Thomas alone in the Carparkwendy:  when I bring Thomas in for his new tyres I’d like you to upgrade the software aswell – but I don’t think I should pay for the software update

Service engineer: (disarming giggles) Good luck! You’re booked in

Diesel Particle Filter Malfunction (part 2)

ParkedDuring Thomas’ annual service the battery was disconnected forcing his onboard computer to reboot. After reboot the Diesel Particle Filter malfunction warning still showed.

The mechanic said the filter looked ok. The nice chap at the Mini Dealership explained that the software might be malfunctioning and would cost me £90 to upgrade.

£90 for a software update!

What?! Software malfunctioning? Software not doing what it was designed to do? That sounds like a programming bug to me, a design fault. Software doesn’t suffer from ‘wear and tear’ like mechanical components. It sounds like Mini manufacturers, BMW, are passing on the cost of fixing their poor original workmanship to their customers! Atrocious. Most software providers release free fixes for software bugs. Hmmmmm…..

An internet search suggested that driving above 40 mph consistently for 10 minutes on a regular basis should burn-off the diesel particles and remove any mechanical problem – if one actually exists. There were lots of discussion forums talking about the warning light showing when there was no malfuntion on BMW cars. Consistent with an actual software design fault.

I changed my driving pattern to include regular periods of driving over 40mph for 10 minutes. Bye Bye to beautiful back-road Oxfordshire. The warning sign still showed. Sigh.

Time to re-visit those lovely chaps at MiniCooper Reading…
