Now I ve sent the car to the service to get the check engine light reading and they say I have SCR (I think) pressure pump low. They tell me that the pump and tank adblue and even a new control unit is needed and they cost over 1500€ ! I ve picked the car back up and topped off the adblue. The check engine light stayed on but the low adblue
That'd probably do it. A8 / S8 (D2 Platform) Discussion - Check level / top off transmission fluid - I've read a considerable amount regarding the pros/cons of flushing the transmission, and I'm not sure I want to do a full flush given the potential risks. However, I am interested in checking the level of the fluid and adding more if I have a 2009 Audi Q7 TDI, early 2009 manufacture date. ECM was last updated in 2014. I'm on the latest version of VCDS and had a problem with the AdBlue countdown stubbornly refusing to reset with both AdBlue tanks full. *I'm certain both tanks are full. It was not yet empty when I refilled, and it took well over 5 gallons (over 20 liters).
AdBlue Explained. One of the latest ways to make a car more efficient is through selective catalyst reduction. Also known as SCR, this treatment system converts dangerous pollutant chemicals like Nitric Oxide in Nitrogen and water which are both far less harmful. This can be achieved by creating a compound made of CO2 and ammonia.
Also, check the acid level of battery only if the level can be seen through the housing and fill if necessary (except Audi Q5 hybrid) Charging socket: Check for damage and make sure the socket is dry (Audi A3 e-tron only) Crash active headrest - Check function (Audi A8 only) Cooling system - Check coolant level and add coolant if necessary
AdBlue® Fluid - Fill completely with fresh fluid and adapt learned values for AdBlue tank under guided fault finding after filling fluid (All TDI models) Brake system - Check for damage and leaks, thickness of pads, and brake fluid level. Check that the vent caps are mounted on calipers and check the condition of the brake hoses Received 101 Likes on 93 Posts. AdBlue leak at wheel well. AdBlue filled 200 miles ago. Drove the Q7 about 200 miles over 2 days. Parked outside overnight with temps in the teens. Woke up to find a an 14 inch diameter puddle of crusty def on the ground behind the left rear wheel.
