@Carl123 you can definitely hear the difference with yours. I will try and take another audio clip without my fan running.
Carl did you change the adjuster to or just the the chain and tensioner
@Carl123 took another audio clip http://daz.co/audio/carnew1.mp3 still think mine taps a bit more than yours.and heres the before http://daz.co/audio/open.mp3
Recently had my thermostat changed and now that the gti is running at correct temperature the engine rattles when warm only when idling.....didnt do this before the thermostat change so not sure if it is the chain! Seems to be costing me alot of money so far :( can you guys advise me from listening to the video? Very loud in the cabin as shown on the video. Any help would be grateful before I go get an opinion at VW. Thanks
