❓ Frequently Asked Questions

► Is Four Marks driving bad for a petrol particulate filter?

Most driving in and around Four Marks is short-distance — the school run, local errands and trips to Alton. Petrol particulate filters rely on passive regeneration during longer, higher-load driving. Without it, soot accumulates and back-pressure rises until the engine flags a fault.

► Does a GPF warning light mean an MOT fail?

It does. Since the MOT includes a warning-light check, an illuminated EML or GPF light is a straight fail regardless of how the car drives. Cleaning is the cheaper fix by a wide margin.

► What happens during a GPF clean in Four Marks?

We plug in, read live sensor data and stored fault codes, clean the filter in place, then re-run diagnostics to confirm the result. The whole visit is usually 60–90 minutes.
