After done with Baily DV's, the third day of drivng, the engine check light on!! Don't know why, but when I was driving my tt, my turbo booted seems strengh

I took my TT to Porsche dealer, I saw they checked on my car...the car showed error code is " SECONDARY AIR SYSTEM" and they reset my computer, then no check engine light. Done!!

After that, I felt seems I lose power on my TT and the temperature goes little high(normal on 180, but now is kinda little over 180, can some professional porsche doctor help me what's going on with my TT...

 

I would check all the hoses for leaks.

 

The secondary code is from the top vacuum hose being off or from the solenoid. Check the hose on the top of the BOVs and the Y. It comes to a Y then rolls down to a control valve. It is off in one of the three locations. The light will only flip after the 20 minute cycle in the system.

 

Exactly the same problem I had. One of the small vacuum hoses on top of the DV came off.

 

I had a split DV hose and received that error code as well.

 

Porsche doctors, Yes....right...Problem is the small vacuum hoses . really appreciate ...

 

After test drive my TT, the boot only can top to 0.7, but there's no engine check light on, what can I do? do I need to drive to dealer for check?

 

If its a stock non-x-50 thats all you should get. If its chipped or an X-50 thats probably too low still. What was it boosting to before the DV job?

 

If you are chipped look at the connection on the y pipes. In a lot of installs that lip will get pintched and rolled and will cause a little leak under boost.

If no chip is present then the boost level is normal.
