WHOOOOOOOOOOP sound

[falco]

Yes it is quite loud. I had a car full of people the other day and it made "the noise" and when it happened they all looked at each other and said "whats that" .

[nugget666]

So is this harmful in anyway or just makes a sound? its kinda off putting

I have the problem too.. and i want to take it to the dealer..

Just want to know what should I say to the dealer?

Should I just say fix my TX Valve, there is a fault, because it keeps making a whoooop sound when having A/C on.

Will they understand it and fix it?

Or should I say something else? like say i found this problem on a forum and it's a fault in TX valve..?

Can anyone please let me know..?

Thanks!!!

Yes take it to the dealer, and tell them the tx valve is making a whooping sound.
From my personal experience the dealer will say "leave it with us and if we can hear the noise we will diagnose it." Of course it NEVER makes the noise at the dealers and they will do EVERYTHING in their power NOT to fix it under warrantee.
So its up to you to be VERY forcefull and tell them not to return the car to you unless its fixed.
If you dont do that the chances of getting it fixed under warrantee are about ...zero.

My 04 Euro makes the whoop sound regularly, I've told Honda about it ( car still under warranty) and they say it's 'normal'... I just live with it !!!

cheers

Mine did that too till I told them next time I dropped it off for a service I was looking at buying a Jazz (which I was) they fixed it. I got my Jazz too but not from them

Has anyone experience the Whoop sound from the CU2 euro? I started the car the other day and immediately after it turned over, i could hear the car making the whoop sound. Could it really be the TX expansion valve? The car is only 6 months old.

LOL i found this video on youtube

same as what happened to me today.

Same sound on my CU2 when starting the engine. Happen only in the morning when car stayed overnight or if parked for long time. But same sound....

i only just skimmed through the thread, but you will need to send it to get fixed, something about a valve/AC.

Had this WHOOPing problem a long time ago with my CL9 Black Luxury Euro in 2003. There were very very few replies back then but aaronng's diagnosis is spot on - the TX valve is what's making the noise and it needs to be replaced.

Back then I had warranty to cover this but I sold the car before it ever got replaced - entire dash needs to be removed and it is an extensive job.

The WHOOPing noise got progressively bad over time that it could happen anytime - be it during winter/summer and the A/C is on.

Thankfully nothing on my current CU2 (touch wood ...)

I concur with primetimex, sounds like the Tx valve which is expensive and should be fixed under warranty.Honda will claim it's a normal operating noise which is rubbish and not befitting of a car which is supposed to be best in class. I have owned old mazda 626's and a Mitsubishi Mirage which had a/c systems that were reliable and QUIET.....go figure.

I eliminated my noise by selling the car and getting a Lexus !

Good luck everyone !!
