Audi A4 2007 2.0 tdi. I'm getting eml light and codes relating to dpf sensor. P2454 dpf pressure sensor implausible signal. I've replaced the sensor with one from tps and adapted it with vag com but code has returned. The 2 hoses going into the dpf are clear and dpf ash content is ok. Done abit of testing and on the plug going to the sensor I'm getting 7.5v on pin 3 with ignition on, I'm told the the max should be around 5.2v. Has anyone else had this and could this be the cause of the code? Thanks
