Clean if necessary Read out the exhaust-gas temperature after the EGR cooler while engine is cold (stopped engine), then start the engine and check the increase in temperature for plausibility Check the vacuum supply of the changeover valve for the bypass flap of the EGR cooler Starting from Free DPF Health Check. If you drive a relatively new car, there are usually a few sensors and cameras in place to help keep you safe. My post above references a TDI club vendor that offers this part. Sometimes this is due to the pressure to breastfeed. Try our Symptom Che. I assume now that the backpressure value is from a sensor upstream near the turbo, and that the DPF pressure reading is after the DPF and added to this upstream sensor to create a before and after delta-pressure. SI B18 03 16 Exhaust Systems September 2016 Technical Service That broken wire seems to be for exhaust gas temp sensor before cat B2390 and its connector X2390 (like shown in previous picture). The symptoms of this issue may vary, but commonly include reduced engine power and increased fuel consumption. My post above references a TDI club vendor that offers this part. At this point I rehooked the exhaust pipe connection and ran a DIS exhaust pressure test. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $154 ive recently changed my egt sensor,,fault codes etc,,doing the back pressure test even with the codes the car was fine and ran fine,,after the sensor fitted,,codes cleared and never came back,,then checked last weeks around 2 weks aferthe egt change,,and the codes are back ie 4175 and 4185,,car still drives fine and back pressure and egt temps seem fine while looking at live datagot some.
