Battery Drain

[IDH]

The battery drains if Don’t use the car for a couple of days. I recently notice there is a little red light on the instrument panel that lit up when the ignition is switched off.Anybody know what’s causing this please.

Is it a flashing red light? That's the immobiliser. That's the only light you should see on the instrument panel when the ignition is off.
Can't help with your battery drain. Have a look for user @DomP182 and his posts. You might find some helpful information there.

No it’s not flashing, but on continuous but very faintly.I only noticed it the other night after it got dark.

So it never flashes? What does it do when the ignition is off and you lock the car?
Ive never heard of the light staying on continously before.
Maybe you could get a picture or video if it's visible enough.
How old is the car battery?

Having said that the new battery isn’t on yet, I’ve no idea how old the existing one is.I had it tested a couple of years ago and it was fine ( just a bad connection.

I'd try the new battery on the car first. It could just be something as simple as an old battery not holding enough charge and this cold weather will be affecting it even more.

But that wouldn’t solve the light problem would it ?

Could it be a bad connection on the immobiliser causing it

Or even need replacing

It might do. Like I said before. I've never heard of the immobiliser light staying on continously.
Having said that. My 182 died on a supermarket car park. There was no indication there was a problem with the battery, it was the original battery though and 8 years old. It had been starting OK and driving OK.
He did mention something about the immobiliser light if it stayed on continously. Anyway. I fitted a new battery and everything was good again.
Like I said before. That would be the first thing I did, especially if I had a new battery ready to fit.

Good luck. Hopefully the new battery will sort out your problem.

Definitely fully charge your battery and do a parasitic drain test with a multimeter

Thank you will do

Interior light and head unit are common causes

No it’s not that,looks like a short on the anti theft unit as the red light is showing m.
