Just bought new Audi A7 3.0Tdi biturbo. After 4 days the ADblue indicator light started to blink and told me that I had to refill and would not be able to restart within 1000 km. Went to the Audi dealer, but they could not find anything the Adblue tank was full. After 2000 km the Adblue started to blink again. Audi dealer want to replace the pump and injector! Quite worrying for a brand new car!!!
Anybody else who has the same problem on the Audi A7 2015?

Haven't heard this on our 2014 Audi A6 TDI or among others here. But over on the Mercedes ML350 bluetec forum, ppl had that problem repaired with the adblue sensor and pump and the issue went away. Its a quick fix and I am sure you will be fine once its done. This is also a very rare situation. I wouldn't worry about it too much till then.

Thanks for your reply. My Audi dealer came to pick up my car today and will replace the pump and injector. It seems that the Adblue is also needed to clean the carbon filter so they didn't want me continue driving it.

My '09 S line Q7 has been at the dealer 5 times now for a AdBlue light issue. Apparently there are many AdBlue counter sensors throughout the vehicle. They replaced 1 sensor the first time, in between all of this the diesel pump blew up..... They replaced every fuel related part on the vehicle except for the tank. But the fill AdBlue light continued to come on even though it was full. They are now replacing another sensor and the fuel pump. They also say this is not a common problem......

I too have AudiA7 (approx. 8 months' old) and have had Adblue warning light. Added Adblue, drove approx. 1,000 miles and then light came up to say 500 miles to go then no RESTART! Limped back to UK, called out Audi and am still waiting to find out which of 3 parts (sensor, pump and tank or something in the exhaust) is the problem. Not good for a car that has only done 11,000 miles.
