Ok, whats the fuel pressure PSI at the fuel rail? Why where the injectors changed? those things last a very, very long time, Unless something got into the fuel tank? What are the DTC codes? Find a facility that has a least a VCID pc based...scan tool there acceptable for Audi's then you can know whats wrong in 15 minutes $100 is fair diagnostic fee. Regards

Injectors were changed as vehicle was smoking. .. had them tested and was opening at around 145 bar....all were leaking. .. cars been to audi and no faults or codes on there diagnostic machine.. mech ordered pressure valve yesterday. .says de is fuel coming to injectors but not enough pressure. ...will fit today...

now mech says de no power going to injectors... checked relays and all good.. told him to check crank sensor,,,,, any other idea please,,,
