Weird electrical problem, resets diplay

[oelhunden]

Hello,

the last two days I have experienced that when I stop the car, the cabinlight does not come on, and if I turn the key not ligts comes up on the display.

But I can start the car.

Then the ligths come on the display, but the clock is reset til 00:00.

The radio behaves like is has been disconnected, comes up with the "SAFE" message.

Like the battery has been disconnected.

It does not happen every time.

Any ideas ?

regards

dodgy earth connection?

I would start off by checking battery connections are tight and all fuses in the box on the side of the dash are fully home. I don't know if the fuses on top of battery are related to the circuits you mention, but I have seen posts on here before where they can cause problems.

Thank you for answers.

I will check the fuses tomorrow, the connections to battery are ok.

I am considering the battery itself.

The car is about 3,5 years old, so maybee it is time for a new battery....

Hello again,

there were no problems with the fuses.

But the central locking system is also acting weird.

It will not always close at the first time, but I can get locked by pushing a couple of times.

Like it does not have the power to lock it the first time.

I am still thinking about the battery, I have never had these problems and I have driven the car for 30000km, it has now turned 90000km.

I am driven 100km each day.

But the last 14 days I have been on vacation, and have rarely used the car, so I am thinking the battery have not been charged well enough, and when it is almost 4 years old....

I will see if I can get the battery checked before spending money on a new one.

I had the battery checked, and it showed no error, however, the VAG COM showed some errors related to the battery.

So I changed the battery and no errors since then.
