Gas Recirculation Valve (egr Valve) problems of the 2015 BMW X3

Vehicle suffers from engine 'miss' at cold start / idle, surges / lunges with minor throttle input after driving at lower speeds and accelerating. Has been into dealer for diagnostic and is under 'extended warranty' on diesel high pressure fuel pump. Have had two injectors fail and replaced, boost sensor and pipe, egr cooler and intake manifold replaced. Nhtsa posted a voluntary recall by BMW on this series of diesel powered X3 for high pressure pump replacement (21v-586) in August 2021. Owners were to be notified by mail in September 2021. Still have not been notified and checking status shows no open recalls. If pump is failing, it would be sending metal into the injectors and fuel piping. Have contacted bwmusa once again to check status of recall.

I was driving my 2015 BMW X3 diesel on route 2 west near route 128 north entrance, I lost power and "powertrain malfunction" warning alert came on display dashboard, I was able to barely coast the vehicle over to the breakdown lane of route 2 west. After pulling over to breakdown lane it started to smoke under the hood of the vehicle and with few minutes fire started in the engine compartment and less than 10 minutes vehicle engine compartment was fully engulfed in the fire. On October 11th of 2019, I have my 2015 BMW X3 brought to wagner bwm of shrewsbury MA to perform the open recall for egr cooler which was notified by BMW manufacturer. Dealer perform the inspection for signs of contamination or corrosion and perform couple of other test, but did not found the issue at that time, hence there were no repair was done to correct the open recall. Bwm manufactures should have required all effected vehicle to be repaired instead of just letting dealer inspection the vehicle, especially, bwm manufacture states that egr module could develop a cooling-fluid leak. Heated coolant could mix with diesel engine soot and melt the intake manifold. That could lead to fire.

Egr cooler failed at 70,000 +/- miles. Wasn't leaking coolant inside, but was leaking exhaust gasses into cabin and was not covered under recall campaign. BMW could not provide new updated part, but charged us for 'new / old style unit' for about $2600. Tried to work issue out with BMW corp on emission warranty, but was unsuccessful. Vehicle still has unsatisfied recall on it for egr cooler. Vehicle also is not issuing a 'def' notification. I have been in this industry for 44 years and know that this vehicle should be calling for def. I have dealt with this in Ford, peterbilt and kenworth vehicles and BMW's system is not reporting.

The contact owns a 2015 BMW X3. The contact stated that the check engine warning lights was illuminated. The contact stated that the gear shifter was slipping. The contact received notification of NHTSA campaign number: 21v907000 (fuel system, diesel) however, the part to do the recall repair was unavailable. The vehicle was taken to the local dealer where it was diagnosed the transfer pump needed to be replaced. The vehicle was repaired however, the failure recurred. The vehicle was taken to an independent mechanic where the egr valve was replaced. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not notified of the failure. The failure mileage was not available. VIN tool confirms parts not available.
