Cars belong to our police force. Seems engine oil dilution is the cause.
Years ago you could run your diesel Land Rover for long periods in a stationary mode without detriment. The handbook had a chart telling you how many hours you could do this before changing the oil. Perhaps BMW should have it in the handbook for these vehicles. Fancy cars, fancy oil, but you still need to do the basics. https://www.msn.com/en-ie/news/other/almos...&ei=11 1982 88" 2.25 diesel 1992 110 200tdi csw -Zikali 2008 110 2.4 tdci csw-Zulu 2011 110 2.4 tdci csw-Masai |

had been a known issue with "fast response" vehicles for years and had had some very tragic circumstances......

What, so if you leave the engine idling for too long the vehicle can set on fire?

Like many modern vehicles they are designed as a cash cow for Corporates and
 actually being useable…..
Most ‘fast response’ uses on the UK now are actually Volvo SUV, etc as BMW seemed to actively sabotage their own success and then failed to rectify the potential fatal fault meaning no one has any trust in them |

Only if the driver hasn’t subscribed to allow the heated seats and steering wheel option…..  |

This is actually quite an old story and clearly it's taken a while for the Garda to get the message from the police over here.
The "problem" is that police vehicle have to be left running for long periods on tickover because the electrical systems including lighting, computer systems, dataloggers, and communications packs are too power hungry to run off the battery alone. The N57 engine, very much like JLR's TDV6, has a "fragile" lubrication system which is susceptible to dilution problems and apparently if you make an immediate transition from a long period of tickover to high-speed, high-demand driving it is likely to result in catastrophic engine failure which usually results in a vehicle fire as extremely hot parts and fluids are ejected. In January 2022 PC Nick Dumphreys was killed in Cumbria when the engine of his X5 failed leading to a high-speed crash and vehicle fire. At the inquest it was revealed that over the preceding four years there had been more than 60 instances per year of similar failures with police N57 engines, leading (rightly in my opinion) to outrage that nothing had been done to mitigate what was undoubtedly a very real and very lethal problem. The coroner issued a "Regulation 28 Notice" requiring a response from the police setting out the action being taken to address the problem, and I believe that all UK police forces have now stopped using N57-powered vehicles for frontline duties. End-of-life N57-powered police vehicles (certainly those "red-flagged") are no longer sold at auction as before but are now destroyed. BMW has always maintained that there is no problem with this engine in normal civilian use, and I am not aware of any reports of similar failures outside of the police service. Indeed there are many people in motoring circles who will argue that the BMW N57 engine is one of the "best" modern common-rail diesel engines ever manufactured. There are certainly fewer reported problems with the N57 than there are with JLR's TDV6 or Ingenium engines. |
