Have a 2016 a4 2.0tdi ultra se.

Car won't start,it's not 

Starter motor or relays and no wires cut.

At a loss with this one 

Is it cranking? 

Are there any lights on the dash? 

Could it be a dead battery? 

Cranking fine starter motor was bench tested and relays replaced,

Wires check nothing broken.

No lights on dash board to state any problems.battery has been test and is putting out full voltage.

Hi you need to get the vehicle plugged in and read for codes. Could even be the cam timing has slipped when was the belt last changed?

Steve.

P0512 was only code it was for starter request circuit.

Timing belt water pump done 2 months ago by audi.

It's with an auto spark so hopefully get to the bottom of it at some stage.

He's thinking it mite be proble with ecu.

Hi there you go, you have just unearthed a potential problem and cancelled out the one with the belt kit, please post your outcome as it helps others who may have similar problems and won't leave anyone else reading this wondering, I wish you the best of luck.

Stevey did get to the bottom of your fault? Mines doing the same and same fault but eventually starts

 

My old Chevy Cruze did this, bought an A4 for that reason
I took it to 3 different mechanics and none of them could figure out what was wrong.
Don't wanna scare anyone, but good luck.
