NVH for Android App

CamJam · 01-23-2022, 11:15 PM

I'd been considering buying this app for awhile, but the original price was north of $300, which I wasn't willing to part with for something that may or may not work for me. At the current price of $100 though, I was game.

My 335i has had a rumble at 65 mph for a couple years now, kind of like driving on a very fine rumble strip. No problem below 45 or over 75 mph, but at 65 it was just bad enough to annoy me. I suspected the CSB, but it was also similar to the vibration of worn u-joints, which I experienced on another car a few years ago. I also had a Mazda with a bent wheel that gave a similar symptom.

I thought that if I went to the dealer, they'd just want to take the easy way out and replace the drive shaft. $1,250 or so as I recall, plus labor. So I bought the NVH app, hoping it would tell me what I was dealing with.

It literally told me on the very first run that I had a 1st order driveline problem. I suspected that u-joints would be a second order vibration and contacted the seller at Vibrate Software to confirm. They agreed. As the u-joints are not replaceable, this was pretty good news, and it meant my hunch of a bad CSB was likely correct. I ordered a new one, along with a giubo and associated hardware, which is supposed to be replaced rather than reused.

I finished the job today and the vibration is gone. I spent about $350 on software and new parts, but I saved a lot and got some new tools out of the deal as well. I have a couple classic cars, one of which has some high-speed vibration issues, and can't wait to run the NVH software on it too. In short, I found this to be a very useful app.

BTW, if you ever need to drop the exhaust, a transmission jack and a car dolly (the kind that let you wheel a car around a garage) under each muffler make short work of removing and reinstalling the exhaust system.

CSB failures are more common than one may be led to believe

Glad you fixed the problem, I've experienced CSB failure in a friend's e92 and it's annoying. This app seems quite useful, it might just be worth the $100 if I experience something like this myself. Thanks for sharing
