Have a Golf IV 1.6 Bj.1999 and annoyed every time the service starts Piepserei, so I should go to the workshop to be abgeneppt for incoming customer service. My oil change I can make yourself and at a reasonable price per liter and not fantasy prices the workshop. That's why I looked around on the internet and am also has shared. Was a bit skeptical because of various reviews whether the part really works. Have been well received by a number of fellow sufferers reporting that is described in the instructions for the golf (on page 12), as the service interval display is turn off. Does not work for me! I just got in spite of title but then decided this Si-reset tool on Amazon to buy. After faster delivery (as always with Amazon), I then connected the adapter to the service connector and lo and behold, the thing has as lt. Manual described, works perfectly and I was able to stop the annoying beeping. Am completely satisfied and would buy it again.
