Ok, finally defeated it.
?
For those who need have the bouncing speedometer in the future, here is what I learned.
?
- Jack up front of van and slide under.
- Once you can see the exhaust manifold, you are far enough back
- On top of the transmission, next to the exhaust pipe, there is a fabric heat shield
- At the bottom of the heat shield is a slit that is snapped together.? Unsnap it and push it up the wire
- There is the VSS.
- Remove the wire bys sliding the top rectangle to the side.? It doesn't lift up as I assumed.? Once you have slid off the plastic lock, the wires unplug easily by lifting up.? The plastic lock is a U shaped lock that clamps the wires onto the sensor
- Unscrew the sensor and screw in the new one
- Attach the wires and push the lock back on
- Pull down the heat shield and snap the bottom
The Bentley was useless for this job.? I don't know how I got lucky and figured out the the lock slides to the side.? Next time I do it, it is a 15 minute job

SUCCESSFUL $7 FIX FOR RUNAWAY DOOR LOCKS!
A previous post linked to YouTube (https://www.youtube.com/watch?v=EaOL6XeX8JU) with the clever idea of installing a simple spring to solve the issue of locks going up and down uncontrollably—an issue normally requiring expensive hours of door panel removal and troubleshooting—but did not suggest a source for the spring. After a couple of trials I found a spring on Amazon ( $7.19 for set of 10) that works great! The inside diameter was slightly too small, but I could easily unwind the light gauge spring with enough force to widen it so it slides up and down on the knob easily and does not go down into the knob hole on the door rim. Furthermore, it was not clear from the video if this would fully restore the remote lock and unlock capability, so I was delighted to find out it does! (Not sure why it works, but I'll take it.)
?
One additional tip: To gain access to the van without setting off the runaway locks, simply disconnect the battery, use your manual key to unlock the driver's door (the only lock that permits this on my 2002 MV), then go inside to remove the passenger side knob, install the spring, replace the knob, reconnect the battery, and ... voila, full lock functionality restored in minutes for seven bucks and change!

Squeeze them together to unlatch the bottom edge.? Sometimes it helps to push the connector on a bit while trying.

Re: What to do with the Secondary Air Injection system (ACU engine)
Black and sooty spark plugs means you are not burning the gas………… The reason can be weak spark, bad plugs, too much gas, timing, low compression, plug wires, ?

There's a procedure in the service manual to check the fuel pump flow rate (~500ml over 30s at 43psi) but a simpler test that you do is to hook up a fuel pressure gauge and see if the pressure starts to fall below 36psi at idle.

Re: What to do with the Secondary Air Injection system (ACU engine)
Thank you guys for the for confirmation and reinforcement. I saw the van again today and did some more troubleshooting (new air filter, new fuel pressure regulator, check spark plugs, try to make sense of the vacuum lines).? When I got to removing the SAI, it was already disabled (a small plate blocking the metal pipe to engine head).? So all that fiddling with vacuum lines and valves was unnecessary, the system was dead anyway.
?
So here is what I know at this point:
1. when the Fuel Pressure Regulator and the Atmospheric Pressure Sensor (in the ECU) vacuum line is connected, engine runs fine at first but eventually dies at idle.
2. it runs best with FPR and APS disconnected, the vacuum line open and sucking in air.
3. spark plugs are black and sooty.
4. oxygen sensor is probably dead, disconnecting it wouldn't make any difference.
?
When I see the van again in a few days, my plan is:
1. change the O2 sensor,
2. change the fuel filter,
3. test the idle valve (it is vibrating to the touch with the key on, but have somewhere an old one I can swap in),
4. test the EGR valve
Anything else? Thanks a lot for your help!

If you have access to the wiring diagrams, they give the wire size in circular mils. ? /g/eurovanupdate/files/vw.t4.wd.48.pdf is an example.? Most have a close standard gauge.? If in doubt, use the next larger size. ?
Correction:? The sizes on the diagrams are in mm2, not circular mils.? Comparisons can be found .

Re: should I add wire to door harness repair
One thing some of us found years ago is that the loom is tie wrapped to a bracket just inside the cab.
Thanks Duane I heard others have just clip the tie wrap and let it hang. I'll see if one is needed when I do the install at fuse panel. Dumb question but do Germans use a metric wire gauge? I was going to use 18 GA for the small wires but some are even smaller, more like 20ga but not 22. I've already spliced in one wire using 18ga. Seems pretty close to me. Spencer

Whatever you can do to prevent bending will help.? One thing some of us found years ago is that the loom is tie wrapped to a bracket just inside the cab.? That causes it to bend instead of 'float' in and out.

Re: should I add wire to door harness repair
Mike, Justin thanks for the replies. My mirrors stopped working a number of years ago and now my windows stick in the up or down position- unless I open or close the door- depending on what mood they're in. I wish there was a new harness available but I bought a used one on ebay hoping to do a straight up swap out but the "new" harness has broken wires too so I'm going to rewire it and then swap out. I figured adding about 4" to the bigger wires might relieve some of the acute bending as they seem to be the most affected by the pinch. Recently I pulled the main switch and cleaned the contact points and now the driver's mirror works but the RS only clicks when the pad is pushed. After the rewiring and swap if things aren't working then it's hunting down a replacement main switch. Spencer

As far as adding extra length of wires when repairing, I guess that’s ur call. It’s tough doing wire repair work in that area without gaining a lil extra length, via unplugging the harness on either end or adding a lil extra wire,but then your doubling the amount of onerous connections you need to make securely. Last time I dealt w this repair the new complete harness for each door was still avail from the dealer so I went that route.?

Re: Weird problem with all automatic door latches
Same issue happens without power locks too. I have replaced the latch pieces on both doors. Poor design on the coil/wire. The spring idea is better than the o-ring option people have posted.

Re: should I add wire to door harness repair
Might I ask if you need this repair due to your door locks going up and down on their own? My 2002 Eurovan MV developed this problem recently and is unusable until I find a solution. I am told that it is a wiring issue but no way to tell which door has the problem.

That's what I thought until I got some of the hose.? You can use the old end pieces and check valve.? Don't even need any clamps.? Just make sure you don't put a kink in the hose.? Cost is about $6 or less for 2' at auto store instead of $87 (when they were available).? I buy a big roll, then cut it into ~18 inch pieces, more than enough for any model year, to sell to others (at cost, currently $2).? Cheaper at the store since I'd have to add postage unless we were meeting up (or you were getting some of the other stuff I keep around).
