    Posted: 28áFebá2015 at 7:06pm
Hi, I've got an intermittent fault on my 1.6 dci.
The fault mentions something in the EGR circuit is stuck or stiff so I thought I'd take out my EGR valve to make sure its not caked in soot. It was a bit so I cleaned it up and refitted it, its certainly not stiff to operate.
Looking into it, the 1.6 dci is quite a complicated engine with high and low pressure EGR systems. This valve works on the high side like normal EGR, the low pressure system isánot necessary andájust something else to go wrong in my opinion.
Here's a pic of the valve before I cleaned it.

And if you're interested in how the valve works here's what's inside. The small silver cog is the motor which turns the big black one which works on a helical drive to open the valve and let exhaust gas through into the inlet manifold.

Anyway, the point of this post was to see if anyone has had or knows what could cause P1485 to keep appearing randomly. It only ever happens on a crank and can be cold or hot.

Sorry for the long post but thought it might be interesting.

Thanks.

Can't help I'm afraid - petrolhead.

But if you're in Denham Bucks, my first house was in Higher Denham, up near the golf course - nice

Well I've looked & looked & I can't find that code anywhere.
I agree that that engine is a bit to 'over designed' some parts unnecessary. Good luck.
Where exactly does that code flash up. I'm a bit new to Nissan.

Sorry, doing too many things at the same time! Code is P1485.
It doesnt flash up, I've got a diagnostic tool I plug in.

Interesting! Thanks for sharing the photos! P1485 DTC indicates LOW PRESSURE EGR VOLUME CONTROL VALVE. I can't upload the file for you as MODs has not enabled file sharing option on the forum. Sends me your email if you want it.

Oh no! The low pressure side is more complicated and hard to get to. I'll send you a PM with my email. Much appreciated, thanks.

The link won't download for me.

Do you have a photo of where in the engine bay the EGR is located, or even a guide on removing it.

My QQ+2 has the same issue 1.6
