I guess the only real way to tell would be to play with a ScanGauge and compare these "catalyst temperatures" with the VCDS readings of the EGT sensors. These catalyst temps may (or may not) directly correspond to TDI EGT sensors. If anyone has a ScanGauge, VCDS, and a CR TDI, this would be interesting to know. I am not going to buy a ScanGauge just to find out if it works.

Have Fun!

FWIW, I programmed the code for the second EGT sensor (fahrenheit) into an X Gauge and got no reading.

After watching all four this morning with my VCDS it looks like EGT 3 is the DPF sensor since a regen yielded a consistent 582C, 1079F temp.

According to the "Self Study Guide" (which could be in error). EGT sensor #3 is after the DOC and before the DPF and EGT sensor #4 is after the DPF which should get up to about 1200 degrees F. (600 C.).

Have Fun!

What I actually noted on #4 was a temperature of 487C 908F and consistently lower than the #3. **Edit after re-reviewing the #3 varies a lot while driving. The #4 is pretty stable, either 260C or 500C. I will run it again later today. **

Again, I have log file from VCDS if anyone knows how to share it here and wants to review it.

I just noticed that you have a new Passat. The study guide I have is for the CBEA and CJAA engines. It is quite possible that the sensors are different in the CKRA (Passat) engine. I have no technical information on this engine. You could easily be correct about sensor #3 being after the DPF, I just do not know.

Have Fun!

So,
I have the Scangauge and a 2009 TDi so, I put in the Xgauge Bank 1, Sensor 1 as suggest in the first post.
Wonderful. Just what I was looking for. But now, I also wanted to see the temperature of my DPF so I can see when a regen is happening.
I'm supposed to have 4 sensors according to the self study guide.
But when I put in Bank 2, Sensor 2 I do not get any reading on the Scangauge.
Now I have changed to Xgauge to Bank 1, Sensor 2 and assume this is the DPF.
Any ideas on which sensor# in the guide is which sensor (Bank#, Sensor#) for the Xgauge?

Thanks in advance.

I'm wondering if the 2010 doesn't report that info over OBD II

FWIW, I've tried programming x-gauges for all four of the fahrenheit Catalyst Temperature for CANSF vehicles (http://www.scangauge.com/support/xga...ansf-vehicles/).

I was able to get a reading for Bank 1, Sensor 1, which is what I believe most folks are using for monitoring EGT, and I was also able to get a reading for Bank 1, Sensor 2. I wasn't able to get any data for Bank 2, Sensor 1 or Bank 2, Sensor 2.

What I've noticed in monitoring Bank 1, Sensors 1 and 2 for a couple of days is that they roughly follow the same curve, but with sensor 2 about 30 seconds behind sensor 1, so I assume it's a sensor further downstream in the emission system.

I confirmed on the VCDS this morning during a regen that EGT #3 is the DPF temp. It was a steady 582 Degree C.

And yes, I confirmed increasing the engine RPM's during idle DROPS the temp, requiring MORE post injection durations to achieve the 582 Degrees C.

Also, post injection #3 seems to be active all the time. Post injection #1 and #2 seem associated with the Regen cycle. I logged a trip over the mountains this last week and the Post Injection #3 was always active on heavy acceleration or climbing altitude.
