Hello all,
I finally got my MFA working a couple of weeks ago, and would like to understand exactly what it is telling me!
on the washer stalk, there is a switch with 2 positions on it. labelled 1 & 2. by pushing the switch further right, it reset's the MFA reading for position 2. Position 1 is stored though, and I can't seem to reset it?
Is the reading supposed to be an average for the whole journey?
I've noticed that in the morning, the readings start from 0 (distance, and average mph), but if i switch the car off for a bit, and start it again, the readings are stored from the last journey? how long do I have to leave the car switched off for, for it to reset completely?
Could someone explain this to me? I know it isn't going to be very accurate, but I'd still like to know what its doing.
Cheers!
Chris.

To reset position 1 push the switch right over to the left as you do to the right for resetting 2.
Setting 1 stores the information and just keeps clocking it up until you reset it.
Setting 2 is the setting which only stores information for individual journeys, I think the memory of setting 2 is cleared about two hours after the ignition is switched off.
The most handy thing about the MFA is being able to keep any eye on your oil temp, my MFA lives on that setting.
-
1 is for the current journey within 30mins or so i think. to reset it push it left and hold
2 is for all journies until you reset

Whoops did I get my 1's & 2's mixed up :embarassed:
I was trying to visualise it from memory.
-
I was pretty sure that it was position 1 that I couldn't reset. I will try it again later on!
What oil temp is normal? I haven't got a clue what mine runs at! The water temp guage is pretty high.
-
Oil temp depends on whether it's an 8 or 16v as 16v's tend to run a little bit hotter.
Typically it should be somewhere in the range of 90-110
My 16v runs at about 100 when driving normally and about 108 if I'm driving enthusiastically on the motorway.
-
Cheers for the replies.
its an 86 8v.
I recently changed the coolant, flushed, and reverse flushed the coolant system, and fitted a new thermostat.
I will also be fitting a new fan switch soon, as mine only switches the fan on at the higher speed, so the engine gets quite warm before the fan comes on.
I understand the fan should be switched onto its low speed when the water temp gets about half way ish? mine currently gets to about 3/4 high, then the fan cuts in.
I will check my oil temp on the way home. Hopefully everything will be ok.

My 8v runs at about 80 - 90 when driven sensibly and then up into the high 90's when I'm giving it some beans.

Mine is also a 8v and runs dead on 92 when warmed up and normal running.
Had it up to 100 on the way to the meet yesterday but that's the hottest I've had it. :smiley:
My old 8v got up to 110 and ran fine. Others I've heard on valvers have had them in the mid 130s :tongue:
-
mine never went higher than 92 yesterday :S but its still pretty cool out there in the summer i seen it hit 112 when i been thrashing it.
also to reset the 1 & 2 position on the mfa it wont reset in all modes for sure it resets on journey time but on average mph mine doesnt reset it gets a little confused says 0 then says the average speed again could be just my mfa :S bit like my golf past its prime lol
-
54c when doing 60mph at 6am in the morning but between 60 and 90c :smiley:
-
my oil one says nothing
i just keep it on MPG 31.4 at the mo on my 8v
-
My MFA doesn't give me an oil temp reading - the cooler housing for some strange reason came from a carb engine and only has an oil pressure sender and no hole for the temp sender. I have a new housing and cooler to put on when I get the oil changed though!
Just out of interest - at what temperature does it become bad news!?
-
Something I just found out recently.
If you hold down the button on the end (change selection) the MFA display goes back to time.
Very useful if your on Miles and what to see how long you've been travelling, saves scrolling through the whole set of settings.
