What the car has quietly logged over a Croydon year
Driving in and out of the Old Town means the A232 flyover and Duppas Hill Road, and the queues at the Lombard roundabout and Thornton Heath Pond are a daily feature. That sort of use generates the kind of faults modern cars record and never mention: a lazy oxygen sensor, an incomplete particulate filter regeneration, a misfire counter ticking up on one cylinder, a battery that has dropped below the threshold the stop-start system wants.
A full service includes a fault code scan across the car's control modules, so those stored and pending codes come out on your report rather than waiting to become a warning light on the way to Gatwick. It is one of the main things that separates the annual service from an oil change. Alongside it we test the battery and charging output and check the coolant strength, both of which standing traffic works harder than open road does.
The physical work is the usual annual list done properly: engine oil and an OE or matching-quality oil filter, a new air filter matched to the airbox, a cabin filter of the type the car was built with, then all four wheels off so pad and disc thickness can be measured and recorded. The brake fluid is tested for moisture. The car gets a road test before it comes back to you, which on a Croydon car usually means a run that includes some genuine queueing.
Keeping an unbroken annual record is worth more here than people think, given how many cars in the borough change hands with ULEZ compliance on the buyer's mind. Everything we find is quoted in writing first, repairs carry a 3-month workmanship guarantee, and the drive over is around fifteen minutes to Hackbridge, or we can collect from Croydon. Either way you will know the price before we start.
