I posted this in the TT forum and didn't get much help or didn't find any solution.

I have a TT 2001 and i just purchased the radio from a TT 2002 who has the cd player in front.
I juste plug it like my old one was done. Since then, my radio dosen't stop in the same time as the car and there is no light in the radio.

Seem that my radio created a short and nom my windshield washer pump dosen't work ( I tested it and it work great)

Thansk for your help

 

They just have a permanent live feed and use the CAN-BUS to tell the radio that the ignition is on. I'm guessing that your TT doesn't have the ignition on coding on the CANBUS so I'm surprised the radio works at all. Does it switch itself off after an hour?
Not sure if you can VAGCOM it to rectify the problem.
There is no relation between radio and washer pump so that problem has to be unrelated.

 

Hi,

I didn't check if the radio turn off after an hour. I have to turn it off manualy. I will re-instal my old radio to see

Note 1: the wiring harness bellow is completely optional but I am engineer (so **** by nature), so I did it this way.

Note 2: all of this is based on a car with out the factory NAV system, if you have the factory NAV system then it changes slightly (not a lot) in the fact that you do not have to remove the dash cluster as stated below. You would just have tap into the CAN-H/CAN-L lines at the NAV control unit (or the dash cluster if you like).

Note 3: Using a VAG tool, make sure you have software version D26 or later on your dash cluster. If you don't I do not think this will work.

1. Got a Concert II radio (which was harder then it seemed), I found a salvage company, Al's Auto Wrecking (619) 992-1670 )that will sell them for right around $200.00. Make sure that they send you the connectors with the radio.

2. Found an Old (non-working) Concert I on eBay and removed the female portion of the connectors.

3. Dismantled the connectors (from step 1), using a turkey skewer and a lot of swearing, and put new pins/leads into it.

4. Soldiered the connectors (from step 1) to the female block (from step 2) making a custom wiring harness. When I did this, I broke the CAN-H &amp; CAN-L lines (Coming out of the Concert II) out to bare wire, to be used later.

Note: like I said above, I am **** by nature so I made the above harness to pretty much simply break the CAN-H/CAN-L wires out without having to modify any of the Cars existing wiring. If you wanted you could modify (cut) the plug 1 on the radio and splice into the wires.

6. Remove the dash cluster

7. Disconnect the Grey connector from the back of the dash cluster by lifting the red handle on the connector. This will literally lift the connector off of the dash cluster.

8. Take apart the connector by first sliding the Red end cap off and then (gently) pulling out the white interior connector (when I get my friends digital camera I can take some pictures of this stuff). If you are wondering, the grey part of the connector is a sleeve that slides over the actual connector. IT comes apart very easily so don't force anything.

7. Install the CAN-H line (from the radio) into pin 5 of the grey connector. The pins are already there and are self tapping; all you have to do is push the wire into the pin and make sure that it cuts the wire's shielding.

8. Install the CAN-L line (from the radio) into pin 6 of the grey connector. The pins are already there and are self tapping; all you have to do is push the wire into the pin and make sure that it cuts the wire's shielding.

9. Put your dash back together

10. Using a VAG tool (or VAGcomm) and follow the enclosed URL of how to set the adaptation channel for the instrument cluster.

Now your car should be converted over to CAN (instead of using the Audi 3-wb ) so things like the power control via ignition, illumination, center display should work.
