Hello Chadahar,

I'd be happy to take a look at your 126 amplifiers, drop me a PM and we can discuss it further.

On testing the actuator:
Inside the box: VDO Cruise Control Actuator

If you turn off the car, but leave the key on, can you still hear the noise from the actuator?

During the test you should be able to hear the actuator whurring, it should sound relatively smooth.

Does this fix the surging that my cruise does and inter shutting off on it's own?

Yes....classic failing amp symptoms.

I still have a few of these amplifiers available. Most of the people who've asked or PM'd me about them neither of us had coding plugs for the vehicles, so most opted to just send me their current unit.

Looks like I'm about out of amplifiers as of right now. I might be getting some more in shortly so I'll update this thread when I know more.

In the mean time, if you're interested, I can always repair a unit that you send it. If interested, Pm me.

Here's the actuator test procedure:

You should perform this prior to sending in an amplifier or replacing one. This will help gauge the health of your actuator:

Just an update. I've got a new set of stock in! So if you're interested drop me a PM.

I've got 5x 005 545 05 32 units and 1x 003 545 09 32 unit.

Also, I've been successful at modifying the 003 545 09 32 unit to work in 300SD/SDLs. It becomes equivalent to 002 545 82 32.

Testing the Cruise Control's Voltage Signals:

The 14-pin connector contains a few connections that can easily be tested with a cheap voltmeter/digital multimeter.

These connections are crucial to the operation of the cruise system. As they provide the unit with power, switch settings and brake signals.

If any of these numbers do not match, you most likely have a wiring issue or perhaps bad cruise control switch:

Step 1)
-Put your meter into the Volts DC range (20 VDC if you have manual range settings).
-Ground the black probe to a known ground or you can use pin 12 or 14. One of them might not have a pin in the harness that is OK.

Step 2)
During this step you will need to place your red/positive probe into the pin below and if necessary toggle the cruise stalk in the appropriate direction or apply the brake pedal.

-Test for voltages:

Pin 1 - Power - Should Read Battery Voltage (~12V)
Pin 2 - Decel/Set - 0 Volts initial, Battery Voltage when toggled.
Pin 3 - Off - Battery Voltage initially, 0 when toggled
Pin 4 - Accel/Set - 0 Volts initial, Battery Voltage when toggled.
Pin 6 - Resume - 0 Volts initial, Battery Voltage when toggled
Pin 8 - Brake Pedal - 0 Volts initial, Battery Voltage when toggled.

If you have any questions feel free to PM me or post up.

Hope this helps!

-Kris

Am picking up a 300SDL and will need to address cruise. Am slightly confused by the pic. Where exactly is this? It looks like it's down by the pedals. So, on the 126, is the amp not accessed by removing the lower dash panel by the steering column? Thanks for any clarification you can provide for those of us who are "spatially challenged."

Shertex,

You are right, remove the driver's side kick panel and the CC amp is up near the brake pedal. It is the larger aluminum box.

Thanks....looks not quite as tight as the 124 location.

James - I have a working amp from an '85 300d and a sporatic one in an '85 190d. Do you know if they will swap?

Walkenvol,

The 85 190D uses:
002 545 16 32
002 545 82 32
003 545 86 32
005 545 05 32 + 005 545 11 32 plug

The 85 300D uses:
002 545 91 32

So unfortunately they will not swap.

If you're interested I can repair the existing amplifier for you. Drop me a PM on here or an email (jamesdean59@gmail.com) I'd be happy to help out.
