Hi guys
my golf cabrio mk1 since I bought it the mfa instrumentation does not mark, or rather displays the dashes clock and oil temperature work perfectly, do you know if the size of the tube has a specific length?

I have a feeling and it's only a feeling but I suspect most of the problems with the MFA is down to the switches on the stick. You used to be able to buy them fairly cheap from German and Swedish back in the day but not sure where to get one now. Second hand is likely to have the same problems.

So I guess you have clock time, time traveled, oil temp and out side temp all working as it should?

for MFA switch testing first follow the wiring form it, one pin is earthed with the dash clock to the side of the head, brown/white wire. if this has gone bad in the past and the PO just cut and ran the cluster earth to the chassis, then the stalk earth would be missing.
if you jump each pin of the stalk to earth it will trigger the corresponding mfa functions, the first question is what stalk/clock setup do you have? early with just the mfa mode button on stalk and 1/2 switch on clocks, or late with both the mode and 1/2 button on the stalk

Remove the cardboard above the pedals and you can get in behind the instrument to unplug stuff but it's not easy with the front seat in the way, makes this job easier if you remove the front seat.
If you have small hands it is possible to unplug the main plug into the instruments by pull them out a little.

white/red - change mfa mode - main clock plug pin 8
black/white - change between memory 1 and 2 - 2 pin plug on the back of the clocks
red/white - hold to clear mfa memory - 2 pin plug on the back of the clocks
if no response run an earthed wire from chassis/earth claw/wherever and repeat the tests

1st check is to remove the clocks and check the blue foil for any obvious damage. if you flip the clocks forward with the wiring still plugged in you can check for ignition live across the live and earth pins on the speed sensor foil, its the 2 outer connections.
if you find the connections are all good you can test a new speedometer by putting something suitable into the back and spinning it manually, though you'll have to spin it over a thousand times to get it to register 1 mile on the distance setting
![:lol:](https://vwgolfmk1.org.uk/themes/default/images/ocf_emoticons/lol.gif)
later type clocks have a secret MFA mode, if that works on yours put it on the speed sensor setting it should register 4 pulses for every rotation of the sensor
