Radio reception

is200 Newbie · December 1, 2016

I have had an issue with the radio reception for a few months now - a lot of interference even on the strongest reception of the channels. I also have an issue with the cd player not playing original CD's and DVD's

I changed the car Battery this week as the old one was losing charge - looks like it was the original Battery that was in the car.

I have now noticed that the radio reception is back to normal!!? Possibly co-incidence by changing the Battery but could a failing Battery cause interference? ALSO - when I was removing the old Battery, I needed to remove a plastic frame housing the Battery which had what looks like a suppressor attached to it (or something like it) I had to unplug this "suppressor" in order to get the plastic frame out so I could get the Battery out.

I put the new Battery in with the frame and re-connected the "suppressor" - could the action of unplugging and plugging back in this "suppressor" possibly have cleaned an "iffy" connection that was interfering with the radio signal?

I know the connector you mean. Been there myself.

I was unsure to its relevance at the time.... about 3 years ago.

I think someone said they thought it was a heat sensor of sorts.

But I could equally be way off the mark.

Good that you have radio back though.

Ah ha - heat sensor - I have seen that mentioned somewhere also. Makes sense to the reply on another post I made where owner experienced a hot Battery ... but doesn't explain no warning tho.

Anyway - tunes are back, albeit radio ... happy Christmas to me !!

Just a thought ..... but, ....... could that sensor also be a trigger for the 'Battery Low' warning on the dash.

Maybe it interprets heat sensed as a forewarning of a dying battery.

Just a wild gues

I would guess not. My Battery was too hot to touch yesterday with little spurts of boiling acid coming out of the top but I had no warning light on the dash. New Bosch Battery fitted and it sailed through the MOT today

I seem to remember reading a post on this forum a while back about a temperature sensor on the side of the Battery. Mine (if that's what it is) is located on the left hand side of the plastic cage that goes over the Battery - I guess it will sense heat from the Battery area but as well as that, thinking about it then there would be engine heat also.

hmmm - another gizmo to google to see what it does....
