It’s an electrical storm
Regarding Matt Tomkins’ ‘Starting Handle’ column on ECUS (PC, Oct 18), he is right that the high cost of OE replacement ECUS can write-off otherwise perfectly serviceable modern classics.
However, I have found that there are a number of firms now that will repair or exchange ECUS for a reasonable cost. My daughter’s Focus MKI was suffering from the very common issue of the instrument cluster intermittently going haywire and all the dials dropping to zero with various warning lights coming on. The cluster is an ECU in itself on the Focus, with everything connected on a CAN bus, but most issues are caused by dry solder joints or simple components like capacitors or resistors failing.
I sent it to a firm called ECU Testing who rebuilt it and sent it back for £80+ VAT, guaranteed for as long as I keep the car.
Dodgy ECUS are becoming common.
