Approaching Haldex 4-Motion

Hello, I was wondering if anyone has ever read and decoded the Haldex IDs before.

Haldex has approximately 1100 products, of which about 300 are electric.

You need to be a little more specific.

Okay, sorry, I forgot. It's a Golf 5 GTI conversion to all-wheel drive. The rear axle is from an Audi S3 with the Haldex system.

You're not making it easy.

Which S3 model, which ESP variant (switchable/non-switchable), which Haldex generation (4 or 5) with or without torque vectoring?
