New Beetle stalls when decelerating

I have a 2008 New Beetle Convertible with 40k miles on it. It runs great, but every few days it will stall and die when coming to a stop. The problem is random, does not produce a code and never happens at speed. It always happens when you are braking and coming to a stop. I have replaced the crank position sensor as that seemed to be a potential culprit, but it did not fix the issue.

Given the lack of codes, I am trying to figure out my next move. Any guidance would be greatly appreciated.

Mass Airflow Sensor, not buying it.

You'll be back.

Get your own OBDII tool. OBDFusion is less than $10 for your smart phone or tablet, interface is typically less than $20.

Get one now, you WILL need it.

I got it recently but haven't messed with much; have been using DashCommand for awhile so i am more familiar with that app. From what I can tell; jfoj is saying that the app really shines, in its logging capability and amount of "pids" you can access? I haven't tried logging or used OBD Fusion much, so I can't really say. As with most computer obd II apps/diagnostic software related stuff; you need to spend time with them, to be able to use them effectively and get the most out of their capabilities. :) I've been keeping an eye; primarily on trim levels, boost levels, maf flow and coolant temps. These apps are nice; because, our cars hardly have any gauges on them and it is helpful, when troubleshooting drivability issues, to see what is going on. I would like to find a decent ipad mount; so, I can see everything as I am driving around and don't have to worry about it, falling off the dash! :)
