Hang about, the reason he chose the garage he did was because it had a large "Nissan" sign on it and boasts of the quality of the training of their technicians then Id certainly make them aware - this isnt just bad service, this is a misdiagnosis that has cost a Nissan customer time and money. I dont doubt that you wont receive payment direct from Nissan UK, but when one of their own franchisees repeatedly misdiagnosis a car and then gets very awkward I think a complaint to head office is definitely worth a punt, you may find they suddenly become a lot easier to deal with. I really would like to believe that would be the case, but you just know that all Nissan Customer Services would do is punt that back to the dealer and wash their hands of any responsibility. Sorry. Totally agree Colin. As most of us know, Nissan will just direct the customer back to the dealer. Sad but true.

Nissan UK will not take any action on your behalf. Your contract is with the garage that sold you the car and also with the garage that tried to fix it. If they are the same garage so much the better. Save your energy as you will only get more frustrated than you are at the moment. Get an informed diagnoses from elsewhere so that you know what you are up against The waiting game that you are playing is only depriving you of the use of your car which will probably just be parked up in the garage car lot somewhere. Good luck. Alex.

You will have to ask Torqen for an informed reply, as the image may be generic.

Thanks Stu, However the OP already has pm'd me, but has failed to send over the payment that he agreed to. If any one wants to jump in, feel free:

Could just be a traction issue caused by your style of driving. Pull the codes and report back

Is your car a JDM import or UK car ?

IMHO standard copper plugs are false economy on the 350Z whether DE or HR. As well as all the other arguments about which is the better plug regarding performance etc. etc. the Iridium will give you around 5 times as much time/ mileage than the copper. Copper will require changing every year or 12,000 miles Iridium should last you circa 5 years or 60,000 miles. If you have to pay a garage to swop out the plugs, they will charge you North of £100.00 each time. Do the maths. I rest my case:

Is that not £19.50 each for the HR ?

Get a code reader that is compatible with your car.

Well done.

PM sent.

I use the same map on my R35 for Shell and Tesco. You are paying extra for the Shell branding.

Speak to your Uprev tuner.

The HR model does experience similar issues and can be sorted with an Uprev.

That's Vincent's car and it is usually hovering in the back ground.

I would remove the spacers, K&Ns and Rays and MPSS s if you have the original wheels and tyres to go back on, if you decide to P/X

Thanks Alex - I assume to turn off the sensors is a remap (the car had an uprev, so presume I still have the license for a return visit)? Cheers, Howard Yes mate, Uprev.

The mpss will have the longevity but probably not £170.00 worth of extra miles, however mpss would still get my vote due to all the other pros.

Thanks Alex. What are O2 simulators? Are the O2 sensors not required at all with HFCs? Simulators is just the fancy name for spacers. O2 sensors can be turned off for all models of VQ35DE 350s
