Gurgling Noise

Zoot1948 · October 17, 2017

Has anyone heard a "gurgling" type noise from under the dash area of the NX? My wife thinks it is from the radio but I'm not so sure.

It doesn't happen all the time and sod's law, when I try to record it the flipping thing doesn't do it.

Any help would be appreciated.

Not something I've come across so far @Zoot1948but as I always have music on I'm not sure I would have heard anything. Will be interesting to see what others think and if this is a common feature.

Could it be something to do with the air con?

That could be a possibility @First_Lexus. I'm seeing about re-siting the dashcam soon so I'll suggest they look at that- thanks.

Few things it could be:

Air con gurgle if been regassed and not done properly.

Or its the normal hybrid gurgle which happens every so often.

Many thanks @rayaans. As far as I know the car has not been regassed as I've owned it since it was 6 months old. Regarding the "hybrid gurgle" I wasn't aware there was such a thing. My previous car was a Honda C-RV EX diesel and I have no experience of hybrids.The dealer didn't have time to look at it when I was there to have the dashcam re-sited as that was on a "drop in when passing" scenario.

I'll mention it to them when I visit next.

Unlikely to be air con gurgle then.

The hybrid system does make some gurgling and whirring noises, especially after its turned off (it freaks people out in the car park) as does the auto parking brake so most likely it is normal behaviour of the hybrid system.

The first time I heard it on my GS made me think something serious was wrong. Now I find it quite endearing!

Funny enough today I switched from DAB to FM as the drop down info informing which DAB station you are listening to drives me crackers with its frequency. Surprise surprise whilst on FM there were no gurgling sounds at all and no infuriating FM drop down info!

I'll be doing a reasonably long journey next week so I'll see if this is the cure.

Probably listening to Gurgle FM....

Zoot1948 · November 2, 2017

Ok, so I've covered just over 280 miles in 2 longish journeys with the radio on FM (gurgle fm isn't too good though!) and the result is - NO gurgling noise at all and the drop down bar at the top of the screen showing which radio station you are listening to is much much less in frequency.

Me thinks it has something to do with the media system. Anyone else had this symptom?

Not sure about hybrids as so many things are different in them, but gurgling behind the dash in a 'normal' car would most likely be coolant and/or air in the heater matrix. Check coolant level and top up if necessary
