Technical LED Display

[Cliffh]

Good day all,
I bought my 2012 Panda Young 1.2 second hand but it never came with the user manual.
Lately when I start up the engine somehow it resets all the LED units to zero.
This does not happen every time I start up.
Only the odometer is unaffected but everything else resets to zero.
(Trip meter A & B, fuel consumption etc)
Any thoughts would be appreciated.

battery dropping below 6v while cranking

worn out battery is most likely


poor charging


High resistance in a power, ground lead or corroded battery leads.


I would check the battery First. If you don't have a volt meter most motor factors, garages here in the UK will check it free of charge.

A cheap test meter wont have the high sample rate of professional equipment but should be good enough for checking the battery voltage while engine is cranking.

I recently fitted one of these to my wife's 1.2

It's at least £30 cheaper than Halfords and arrived the next day very well packaged.

Another vote for battery.

If it's the original, just replace it - it isn't even worth trying to test it.

A big thanks to all you guys for suggesting the battery.
The tester showed "Bad, replace battery" straight away.
About 8 months ago my fuel gauge started playing up as well as the needle was jumping around. The FIAT dealership wanted to charge me R11,000.00 to replace the sensor in the tank. Thank goodness I never had this done as I think the battery could also have been the problem.

If it does turn out the sender is faulty the parts should not cost silly money. (Yes I do know you are not in UK just using a local example)

Glad you got it sorted. Mine also reset to 0 three times this winter, after struggling to start from cold.

We've only been doing (very) infrequent (very) short journeys, usually in the dark, so I guess every trip was draining the battery more than it could recover.

I've charged the battery up and it's been fine since. Still, ours is quite an elderly 40Ah battery so this could be the first sign its days are numbered.

Thanks Dave.
Since replacing the battery all problems are sorted.
Can't believe that the battery was 9 years old before packing up.
(Still started well though)

Still started well though

I had a Yamaha 900 bike that turned over fine but refused to start yet when I put a meter on it the voltage was down around 7 volts. At least two cells were awol.

The starter sounded little slow but nothing obvious. The battery was buried under body work but it stated immediately with jump leads and a long screwdriver (to reach the positive terminal). There was not enough contact area to give much extra oomph, but I guess the voltage held up enough to light the electronics.

At the opposite extreme a 12V VW boxer engine with a six volt starter turned over at an amazing rate. Double the volts gave double the starter power.

Once the weather warms up it will probably solder on until the next cold weather

Heh, that's what I'm hoping I've added a new battery to my growing list of things I'm probably going to need in the next year or so.

had the same issue, testing battery showed 35% starting capability. replaced with new battery and problem solved.
