A BMW car engine fault which led to the death of a police officer in an M6 crash has been attributed to a "unique technical issue" seen only in police vehicles, the manufacturer behind the vehicle involved said. PC Nicholas Dumphreys, of Cumbria Police, suffered a fatal head injury when his BMW 330 failed "catastrophically" while he was on his way to a reported knife attack on January 26, 2020. A faulty crankshaft bearing had broken loose and punctured the oil sump causing the N57 engine to set on fire. It saw the 47-year-old crash on the verge of the M6 in Cumbria. In 2016, after BMW UK noted a pattern of incidents and engine fires involving the N57 in police vehicles, they reported their concerns to parent company BMW AG in Germany. Engineers at BMW's factory in Steyr, Austria, carried out tests on seven engines and found that the cause of the fault was poor lubrication as a result of ageing and degrading engine oil. BMW AG instructed BMW UK to advise police forces to upgrade the type of oil used in the engines to 5w30 and to shorten the oil change intervals to no longer than 10, 000 miles. However, BMW UK passed this on through the voluntary National Association of Police Fleet Managers of which Cumbria Police is not a member.
