Unknown beeping - help!!

[Sandie]

is there any indication on your dash screen? - seatbelts, open doors?

No dash indication that I have seen, but it's entirely possible that something has flashed up and I wasn't quick enough to catch what it was.

One of our sprinters had a beep, that turned out to be the rear fog lamp if it wasn't put in the off position even though all was switched off with the key.

I haven't got a step. It's an Adria Matrix 590SG, but thanks for the suggestion.

Check your brake fluid level.

Alarm or Tracker backup battery on its way out?

 

[Ridgeway]

I appreciate that this is a while after your original query, but could your mystery beep be related to the immobiliser? My 2002 Chausson used to emit a high pitched beep when the immobiliser was activated /deactivated.
I came across your post as I have a mystery beep on my newly-purchased 2016 Adria. It only happens when moving, isn't accompanied by any warning lights as far as I can tell, and is definitely in the cab. I can't correlate it to anything...most annoying!

We've had a similar issue on our Laika with a buzzing noise that came from the cab area, inside the dash. It only ever comes on when it's raining and the road is very wet, the next day when it's dry the noise is gone.....

Never been able to trace it and after 5yrs it still crops up.

Guess we'll never find the answer to this one......

The bleeper for my Tech Tower fridge door open alarm is on the circuit board at the back and is louder outside than in. There's no visible door switch on mine so it's an embedded magnetic switch. If the door is closed normally the alarm sounds. A slight extra push silences it.

Has someone set the speed limit warning? I have mine set at 33 so it sounds every time I exceed that that speed. Beeps just the once as I accelerate.

 

[Sandie]

Thanks, folks. A number of things to check today, then!

Are your electric distribution box, charger etc in the garage? In my van the charger is also responsible for 12 volt distribution when on a hook up. You say it does not beep when you are travelling so its then reliant on the split charge relay from the cab battery & alternator which is OK. Might this be an indication of a fault with the charger/12 volt distribution with the beep warning of the problem? Have you checked all the fuses on the distribution box and also checked the fuses in your charger?

Just a thought and trying to help!

We had a 'chirp' which came and went it. You have a garage, get someone to press in the black sensor button with the door open and see if that stops it. Can be caused by slight misalignment of the door, we temporarily fixed ours by taping a milk container top in the correct area to give the pressure needed. still there over a year later J never does things in a hurry.

Thanks. You misread my post, I think. It only happens when moving.....
It's doesn'r really sound like any warning beep I've heard before on any vehicle - more of a high-pitched brief electronic whistle. The only thing I've heard that's similar was the noise my old van made when the immobiliser was arming or disarming.

Could be the turbo whining?

Thanks for the suggestion. I've never heard a turbo whine, so I'm in teh dark on that, but it's a very brief noise- less than a second, I'd say. Wouldn't a turbo whine persist for a while?

No not always we have a Fiat Panda with a 1.3 turbo diesel a smaller version of its big brother and we occasionally get a faint whine

@Sandie so what was it?

Yes

We had a whistling internittent noise that I finally traced to the interface unit for the towbar wiring. Had it replaced, whistle gone.

 

[Sandie]

@Sandie so what was it?

Still not traced it, BUT it occurred yesterday. Engine was off, m/h parked, on electric hook-up. Facilities control panel was switched off, as was the Truma control panel and all appliances. It's a mystery.

I'm still at a loss. It has now occurred whilst parked up, engine off, on hook-up, 12V control panel off etc. So, this interface unit you mention...is that something that is fitted only when you have a towbar, or is it something that is part of the base vehicle electronics. In other words, would I have one?

Cambus wiring kit for towbars ---

I had similar occasional beep that was eventually traced to the towbar canbus unit. You would only have one if you have a towbar though, or if someone has fitted electrics for one. I did just remove the power supply to it, before replacing the unit, not that I use the towbar though.

 

[TerryL]

Our "noise" became apparent in the middle of the night on a Welsh hillside, that's when I eventually traced it to the towbar unit. As Lanyandy, I disconnected the power cable and it stopped and eventually had the towbar re-wired.

 

[Wickolad]

View attachment 289371 traced to the towbar canbus unit.

This actually started screeching as I washed back of motorhome and was rinsing with hosepipe. Found the unit located behind the rear light cluster. Moisture had gotten to the unit on this occasion but a dodgy connection could do likewise.
