Does not communicate with VTG

[Ziad]

Hello everyone,

Was just done reprogramming the GM3. Now my rear suspension is almost up, trunk is working fine, central locking system. Suspension error message still shows up every now and then...

While I was at the mechanic while checking why the ABS/4x4 inactive is showing in the dashboard, he mentioned that I got few bushings and balljoints to be replaced. He also said that one module cannot talk to the VTG.

Asking about VTG, he said that it's related to oil pressure in the differential since the car is over 160k. What do you guys think? and any idea about this VTG thing? first time i hear about it.

Thanks everyone!
