A small project

[ScottD3]

Its an idea i've been toying with for some time and been working on since Saturday.
Thanks to Byzan for the clocks I can butcher and thanks to TonyA4 for the clocks to test (I've not blown them up yet).

I want to fit facelift clocks to my Pre-facelift car.

There is changes in the cable layout, different plugs and different sensors needed. Forgetting the sensors for now, they can be added later. I made a loom up out of facelift plugs and wires and the sockets from the back of a pre-facelift clock. I got pictures for that, which I will post up later.

I think I got most of it working but I'm stuck on a couple of little bits.

What works:=-
Door sensors. not all but some. thats down to me not wiring them in.
Dash lights. The clocks light up when I turn the light on but they don't when I open the door or turn the key, like pre-facelift lights. Is this correct?
Voltage.
Fuel.
DIS control.
digi displays.
Dimming the display.

Thats all I can test at the moment as I can't start the car to get it up to temp, speed or revs.

What does not work:=-
Its moaning about some sensors, oil, breaks and I think thats it. I can't really tell cause the screen has missing pixels.
The immobilizer, I need to get this removed, codded, changed. I'm not sure what.
Really important, I can't set the time. I push, twist and nothing happens. I think it goes in to a test mode at some point.

Any ideas, pointers, helps or any thing would be great. My main aim is to get it working and the car driving. I will worry about the oil sensors and break sensors at a later date. I think thats the sensors thats missing.

Here is some images (If they don't work, let me know and i'll get some photobucket ones up tomorrow)

Good Job! so far

Thats looking good Scott.

 

[Oranoco]

248,000 miles????? **** me! Mine's barely run in with 148,000 lol

Seriously though mate, nice bit of work there. Will be interested how you get on

 

[ScottD3]

First thing I need to sort out is to remove or recode immobilizer and get the engine running.
does any one have ideas about this?

When you attempt to start a car with no key and immob is active, does the rev counter not work?

how do you set the clock?

left stalk on the clocks, what does each left, right and push do?
right stalk, what does push do?

 

[LeeT]

im very interested in this too, keep at it

 

[ScottD3]

has any one got the wiring diagrams in digital format for the b5s?

 

[Broken Byzan]

i can do, but be tomorrow now as i need to swap PCs over to my xp box for my full etka. Which bits you need?

Want to double check the wiring on clocks.
The pin outs I got seem to be ok but there is a couple that I confirmation on.

To set the time you PULL the left hand pin iirc?

Immo is both part of the ECU and the clocks. You need the SKC from the cluster which you can extract with vagtacho, then use vagcom to pair the Cluster with the Engine ECU.

You may find your older engine ECU wont pair with an IMMO3 cluster, but all you can do is try.

Oil sensor uses a combined PWM signal for temperature, level and quality on a >2000 facelift cluster. You'll need to swap the sump for a later one with the level sensor, and connect the wiring appropriately. The dash will permenantly display "SENSOR" and an oil symbol without it.

Pad warning can easily be turned off by shorting the appropriate wire to earth.

Pinouts are as follows:

thanks I'll try the clock again tomorrow.

PWM signal?

I might fit the sensor but put it somewhere else till I swap the sump over. I got a leaking sump at the moment, so its something to add to the lift for when I do that.

Klappe says he's got what I need, so hopefully he'll be over this weekend and we can turn the pads off and attempt coding.

these clocks are from tonyA4, I also have the key from the same car as these clocks.
I might try that before coding but if the immob code is in the ECU and clocks, It will be trial and error.
There was a forum post about removing the immob from the ECU, I'll dig it out.

Thanks for the pin outs. Do you know if the EU pin outs differ from the yanks? I got two pin out diagrams from the states.

PWM = Pulse Width Modulation

Heres the maths

Make more sense now?

Looking good though scotty well done. sorry ive not been much help, just not had the time lately.

Could I make a PWM circuit and use that?
As a tem fix, to remove the error?
I'm not sure how the sensor works, so that idea might be stupid.

 

[Arrkon]

It would probably be easier to fit the later model sump and sensor and wire it to the cluster... as i suspect finding out what the output of the sensor would prove difficult...

 

[ScottD3]

i've checked the pins out I got from the states with the pin out Aragorn supplied and there is slight differences.

There is a couple of changes over two plugs.

First is the 98 Green plug.
The yanks don't have any thing in Pins 2, 4, 17 and 29.

Pin 2, Transponder 1
Pin 4, Immobilizer
Pin 17, Transponder 2

I assume the above pins are missing on the yanks cause they did not have immobilizers in pre-facelift A4s?
These pins are the same on 98 and 2000. Which is good, they are in the right places.

Pin 29, Terminal 58d (external dimmer potentiometer)
Not a clue what this one does. There is a couple of them on both 98 and 2000 in the blue plug but nothing in Green. so Not sure where this one has to go or even if its needed.

Next is the Red Plug on 98s.
Pin 17, Glow plugs.
I'm not sure where this one goes.
On the 98 Clocks there is 2 Glow plug pins
Blue
13 - Glow period warning lamp or CAT
Red
17 - Glow plug relay (on TDI engines the low-voltage monitor in the instrument cluster is disabled while the glow plugs are activated)

On the 2000 clocks there is 1 glow plug pin
Blue
13 - Electronic throttle / glow period warning lamp

Where does the Red 17 go?

On my current loom, the glow plug light was acting runny, It would flash at first and then stop.

 

[ScottD3]

It would probably be easier to fit the later model sump and sensor and wire it to the cluster... as i suspect finding out what the output of the sensor would prove difficult...

That is the long term plan but short term to get the clocks up and running for now would be to trick it in to thinking it has a sensor.

 

[aragorn]

It'll be FAR easier just to fit the sump and sensor than trying to fool it.

As you say, yank cars dont have immo.

58d is the dimmer output. One of the dials on the cluster dims the cluster, and also sends the output off round the car to dim the illumination on the dash/switches etc.

For the glow plugs, i'd leave 13 connected to 13, and ignore 17 as its not mentioned on the 2000 cluster.

 

[ScottD3]

Bit of a update.

I went out and had a play with the key that came from the same car as the clocks.
It never worked, never thought it would but worth a go.
I need a copy of Vag Commander and VCDS to get theses clocks coded and see if they will work with my ECU. If this does not work, I will have to look in to other options for immob.

I plugged the original clocks and it still works, so thats good.
Got some heat in the oil and temp gauges to see if they worked on the new clocks and they do. WooHoo.

What works:=-
Oil Temp
Water Temp
Bettery voltage
Fuel Gauge
Clock
Door sensors
Lights
Dimming
DIS controls on stalk

What's not working or unable to test:=-
Speedo
Rev counter
Odo Meter
DIS for MPG and such
DIS for auto boxes

I think that's it. Alot of the above can't be tested cause the car won't start. Once I can start the car and drive it i'll be able to test them.

Aragorn, TonyA4 is sending me up the sensor from his breaker, so i'll be able to wiring that in to test it.
Every thing else is waiting on VAG commander or vagtacho.

 

[Foxmeister]

Good stuff mate, keep at it!

Nice one.

Trouble is I only need to use it once so a bit begrudging spending money on a one time use device.

Want to post me yours?

 

[ScottD3]

Heres a couple of semi good pics

Oil and temp gauges at the same temp when I took the old clocks out

parts of the loom I made

I do hope Byzan never wanted theses clocks back.

Is there any real benefits in changing to the facelift clocks? What extra do they offer?(Apart from slight cosmetic differences)

Looks really mate.
Oil level sensor.
Door opening warning.
Digi clock with date.
and erm.........Thats it. Thats all I know.



Has any one heard, done or even know about the emergency start you can with the clocks?

 

[Arrkon]

E Start with the clocks? elaborate?? i'm intrigued

 

[Broken Byzan]

there is a way, but it only runs for 40 mins iirc.

I may know where there is an immo emulator available for immo2. Very possible you could use it to tell the ECU all is fine so the car runs, even if the dash says no.

 

[ScottD3]

E Start with the clocks? elaborate?? i'm intrigued

in short you attempt to start the car with a key, use the clocks to enter the 4 digit SKC number in to the clocks and the car will start.
I'll send you the link later mate.

 

[Broken Byzan]

I do hope Byzan never wanted theses clocks back.

Nah it's all good, although did i leave the adjustable pot thingy soldered onto the back by the LCD?

That would be cool.

Am I right in thinking that my pre-facelift cluster is IMMO1 and the facelift cluster is IMMO2?

I found a thread about people swapping the IMMO chips over on the ECU to beat reprogramming.

 

[Broken Byzan]

facelift is possibly immo3, there seems to be some confusion as to which it is

You also get infotainment can-bus, so if you wanted to retrofit RNS-E or Audi bluetooth etc.

With all these culster swaps you don't have a spare remote key you would sell? I need one for a little project.
