It did when it left the factory. Near side in space between bumper and front wheel.

Cheers mate is it the same to remove as the 182

Should be, wheel off, arch liner off, undo horn bracket and unplug the valve, you will need to bung the vacum pipe up takes half an hour ish

I have just had a go at removing the valve i removed the little black valve and blocked up the pipe is this all i needed to do not really notest any differance

Ive took mine off seams louder but im without fogs at the moment so that could be why.

If anything saves a little weight but to be honest unless your down there i wouldnt make any special effort to take it off.

May as well get rid, you don't need it and its not there to improve throttle response/power etc so no harm in throremoving it. It's not going to make any difference to you drive experience though.

What does the acoustic valve do? And can someone post a picture of it please

 

[john lloyd]

Was something to do with keeping induction noise down, iirc for one if the foreign markets.
