Bau hangus

[wwshyue]

Hi guys,

All this while when i travel long distance and stop, i can smell a little bau hangus when i get out of my coupe....i never take it seriously.

Last weekend when i travel back to my hometown i decided to give my coupe a push and see how fast it can go......so i start accelerating from 110 and continue going. when i reach nearly 190kmph and still going suddenly i can smell a very obvious bau hangus even with my window closed. i straight away slow down and the bau hangus slowly go away and at last dissapear. i din notice anything wrong with my coupe after that. when i reach home, as usual i can smell a little bau hangus after travelling long distance.

Just wanna know is this normal?? or is it anything wrong with my break system or clutch system?? or any other possibility??

This is NOT normal.
Kelvin, I'm not sure about clutch, but I don't think it's your brake.

Some rubber is burning, that's for sure. Do your tires touch your fender when you travel in high speed? Coz yours is lowered.

PS: Speed trap everywhere still travel 190 ar?

maybe you have an exhaust leak in the engine and the smell is coming in from the air-con vent? as you know, the RD1 aircon flap thingy tends to get loose overtime and letting the outside air in..

i dunno..just a guess..

Kelvin, it could be the brakes. Tried sniffing the whole car the next time you smell it to identify the location of the smell. Did you release your hand brake "maximum" ??

Btw, I remember there was a thread on AirCon smell. Occasionally, I get "urine like" smell and some other time "petrol" smell coming from the air con. Any clues to this??

Can you identify whether it is burned wire/plastic smell or just some oil or metal burned smell?. It could help us to help you narrow down a bit. It could be either the break pad or the relay wire which tends to get very hot when it is live.

darren, looks like some animal like rat went in and pee inside your aircon intake.

Kelvin, indoor or outdoor get stronger smell?

haha... animal pee? no lah, I don think so:X-:
petrol smell? must be petrol loh, but I don know why....hehe.... I do have this petrol smell last time but not from the air-con, every time I steep out my car after driving, not all the time, just some time. Every time drive to workshop for checking, that time no smell, so can't check. But now no more already, my car sot sot de.... can cure it self:Not_Impressed: (even did'n give panadol....)
The urine smell, I do have this too, this is b'coz my car carpet is wet at the passenger side, I always tapau teh peng & hang to my gear knob at passenger side, the ais water get to the carpet & growing fungus at the back of the carpet, when air-con is on, the blower suck the air from the passenger side together with the smell of the fungus to air-con, this is how my urine smell come from. After wash the carpet no more smell. It can be if ur cooling coil is very dirty, fungus growing too, have u service ur air-con before?
The burning smell, can be ur break, check ur break is it jam, can not be cluch smell b'coz u rich 190km, maybe is oil leaking to exhaust too or some thing is burning:mouth_closed:

 

[BlackSamurai]

darren, the urine smell, after reading Yu's post, now i remember, I have that in my old Proton Wira, and that's because my carpet always wet. Do you have such problem?

 

[dartango]

no leh. I don't allow or bring food or drinks into my car. The "damped" or urine like smell comes occasionally only. However, the petrol smell is new. Again it comes occasionally only. Air con sot sot oredi. :angry_smile:

 

[Ace]

You have to check the drainage pipe for the air con as well. It sometimes leak to our internal carpet. I had mine fix and now no problem. As for the burn smell. It could be engine oil contact with your header or extractor like Yu911 mentioned.

 

[BlackSamurai]

maybe you have an exhaust leak in the engine and the smell is coming in from the air-con vent?

my myvi have such problem, need to send for waranty claim. :sad_smile:

worst still, plastic carpet melt. Everytime i rev, plastic smell come out.
Now no more, i guess plastic carpet fully melt i suspect, no more rubber to burn.

 

[Ace]

BS,
You better send your myvi for checkup. burning is something not to taken lightly

 

[BlackSamurai]

yah. will do so.

 

[Daniel Lee]

I suspect that Kelvin's tires are rubbing the wheel wells.

Bout the aircond case, sometimes the vent will blow out sponge.

wwshyue,
Dude.. have u checked ur radiator? try checking the engine cooling system see if everything's working fine. From ur description looks like its related to these things. Try have a look ( and sniff:) ) Good luck.

 

[Yu911]

Last time my windscreen leaking water too, just come tiba tiba, before no leaking, & din't change windscreen before, but fix liau, take out the windscreen & sealant it agant.
Have u change or service ur air-con? At noon or hot sun dose ur air-con cool? If not it can be ur cooling coil leaking gas, the gas + a bit of the fungus at cooling coil will get strong smell too, check ur gas pressure.

 

[BlackSamurai]

kelvin,

just curious, does the smell exist before you change your timing belt?

 

[Ace]

Daniel,
Air con venting sponge means service is needed to change the sponge as well.

To all,
If you guys car have heating function like mine then you have to beware as it uses the radiator water heat to route inside the car to heat up the air. When it started to leak it will smell funny and a little burn smell as well. When it totally leak the air con will be venting all the all hot steam from the radiator. The water in the radiator will dry up pretty fast. You can check the water level at your radiator for any sign.

 

[Daniel Lee]

Ace, I haven't change the sponge yet but the sponge had stopped flying out from the vent for some time. I think there ain't any sponge left in it.
Any idea how much the sponge costs?

 

[Yu911]

me too, sponge stop flying, hahaha.... but i change my self, curi some sponge from my fren shop but too much, the air-con hose can't goes in, hehehe, curi too much, get some out than ok, my fren saw I put so much than said ppl curi also a bit only but I dare to curi so much, this is what happen the hose can't goes in 'dai sai':cry_smile:
