Jetta TDI in the past. However, with this 2015 Passat TDI, this rattle starts after the engine starts doing its business, and it sounds more like a muffled vibrating stiff plastic trim piece (like I used to experience often with the 2005 Jetta, but with that car, I could usually find the offending piece of plastic). I've had the window down, and it doesn't sound to me like it is coming from the engine compartment, but it is hard to tell.

For me, this rattle doesn't only happen when going up the driveway. I can be going downhill pulling up to a STOP sign, and as soon as the RPMs drop, the rattle starts.

Then a couple of you jumped in with your own TDI's which are identified as having a manual transmission by the screen name or in a later post which I am crystal clear on. So I was not talking about your TDI since you are not the OP of this thread. Hope that clears it up for you...

*OP = Original Poster (as in the person who started the thread)

Yeah, and it gets confusing when people don't quote a post.....it makes it sound as though it is their personal post......

gottcha, yeah trim rattle is tough to peg down, start hitting things. the "loop" portion of velcro is great at silencing rattles, other thing that I've read is medical tap used to silence squeaks.

Just an update...I took the Passat in for the Phase 2 update, and whatever they did fixed the rattle/rumble.

Also the Passat is running better now too. Prior to the Phase 2 update, it seemed to me that car was idling too low (based on my prior experience with TDIs). Sometimes it would seem to nearly stall when shifting into gear and taking off. That is all gone now. I reported this problem to the service agent, so perhaps they adjusted something else, or maybe the Phase 2 software update took care of the problem.

you get phase 2a and 2b or just 2a?

2a is the sensor/wiring , 2b is the DPF EGR system stuff.

The service ticket says 2A, which consists of coolant added, a pipe, a conversion kit, and a software update for ECM.
