Car Got Really Loud When Driving In The Rain

[PranK]

Hi all

Last week in that crazy Sydney rain, I was driving my little Bora when suddenly it got really loud. It sounded like I had damaged the exhaust or manifold or something. It was hard to test power where i was but it seemed to still have the same power and wasn't missing or anything that I could tell.

Thing is, after a few hundred metres and 5 mins at some lights it went back to normal.

Any ideas?

Thanks

My Stageas exhaust got deeper and lost power at wot when the afm was playing up.

Not sure what sensors a bora has, but could be a possibility if some dirty water made its way into your afm. If it's a map, I have heard of similar experiences when there is an intake manifold leak.

Water on sensor sounds plausible

Thanks guys.

What would the noise be though? If there is water on the sensor, what's the noise?

Is it still doing it?

If no then I doubt you will find it

Perhaps due to the perception of danger of wet roads your senses were heightened.

Science.

Hasn't done it since.

Why worry? All is sweet

I'd say it's just a case of the car being like a child nagging for an ice cream. "Dad, I really want a bigger exhaust. Dad, I REALLY want a bigger exhaust. DAD! GIVE ME A BIGGER EXHAUST!!"

I recommend fitting a bigger exhaust.

Are you sure a truck wasn't driving past you?

But it has the most adorable German accent when it nags!

[Hadouken]

It says papa. Aha

You know when I read this I thought you were dead set mental.

Then it happened to me!

Was raining, was approaching a hill.

Car got noticeably louder. Was weird. Lasted 10 seconds or so.

All I can put it down to is something happening to your ears, due to the pressure changing due to the weather.

Something scientific like that.

[PranK]

Something scientific like that.

Or ... that I'm (we're?) mental.

Haha.

Well certainly can't rule that out!

[Hadouken]

Now it's a phenomenon.

The aliens did it!

You guys running external wasteubrogates?

Only in my roof scoop.

Temporary exhaust leak. Check all bolts and gaskets
