E-diff manufacturer
 

Just wondering - Does anyone know if the e-diff a haldex unit?

The E-Diff is made by GKN Driveline in the UK.

It's their "Electronic Torque Manager" product.

I'll sell you my old one for cheap. After replacing it I discovered that the solenoid spring no longer works on the old one. That's why I had the e-diff error.

Basically, the e-diff has a solenoid in it. When it works normally it clicks when you energize it and it clicks again when you de-energize it. On my broken one it clicks once when you energize it then it clicks no more. If you reverse the polarity is clicks once, then no more clicky. Each time you reverse the polarity it clicks once. Clearly the spring in the solenoid is broken. I might try to fix it, or I might sell it cheap on eBay.
