Introduction to Audi Diesel AdBlue
Among the many brands using Diesel Fuel in Europe, Audi was one of the first to install a Diesel Engine in an executive car, such as the Audi A6. The Engine was reliable, and the driving experience was excellent. In spite of this, Emissions remained an issue.
Over a decade ago, Audi introduced AdBlue in the Exhaust Systems of certain Audi Engines to reduce harmful Emissions from Diesel vehicles. Audi AdBlue is a Diesel Exhaust Fluid (DEF) made from a solution of urea and deionized water. AdBlue is stored in a separate tank and is automatically injected into the Exhaust System as needed while driving. When injected into the Exhaust System, AdBlue helps to break down Nitrogen Oxide Emissions into harmless Nitrogen and water vapour.
AdBlue helps these Audi’s to meet emissions regulations, pass the annual MOT test and reduces the environmental impact of Diesel Engines.
Audi A6 Diesel AdBlue Case Study
One of our clients experienced increased emissions as a result of a problem with their AdBlue System in their 2016 Audi A6. As part of their visit to Cheltenham & Gloucester Autocentre, our client explained to our Audi expert technician the issue, which related to the Countdown Timer on the AdBlue System.
The Faults We Found
In order to resolve the client’s AdBlue issue in their Audi A6, our experienced Audi technician first verified the issue with a thorough inspection of the vehicle and found several clues that could assist in the repair process.
Despite refilling the AdBlue Fluid, the Countdown Timer and the AdBlue warning were still displayed on the Dashboard. As a result, our Audi technician suspected there might be a problem with the Engine Management System (EMS) and the Selective Catalytic Reduction (SCR).
The client told us that they had taken the car to an Audi dealer, who suggested a different component was causing the issue and performed a software update. Unfortunately, this repair was not successful.
Fortunately, the client found Cheltenham & Gloucester Autocentre after reading our customer reviews and blogs while searching for a local Audi specialist. They were confident that we were the right garage to resolve the AdBlue issue with the Audi A6 – and they were correct!
After years of dealing with AdBlue problems, our experienced Audi technician approached the A6 issue with confidence. It was clear to him that both the Engine Management System (EMS) and the Selective Catalytic Reduction (SCR) were responsible for the malfunction.
In order to provide a thorough resolution, our Audi specialist conducted a 15-step diagnostic evaluation. All Cheltenham & Gloucester Autocentre technicians follow this process to solve problems in an efficient and effective manner. We don’t need to rely on guesswork, and we never swap out unnecessary parts. However, we do provide a first-time fix and great service with excellent value.
The Diagnostic Procedure
As soon as the Audi A6 was in our care, our technician began our trusted 15-step diagnostic process to identify the root cause of the AdBlue issues.
A short test drive was conducted to observe any issues with the car. It is crucial to conduct test drives to help diagnose problems that may not be immediately obvious when the vehicle is stationary. Test driving a car allows our mechanics to experience firsthand how the car is behaving and to identify any issues that need to be addressed.
Our Audi specialist at Cheltenham & Gloucester Autocentre used the same Audi Manufacturer Technology as the dealers to scan the vehicle for any relevant fault codes. As expected, they discovered several errors relating to the SCR System that required deeper investigation.
Before examining the SCR System itself, our technician conducted live data checks for the incoming and outgoing signals of the Exhaust Gas. The incoming signal is the Exhaust Gas from the Engine, which contains pollutants such as Nitrogen Oxides. The outgoing signal is the treated Exhaust Gas that has been directed through the SCR System, which if in full working order, will remove the pollutants by converting them into harmless Nitrogen and water vapour.
Our Audi specialist’s attention was drawn to an irregularity in these signals, which prompted him to examine the repair history from the previous garage. Often, this simple step can help speed up the diagnostic process. However, in this case, there was no solution to be found.
Our technician moved on to check the AdBlue Fluid levels. They found the Fluid to be of good quality, meeting recommended standards. Many people try to save money by using low-quality AdBlue Fluid, but it can harm the vehicle’s Engine. Fortunately, this wasn’t the case for our client, as they had always used the recommended AdBlue for their Audi A6.
With the Fluid in good condition, the software functioning as it should, and the issue not being an obvious or common fault, our Audi specialist was faced with a puzzle to solve. They suspected that the problem may be hardware-related. As a result, they decided to investigate further.
After inspecting the AdBlue Pump, the source of the problem was revealed. Our technician found that the Pump was not producing enough pressure to deliver the AdBlue Fluid to the system effectively.
After identifying the problem, our technician began the repair process.
Repairing the Problem
Despite repeated testing, our Audi expert couldn’t get the required pressure out of the AdBlue Pump. Replacing the faulty component and installing a new one was the only solution.
Our Audi expert replaced the faulty AdBlue Pump, refilled the AdBlue Liquid, and checked the pressure levels. After scanning, no errors were detected, so the system was now functioning smoothly once again. The Audi was now ready for our client to collect.
In Summary
With their vast knowledge and experience, our Audi specialist tackled our client’s Audi A6 problem with determination and skill. Despite challenges, he trusted in his training and experience and remained confident they could find the root cause of this AdBlue issue.
