Date Posted: 02 Apr 2013 at 3:13pm
I have just bought a Nissan Primera 2.2 dci (2003). I have just fitted a suction control valve myself cleared the fault code and reset the EML and fuel pump. Started the car up for approx 10 mins which the car cut out. tried starting it again but was totally dead. Is there any advice on how to overcome this problem
Cheers.

Yes I appreciate that, but at least it was still going, if you put that one back it and it starts then you have a faulty new SCV, if it still won't start then we can eliminate the SCV and look else where. I take it you have no error codes and no NATs lights on and battery is strong and charged

I took the car into a nissan dealer and they advised me it was the svc the vault code came up p0089 and the EML was on. they were going to charge me £400 to do it. so i decided the cheaper version and do it myself.

Absolutely agree, no point paying vast sums to them on a simple operation
That fault code is normally associated with SCV. Did you change just the one valve?

Suction Control Valve replacement Save yourself a pile of cash by doing the following. This how to Is based on the Almera (N16 phase 2) 2.2DCI all other Nissan’s will have the same item but maybe slightly difference to replace due to different location etc. Symptoms Loss of power, erratic idle (more so when cold) boost spikes (loss of total power during overtake) If you contact Nissan and say the above they will probably say you need a new diesel pump but that’s not really true. What you do need it a new suction control valve, AKA fuel pressure regulator in the diesel pump. Tools Required 10mm spanner 6mm Allen key This how too will explain the process of replacing the suction control valve and how it will improve you DCI engine.1.Go to Nissan and get the valve(part no NA6860AW42B) it’s about £120+vat give or take | http://www.npoc.co.uk/forum/forum_posts.asp?TID=2866" rel="nofollow - best OEM P11 JAE 08&09 SB "he isn't human, he is a machine that never falters." | |

A link to that other post would have been enough, mate
those pics are from an Almera, which has only one SCV, if I'm not mistaken, where the P12 has two, as Timeshock said. Nissan4u.com at least lists 2.
Got a pic from your own pump and valve?

The older primera diesel(pre facelift) had two valves that would go faulty, the newer dci is the same block as the almera dci and xtrail and has the one main valve as per the guide. The problem with the electronic service manual is that its aimed at the first release of primera p12's and doesn't really cover the dci.

Hi,
My Almera 2.2 DCI is experiencing the same symptom’s.
I am going to have a go at doing it myself as it doesn't look too onerous a task however can I ask why the battery needs to stay off for at least 90 mins?
Cheers

battery disconnected is usually to reset the ecu or for other reason's. You know you can turn your light's on or press the brake pedal for 5 second's so and disconnect the battery to discharge any residual current left.

as mentioned above you need to reset the system, ecu etc once the SCV is swapped over, leaving the battery of for that time is the cheap way to do it, if you don't want to do that, just fit the part, drive over to Nissan, give em the £60 odd for 30 mins work and they'll reset it for you..

Thanks for the advice. Can I just confirm that by leaving the battery off for over 90mins once reconnected it will reset automatically or will I be required to do something else? Appreciated in advance

One last thing, should I got for a genuine Nissan part or go for a Denso one, which are slightly cheaper on eBay etc? As you might have guessed I'm new at this however where in the engine area is the suction control valve located? Once again many thanks

Chances are the Nissan part is produced by Denso. The SCV is on the back of the fuel pump. Back of the engine iirc.

Nice one. Although not counting my chickens to soon but I've done a ECU reset and since doing it the car seems to be running better, a possible fix?

Hi, guys, thanks for posting this tutorial, really greatly appreciated. Now, I've got myself a SCV to replace my existing one, which was giving me an error (P0089), but as I went to change, forgive my dumbness, I could not find the location. Would you, any of you experts on this, help me out, please? Regards, Borges

Looking at rear of the engine towards the top (pulley end) you see the diesel pump,then your looking for something being held by 2 allen bolts to the pump,that your scv.
Disconnect the battery for a while first.

Thank you very much for all your help, guys. God bless you for that. I've changed today morning, and, in all honesty, I thought that I wouldn't be able to finish. What a place to put that... Phew. Any way, I hope this will sort my P0089 problem. Kind regards, Borges
