Starter motor Bosch or OEM Volkswagen
MkIV 2.0 auto trans starter. Bolts right up to an 020. Spins the engine faster than the original did. And, it's smaller and lighter, too. I put one in my Scirocco a few years ago, when I replaced the trans & clutch.
So, after a fun summer and fall of some great worry free driving something came up.... it wouldn't start properly. So naturally I took the battery to advanced auto parts to test it, it worked fine and passed, then tested the starter, and was reading a bit slow, can't quite remember the cranking speed but it was in the low 100's RPM. So after days of having to pop start the car, yes I know.... poor clutch! I got a brand new REMAN Bosch starter, and installed it. For the next two days it started just fine
Can confirm Mk3 starters work on Mk1s as long as it's a manual Mk1, have had one on for years, have seen it done on several Mk1s.
So I picked up the MK4 unit. It sounds different than the old unit. From what I read it's got gear reduction in it. Car starts fine. Glad to have some new tech in this old car, and it's funny, the MK1 unit has a 1 year warranty while the MK4 unit is lifetime. Put another check in the pro column for the MK4 unit!
The starter is a Bosch premium re-manufactured unit and tested good before I put it in.
After testing, 14.8 v at the starter when cranking is better than the .7 volt drop before! and now there's no battery drain!
How much more effective is the gear reduction starter compared to using a MK3 starter? I'm running a mk3 8v starter in my '80 scirocco and absolutely love it. Much more effective.
Yes - works great, spins the engine so easy. And no stupid bearing to mess with to boot.
We got the battery tested - it's fine. Tried tapping the starter, but still no joy.
Go for the reman Bosch. They should call it Neverlast or Durajunk
