Hello All,

I have a 2005 passat b5 1.9 tdi 130
Just fitted Allard egr bypass, and emissons workshop warning comes on.
I understand that the ecu has to be rewritten so it does not look for exhaust gases.

I am based nr Swindon. (J16 M4)
Can anyone recommend a company that can help with this?

If not, anyone know of good people in Birmingham area?


Kind regards

David
