TT Oil Pressure Gauge

Recommended Posts

Just changed from a 2003 C2 into a new 2004 TT and the oil pressure gauge on the TT behaves quite differently. Instead of a smooth, one movement gradual drop and rise when rpm/throttle is opened or reduced, whenever the throttle is gently opened or reduced between 2000 and 3000 rpm the needle first sharply swings down (for approx. 1 bar distance) and within a couple of seconds returns back where the real pressure is and then continues to move either up or down "properly". The pressure reading is correct, it just looks as if there is a momentary "electrical" glitch whenever the throttle percentage is changed. Could the damping of the needle be somewhat incorrect or is it somethinh turbo engines do as a matter of course? Does the fact the it is the oil pressure that governs the Variocam to some extent a fact to be taken into account?

Any feedback appreciated as I have never seen an electronic oil pressure gauge do this.

My '03 does exactly the same thing. I can only conclude that it is an electrical glitch as the oil pressure cannot drop as fast as the gauge indicates. If I drive at 2000 rpm, and blip the throttle suddenly, the needle will drop 1 bar and pick right up. This all happens in 2 seconds or less.

Thanks for your feedback. The fact there is 2 of us means it is much less of a conicidence. I am not worried or paranoid since readings are proper and accurate once the indication comes back where it should be. I will try to find out through my contacts at the factory what makes it do what it does.

Thanks again,
