Tachometer / RPM problem ???

4r3s · 03-08-2010, 02:21 PM

2009 AT and no garage. I feel like it might be related to sitting outside in the cold over night but I have no way to confirm this as I just got the car in January and its only now just starting to warm up a bit here. I will def post back more info from the dealer when it comes.

frankster · 03-10-2010, 03:48 AM

@4r3s: I do have a garage (+7 degree C minimum) but the problem still exits. I made a clip with my phone today, alas no chance to post it here (I dont know how to *cough*).
When do you plan to take the car to the dealer?

I second that motion!

Im taking it in this friday, first oil change! the car hasnt showed this issue all week so far so I have a feeling this may be a multiple trip to the dealer to get it fixed...

frankster · 03-11-2010, 03:22 AM

Well, I'm curious to see what the reason is/was. Mine did it again today...

Hopefully it's not a multiple trip for you (and me) to fix it! I'll keep my fingers crossed.

yep just as I suspected. They couldnt recreate the problem and there were no error codes in the computer.

frankster - does your car only do this when it sits overnight and on the first start up of the morning?

Yes, only after a longer period of standing still. Last time it was after 8 hours standing on a parking lot. Use your phone-camera to make a short movieclip of the faulty behaviour of our diabolic needles

. I made 2 clips and I'm taking the car to the dealer tomorrow, so I can show them at last what the problem is - and I have an evidence.

Not good to hear that there are no errorcodes generated - it's difficult than to specify what exactly the problem is. ;-(

I wonder if our car has an electronical or a technical tachometer. That would be 2 completely different kind of problem.

Is your car new? (Don't remember if I asked that before...) Mine is, so I will push the dealer gently to a solution...

4r3s · 03-14-2010, 10:13 AM

its a 2009 made in march so its a year old but I just got it in january 2010 and only have 2k miles on it so I think that qualifies as new.

Vegitto-kun · 03-14-2010, 10:53 AM

sometimes if I start up and im in P the revs keep moving around the 1000 rpm mark just twitching up and down. it is weird

frankster · 03-14-2010, 01:32 PM

Yes, it'd call that new, too.

@vegitto: When the erratic behaviour occurs, it's like you describe, the needle is moving up and down instead of pointing to the exact value. Have an eye on it..!

frankster · 03-15-2010, 12:52 PM

Ok, I'm back from the dealer.

Like 4r3s they didn't get an errorcode. They tried and tested as provided in the TSB etc. No real progress.

ECM has been reflashed/updated. Formerly my brightness controls on the combi instrument didn't work correctly (I think), because only 2 steps of brightness were provided: brighter and darker. Now I have a ruler with which I can fine adjust the brightness in app. 10-15 steps. In addition, the navi has not only the dark and bright map for day and night, but an auto-adjust feature that I definately didn't had before. Depending on how much light is exposed to the navi-surface the screen brightness adjusts itself. Great thing!

So, at least something HAS changed...

Ok, only time will tell if the original error is solved - I just need to test it a couple of days (or weeks). I keep contact with my dealer, he want's to know if the error has gone or if it still persists. A case is created therefore with Nissan Germany.

I'll keep you informed, too...

frankster · 03-19-2010, 03:20 PM

Well, a couple of days passed now and what can I say?

Problem has gone!!!

ECM reflash/update seems so have solved the problem completely!

frankster · 11-30-2010, 09:30 AM

Ok, a couple of month later...and the problem is back again!

It really seems to be a weather-related problem, because it occurs only if the car has been on a parking lot outside, never if it has been in the garage over night.
A problem-ticket is opened at Nissan (global), so if anyone else has this problem, feel free to join the club!

If any news , I'll post them here...

frankster · 12-04-2010, 11:26 AM

News update!
Since I called Nissan customer support as well as activated my local Nissan dealer, I got a call from Nissan: my combination meter is about to get swapped to a new one... it's already ordered.

Later...

frankster · 12-10-2010, 05:12 AM

Combination meter has been swapped, everything 's fine since then...

The vehicle miles traveled can't be reprogrammed, so the reading will begin at 0 again. The values will be taken into the scheduled maintenance papers/documents belonging to the car.

I'll post changes.
