Hello Qashqai Forums,

I recently took my car to the garage because of an engine warning light on the dashboard.
The mechanic connected his laptop, ran a diagnostic and cleared the warning.
He said I needed new glowplugs, sure no problem, fully understood.

But since then I've been hearing a strange computer type noise coming from under the dash, it could just be a coincidence.
It's not the radio, it reminds me vaguely of a computer modem, it's like beeping and bleeping.
The sound is intermittent, coming and going, with no discernable pattern.
I went back to the garage and he said "don't worry about it"
but the noise persists and is understandably annoying...

Does anyone have any ideas about what's wrong? Any help is appreciated.

Thanks very much.

I could only think of noises as likely AirCon stuff. Certainly a noisy Evaporator or perhaps fan control?

Thanks, Calnorth

That's definitely a good suggestion, I will make it when I go to the garage.

Thanks very much.

Not sure about the "beeping" sounds? But we had an annoying metal on metal "tinny" morse code type sound coming from behind the dash, mainly behind the climate control unit. Turned out to be the two matrix pipes touching and with vibration this lead to the noise, fixed by replacing the damaged pipes and no noise since.
If you pull the lower right panel off the centre console, down by passengers right foot, look behind the dash you will see the two silver pipes, maybe cut up a sacrificial car washing sponge and place between the two pipes, they have a tiny gap between them but easily enough to push a couple of slivers of foam.
Then it the sound persists this isn't the cause.
However if it does cure it, no need to take the car in for further investigations.
I'm hoping that you get it fixed soon.

Daft question, why would the engine warning light come on for a failed glowplug? I could understand the glowplug light coming on not engine management light. Maybe there is something more to this.

Behind the dash there is a large air controller venting box (heating and cooling). That contains about 5 actuators (motors) that adjust the air thru various vents across the dash area of the cabin...air condition venting. On the J11b these vent controllers are very clicky at times.
