I have a 2011 Diesel Roomster which I recently bought for £2.5k. It’s in reasonable condition – good tyres, brakes and a good runner. There’s a couple of minor scrapes which I can get fixed without breaking the bank. It has 99k on the clock, a fair amount of service history and 6 months MOT. It was only serviced around 4.5k ago, but that was 18 months ago so it’s done very low mileage since. I think it’s been stood for some time so I decided that a full service was the thing to do. My local garage fixed a couple of minor issues in the process. Otherwise they said she’s good to go. What worries me is that, looking through it’s service history, it had a fuel injector replaced not so long back and the garage who fixed it advised that the others were weak (whatever that means) and may fail. It’s starting up okay and running smoothly with no warning lights. My local garage has all the diagnostic kit and they didn’t report anything amiss. Am I worrying too much? I know that replacing fuel injectors can be expensive though I gather that refurbished units are an option. Any thoughts guys?
