Okay, out of the garage at about 8:45 tonight. Over the last few days (besides chasing electrical gremlins), I've been finishing-up the sound deadening project as well as "tiding" up the engine bay area and a little more.
Anyway, we took it on a 35 mile drive tonight.......... the results are very impressive. 70 mph is much quieter............... 85 sounds about like 70 use to.
Here's the run-down on the sound deadening (some stuff was posted previously, so some of this is a re-peat).
1. Removed the old OE "stuff" on top of the flat area around the engine bay lid (propane torch made it very easy to flake loose).
2. Replaced it with Dynamat.
3. Filled in the curves, cracks, etc., adjacent to the Dynamat with a thinner (not much thinner) similar material no-name brand.
4. The floor slope from the engine bay under the back seat down to the floor area, I cleaned with mineral spirits and capped over the OE stuff with the thinner material.
5. I covered all of it with double-sided aluminum foil sound deadener (similar to bubble wrap but very small bubbles). (lots of contact glue as well as spray glue)
6. While I had the inside panels off, I added bits of Dynamat and the other brand to the outer metal body panels.
7. I also installed the aluminum foil wrap in selected areas inside the panels.
8. I installed the other brand sound deadener in the air down shoots.
9. I installed the aluminum wrap inside the air filter housing.
10. I capped the air intake hole to the air filter housing with an insulated stainless steel "dog bowl." (really, perfect fit) I oriented the intake hole toward the rear.
Unfortunately, while we were out on the trial run, I got the flashing GP light and a DTC of P1650 .......... something to do with the ECU communicating with the cluster. Apparently that canceled the cruise control. May have something to do with everything being unplugged due to having the back seat out.
Well, I am basically out of time before hitting the road to Bethel, Maine for the TDI Fest. So, it will show-up as is. If I do a road trip Thread, I'll post a link from here......not sure if I will or not!
I apologize for not posting pics. Seems while cleaning up the virus issues on my PCs a few weeks ago, brother wiped out my photo program (he's here tonight re-installing everything)
