Creating a big Turbo Audi TT Monster.... PT3

In this episode, DJ tackles the final steps of transforming his Audi TT into a high-performance machine. After passing the MOT with no advisories except a minor exhaust blow, DJ encounters some unexpected issues on the way back—warning lights and immediate boost cuts hinting at potential vacuum leaks or split hoses in the turbo system. Diagnosing the problem reveals an intermittent misfire on cylinder 2, prompting DJ to install a new boost gauge on the A-pillar to monitor PSI levels and pinpoint the cause of the pressure drops. The gauge installation process is detailed, with wires and vacuum hoses carefully routed through the firewall to connect with the fuel pressure regulator. Test drives show the car overboosting far beyond standard levels, suggesting possible faults with the recirculation valve or a sticking turbo actuator. DJ then upgrades the PCV system with a neatly installed catch can, addressing previous leaks and stabilizing engine idle. However, overboost issues persist, leading DJ to plan further modifications, including replacing the recirculation valve to fine-tune the car’s performance. The episode ends with DJ reflecting on the troubleshooting process and looking ahead to future enhancements for his turbocharged Audi TT monster. MOT Test and Initial Issues (00:04 - 01:48): The Audi TT passes the MOT with no advisories, but a slight exhaust blow is noted. On the way back, warning lights appear, and the car experiences boost cuts, likely due to a vacuum leak or split hose. Diagnosing Boost and Engine Issues (01:48 - 02:47): The car shows an intermittent misfire on cylinder 2 during high boost, suggesting potential boost leaks. Plans are made to install a boost gauge to monitor PSI levels. Boost Gauge Installation (02:47 - 09:21): The boost gauge is installed on the A-pillar, with electrical connections set up and the vacuum hose routed through the firewall to the engine bay. Adjustments are made to ensure proper fit and connection to the fuel pressure regulator. Testing and Overboost Diagnosis (09:56 - 18:31): During test drives, the car overboosts significantly beyond standard PSI levels, suggesting possible issues with the recirculation valve or turbo actuator. The current working theory is that the diverter valve is faulty. PCV System and Catch Can Installation (18:31 - 27:04): The catch can is installed neatly in the engine bay, replacing old, leaking PCV components. This improves engine idle stability, though overboost problems persist, leading to plans for further modifications and replacements of the recirculation valve.
