C&C: Foul smell during acceleration is normal

[manmerlion]

Hi bro, after you send to cnc eunos workshop and tested with his fast and furious skill...what is the finding and did they slove the problem..many thanks

The SA told me it was the first time he encountered this problem. I was dumbfounded. Later in the day, he called me after consulting his workshop manager. According to this manager, the foul smell is normal. Again I was dumbfounded. This is why I went to C&C showroom to test-drive their C180K. To my surprise, the same problem ensued after some hard acceleration. I was dumbfounded once again. Now, I just feel dumb buying this car. Ha...ha...

Thought I was the only few withi this foul burnt smell issue. Is there really no way to get rid of it? I realised that it is getting worse as the car ages. At 110km/h the smell is so bad it chokes the driver and the passengers.

Get a stronger air freshener?

Yes Yes!!! The smell gets stronger as the speed goes higher..ya when it hits 110km/h and above..

It used to be at 130km and above. Now it gets so bad my wife complains and asks to open the windows for ventilation. Apparently the rear seat passengers get it the most.

Haiz.. what can be done eh?

I think u never press the recirculation button on the aircon which always reset once u cut off your engine.

This smell seems to be characteristic of forced induction vehicles. I used to drive a turbo car and smell exactly the same on hard acceleration.

Perhaps it its the car design did not take into consideration of this issue when they intended to let "fresh" air in.

The bad smell is pretty bad. Worst than my fart. There's less smell when i turn on the recirculation mode.

I read somewhere that sulphuric smell is an indication the catalytic converter is working fine. As the converter ages, the smell becomes less pronounced. I hope that's the case for my ride, which is 9 month-old.

I had this sulphuric smell before (when I change my original CAT to high flow cat)

my wife said is like urine smell.

but after I change back to original cat the smell is gone.

just for your info.

if u really thinks that your CAT is not working, and cannot claim warranty.

It cost $1500-1600 for a new CAT, it consist of one pipe with 2 CAT on it.

my car is a earlier version W204 M271.

So has any one get this issue resolved?

By the way, went off to C&C Pandan loop yesterday morning and complain about the foul smell at 110km/hr. Test drove and upgraded air-con software, so far, no more smell at 110 or 120km/hr.

Hope this helps.

Air con software, so chim arh

What car are you driving? It is true that it's normal to get the smell for A and B class when accelerated hard.

Confirmed is normal for B class. Stupid design to take in hot air from the engine compartment. I heard some owner seal up the air inlet vent and have it permanent on internal circulation. I like the idea too.

By the way, I am driving a C180K FL.........tested yesterday again, no more smell even past 120km/hr.....so far so good. There is probably a separate software module for the air-con and the foul smell is there only at 110km/hr and above.

I think is 2 different problem.. Aircon and exhaust burning smell pls don't mixed ??
