❓ Frequently Asked Questions

► Why do Thatcham drivers get blocked GPFs?

The A4 through Thatcham carries plenty of passing traffic, but most local trips are short runs into Thatcham or toward Newbury. These stop-start conditions prevent petrol GDI engines from reaching the sustained exhaust temperatures needed for the GPF to burn off trapped soot, so deposits build up over months until the filter restricts flow.

► Does a blocked GPF fail the MOT?

Yes — a lit GPF or engine management light is an automatic MOT failure. A professional clean usually costs £150–£350, well below the £800–£2,500+ needed for a replacement filter.

► How long does the GPF cleaning process take at my Thatcham address?

Most GPF cleans take 60–90 minutes on-site. We carry out a full OBD diagnostic first, clean the filter, then verify the result before we leave.
