The oxygen sensor on my 2015 BMW 535D Diesel has become faulty. BMW has extended the warranty on Oxygen sensor for diesel vehicles to 10 years OR 120,000 miles. My car is still within 10 year threshold, but at 137,000 miles. It seems BMW has set a mileage threshold exactly before the parts start malfunctioning. The faulty oxygen sensors cause very bad fuel consumption. The mileage warranty threshold be lifted or increased.

Recently purchase this vehicle from BMW of Greenwich. Drive it less than 200 miles - the odometer at the time of purchase had 55,000 miles, the engine looked perfect upon visual inspection. The fax report had a failed emissions inspection in the record and a second inspection days latter as apassed. I detected burnt smell coming from the engine, and immediately stopped driving it and called the vendor. The vendor has the car towed to their facility and it is there being (hopefully) repaired. I used my own computerized diagnostics tool, that showed error HO2S 12 Heater Control Circuit Specifics: Engine code P0141 -?" 02 Sensor Heater Circuit Malfunction (Bank 1- Sensor 2) Downstream What does that mean? ? Heated oxygen sensors contain heating elements to help them get to operating temperature quickly in order to minimize the amount of time spent before they can provide feedback to the powertrain control module. Sensor two is downstream of the catalytic converter ensures the catalytic converter is operating efficiently by monitoring the air-fuel ?This fault alters fuel burning and compromises the efficiency of the engine, compromising fuel efficiency. Now - There is no reason why a sensor this important be faulty, and therefore, it is my opinion that my new car could have gone in flames with me and my family inside. I have been reding on the internet that these sensors are prone to failure, what in my perspective could be part of planned obsolescence, which is an outright scam to swindle owners out of their money. If i am worng on the planned obsolescence perspective, I am certainly right of this being a very serious defect, that should be corrected immediately. I request that you investigate and request the manufacturer to recall these vehicles, as they present a grave risk to life and property. ?
