Title: Missing some readouts on MFA
Post by: JezGTI on 12 November 2003, 21:06

Distance driven, MPG and MPH appear as --- on my MFA.  The other readings seem fine.  Any ideas?

try disconnecting the battery for a few mins. mine use to get stuck when I had a sh1te battery on there and doing that would reset it

My MPH just stays on a random figure. Is this normal?

check the vaccum tube attached to the back of the clocks, if it aint attached then it cant read the MPG or the avg MPH

What's the best way to get to that?

unless u have really small hands and arms that bend in several places the lot has to come out ;D

pull out your stereo, pull off all the switches and blanking plates, pull off the heater controls. There's 3 screws on the top (1 under the cage for your stereo and 2 above the dials) and 5 (I think) on the bottom. Once they're all out you can remove that cover. Then there's a screw either side of the dials to release them. reach round the back and unplug the speedo cable (this is a b!tch) then they should move around enough for you to reconnect the vacume hose

do you not have to take off the steering wheel as well?

The oil temp is usually a disconnected wire. Look at the back of the engine compartment for a green wire with a black strip (as I recall) and slip it on to the connector (at least that solved my probs :))

Back of the engine compartment? Where are we looking mate?

just above my oil filter there is the green and black wire connected so im not sure where you mean?

OK, had the dash out and it seems like the vacuum hose was properly connected (although it wasn't that easy to see).  So I still have mpg, miles and mph as ---.  Any other ideas??

check the pipe then for leaks

Thanks Gambit, do you know what route the vacuum tube takes in the engine bay?  I thought this tube was only used to calculate the MPG, does it control the 'Miles'  and 'Trip time' function on the MFA too?

I have tried to check again to see if there is a leak on the vacuum pipe where it is connected to the MFA.  The problem is can feel the tube with my fingers but don't know how to remove it from the MFA.  Don't want to pull it too hard in case of damaging something.  Anyone know how to disconnect this tube from the back of the MFA?
Any help with the previous message would be appreciated too.

the tube just slips over a nipple on the back of mfa i think, but it may be a bit tight cos obviously it needs to stay on once its on

mine reads the same and all hoses good. i think it is the gizmo on the gearbox that tells it engine speed.
