pharmoun Posted May 25 Share Posted May 25 After a year of ownership, I noticed a decrease in power and the appearance of the Engine Check Light in the last four to five months. I am able to clear the code P0299 (Low boost) using a diagnostic checker. However, it reappears a little distance down the road. No leaks were found when I tested all of the hoover lines with the smoke tester. Everything is Okay with the intercooler and both hoses. The EGR Actuator, however, remains inactive throughout beginning and throttling. The actuator is free to operate while using a vacuum hand pump. The brake servo would undoubtedly provide symptoms if the vacuum in the system wasn't present, but those brakes are sharp and strong. Ideas are what I'm seeking. Is anyone able to lend any assistance? Quote Link to comment Share on other sites More sharing options...
DMGRS Posted May 25 Share Posted May 25 The P0299 code often indicates a problem with the turbo or a boost leak. The moment my turbo died, I understood. Quote Link to comment Share on other sites More sharing options...
Ken_Lion Posted May 25 Share Posted May 25 In my understanding, they are standard on the lower intercooler hose. Have you made sure both times? Prior to this, I had one that only let smoke out during the smoke test and only leaked while I was under boost. Quote Link to comment Share on other sites More sharing options...

pharmoun Posted May 25 Author Share Posted May 25 I appreciate you providing the data. After removing the Red and Black ones, I looked inside for damage or cracks and made sure the O-rings were in good shape. Both of them were attractive. The smoke test was performed after the reinstallation, with the red hose being connected to the engine before the turbo was mounted. The intercooler and black hose were checked afterwards.

Psychil Posted May 25 Share Posted May 25 Keep an eye on the vacuum transducers. Failing to hold a hoover is a regular occurrence for them. Quote Link to comment Share on other sites More sharing options...

pharmoun Posted May 25 Author Share Posted May 25 Your name slipped my mind. Following your suggestion, I gathered further information and discovered a comparable problem with an A Series. Yesterday, I received the Vacuum Pressure Transducer that I bought from GSF. After clearing all the errors and replacing the transducer, I was able to get my car back today. Works Great! I appreciate you pointing me in the correct way. Quote Link to comment Share on other sites More sharing options...
