massey 6716s tier 5 low on power

[ycymro]

as mentioned above our 6716s 20 plate has all of a sudden lost power, she'll die down to 500rpm on the shaft from 1000rpm running a power harrow. she'll have had complete set of filters about 150hrs ago, and she's had a complete set again since the issue occurred. there's no error codes at all.

has anyone else come across this before? could it be ad-blue related?

There will be error codes set if it's going into derate - unless it's been remapped by a flash&dash where the fault tables are often wiped.

Tract of is as standard as out of the factory. 3500hrs

Has it been on a dyno?
Any other machines running off the same fuel supply having issues?
Will it run with the fuel cap loose/off?
When it pulls the engine down, is it just under a lot of load?

Yes , had a Claas Ares De Rating under load .No error codes but was faulty wiring from Injector pump to ECU.
Could be sludge/bug in tank.
If mechanical lift pump , could be worn Tringle rod

Waiting for it go on dyno.
3 other tractors and a handler running on the same fuel with no problems.
Haven't tried the fuel cap, doesn't need to be under load, just the tractor alone is enough to pull her down

It could easily be something daft like debris in the fuel tank getting picked up on the suction tube then falling off

He would have low rail pressure faults.
