406 Coupe 210

Hi,

before starting the engine I can hear
a very soft continuous warning signal,
which vanishes after a short while.

No signal lamp or other abnormal display is shown.

Any idea?

TIA
Joachim Engel.

Fuel-pump?

It's normal. Building up pressure for the injection.

Hi Norman,

sorry, I was wrong.
It is short after starting, when the engine
has idle speed.

Fuel-pump?

May be. It's like "meep-meep ... meep-meep ...".

Probably I don't have to worry,
if there is no audible warning signal
without any visual display.

Kind regards
Joachim Engel.

The climate control makes that kind of noise - I think it's the servo motors adjusting things to suit whatever setting you have selected.

Anti-lock-brakes (ABS) pump maybe? It makes some funny noise on my parents car.

May be. It's like "meep-meep ... meep-meep ...".

The fuel-pump sound appears definitely before starting the engine. It's a continous humming. 'Meep-meep' sounds more like servo motors as posted in the other reply.

Bye

I will watch this with different settings.
