Cabrio trip computer/Autocheck question

Inexperienced Joined: Feb 06, 2015 Posts: 29

Hi guys. First see my introducing that I move to here
I am trying to install trip computer with Autocheck.
My first question is are all the trip computer modules equipped with the Autocheck, or just some of them? Someone told me not all have it.

Also is there a difference in the part number for UK and USA cars? The reason - the USA gallon is a lot different than the Imperial gallon - google it
In ETKA it shows one part number for UK/USA and all athoers who use miles and gallons and one for EU standard. Am I thinking right that ECU gives the correct info to the trip computer and actually makes it shows the correct numbers?
I found a few trip computers with the wiring and the wiper switch in ebay, but how do I know if they have the AUtocheck?

thanks

From memory I'm pretty sure there's a selector switch on the back of the instrument cluster that allows you to select what the display should show...

Autocheck was on all the cars ive had that had a trip computer. There is a difference between UK and foreign displays.

Yep, some trip computers had autocheck, some don't - thats what my research showed. But all autochecks had trip comp.

THe usa and UK versions are the same I found. Only europe one is different but only because of the external symbols for liters and Kilometers. But if you connect Europe to UK/US car it will show up correct numbers but not matching the liters and gallons. Its confusing but thats what it is.

At the end, UK trip computer matches US trip computer because they are the same, only you have to switch that button, otherwise it will show up imperial gallon.
thanks to everybody Smile

Not quite correct, some cars had autocheck, but no trip computer. There is a coding plug which dictates the display from memory and the autocheck module has soldered jumpers to set it correctly. Are you planning on installing autocheck? I have and it's a lot of work, there is quite a lot of wiring involved to make it work correctly, to give you an idea here is my car in the process of doing the wiring.

I was fitting a few other things at the time so it is not necessary to go to quite that extent, but you'll need to run wiring from the front to the back, change the washer bottle and pump, fit bulb monitoring units etc. There is a lot involved.

Yep, I know, thanks for warning me. I am about to put a manual gearbox and new engine, together with removing the dash for new heater core change. My heater core is ok, but I may know for the heater box problems. My car is Florida car and never ever needed heater, so thats why no one ever cared, but I moved a little far North and the heated seats are not enought.
So the autocheck will be installed at that time.

For the washer bottle - I know it. I have the bigger reservoir in my car, because I have headlight washers and I need to make one extra hole for the sensor-type pump. I did a hole and everything is now perfect. The bracket of the original non-sensor pump has some space inbetween , and this space is actually left for those sensor pumps. (usa models never had autocheck, only the coupe quattro)
here is pic of my work

I was wondering does the coupe quattro reservoir from a car with autocheck will fit in the cabriolet?

Sounds like you know what's involved. I'd strongly recommend getting all the plugs with a decent length of wire from a donor car along with the bulb monitoring units and warning buzzer. I got my washer bottle from a crashed S2 and it was just a straight swap, I'm not aware of a difference between coupe and cabriolet though.

WHat monitoring bulb and buzzer? I thought its all inside the autocheck unit... or?

Thanks a lot. I have some kind of guide and it should help me somehow, but I appreciate the detailed info you gave me Smile

ok i am on the way..I took of my steering wheel and cluster, installed the autocheck in the cluster and now I have to do the wiring. The wiper stalk button is on its place and all the wires to the small black plug on the back of the unit and what left is the 26 pin connector which I am haveing problem find which wire goes where.
As far as I know I am missing brown(ground wire) on 16th pin..
pin 3 is for windshield washer container sensor, then red and grey one are for the bulb check, which all for now I will ground so it shows OK and later I may consider installing them..
but for now i have to figure out how to wire it
