Notes
In the opening segment the presenter recaps the situation with the wrecked Audi S3 and sets the goal to rebuild it for a friend. He notes that a misfire appeared when trying to start the engine in the previous video, signaling a mechanical hurdle to resolve before moving forward with cosmetic work. The plan for this episode includes diagnosing the engine issue, refitting the front end, and mounting two inner wing sections sourced directly from Audi due to damage. Throughout, the process blends substantive repairs with cost-saving choices, such as replacing damaged throttle body components and coolant housings with affordable second-hand or OEM-replacement parts. The video also documents the reassembly of the front end, the radiator pack, wiring, and battery system, followed by a first attempt to start the engine after these changes. The host discusses the structural status of the car as a possible category S repair, highlighting the aluminum inner wing and the practical decision to replace it rather than attempt a jig-based fix. He emphasizes careful sealing to match OEM finishes and shares early painting steps, including a base coat, primer, and a matte lacquer attempt to blend the body color across the chassis. The narrative then shifts back to the engine bay where the throttle body, new coolant hoses, and a few critical housings are installed, with the objective of eliminating leaks and achieving a clean, reliable start. The presenter demonstrates a pragmatic approach to reassembly, ensuring the cooling system, battery, ECU housing, and fuse box are correctly reconnected before the first engine run in this session. The video conveys a balance between mechanical feasibility and budget-conscious sourcing, aiming to keep the rebuild progressing while managing expectations around fit and finish of aftermarket components. The episode closes with the engine starting under cautious optimism, followed by a partial success in the form of a smoother idle and improved sound after a post-service check, while still acknowledging lingering misfire issues and a coolant leak that may require front-end disassembly again. Viewers are reminded of upcoming work like finishing body panel alignment and evaluating the front bumper setup, with a call to subscribe for the next installment.

Questions answered
- What caused the initial engine misfire in this build episode?
- The video indicates a misfire was present after the prior attempt to start the engine, with potential causes discussed including injector coding, spark plugs, and coil packs. The episode proceeds with servicing the engine, replacing spark plugs, and rechecking fuel and ignition components to determine if the misfire can be resolved without further disassembly.
- Why did the builder choose an aftermarket RS3 style bumper instead of an original RS3 bumper?
- The builder opted for an aftermarket RS3 style bumper because genuine RS3 front-end parts are very expensive and difficult to source, especially for a saloon. The aftermarket bumper was chosen as a more affordable option that could still align with the existing wings, with the caveat that fitment and cosmetic details like badges and grille would affect the final look.
