reeces555 Posted March 18, 2015 Share Posted March 18, 2015 Having picked up my first zed today I have noticed that mainly when accelerating from about 2k rpm upwards in 3rd and 4th there is a noise like a sharp intake of air coming from the front passenger side lastjng for about 2 seconds then stops? Anyone ever come across this? Sorry if there is not enough detail here just hard to explain...ive got 3 months warrenty just want to make sure its nothing I need to return to the garage with.

a2orry Posted March 18, 2015 Share Posted March 18, 2015 Standard air box should be quiet possibly a small air leak. Check the pipe thats fitted to the air flow meter . Quote Link to comment Share on other sites More sharing options...
reeces555 Posted March 18, 2015 Author Share Posted March 18, 2015 Will check in daylight tomorrow thanks mate...just seems strange it does it around when the shift light comes on on dash Quote Link to comment Share on other sites More sharing options...
a2orry Posted March 18, 2015 Share Posted March 18, 2015 Sounds like your heavy footed on throttle and brake pedals you can set the change light with the buttons on the right of the dash binnacle . My advice is learn more about the car and how it drives before you go mental Quote Link to comment Share on other sites More sharing options...

My advice is learn more about the car and how it drives before you go mental the light was set to come on at 3000rpm I havent been driving the car hard by any mark. I wanted to try thr brakes etc while I have the warrenty didn't want things to drag on after the warrenty finishes Quote Link to comment Share on other sites More sharing options...

a2orry Posted March 18, 2015 Share Posted March 18, 2015 If your worried about work needed after warranty go to your local garage get the car on a ramp pay for the half an hour or so that it will take to check suspension brakes make sure engine gearbox diff are all dry . Also some of these cars burn quite a lot of oil you should of already had the dip stick out best to do it when the car's sat over night. 1 Quote Link to comment Share on other sites More sharing options...
Tay Posted March 19, 2015 Share Posted March 19, 2015 Is it a small whirring / vibration noise around the 2k rev mark that you can reproduce even if you accelerate gently? Quote Link to comment Share on other sites More sharing options...
reeces555 Posted March 19, 2015 Author Share Posted March 19, 2015 Is it a small whirring / vibration noise around the 2k rev mark that you can reproduce even if you accelerate gently? it happens when I apply more than half throttle but only last a second or two...its more of a sucking or blowing noise, hard to describe.

bamdc2 Posted March 19, 2015 Share Posted March 19, 2015 Mine does that but I do have a pop charger induction which is normal (awesome) sound. If it is a standard airbox then maybe you do have a slight air leak. Try opening up the bonnet with windows down and rev the car slightly and see if you can identify where it is coming from. Obviously when it's on your drive or something and not while driving!!! lol 1 Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted March 19, 2015 Share Posted March 19, 2015 (edited) You can get some carb cleaner from Halfords, spray it near the vacuum lines to see if it's a leak (engine idle will drop/change noticeably). Example: Also, might be worth posting up a photo of your engine bay to see if anyone can spot something.

Might be worth meeting up with a member near you. Doesn't sound like any noise i've ever heard. Very rarely I've heard a noise thats like a vibration at 2k revs and lasts less than a second but its randomly come and gone away again so I just ignore it if i ever hear it nowadays. Our cars are pretty solid I'm pleased to say. 1 Quote Link to comment Share on other sites More sharing options...

Fyi: HFC's are not De-Cats. It stands for High Flow Cats. Basically similar to standard Cats but just higher flowing AKA sports Cats. 1 Quote Link to comment Share on other sites More sharing options...
