Wonder if someone could help me with a problem my car has developed. Its a 2001 A3 1.8T, the oil temperature normally sits at 90 degrees. I noticed yesterday that when i start te engine the guage moves slightly, up to 60 - 62 degrees but no further. This morning it did the same but at one point moved up to 70 and then straight back down to 60. Somebody has said this could be low oil level, the car is booked in for an oil and filter change tomorrow. Is that the case or is it likely to be something else? Thanks for any help!
