Scangauge 2

[amyshannon]

Hi Folks,

after reading stuff here and other places I bought a Scangauge for the purpose of monitoring my Transmission Fluid temperature on my 02 EVC.


I went thru the xgauge process , loaded in the proper codes, but next to TFT on the screen there is no number? what am I doing wrong ? how can I get it to show my TFT?

Thanks!

There is a lag in the transmission temp send. What you have to do is wait until the vehicle is running for about 20-30 seconds, and then plug in the SG. For this reason, several of us obtained a cable with a switch to turn the SC on and off rather than plugging and unplugging constantly. This is also good because the OBDII does have constant power.

Alternate idea: Torque app with an OBDII adapter. If you are just monitoring trans temp, this is more than sufficient and significantly cheaper. Here's how I set mine up: https://www.thesamba.com/vw/forum/viewtopic.php?t=677382&start=0 It's toward the bottom of the thread.

Thank you so much ! What would be other wise choices as far as things to monitor ? Coolant temp ?

[mkscott2]

Gonna leave that to others with more expertise. I really just use it for monitoring trans temp, distance till the tank is empty, and to scan for codes. Nothing fancy for me.

OK cool....i got it working,drove for 25 minutes,the TFT temp never exceeded 98 degree F.

What is normal or ideal range?

Ideal range for temp: I am still trying to sort that out for myself. There are a handful of threads on this very question, but I don't think I've pegged down a good answer yet. After a recent 4k mile trip thru mountains and plains, I found my temp to hover around 210 F. By comparison, 98 seems too low to me, but I am not an expert on this.

OBDII Coding: yes, you do have to punch in a specific code for the ScanGauge. I did not have to do so for the Torque Pro app. Haven't used other apps, so I'm not certain on what you would have to do for set-up.

Here is an update. I contacted Scangauge about the issue of having to constantly unplug it and plug it back in to get current TFT. They were great. they said it needed a software update. They mailed me out a new one with the update installed and a pre postage paid container to send back the original one. Thank you Scangauge , great customer service!!!

So the new one works fine, I do not have to plug it in and pull it out after every time I start the car. But the temp readings are way higher than the original unit was giving me . After an hour of mixed driving it got up to 228 !

This scares the crap out of me because I have heard the fluid starts to degrade at 225.

A VW tech told me 228 is normal.

I am thinking about a cooler. I spoke with a local transmission shop who said 228 is way to hot but that putting on a cooler makes no sense . He said you need to find out what is causing it to run so hot.


Another respected VW shop owner said it could be the ribbon/ bad sensors that are giving an inaccurate reading.

What should I do? It seems to be shifting fine.

My temps were similar to yours before the cooler. I put one in my '99 and temps are now 174-177 cruising on the highway. Goes up in town but you can't do much about that because there is no air flowing over the cooler. The cooler install took me most of a saturday but I am so glad I did it.

I just purchased a Scangauge2 for having real time monitoring of my transmission temperature.
I suggest that anyone that's going to try to use one of these on a Eurovan for the same reason. You should connect scangauge directly to perchase. Make sure that they preprogrammed the unit for you van.

I'm fairly happy with the unit.

Hi all,

We sold our Eurovan last year and I’m finally getting around to selling our preprogrammed ScanGauge 2. It’s on eBay if you’re interested, just search for “eurovan” along with “ScanGuage”

Cheers,
Joe
