andi28,
You said "new jetta" as in A4 series?
If so, different model from what I'm used to.

DubRider,
"MFA"... Marine Fisheries Agency ?

What model/year is this car?

I know low level coolant sets of the coolant light,
do you recall if anything else does? Over heat/high
temp??

Did you try grounding the pins inside the coolant
level connector? One of the pins is ground, so
grounding both will be OK. Try grounding the pins
before turning the car on.

These VDO clusters are pretty good. Well built.
But like everything else in this world.... nothing is
perfect.

I'm not out to make money on these clusters I fix.
I usually ask for the cost of the parts and delivery
fees home.

Can you guys go a week without the cluster?

BobD

the car in question is a 96. temperature and coolant level is normal. i tested for continuity between battery ground and the brown wire for the resevoir and that checked out fine. i also tested the same battery ground and the probe inside the tank and it came out fine.
the lights comes on and the mfa don't work, when the light stops flashing the mfa works again.
BobD the mfa is the imformation display used on vr6 models.

It may sound wierd, but I've yet to see a cluster with the MFA. Have a picture.

You've given some new info.
"when the light stops flashing the mfa works again"

When I see the flashing coolant light, it's not on MFA versions. And it flashes all the time!

I can only guess the VR6's up here don't have the MFA or they are very rare. Like I said, I've never seen one. What do you get on the MFA? (OAT, , , )

Send me some photos?

my Jetta is a 99, Jetta 4 (it was known as a 'new jetta'). The same model was built from 99 to 2002, when it got a fecelift.

andi28,
I've yet to play with an A4 series.
The speedometer/Odometer can be an easy fix. What makes it easy is having a digital scope.

Basically when the speedo isn't working, you need to know if the sensor is sending the pulses. With a scope you would see, or not see, the pulses. This would basically tell you if you have a bad sensor, or cluster.

In all of my VW trouble shooting years, I've not really run into "wiring" problems. Unless the wire is at the end of the line and it's a bad ground due to corrosion.
VW makes good harnesses. Unless someone has tampered with something.

I have not worked on an A4 series Jetta, so I'm not familiar with how that cluster works.

hi. i have a related problem, but different.
the speedometer in my '02 jetta (4cl.Non-turbo) just stopped working today. no needle shaking. the odometer also does not work. but the tach DOES work. the engine light came on, too.

what's up? can anyone help?

That is exactly my problem, sppedo/edo not, tacho yes. engine light on - yes.

Thanks for the others. Where is the speed sensor, so I can check the pulses coming?
Thanks

juju,
You have an A4 series cluster.
post here:
http://tech.bentleypublishers.com/forum.jspa?forumName=volkswagen.a.a4

The shaking that is talked about here in this forum is for a completely different type of cluster than yours.
Here we are talking about Gen3 or A3 series Vw's

Today I received my first MFA Cluster.
It actually belongs to Flex from this forum.

Because I don't have the sensors the MFA is trying to read, the screen displays zeros for most of the items.
Still, pretty cool. Would like to see it in action.

"All hail the cluster king". Received my repaired cluster (gen3 vr6 golf w/MFA) today from BobD. My speedo and tach were cutting out intermittently but all other gauges were functioning correctly. Put in the repaired cluster and i've been driving for hours without the slightest glitch. Normally it would have cut out about two or three times in that time frame. My cluster works like new. If you've got cluster problems like i've had listen to BobD, he obviously knows what to look for and how to fix it.

thanks again BobD

Hey Flex Thanks...
You've got the cluster back in already. You don't waste anytime. I'm guessing you got it on time today. I told the courier to have to you by noon!

Less than 24hours ago your cluster was in many pieces in my lab!
I guess it pays to be just down the 401.

simanster,

gdub22, had the same problem as you. And I fixed it.
gdub22 had a type of problem that is quite rare. His was the first of that kind I got to see & fix.

The other type of problem which involves both the Tach & speedo I fixed on a regular basis.
I also fixed Flex's cluster. He had the tach/speedo problem.

Flex lives UP the 401 in Brampton, and I live down the 401 in London.

Can you answer the following questions:
-You have no speed signal at all? The needle sits at
zero at all times?
-Is the Tach operating as expected?
-Is the odometer adding up?
-Are you finding the fuel gauge moves around with the
vehicles speed?

Perhaps you can steer me in the right direction?

94 Golf 2.0L 5spd.

No speedo.
Tach is OK
Odometer accumulates.
Coolant/Fuel gauges OK.

My cluster has the removeable motors for Speedo and tach. (Socket mounted, not soldered to the board) I've swapped out the speedo motor with no luck. If I move the speedo needle by hand and apply voltage, it stays where I put it and returns to zero when voltage is removed.

Sanchez,
I'm familiar with the motors you are refering to.
You have the first gen of these VDO clusters, I think it ended in 94.

1. So when you swopped the motors, the cluster operated the same?

How are you applying the voltage? Are you just giving the windings 12V DC? If so, the needle should stay where it is until you remove the voltage. This is refered to as braking.

Let me know,
BobD

The "new" motor in the cluster made no change. Speedo would still not operate at all. No flicker when the ignition is turned on.

the windings 12V DC? If so, the needle should stay
where it is until you remove the voltage. This is
refered to as braking.

It was closer to 9V, but yes. That's what it was doing.

I'm starting to wonder if it's a wiring problem in the car. I've been looking at wiring diagrams and it appears that the cluster gets multiple feeds for vehicle speed. One is directly from the VSS, and the other travels through the cruise circuit and ECM before it gets to the cluster. I'm guessing the odometer takes the "direct" feed and the speedometer takes the secondary one.

Sanchez,
But you did not try switching the tach & speedo motors?
Or are you refering to the new motor as the tach motor?
I'm just curious to know if the speedo motor worked in the tach location.

9Volts, yes the stepper is doing what it's suppose to.

If your odometer is adding up, then your speed sensor is fine.

The speed signal actually goes the other way.
The speed signal comes from the sensor through the cluster to the ECM and Cruise Control.

I would say your problem is the cluster.

hey bobd just picked up a 97 vr6 cluster that has the same problem, the needles just bounce, if u could email at efrench11@yahoo.com i would like to know how much to fix it, i am not worried about time. for i am not driving my car at this point i am only adding parts for the winter time. thank you. the cluster is a vdo, not the mfa which i would like to have because they are much cooler looking at night when u light them up.

Hi BobD,

I am just havng the similar cluster problem on my 1995 jetta III GL. Both the tachometer and speedometer don't work some times. When one works, both work. I do observe that the tachometer needle vibrating around zero when I turn the key ON (then it does not work). When I turn off, the needle keeps vibrating for a while before it stops. The odometer works fine.

Could I send my cluster to your place and have it fixed? Thanks very much. My email address is daglas_long@yahoo.com.
