A 20-minute motorway run at 50–60 mph cleared the DPF light

DPF light came on twice this month. I mostly do 4-mile school runs. Dealer wants £180 for a forced regen. Is it worth it, or will a long motorway run clear it?

(Seeded test thread.)

Also check the oil level. The 2.2d dilutes its oil with diesel during failed regens and the level creeps up.

Did the motorway run: light went out after 18 minutes. Thanks both.

A 20-minute run at 50–60 mph in 5th usually lets it regen on its own. If the light stays on after that, get the soot level read first: a forced regen above about 85% loading isn’t safe.
