Qashqai hesitation in 6th Gear

STForSale

Hi All,
Car is a facelift qashqai 1.5 dci.
About a month ago the missus noticed the car "pulling" at motorway speed.
Was serious enough that she took it straight to a nissan dealer.
He ran a full diagnostic and found nothing, took it for a drive, said that car was fine but the wife insisted there was a problem and he continued to check.

Turns out the air filter was completley clogged and he replaced it.
On the return journey the car was still pulling but was less prevelant.

Since then I've taken it for a spin and do notice at motorway speed there is a slight hesitation, revs don't seem to drop, and then it goes again.

Car has been fully serviced since incident but problem is still occuring.
Booking it back into garage today but would like an idea on what the problem might be

Thanks guys.

Could have something to do with the diesel particulate filter. If you have a look in the handbook you can read about these , they get clogged every now and then .

Thanks, no dpf warning light on dash and car gets regular enough long drives that should regenerate....

Worth adding that there appears to be a whining noise also

Turbo on the way out? Although that would make it down in power in all gears.

Turned out to be an intercooler pipe and was replace under warranty.
Cheers guys!
