Audi A3 2006 1.9tdi oil light problem
 

I have just put an engine in an Audi A3, everything is working apart from the oil light when you turn the ignition on.

I have replaced the oil light switch and oil level censor but still no light.

Had it on a diagnostic machine and light can be switched on.

All cables have been earthed out and they all check out fine.

Please help.
