Suspect it's slow...

Just a thought you haven't got a flat spot on the turbo.

KLR Automotive at South Windsor 02 4577-5010

Is 13.1 l/100 kms high for a Td5?

Thanks for the input guys.
I'll have a look at the hoses.

My D2 is stock.
Not bars, no roof racks, small AT tyres, no engine mods (as far as I am aware/can see), etc.
In that context I think the fuel usage is too high. I don't necessarily expect to get the best results (some reporting 10L/100km, or less), but seems like it could be better.

It’s getting up there.... i’ve averaged 11.4l/100 over the last 39 consecutive fuel fills. Lowest was 10.9 highest was 12.1. And before I put the roofbars on I was averaging 10.1 ....

Around town (City), on the highway or average?

I get 11.5 to 12's on the highway at a good clip, 13's is hills & gravel off/on the throttle type stuff for mine & I haven't got a clue in cities.

Very much so!

I’d like to see it on a diagnostic (Nanocom etc) for some MAF readings.

Also, some free and easy checks:
Bypass WGM direct to turbo
Check Wastegate can actuate freely.

Update: wastegate seemed to move freely, so tried the bypass. This seems to have made a difference. Of course the misfire/flat spot is still there around 2200-2300rpm, but otherwise it seems to be turning over with a lot less throttle input. Was only a short drive, but I am feeling optimistic.

So next question is - can I continue to run it like this or should I replace the modulator?

(The other next question is regarding the misfire, but I am thinking that would require some more complex Dx...)

165,000ks since new, possibly a soccer mum or elderly previous owner and might need a good flogging for a blowout.
Do a stall test to see how the tranny is going.

The modulator diverts exhaust around the turbo to limit the boost pressure. Sounds like yours was always diverting at least something.
If the boost gets too high, the motor will go into a "limp" mode where you lose quite a bit of power. Quite unnerving when your overtaking.
I'd be replacing the modulator and trying to get it right, it's not that difficult to do your self.
