Hi guys, ive had this problem for ages now and i have recently purchased vag-com i eonderd can somebody tell me how i can tell if my timing is out using vag com? something to do with the cam timing? I have had a shudder, idle vibration since i bought the car a year ago and ive done 9000 miles in it since. Also how do i up my idle speed with vag-com? Do you think the vibration could be the result of timing? Also it had a timing belt kit fitted 15000 miles ago, however thats all it had, a water pump was never fitted at that time! For me its common sence to replace the water pump aswell. Do you think this is an issue? Should i replace the whole kit again, i.e. water pump timing belt kit etc. Also is this a job i could do myself? How much would this cost? Would be great if someone knows what my problem could be with the rough idle and vibration.
