Odometer / Mileage Display Resetting?

[C2WAK]

All,
My girlfriend has just recently bought a black 02 172. We have noticed that for some reason the odometer / mileage counter is resetting itself?
I have banged on the dash and checked if the button to reset it is sticking and it doesnt seem to be... I think it seems to happen when the car is cold? (could be a red herring though).
any ideas?
Ive never seen this before and ive had 2 172's of this same year.
Where should I look? or does this sound like a Renault jobby?
Thanks all
ChrisW

You mean banging the dash won't fix it?

If it was the battery, wouldnt it show in other areas of the car when starting etc etc???

Thanks

Depends, the trip computer has a memory, if it hasn't got enough power for the memory it will wipe it?!?!

Battery then it will be perfect, I had no other signs either.

As a few people above have said, battery. mine did the same and showed no other signs e.g started first time with no dim lights etc then one day battery was flat as a pancake. New battery fixed it though

 

[C2WAK]

Excellent, many thanks as always for your help guys...

had the same thing happen,seemed fine starting for months then battery went one day then sorted

Yeah defo battery, especially as your saying its worse when cold. Been in the same position

BEst way to tell if its the battery....turn on the ignition, wait for the fuel gauge needle to stop rising (best with a full tank) and then as you turn the key to start the engine, keep an eye on the needle. If it drops as you start it then rises up again its the battery.

Means the dash is losing power during start up because the battery is weak.

If you need a new dash i have one spare pm me if your interested.

 

[C2WAK]

I had my missus go to a local parts shop and have the battery tested, he said that there was nothing wrong with it???
Could it still be a dodgy battery thats just not showing up on Amp tests?
If its not the battery then its got to be wiring.. feck?

Battery will be fine under test, mine was but a new one will cure it resetting

 

[Terry172]

I noticed the same problem with my 172 and I changed the battery and it cured it

 

[Djw John]

Trust me its the battery.

How old is the current battery?

 

[C2WAK]

Trust me its the battery.

How old is the current battery?

The car is a 2002 and i dont suppose its ever been replaced. I know the car was standing for a long time outside the prev owners, thats why he sold it cause he worked on the cruise ships... maybe its damaged it. I will get her to replace the battery for it. Any ideas the best place to get a battery from? and how much?
oh and the car has done a little over 41k

 

[Djw John]

Batterys have a life expectancy of 5 years or so and letting them discharge through not being used does damage them.

Halfords calcium batterys are decent and come with a 4 year guarentee, dunno how much though, I got it on Trade discount

I'd bet genuine cash monies on you replacing the battery and the problem resolving.

Mines been doing this alot lately , only when it's cold though . If i set off quickly just after start up then all the lights on the dash come on for a couple of seconds , the low fuel light stays on even if there is a a quarter of a tank or more and everything resets itself to zero except for the total mileage . It's did it a few times last winter as well . The cars only just 2 years old so it sounds like a dash problem rather than a battery problem imo .

 

[davo172]

Trust me IT IS you battery !!

 

[nickl360]

Would a battery be at fault for the MPG, miles to next fill up, tripometer all reading blank?

I went to look at a car and that was what the readouts were like. Or is it because they've took the battery out and replaced it but not driven it anywhere?

 

[capturedbyjames]

Tell tale sign this was happening to me was when my CDs started ejecting when I started her up... thats how i monitor it!

 

[davo172]

Lead head you need to drive the car for about a mile before any readings show on computer but if it is resseting when you start it up it is the battery although it wont turn over slowly or show any other signs

 

[MRBILLYUK]

Trust me IT IS you battery !!

Trust me . It's not always the battery . My batterys fine , i've checked it numerous times . It's holding a charge . If the batterys the original and around 3 years old then i would accept that . But mines done this from being around 12 months old .

My battery was the same too mate ,checked and tested it loads of times, car never struggled to start or showed any signs of a battery problem started off as an occasional problem then became more frequent mine started doing it when car was about 18mths old . I thought same as you, it can't be battery but it is . If you notice it usually does it when car is cold or during cold weather, not every time you start it. I was also getting a faint clicking noise from behind the dash too. If you start it and it dosent reset switch it off put lights and stereo on for a bit then try it again if it resets then this is a good way to check if its battery.Mine even had good readings on tester during charge. Gotta be worth a try mate cheaper than a new dash
