In this 100% unsponsored video I share with you the process I used to diagnose and attempt to fix the engine issues with Project RS4, the cheapest Audi RS on the market when I bought it in August 2025.
It was cheap for a number of reasons but the main one was the EPC and EML warning lights which were illuminated and wouldn't clear due to an issue with the intake manifold flaps.
When this happens, owners take the car to a specialist who simply removes the flaps as they are told they are just for emissions (or similar) and this reduces the risk of the problem recurring.
As I am a hands-on owner I wanted to see exactly what the issue was and if there was a cheap fix for it, which would mean I didn't need to pay a specialist for any work and I could keep the car original, well that's a win-win in my book and money saved on this can go on the bodywork restoration, more on that next time.
