A widow whose police officer husband died when a BMW's engine suffered a 'catastrophic failure' has welcomed the news the manufacturer will stop selling its cars to police forces.

PC Nick Dumphreys, 47, was responding to an emergency call on January 26, 2020, when his patrol car veered off the M6 near Carlisle and crashed.

An inquest heard his car’s engine suffered 'catastrophic failure' spewing oil onto the tyres and road surface as he drove at high speed.

There was nothing the officer – an advanced driver - could do to prevent the crash, the inquest heard.

His widow Kathryn said it would not have happened if Cumbria Police had stopped using BMW vehicles which had a “startling” history of engine failure.

After hearing two weeks of evidence, Coroner Robert Cohen recorded an accidental death conclusion, and while he attributed no blame to either Cumbria Police or BMW, Mr Cohen used his power to recommend actions “to prevent future deaths.”

Now BMW said it would stop supplying British police forces with BMWs.

BMW told Car Dealer that it would now be ‘prioritising sales to retail and corporate customers’ and moving away from sales to the police and other authorities.

The halt of sales to the police follows a number of forces across the UK restricting duties carried out by BMW police cars featuring the N57 diesel engine, according to the magazine.

It said BMW’s International & Specialist Sales Division, based at its Park Lane, Mayfair, dealership closed this week.

Mrs Dumphreys said: “Although it is too little too late for Nick and our family, BMW’s decision to stop supplying cars to UK Police Forces with immediate effect is the first step in the right direction.

“It is glaringly obvious that these cars were not, and in my view are still not fit or safe for UK policing purposes.

“This is finally the correct decision and given that BMW were fully aware of the risks in the years prior to Nick’s death – as the inquest into his death heard - it is the action that should have been taken years ago. 

“As we heard during the inquest, the rate of the engine failures in these BMWs (between 5 and 7 a month from 2014 to 2017) was described by the independent engineering expert as “extraordinary” and by the Coroner as “startling”.

“I firmly believe that had these cars been withdrawn from UK policing years ago – as they should have been - Nick would still be alive.

“I am relieved that the safety of our officers and the public is finally being taken seriously."

After the hearing, PC Dumphrey’s widow Kathryn expressed her anger that more was not done to guard against such a tragedy.

The inquest heard that the BMW N57 engine in the BMW cars used by the force –  and in other forces - had a litany of faults, known about for at least four-years. Since 2014, this engine type was failing five to seven times per month.

“That was clearly a startlingly high level of failure,” said Mr Cohen.
