Hi Everyone,

A check engine light popped up on my 2014 TDI Touareg Executive. I have VCDS and did a scan that came up with the following code. I did some digging and found two temperature sensors pre and post particulate filter that I believe may be the culprit. They're cheap enough that I might just replace them and see what happens. The code is for "temperature sender" so I don't know if there is a control box that these sensors feed back into that may be causing the issue.

I also did some searching on this code and while I found a couple instances of this code being thrown the root cause was never defined. Is there any way I can drill deeper into this, or has anyone had this issue and resolved it? I am out of warranty so bringing it to the dealer to fix is no longer an option.

The sensors are cheap enough and I could get the both for ~$120 and see if that cures it... Unless the general experience is that that it is very unlikely that is actually the problem.

The car runs and drives great besides the light.

I'm assuming the best solution is rawtek delete + malone tune. Unfortunately that will run ~$2000 but I may not have any other good choices/options.

Yes, i am 10k miles outside of warranty.

Hi everyone, I wanted to follow up on this in case others have the issue. I've been driving the touareg since February with the check engine light on. It runs and drives just fine, just the light on the dash. No abnormal DEF usage or anything like that. I am planning on deleting the DPF and doing a malone stage 2 tune with the black friday sales on right now. Given the code is for a temperature sender for particulate sensor is it safe to say the delete will solve this issue and the tune will ignore this sensor?
