all gti,s have a secret digital revcounter

[franmav4]

Ive tried it on my 89 Gti 16v and it works after a while of trying.

There are two types of dash's if it makes a diffrence.

VDO and Motometer.  I have the Motometer. But ill try on my Gti with the VDO.

can't get it working on my '87 8v. Does the same with position 1 or 2. Displays: 8, 2000, 1925, 3, 955. Whatever the revs those numbers stay the same.

I read a while ago about another little trick similar to this. Displays the inlet manifold pressure. Never got that working either.

If you actually go to a VW garage and spk to the workshops dept you can get a whole list of things you can do on the MFA. I think it was the early diagnostic aid before computers.

Whoo-hoo - it works, but what do the other readings mean - I understand the rev counter (all beit with a delay), oil, and temp but what are the rest??

Have a look at this site, explains most of them.
