Below you will find a list of BMW cars, which are using our listed sensors, to make sure we have correct part for your car we will need to get a picture of your old part or at least part number bmw or either continental, siemens vdo. P.P.S. As already mentioned in other topics, the problem of faulty NOx catalytic converter can’t be solved deleting it from MSD80 error map (by modifying it), and disconnecting of NOx sensor won’t help also. Generally, BMW’s engine comprises two NOx sensors; one is downstream while the other is upstream sensors. The most common causes of failure are ECU water intrusion, soot build-up on the sensor, and cable damage; due to these issues, your engine light will illuminate. For providing good quality and coverage for this significant diesel category, BMW installs diesel NOx sensors. BMW NOx Sensor Failure Causes, Problems, Issues BMW NOx Sensor Problems Assuming that nox sensor is good and catalytic converter works fine you give a 60 minutes drive over 70mph with over a half tank of petrol. Any speeds below 71-72 mph (try to maintain your speed at 74mph - you will not get stopped by police) and the tank not filled up over half DOES NOT TRIGGER desulphurisation.

A month ago I got the inspection light pop up and the battery light. Charged the battery but the inspection light came up occasionally. I got a code reader and it came up with the above fault.codes. 2AF2/4/6. Within 60 minutes you should clear your catalytic converter. The car is gonna sound and drive better. You can also look over the complete errors and explanations of NOx sensors in BMW. BMW NOx Sensor – Error Codes Replacements Since buying the sensor I’ve been speaking to people on here who all seem to say that the hissing is likely a vacuum leak, which makes me wonder how much the mechanic actually knows, and whether I’ve wasted my money buying a NOX sensor. If you have to slow down for a bit because of the cars beeing slow in front of you dont worry. You speed up and the process trigger again.

Read how to perform functionality test of NOx sensor. these error messages in the exact situation do not indicate any problems with the engine performance. error messages relating throttle. Solution: turn on the ignition, press and release accelerator pedal for 3 times, then start the engine. Attention! The average lifetime of expensive NOx catalytic converter is around 150.000km. If the NOx sensor is damaged, the engine management system MSD80 cannot determine the remaining capacity of NOx catalytic converter and error message 30E9 about the aging of NOx converter will NOT be stored even in a situation if NOx catalytic converter is damaged. This message (and all consequences – increased fuel consumption, rough run, misfires) may appear after replacement of NOx sensor (if brand new OEM sensor will be installed). If mileage on your car exceeds 150.000km we recommend using NOXEM even if the 30E9 error is not stored. NOXEM will restore full performance of your car’s engine even if NOx catalytic converter is aged, damaged or removed.

if there were error messages regarding NOx sensor – you can hope, that error messages are because of faulty NOx data it is considered “dead”. Then you have to replace the NOx sensor, reset it’s long-term trim data (as described above); As NOx is one of your vehicle’s complex components, it is a bit hard to locate the exact point where the issue basically occurs. With advanced and proficient skills, you can fix this problem. Many types of sensors like 4326879 are available in the market, which you can replace. CostsNow I haven't had the light come on for a week but the codes remain. Digging into the app a little more I'm getting 0 or incredibly low voltage reading from Bank 2 sensor 1 (which I believe is pre cat?)
