Yup, the same guy is me. My bad.:D

You mean there's two things? Thought it was just the module. Am I supposed to send this guy both?

I would contact him and ask. I think our 86-88.5 3.2 brothers have different CC set ups.

The Servo is in the engine compartment and the module is in the frunk behind the cardboard shield.

Already on it, email sent [emoji106]

NO!! Your problem is an aging CC module that won't hold speed not a defective servo!
In all the threads on CC in this forum, I have never encountered one where the problem was a bad servo. Perhaps a servo that wasn't hooked up correctly to electric wiring or vacuum may have been a problem, but never a bad servo.

86-89Carreras use exactly the same system with vacuum servo and module, with two exceptions. They use a 14pin module vs 10 pin, and the module is relocated inside the car under the dash. It operates identically.

Correction: '88-'89 Carreras started using an electrical servo in lieu of the vacuum servo. Basic operation remained the same.

^^^ there you have it :-)

CC module repair
 

I will relate my experience with repair this year. I had Kris or Cris (the new guy on the block) repair mine and it did not work when returned. He did warn that he cannot test his repair. I had already bought a non-working back-up module which I sent to Beckman here in NC who do repair and test of modules primarily for Mercedes. They confirmed the Porsche part number is one they can repair. They have a big place and charge real but not stupid money and guarantee for a year. That unit did work when returned and is still working so my vote is do it right and spend a bit more. Repair time was one day plus shipping, easy. You pay when job is complete with a CC.

Cruise Control trouble chart has a huge ERROR on checking the clutch switch!!
 

I have posted this before to help save folks from frustration and unneeded extra work while troubleshooting cruise control problems, and since we again visit CC problems, it bears repeating here. The Bentley manual has a glaring error in the CC troubleshooting chart as pertains to checking the clutch switch. The Bentley chart will lead you astray and cause you untold frustration by letting you think you have a bad clutch switch. By the way, it's really not Bentley's fault, they simply reproduced the chart that appears in the FACTORY manual, which is also wrong. Anyway here the info:

And the burning question is, how much is: "real but not stupid money"

I think it was like $200 plus return ship plus tax in my case. Vs $70 plus shipping as I remember to Kris. Think the initial comment is that its more now. They will tell you the cost when you contact them, very straightforward. They answer the phone, its a real business.

Oustanding! Thank You Brother Uwanna :D SmileWavy

This wouldn't have anything to do with speed bleeding off though, right?

Correct, has nothing to do with speed bleeding off.

I used the Ebay guy before when his price was $80. He does do excellent work, tests the unit, gives a lifetime warranty and pays for return shipping. The two he did for me are still working perfectly after a couple of years. My only concern was the price increase to $190.

I have personally repaired four units myself with a removal of the lacquer type coating on the back of the PC board with acetone, reflow of ALL the solder joints and replacement of some bad capacitors. One caution, you must use a very pointed soldering iron and make sure none of the tiny connections "bridge" to another connection with stray solder! It's quite tedious work, but very rewarding!

Lol
 

Yep, that would do it for me too.

Yeah, I'll just pay the $80 LOL.

Minor quibble, they aren't exactly the same in this date range. My 88 has an electric servo, not a vacuum servo.

I stand corrected, forgot about the switch over to electric servo for '88-89. With the exception of the servo, the operation is still very similar.

I parted out an 87 years ago. I think I have the electric servo still if you need it.
