Hello lovely T6 enthusiasts. I’m in Glos (GL10) and may need some diagnostic help. My AdBlue system has had a poo. Yes, I can pay £275 to get it mapped out, but would like to see if it’s repairable first. Just wondering if anyone is close to me with VCDS so we can see some sensor info and maybe try resetting the sensors etc. toodle pip. Howard
Hi
If your AdBlue warning light comes on even after you've topped up the tank with the correct amount of AdBlue, and you see a message saying you can drive only another 500 miles (or a different remaining distance), here's a method that has worked for me several times.
Accelerate until the engine is running at around 2,000 RPM. Choose a straight, level road with no bends, hills, or downhill sections. Maintain exactly 2,000 RPM for 6–7 seconds (the RPM must remain constant the entire time—this is very important!).
After that, press the accelerator pedal as quickly as you can all the way to the floor and keep accelerating for another 6–7 seconds (the vehicle's speed will continue to increase). Then quickly release the accelerator pedal.
If everything is done correctly, the AdBlue warning light should go out and everything should return to normal.
If the warning light doesn't go out on the first attempt, repeat the procedure until it does. The whole process must be carried out very precisely.
I hope this method helps others just as it has helped me several times. Good luck!
