Cruise Control -- Completed
Before I begin to share my (less) knowledge 4 x Thanks to iichel
A big thanks to ciclo -- who had sold me stalks and wiring. Trust me (as mentioned in his listing
viewtopic.php?p=524890#p524890) not only stocks were brand new but it had PERFECT wiring. It had all wiring labeled, couple of pins for different connectors, fuses, cable joints, zip tie and fabric cloth. If he sells anything --- just go ahead and buy one!!!
Also I would like to confess that this post would be useful for low IQ people like me. Or lack of parts and tool support made me think each step multiple times.
SOS iichel and ciclo.
Disconnect Battery
First thing was accessing BCM. Best thing is get rid of front driver seat. Put on few pillow and you would have relaxed posture to fight with BCM and wiring.
But we did not do anything as such. As a result it was one person sleeping across passenger and driver seat and other looking from driver side door.
Mobile torch was not good enough so brought age old bulb and kept it on plastic lid at driver side foot.
Sometimes precise becomes biggest pain in ass but we can call it German Engineering!!!!
After removing BCM white connector with black tab with help of small screw driver. We need to push tabs and inside black connector is released.
Slide it up and down from either side from its grooves and we have all pin holes visible.
As mentioned previously eyes have become weaker and 6 eye balls, 3 mobile phone with zoom function -- finally made inserting pins a success.
That small click of connector locking was such a joy.
Then we moved our target to engine bay. Removed 6 Torx 20 screws of Air Filter top cover and moved it aside. This made accessing ECU less difficult.
Luckily ECU is just held in place with plastic tabs. Once we got it out we could access its big fat connector.
First is cut zip tie. Then remove the latch, pull it. Then slide purple color another glide mechanism. Wires every angle.
I am still guessing why these OEM wires have electric tapes. And why are there no dummy plugs in unused connectors.
Now was another test for our eyes. Printout of ECU pins showed numbering very easily. And actual ECU with wires is different story.
Don't laugh but 3 of us pointed 3 different locations.
Finally mechanic did the trick. He brought a thin, round long metal wire. Inserted it from bottom side where pins are numbered. And we found desired Pin number 45
I felt like why did I study this much.
On my request Ciclo had 2 possible types of connectors for ECU.
so next thing was which to use. iichecl confirmed in less than a minutes time. We oriented the notch and inserted it and again sweet sound.
This inserted wire from ECU had to be connected to wire which was inside cabin. We located a spot which has rubber lock and it was bang behind accelerated pedal.
Actual Rubber Connector Back Side
Actual Rubber Connector Front Side
I felt VW had kept this cover with precise hole just for this wire.
We put a sleeve on wire and then zip tied it and routed it towards ECU. Butt connector was too large for these 0.5mm sq wires. So we did electrician way. Open either ends of wire. Split the cores in half. Tie them with each other and electric tape. We made sure to have rubber sleeve before doing joint.
Zip tied it in engine bay along some other tubes.
Now the fuse box
Ciclo wire had a connector. So it should have been inserted in fuse box from behind. So we removed fuse box. But it was again German precision.
So decided to tap fuse from front. Many DIY had said tap Fuse SB11 with 5A. We had 10A fuse already there.
SOS -- ciclo replied with slot 10 with 5A fuse. So we tapped it and then connected battery.
Current fuse box status
Turned ignition ON and no Christmas lights.
Cranked engine and again no Christmas lights.
Connected to VCDS and did these two settings
09 -- Central Electronics -- Coding - 07 -- Long Coding Helper -- Head to Byte 17, enable Bit 7 which reads Cruise Control System (CCS) installed:
01 -- Engine -- Coding - 07 -- Long Coding Helper -- Byte 5 and enable Bit 5
We saved coding.
Drove out of garage bay. We toggled Cruise Control Stalk button to "ON" -- which is on Top side.
After 30 kmph we pressed set button (this is on end of stalks) and we got green cruise icon in instrument cluster.
But my friend who was driving felt we are decelerating. We pressed toggle buttons but no help.
Came back switched off car. Started it again. Checked if values were set correctly and they were.
Again drove and in quite crowded street could get cruise working. So may be it was working in first attempt but we could not verify it.
So here are many lessons learnt
- Open all doors of car and don't shut them
- If possible roll down all windows too.
- Open tail door and don't shut it. I had many tools kept in boot and it got closed by someone.
- Remove front seat if possible
- And if you are lucky then -- you would have people online on this forum and reply quickly.
- Anxiety is quite high and inserting pin in wrong numbered connector and then removing it would be another DIY
Parts used
- Zip Ties Black Colored
- Electric corrugated pipe. If you could then N10732401
Tool Used
- Many mobile phone to light up area
- Many mobile phones to click photo and zoom in to check numbering
- iFixit Tool Kit -- which could be handy.
