Question 1

Why does a DPF block up for drivers in Renfrew?

Accepted Answer

Frequent short journeys around Renfrew, interrupted regenerations, faulty sensors, EGR problems and incorrect engine oil are the usual culprits. Cars that never get a proper hot run never complete a regeneration, so the soot builds up.

Question 2

Will my car still pass an MOT after DPF removal in Renfrew?

Accepted Answer

Yes. A DPF is required for an MOT but it isn't visible to the inspector — the only way to confirm removal is to dismantle the exhaust, which the MOT station won't do. We'll talk you through the detail at your Renfrew appointment.
