ive got a similar problem to a previous post but i dont think its fuse related. just wanted to know if anyone has had the same problem or might know a solution.
everything on my MFA works except the oil temp reads 160 continuously and the outside temp just shows the time. i thought maybe the outside temp could be a fuse as it doesnt work at all but i havent tried pulling any fuses yet.
i guess the oil temp could be a U/S sensor but i dont know the location of this or how to troubleshoot?
HELP! :cry:
-
1. replace the oil temp sensor, sounds liek it has shorted to ground. Check the wiring first, it may have rubbed through somewhere! Easy check is to simply disconnect the sensor, if the guage reads --- then its a sensor fault. Its the small one on the oil filter housing with a black/green wire.
2. Might be the outside sensor is fault or has fallen off, it should be clipped to the inside of the wing just behind the front bumper :)
-
nice one jonny! ill have a gander this afternoon :smiley:
-
cheers jonny, turns out the oil sensor is at fault as i get the --- when its dissconnected. so ill put up another post to try and get one of those 2nd hand unless you know if i can get one from GSF?
as for the outside temp. could you be abit more specific as im having truble locating the bugger. which side is it supposed to be on???
cheers
-
You can get em from gsf but they give the wrong reading. ie, they read 60-70 when you should get 90-100. I had two and they were both the same. Buy yourself a VAG one, about £12 I think.
Cant help with the OTG, sorry.
-
outside temp is behind the passenger wing, clipped into a hole thru it just level with the bumper. Or at least it should be ;)
-
I also have a drama with the MFA oil temp reading but it shows ---- with the sensor connected. On the service record when I bought the car a garage said it was a 'printed circuit fault'. Any ideas as to where I start looking ie Instruments or sensor?
-
OK, first take off the spade conector to the oil temp sender and earth it on the block etc. If your mfa oil temp now reads 160 instead of --- then its the sender that has died and replace with a vag one. If not then check the circuit stating with the green and black wire :smiley:
-
also worth noting that below 50 degrees the oil temp will display ---, so make sure its warmed up then check again ;)
-
:angry:GRRRRRRRRRR
i bought a new temp switch (eventually! as its actually called pressure switch and i got given the wrong bit by the nice man at VW)
fitted it easily enough and got some differant readings other than 160 degrees. but it mainly stays at 160 except when at idle just after starting i get --- as the oil is below 50 i guess. and when dipping the clutch at traffic lights i get all kinds of random readings.
changing the switch has done something but nothing that has helped the matter. what now?? do you think the wiring could be shorting out somewhere along its length? any other suggestions???
cheers
-
definitly sounds like the wire is shorting out somewhere to me

Sure you got the right bit? you need:
049 919 563 A "oil temperature gauge sender" £12.19
white colar 0-180C

that isnt the correct part. thats the bit i got given first time around. its completely differant to the forward most switch on top of the oil filter housing with the green and black wire as discribed by rubjohny i think.
it has the same thread but its alot smaller, it doesnt have that big white insulation around it also theres no spade connecter.
i went back in with the bit discribed after taking it off the car and the guy instantly said thats the oil pressure switch and went to fetch one for me.
but still no joy! :sick:
-
^ I think your swapping the wrong bit then! I am certain I have given the right part #. Its defo the green and black wire though. Would you like a pic?
I wonder if your wires are crossed. :shocked:
RubJ - please confirm the part number :smiley:
-
Right the rain has stopped so here you go. The red arrow is your oil temp sender on a 91H 8v GTI :smiley:

Hope this helps :smiley:
-
hmmm how queer! thats what i changed. mine is differant to that one though! the part number you are quoting is the one they gave me at VW 1st time around.
the one i have fitted is exactly the same as the original one. my golf is a 91J 8v gti.
as the oil temp has never worked since ive had the car maybe a previous owner fitted the wrong bit???
however that part number you have quoted has a differant top end and so the spade connected wouldnt fit onto it???
ill get some pics if i can. maybe ill go back to vw and get another one touch the wires and see what happens??
annoyingly now i havent got the part number of the switch i have fitted as i returned the original part and just swopped it without bothering with a receipt! GRRRR i wont do that again! :angry:
-
That is the oil temp sender you are replacing, Simon that part # is for a VDO oil temp guage, the correct sender for the MFA is this one:
049 919 501 - temp sender, 1 pin black, 0-125degrees - 22.80+VAT
-
I was gonna say why bother fixing the MFA, until i realised that it's the oil temp thats fooked, as this is the only mfa function i use!
:smiley:
-
hmm, the plot thickens :laugh:
I have just looked at my VAG invoice from when mine failed and it says 049919563A Gauge £12.19. This is fitted and in the pic you can see it has a white colar. It works perfect (90's arround town and 100 ish at 70mph) and I have verified the temp reading with a contact thermometer :nerd:
btw, John, your posts in the past have been of great help to me when I was a lurker. Thanks :smiley:
-
Problem with a contact thermomiter is its telling you how hot the engine block is, not the oil ;)
It may still read correctly I guess, just up to 180 rather than 125. Even if it reads incorrectly it should still show something on the oil temp setting!
-
Hi jammac, Let us now how you get on and how you ressolve it. This old chestnut comes up alot :smiley:
-
yeah cheers, ill let you know. im trying to study for an exam at the mo so leaving the pesky car alone! its taking up valuable revision time! :sad:
-
My 16v has --- on the MFA so i'm waiting for some solutions to the problem, i've replaced the oil temp sender to no avail.
-
ok heres the pics! (only just worked out how to add pics)
this is the new oil temp sensor fitted

the old one
(http://i193.photobucket.com/albums/z34/jamiemacpherson1981/DSC00019.jpg)
ive come to the conclusion that the original part was the worng part? as it looks nowt like the one pictured previously in this post.
ive got the part number and have ordered it from VAG! hopefully this will cure my 160degree continuous oil temperature! :sick:
-
Thats an oil pressure switch not a temp sender! :smiley:
Go get the part either RubJ or I mentioned, it will be much smaller (see pic) and you may have to use a different spade connector. I would try 049 919 563 A "oil temperature gauge sender" £12.19
first, its cheeper than the one RubJ suggests and works for me :wink:
Make sure it uses the green and black wire. :smiley:
-
WOOO HOOOO! GREAT SUCESS!
went down the scrappy today and robbed a new sensor fitted it and my oil temp was reading 50-60! i thought oh no here we go! theres more to this than what i thought.
later that same day i went to pick up my new one from VW and it works perfectly! im getting 92-98 which is prob about right from what ive read on here.
thanks for your input guys youve helped hugely! :smiley:

Once again Rubjonnys info fixed my MFA oil temp.
I was curious also about the 160 for oil temp, I had a look for the sensor and found the top was damaged, the wire (black/green) was screwed onto the distributor as an earth by the previous owners. I myself had the distributor out recently as the hall sensor had failed. I also incorrectly hooked up the 'earth' wire.
I had to solder a spade connector onto the brass sensor stub as the plate part had broken off. I also sturdied it a little with a silicon hose over my bodge and some hot glue injected inside. It now works.
Thanks for info on hidden menus also. Now to understand all the info.
