NHTSA Complaint #10362195 — 1997 BMW 540I

I EXCHANGED THE LAMBDA SENSOR OF MY CAR A COUPLE OF MONTHS AGO. SUDDENLY MY MILEAGE WENT DOWN AND I STARTED AN ERROR SEARCH. SINCE I WAS DOING A COUPLE OF OTHER THINGS ON THE CAR I DIDN'T COME UP WITH THE SENSORS UP FRONT. UPDATED 11/16/10 *BF UPDATED 03/23/11 *BF SO WHEN IT CAME TO THEM I RECOGNIZED THAT THEY WERE GROUNDED THROUGH THE EXHAUST WHAT THEY SHOULDN'T DO AT MY CAR! WHEN I ASKED THE MANUFACTURER THEY DISMISSED EVERYTHING AS IF IT IS NOT THEIR FAULT. AND THEY KEEP SELLING THE LAMBDA SENSORS FOR A RANGE OF CARS THAT DEFINITELY DO NOT FIT! MANUFACTURER IS BORGWARNER BERU SYSTEMS GMBH! LAMBDA SENSOR IS OZH 173 HTTP://BERU.COM/ENGLISH/PRODUKTE/PRODUKTIDENT.PHP?S=OZH+173&EANR=0824010207&ACTION=STEP02 THE DANGER RESULTS FROM THE IMPLICATIONS OF THE GROUNDING: THIS LEADS TO A HEATING UP OF THE LAMBDA SENSORS WHICH THEN MIGHT IGNITE UNBURNED FUEL IN THE EXHAUST. THIS FUEL WILL DEFINITELY BE THERE AS THE GROUNDING ALSO DESTROYS THE OUTPUT STAGES OF THE ENGINE CONTROL UNIT THAT ARE RESPONSIBLE FOR THE FUEL MIXTURE. THE CAR WILL ULTIMATELY FATTEN UP, RESULTING IN UNBURNED FUEL GETTING TO THE EXHAUST AND BEING IGNITED BY THE HEATED UP LAMBDA SENSORS! THIS IS WHAT CAN BURN DOWN THE WHOLE CAR DURING DRIVING AND ALSO WHEN STANDING AFTER A LONGER TRIP! SO THESE LAMBDA SENSORS DESTROYED MY MOTOR CONTROL UNIT, MY CATALYTIC CONVERTERS, ETC. I WOULD BE GLAD IF YOU COULD RESEARCH FURTHER INTO THIS AND NOTIFY ME OF THE STATUS! UPDATED11/23/10. *JB UPDATED 12/01/10. *JB *TR
