Valtra t174 lack of power

[traadilooar]

Any one run a t174 versu and noticed a lack of power?
Can't find anything with the laptop, but the baler kills it and is struggling on the plough (which it didn't used to)
Bit of a nuisance as it's a great tractor

Fuel filters and system ok?

Air filter ok?

Does it have a DPF?

Check boost hoses and intercooler for splits.

All meant to be sound

Get your fingers on the turbo and check it isn't seized.

Fairly new, what does dealer think?
Under warranty still ?

 

[Jon]

AD blue sensors can be a pain,this might de rate engine ?

Turbo boost diaphragm?

400 hours,
Nothing untoward showing up on laptop, download ed engine logs and sent to agco, we will find what it is just wondered if someone else had found something similar and sorted it.

Turbo boost diaphragm?

Its CR !

 

[Flat 10]

Its CR !

Oh of course never thought of that!

Variable vane turbo actuator stuck?
Or would that be just to simple?
Boost pressure as expected when checked on the "laptop" ?

Apparently everything checks out

A visual check my a more senior member of staff might be advisable?

Get it on a dynamometer before you take the pistons out, replace the ecu, delete the ad blue and trade it in for a fendt.

We don't have things like either of them over here!!

Went through exactly the same problem a few weeks ago on a T4 series. Laptop showed up with no faults. Turned out to be the primary fuel filter ( the one close to the cab ) It's on the suction side of the fuel delivery and the o ring on the filter was a little deformed. Replaced the filter ( special tool required ) and power back to normal. Remove filter and check o ring or just replace
