Nissan QashQai Forums

Hi All

I bought a QashQai last April and it has been a brilliant car. In fact I've been singing its praises so much that perhaps I have jinxed it!

I was driving last week and noticed the car was more sluggish than usual at around 30 mph. It felt like the turbo wasn't kicking in properly. When I got it onto the motorway, I had my foot on the floor in 5th and couldn't get over 60 mph. This got worse when the motorway started to kick up hill.

I've put it into a friend of mine who is a mechanic and the following code is coming out of the Snap On code reader...

P1453 - Diesel Particulate Filter Differential Pressure Control Function

He has reset and regenerated the car and the problem went away on his drive home. Good as gold the following morning and it then came back on later the same day when he tried to drive again.

The symptom is accompanied by the loss of cruise control at the same time.

Has anyone seen this before or had any experience in what to do? The car has covered 43k and is used on a mix of long and short journeys but always goes on the motorway every day.

Any advice appreciated ladies and gents.

Thanks

Seems like you may be suffering from one of the 2 hoses that come from your dpf to the differential pressure sensor splitting, it's usually the black one ,, to see it you need a mirror or a borescope to look down the back of the engine and you should see if its split as it will be surrounded with soot

Hope this helps
Cheers

I have same issue, black hose appears to be the culprit, but no soot.

Hi All,

Just resurrecting this old thread as I have exactly the same issue on my 2014 1.5 j11 QQ. Also tried a resetting the code and regen / driving at 3k revs but engine light keeps coming back.

I am not comfortable under the bonnet but will see if i can borrow a mirror from the wife and find these two pipes and look for a crack (wish me luck as no idea where to start lol).

Just hoping it it something simple like this as don’t fancy a DPF bill before Xmas..

I'm in exactly same position
My nissan qashqai cut out on xsmas day. Had to be towed home.

The garage has replaced my pipe. Still not working so now looking at dfp

My mechanic changed the pipes and problem was fixed!

Good luck with your QQ Laura

I'm having a similar problem however my cruise control and speed limiter have stopped activating, I'm getting the same fault code p1453 as well as a p0380.
Can anyone suggest anything?

Thanks Al

So, I've had the pipes checked and there fine.

I've cleaned the egr valve and it's done nothing. Sometimes the issues just goes away until the next time I drive it so I'm thinking it's the turbo pressure sensor as it will hit 70 on the motorway, it takes a while to get there mind you.

But still no joy, it's almost like the turbo isn't working or kicking in hence my thinking it's the sensor.
