Hello, I'm a newbie to owning a golf mk4 and I just bought a timing belt kit. The timing belt has the M and when I looked at 7zap web I can seen there is a D and M version for an AGR engine. My golf is a 1999 2 door 1.9 TDI AGR engine and an import from Germany with vin#wvwzzz1jzxw268210. The kit was bought from a VW dealership and I am confident I got the right kit as I gave them the VIN#. It's just the curiosity in me what's the D (AGR 565 000 note in 7zap) and M (AGR 565 001 note in 7zap). I hope you can shed some light on this. Thanks.
