I am telling you about 60 minutes however in normal conditions where you do the diagnostics this time could be shorter. We are assuming you had not caused any damage to your catalytic converter by driving only short distances at slow speeds. I doubt it but its of course possible...

at least for half an hour drive with speed 110 km/h or faster, control the temperature of the exhaust system (should be at least 600 oC) and status of NOx catalytic converter sulphation (should decrease) using ISTA D or INPA. 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.

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.

Engine warning lights

Scenario 1: there are only error messages regarding NOx sensor, error messages 30E9 and/or 30EA are not present.

Like the OP, I have strong exhaust smell after acceleration. The rough starts were found to be due to the vacuum leaks and a failed MAF Sensor (hot film was burnt off/open). This made the car super rich because of fail-safe programming thinking there was too much air coming in. deleting the long-term trims/adaptations (offset values for Lambda and NOx data, etc.) of the sensor with ISTA D (procedure of encoding of new NOx sensor, described here). You can also look over the complete errors and explanations of NOx sensors in BMW. BMW NOx Sensor – Error Codes ReplacementsA 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. In addition it might trigger AdBlue-System fault on the dashboard and iDrive screen. BMW nox sensor errors and explanations P.S. It’s not possible to delete error messages 30EA and 30E9 easy way (for example, delete and – problem solved). 30E9 will re-appear in a little while, the status of 30EA is saved and visible in INPA info and/or history menu section. If the 30E9 was present – to renew Stratified charge mode, you will have to perform (successfully) operation described above or install (and register) a brand new catalytic converter (if you don’t mind spending EUR 3000 on that). Without information from the sensor, the engine management software cannot accurately work out how the engine is running in terms of the fuel mixture and air-to-fuel ratio. As a result, this causes the engine’s electronic brain to assume a worst-case scenario and make the fuel mixture run rich (increased amount of fuel) to ensure maximum power in poor conditions. If you find that your fuel economy drops during regular driving, this could be a tell-tale sign of a faulty sensor. Unstable and erratic idle

The problem with BMW is that not many people have sufficient knowledge to diagnose the car not to mention fixing it.

Real Reviews

error messages relating DSC. Solution: drive 10 .. 15 min, switch off ignition for 2 .. 3 min, then turn on; 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.

With the introduction of N43 and N53 series engines in 2007, BMW began to incorporate more sophisticated technology into the marque’s basic specification models. One of these new developments for these motors was a new engine management computer – called a DME in BMW terminology – as well as a development of their variable valve timing tech.

Within 60 minutes you should clear your catalytic converter. The car is gonna sound and drive better. Park's of Hamilton act as a non-independent credit broker. We work with a number of carefully selected finance providers and manufacturers who also offer finance. Deleting/clearing the adaptations of NOx sensor is a very important event. If they are not cleared, there can be scenario that MSD80 identifies seemingly high value of NOx level after regeneration cycles and registers error message 30EA (MSD80 is supposed to initialize forced desulfation of NOx catalytic converter to clean it) or even 30E9 (aging of NOx catalytic converter) after some time (if desulfation sessions are not successful or possible). Also error messages 30D6, 30DE, etc. can appear.
