There are only 3 on the CRKA. EGT(PreTurbo), Cat B1S1(PreDPF), and Cat B1S2(PostDPF).
There is not a 4th.
Apparently the Passat's exhaust system and the Polar software for it is pretty much the same as for my '09 CBEA. The engine actually has 4 exhaust temp sensors, but the Polar FIS+ only shows 3 of them. This is just fine with me. IMHO, the pre-turbo and the DPF in and out temps are really the only important ones for monitoring regens. The only reason to care about the 4th one is if it fails - then I would whip out VCDS. In normal driving, I have no need to see the temp between the turbo and the DOC/DPF.I saw 4 with vcds
209 Exhaust gas temperature sensor 1 87.7 °C
211 Exhaust gas temperature sensor 2 109.0 °C
213 Exhaust gas temperature sensor 3 118.0 °C
215 Exhaust gas temperature sensor 4 52.7 °C
Have Fun!
