Passat Coding changes

**Swallowtail** · 10-10-2009, 11:05 PM

I've made a few coding changes using VCDS to my R36:

1. Enabled auto-closing of sunroof and windows if it rains - follow these instructions: http://www.my-gti.com/204/volkswagen...ws-and-sunroof

2. Enabled hazard flashers on emergency braking.

3. Fixed trailer controller coding so it doesn't give me false bulb failure warnings.

4. Made the speedo more accurate - now reads 105 at 100kmh instead of 108.

5. The alarm now does a subtle little chirp (very subtle, almost inaudible...) when you unlock or lock the car.

Changed a few other little things I came across too. Very cool.

Handy tool that VAGCOM...

How did you go about calibrating the speedo. Info would be good.
After coding your auto close windows, did you verify its operation? After re-coding mine it didn't function.

How much is VAGCOM and is it worth it?

Speedo - using the CAN bus speed (press AC and up vent at the same time, rotate the L/H temp dial until the display reads 19 0, the right hand display shows the CAN bus speed, which is pretty accurate. Apparently it's what the odometer goes on). See how far out the speedo is! In VAGCOM go into the instrument cluster controller, go into Coding, and see what the last digit is. Mine was 6. That's a range up to 7 (not 8 like VAGCOM thinks) - the higher the number the lower the speedo will read for a given road speed. Going from 6 to 7 gave me a bit more accuracy.

Windows - yes it works, tested it with water on the screen. There are a couple of steps, not just the obvious one - you need to code the Rain sensor with a different value. See the link I posted to Maverick's site for info.

Cost me about $400 I think from memory. I think it's worth it - I've done the above, cleared error codes from the after market stereo install (they removed the VW amp, but the car was still looking for it) and have coded my Bluetooth install with it.

And a couple of other people have borrowed it and used it to. One of them was to see what error codes were on a 2nd hand Passat they were buying.

Swallowtail, I am keen to do no.2.

Here is one for you, can you adjust the winscreen wiper operation.
When you clear the screen (and headlights) with a spray of water, it normally wipes about 3 times, however some of the newer vehicles do a 4th sweep after about 3 seconds. That is a very cool feature that I would like to have recoded.

Can you activate this, happy to discuss, meet up etc!

Where did you pick it up from?

I'm looking at getting one, as I'm thinking of leaving where I am, and going mobile next year. Somehow, I don't think I'll be able to sneak our VAS5052 out under my shirt :p
