had to same problem with mine on tuesday -7 left it running for half an hr to warm up and jumped in and light was on . Tryed driving it more harder than normal but light still on few days later . ie today mine done 70000 miles 65 plate. in the end my pal told to disconnect batteys for couple of hrs . to reset itself ,connected it back up no light since and done about 60 miles today since , driving ok. mib just luck but worth a try. might not work on yours but never no.Our 2015 hiux. 3.0 engine is in for its mot.
They can't put engine management light out. It's the dpf filter putting on they say.
I've suggested the usual pikey farmers solution like removing the bulb and putting black tape over light.
Anyone deleted it or any other solutions?
