Audi Q7 Not Starting – Caused by Faulty EDC17CP44 Engine ECU

The most common reason that your Q7 won’t start, and something that you may not have considered yet, is usually down to the malfunction of the Audi Q7 ECU. This ECU, known as a Bosch EDC17CP44, is a problematic module that, when it becomes faulty, will also illuminate the engine light and store multiple fault codes for injector circuits, most prominently P2146 - Fuel Injector Group A Supply Voltage Open Circuit.

These fault symptoms usually happen randomly, without warning, and often even begin as intermittent issues, but what is certain is that these faults will become permanent if not rectified early. Often you may be able to read fault codes via diagnostic equipment including, but not limited to, P2149 – Fuel Injector Group B Supply Voltage, P2146 – Fuel Injector Group A Supply Voltage Open Circuit, P0203 – Injector Circuit Open Cylinder 3 and P0202 – Injector Circuit Open Cylinder 2. However, eventually, you will likely find that communications to the engine ECU will no longer be possible, and the vehicle will fail to start.

Faulty Audi Q7 ECU storing fault P2146 amongst others? What’s next?

Typically, when you are confronted with an illuminated Audi Q7 engine light and the above issues, manufacturers will suggest that you purchase a brand-new engine ECU to resolve these problems.

However, new replacement ECU’s will require coding to the vehicle, costing extra time and money, and are often on back order. What’s more is that once you do get your hands on a replacement, you’ll find that it will fail later down the line. This is because the original manufacturer defects have not been engineered out at factory level and are still present in the ECU internal components and design. Top all that off with a short 1-year warranty and you’re asking for future trouble.
