Troubleshooting Freewheel Lockout

[86 Syncro]

Ok, still trying to figure out why I’m not getting freewheel lockout in reverse. I checked all the vacuum lines yesterday, and all are connected, and don’t appear to be blocked. Also checked fuses, and none are blown.

Next I was going to start checking the electrics. Would I be able to simply check for continuity on the 2 wires that go to lockout solenoid on the rear diff?

If I am correct, if I don’t get continuity in reverse, I will either need a new reverse switch, or relay. And if I do get continuity, that means that I need a new lockout solenoid. (which I assume is really expensive)

man, almost 2 days and still zero responses? I didn’t stump you all, did I?

I would think that (as usually happens) it is the reverse switch (on the gearbox) that is giving the problems, they do wear out you know, even if it has taken 25 years!

They are no longer available from VW but I can rebuild your own switch for you with new springs etc for 30 euros + postage

With regard to the response time,

Please Note,

That we all give up our leisure time to try help each other out, some of us (as you do) have to work, some of us (like myself) are retired, however most of us do have a life apart from these forums, which sometimes takes precedence over anything posted on here,

Be assured that we will all do our best to help you out, but sometimes you just have to wait untill the right person comes along!

I apologize if I came across as being rude or impatient, Chris. That wasn’t my intention.

I guess I’ve just gotten spoiled with getting quick answers over on Vortex… That and I’m kind of in a hurry to get the issue sorted, since it can start snowing here as early as October and it looks like temps will start dropping below freezing in the next week or so.

Anyway, being that my Syncro is currently my daily driver until I get my Golf III sorted out, I will have to wait until then, or try and find another Syncro in a scrapyard somewhere (HAHAHAHA!) before I can send you the switch.

Is it safe to assume that since you didn’t offer it, you are no longer able to do switch rebuilds on an exchange basis? I would be willing to throw you a few Euros more for that.

[Chris S]

Apologies not necessary, as no one took offence.

I can do the switch exchange if you like? As long as you send me your old switch when you have swapped them over.

I have just seen that 1 of the switches are still available at

http://www.volkswagen-classic-parts.de/bestand/bestand_int.pl?lang=en

p/n 191919823D 7 pin – 191 919 823D – switch – Genuine Part € 44.01

P/n 191919823B 8 pin – 191 919 823B – switch – no longer available

will the 7 pin switch still work? I’ll have to go out in the morning and look to see which one I have, unless you know of the top of you head….

I can order from VW Classic Parts right through my local dealer, so this is perfect! I didn’t think to check with them since the switch was dropped without replacement 5 years ago, I figured they were all gone.

If it turns out that they no longer have the switch, i will let you know.

[Chris S]

If your new switch works please will you send me your old one, as these switches are getting very rare & not every one is suitable for rebuilding.

hmm. wonder if the 02C edition of the switch still exists?

[Chris S]

The 4 pin version 02A 919 823B was dropped without replacement on 01-01-2007

There is now only the 2 pin version available 02A 945 413C – For the 2wd Passat

I have both switches here

[Housey]

i’ve got 4 pins which i guess is standard on the syncro

Sure, no problem Chris.

Does anyone know the what the extra 3 pins on the 7-pin switch are for? What trans is this switch from? Since electrical parts are normally non-returnable, I’d like to know for sure this is going to work before I drop 45 euros on it.

[Chris S]

The pins we are talking about on the 020 Gearbox (which you have) are not external pins, but are internal

p/n 191919823D 7 pin – 191 919 823D – switch – Genuine Part € 44.01

P/n 191919823B 8 pin – 191 919 823B – switch – no longer available

both switches will fit the plug on your wiring harness.

The 2 or 4 pin plugs mentioned below are only for the 02C gearbox (Rallye, Passat G60 Syncro) & they are not compatable with either your gearbox or wiring harness

02A 919 823B dropped without replacement on 01-01-2007

02A 945 413C 2 pin version available – For the 2wd Passat & supposedly for the later (93 on) Golf & Passat VR6/TDI Syncro models
