SCR warning light

[Paddington]

My SCR warning light has been coming on for short periods on a DMax. Is the cat stuffed or do I need a good blast up the road ? Manual refers to an abnormality which isn't much help. Last few weeks with roads and traffic the engine has probably never been above 2000 rpm.

First job- give it a good run at 60-70mph. If no fix, call dealer

As above but keep in 4th to keep the revs up for a good 20 miles to get it hot enough to burn the soot off and let it do it's dpf regeneration cycle.

Take it to somebody who can do a forced regen, I got mine done and it is now doing 20 miles more between regens

The best way to get it hot is to pull a loaded trailer up a decent hill somewhere. Modern vehicles have so much power that when cruising at any legal speed, the engine really isn’t working very hard.

Would any garage with a scantool be able to do a forced regen ?

No. Need a higher end tool to do stationary regen

Heavy load of cattle in the IW and a run up the Corvedale to Telford and back, will sort it....

The light comes on after 5 minutes then goes out after say 10 minutes and a bit of welly. Think it's sorted but next day it's back again. Not used to these modern diesels.
