Hi
I wasn't actually charged for the reset as the mechanic who services my cars usually does the reset as part of the service. The problem arose because he didn't think he'd got the Chevrolet option on his Autel diagnostic machine, so didn't reset it at the time of the service. My oil service/reset warning came on a few weeks after the actual service, with the resulting DPF light, turbo underboost code, and limp mode problems.
It was only after reading up on the problem on here and other places that I found out that it can be reset on an Autel diagnostics machine via the GM/Vauxhall Astra J option, so I took the car back to him with the info on what he needed to do. It actually came up with 'Chevrolet Cruze?' along with the VIN on his screen, which he then confirmed on screen. It's quite a basic diagnostic machine, so even back street garages should be able reset it. Whoever resets it will probably charge for doing it if they haven't serviced it, but without doing so, it'll be a dog to drive and the DPF won't regenerate. His Autel machine cost ÂŁ3k, but those at ÂŁ120 on ebay etc are also apparently able to reset it.
Regards
