Hi.

I have problem with Supply voltage for fuel injectors group A - Open Circuit

Car starts but runs like without one injector.
Removed injector cables, but this throws Injector fault.

Any idea?
Ecu injector driver problem?
How common is this?

No issues earlier, stayed overnight and in the morning runs rough.

Check/clean connectors for injectors. Trace and check wires for damage.
Swap injectors between cylinder to check if the fault moves.

Thanks, but there is only Group A fault. What injector are Group A and Group B?

I don't know these cars and engines by heart - need to know VIN or engine code to lookup wiring diagrams to know what is what.
Blind guess - Bank 1 / Bank 2 of a V-engine, seeing that you have 6-cyl, and VAG do not have an inline-6..

Solved, one of the injector connector have bad contact.
Bend pins and now works.
Thanks pupu144
