Turbo Pressure Sensor - Wastegate problem 850 97

posted by  someone claiming to be Clyde Neal on  Mon Apr 2 15:35 CST 2001 [RELATED]

A year ago, the pressure sensor went out on my 97 T5. The turbo still worked, but before it could build any pressure, the wastegate released it. Therefore, there was no usable boost.

The dealer fixed it at a hefty price, and said it was a very rare problem. Now, it has happened again. What could be causing this? Any ideas?

Can I replace the part without removing the blower? I replaced the timing belt (70,000 miles)last month and it was a piece of cake. How about the turbo sensor, any suggestions would be appreciated.

Thanks for the help,

Clyde Neal

    Clyde,

    What sensor are you referring to? Where is it located?

      Jari,

      It's the "turbo pressure control" or the "turbo valve" I've seen it called by different names. It is located at the turbocharger. It is connected to one or more of the three color coded lines (red, yellow, white). My Haynes manual doesn't give it much mention.

      I just found my service invoice from last year and the unit was replaced on 4-21-00, and has a 12 month warranty!!! So, I'll go see them, again.

      Thanks,

      Clyde
