Dodgy Fuel Guages
 

I just had my 20K service and I have been told that both fuel senders need to be replaced as one of them is slightly out of specification.
That's why the last RH fuel LED wasn't working.

So those of you with the same problem you will be waiting a couple of weeks for new senders to arrive from Japan.

Exactly the same diagnosis as mine a few days ago. I'm on the waiting list now for both senders.

How much did the 20k cost? I've got 1000km to go. Also I've got bloody 2 lights out. Anyone got 3?

Bez did i think............1 of mine is out..........pos

The service cost the same as the 10k service $263.00, but thy didn't reset the service warning in the trip computer!

so its not just sulphur deposits. its the actual sender malfunctioning. so they actually have to be replaced.

I've got one out too. I might just call them and let them know before my 10K service to get it fixed.

The last 2 filled up 3 was out..., but after 10 mins of driving its back into two....and sometimes after a day (not much driving probably up 15km) the 2nd light lit up :shakes head:

I will pop in to dealer sometimes next week, hope they wont blame my mods for it!

'Sorry your car is too low which causes the fuel senders to malfunction as they only work at a certain height' :p wouldn't surprise me ahaha

nah you'll be right. I might pop in sooner than 10k too so I get the parts ordered in

I'm booked in for next wednesday to have my fuel senders and mats replaced and also once again the hatch opening problem has come back even with the new longer springs.

I filled up til it over-flowed just to make sure. Started the car and had 4 lights off!! Over the next day, I gradually went back - a light at a time - up to my original 1 light off.

I've got my 20k service due in the next few weeks. Would your advice be to let them check out the problem pre service so they have the parts ready or is it now a common enough problem for them to fix on the spot?

I called today and they said i have to bring it in

Dropped mine off this morning for the 10K and i too have mentioned the end two lights not working.
They just say we need to have a look, even made sure i filled the car up to the brim before i went in.

My final light came back on the other week when i put 98 octane in and after about 50km of driving. I'll see if the light comes back on tonight... I really want to avoid them having to replace the senders... i'm almost positive they'll screw something else up...

Any of you guys try techron or any other fuel system cleaner to try and fix the problem?

370z Reasons... i'm sad to hear that the new longer springs stuff up as well... if these new ones stuff up i'm gonna ask for like ten of them near the 3 year mark so that i can replace them as required after the warranty period.

My 2c is I've got the new springs but over time they seem to get 'weaker' as I'm starting to have latch catchin issues again :(

Exactly the same happened to me after the 10k service, I had to return the following week to get the service light reset.

I would like to know what they do to fix the hatch, I had the longer springs fitted only three weeks ago, and it appears to stick again on every initial operation. Once it has been opened it continues to pop up without a problem, it's just the first time you open the hatch.

I'd like the report that since last week when my final dot lit up after 50km of driving with 98 octane fuel, this week the last dot lit up from the beginning. I have conluded i've scraped off what ever was on the fuel sensors stopping the reading...

before you get the people drain the tank and look into it try techron for two consecutive refils and see how it goes... they're 13 bucks a bottle at caltex and they might save you from potential complications...

seems like Nissan has done a recall on dodgy fuel guages...which makes sense to me.

also I to have the boot not opening up on the first go, kinda annoying when holding something heavy.

Yeah but won't this just keep happening? We shouldn't be having to put in fuel treatment to get the guage to function correctly not to mention the extra costs involved. I'm leaning towards faulty guages or out of spec guages...

Well i picked up my car last night (10K service, $305), and the fuel senses have to be replaced. Two senses in the system, one part is in stock (or in aus already), the other has to come from japan (7-10 days).

I mentioned it seems to be a common issue after reading the forums, and I was told that it isnt happening to every vehicle because it is put down to a bad batch of parts from the maker in Japan. And that it could be happening to other japanese makes as well. The last bit seemed like they dont want it to sound like a Nissan problem.

Either way, under warranty, just glad these things happen early and not when i click over to 101xxx Ks and they charge full tilt.

It could, i'm back on 95 octane now, i'll keep the forum updated if the problem comes back. Have a feeling it's dirty fuel and most cars suffer from it but don't realise cause they've got analogue gauges.

Nah can't be mate, my girlfriends car is an 8th gen civic which has a digital display, we use exactly the same fuel and she's had her car for 3 years. Never had any kind of issues with the guage.

It's simply shotty sensors.. we need to get them replaced.

but i have no confidence in the nissan guys doing a good job... =( this procedure's gonna keep me awake at night...

lol I feel your pain.... their installation of my rear sensors is proof..... lol

So i tried to run my petrol down as low as possible (before ******** myself thinking the engine was gonna seize up hahaha but i had about 15km showing on the fuel guage...
Just filled it up completely with 95... it only took 60L in... (Its a 73L tank isnt it?!)
And when I went to drive off the last 3 lights werent even lit up!!
Definitely a sensor problem. Im gonna call the dealer and get the parts in before I take my car there for the 20,000 service. They usually are very good.

lol i've had mine at the trip computer showing **** and zero dots. I knew the car would make it cause of total kms travelled on the tank...

I filled up and there was 6L left in the tank =)

Yeah even when the trip says 0km left there is still between 5L and 10L in the tank. (maybe you all shouldn't know this...... lol)

Yeah i figured it was a nissan safe guard... but still once you find out this fact... back to square one... I will one day put 72L in the tank in one pump... else i have failed....

hahaha yeh i figured that was the case. most cars do the 'reserve fuel' sorta thing so i wasnt too worried...

but in saying that, i still fondly remember pushing dads BMW 325i across three lanes of traffic because it ran out of petrol at the set of lights opposite the petrol station... and his showed 24km left in the tank hahahah.

slightly off-topic but i feel as though this sucks petrol more then my 350z....

I've just run a tank full of Techron 5000 as suggested in the faults thread and it made some, but little difference. I now get all but the last LED light up but it's unreliable and flickers. I'm going to keep off Shell Vpower for a while and try BP Ultimate 98.

That reminds me to chase up Nissan for my replacement senders...it's been ages.

I reckon that's a sign that the techron is useful. Try one more tank run and maybe it'd clear off the last of the residue on the sender?

I've used BP Ult 98 since Day 1.

i used vortex 95 from day one, then moved to vortex 98

My service manager just called to say Nissan are producing 2nd gen senders to fix the issue and would I like to wait for these or get the original part replaced. The new models will be out in a few weeks. Im waiting.

you reckon a tsb will be issued?

man i hope they know what they're doing when they fix it... just looking under the car the other day... there are a lot of stuff they need to pull off before they get to the tank... =S.

Yep TSB for sure as it's a known issue now.

They have already had my car apart to inspect the senders a month ago with no issues. They may do it from the rear hatch area...not sure.

I had my fuel senders replaced and for now it seems to have fixed the problem. It's not fuel related, and basically ther is only 2 refineries in Oz that make all of the petrol so it won't make any difference what you put in it!

How's your car now? Still have all the fuel lights on with the new senders?

Whats confusing is my dealer just did more testing and have concluded that the issue is actually with the cluster and is ordering a replacement. A new cluster will also reset the Odometer which is a bit dodgy. He said this can't be adjusted.

Not sure if I want to bother with it now...
