Problem with hunting Audi 80 1.9 TDI 1994

[RayH]

Hi.

I have cut the blue & white vehicle speed sensor wire on my audi 1.9 tdi.
Driving much improved, but still hunting on idle.

Any suggestions?

Can someone please help.

what engine code is this? 1z? is there a reference injector on this? two wires going to one of the injectors? check the resistance thru it? is it open circuit?

hi, had the filter on the end of the fuel tank sensor gunged up on my 80 tdi and it ran strange, question for you where is this blue/white speed sensor wire as i have a strange prob with my 80tdi ( see my post)

I have also Audi 80 1.9 TDI.It was in a very good condition,and is still working very well, during 2 years of using it we had no problems with the car.The engine works very well and is really very economic.Also very importatnt thing is that it doesn`t lose too much value after years..I think,two wires going to one of the injector.So,first you will check injector.

VAG COM it. It will tell you want's wrong and hopefully remove some of the guess work for you.

Plug it into VCDS and it will tell you what is wrong and save some guess work hopefully.
