How to locate ECU number?
 

I can't get the rubber covering the ECU to come off. How do I do that? There is a number on the rubber itself, it's 8N0 971 905. Is that the ECU number? I am trying to get it for Pete from Stratmosphere.

Plus you'll need the last letter, "K", "N"...

Hmmm...interesting
 

My ecu number is 8N0 906 018 L. I thought the first 8 numbers are the same for all TTs. The only thing that's different between a 180 and 225 is the last letter. I thought the last letter corresponds to the engine code. For example, "L" corresponds to the engine code "AWP", etc...

The difference explained...
 

I live in Australia...hence my car would be of a different spec than yours. It's a TTR 225Q though.

Where about in Oz are you?
 

Would be interested to see the difference once you put the chip in!!!
