Slight misfire on tick over.

(1/3) > >>

hi all.

once there the car is warm, it seems to have a slight misfire. you can feel it more, say when sat at traffic lights with ya foot on the brake,  ive had the plugs out, they look fine , gave them a clean. 

scanned it with vag-com, which didn't bring any faults up.

also i have noticed it seems to be making a hissing noise on hard acceleration, louder than it normally does. its like a hose maybe leaking. 

could this be the diverter valve, causing these these two problems?

can i use vag com to check the diverter valve?

car is jan 07 ed30.  dont think it will have the latest version of the diverter valve in it.

It does sound like it could be the fault. Take it off and give it a look over. They are very easy to get to with a KO 4.  :happy2:

cuzmk5:
 Are they at the front of the bay on the ko4? unlike the ko3 where they are behind the inner wheel arch.

gona ring vw 2morro, warranty job i think. 

Top Cat:
Yep easy access i believe.  :happy2: you have to go under the car for the KO3.  :sad1:
