I'm getting a fault code 'exhaust gas temp bank 1 sensor 3 circuit low', it used to go away by restarting the car, but it's gotten way more frequent lately. So today I changed exactly this sensor, cleared the fault codes, and it took an hour of driving before it came back. May the issue be with the cables from the ECU? Or any other issue may cause this error?
Surprisingly I have a 2013 passat tdi and this looks similar to my engine bay I have to change mine as well with the new one you installed what is the location of that sensor ?
@@smutnychlopczyk2947there is a risk of FAP not re-generating if ECU know sensors are faulty. So I wouldn't drive too much like that (or at least don't do too much short distance travels)
@@Street_Fitter Thanks pal. Thought my diagnostics was wrong... I looked at live data and it showed 4 channels for sensors but physically I could only find one. I must have replaced the wrong sensor...... doh...
Wrong sensor mate will burn out in no time there's two types of DPF for these cars as some DPS get hotter than others yours is like mine it gets very hot that is why there is a shield around the actual sensor get the part number off your old sensor is the best way they are not cheap mine was £120+vat
So I got that one directly from the parts supplier instead of just getting a random one off eBay was £130 Inc vat. Been in the car a couple months now so far ok but they have made mistakes in the past. If it burns out within the year I can always return it so I'll see what happens
