hi i know im not the only one with this problem and i have also seen people post asking how to fix this issue but no one posts what worked after they did it

i have an 2001 audi tt cupe 225 and once the car is warmed up and i bring the car to iddle (at stop light) my oil pressure light comes on and my coolant gauge peggs out to cold then once accelerate all returns to normal
also as time goes by it gets worse and worse.

if any one knows the the solution please send me a message or just post

 

I would guess either your ecu or gauge cluster is broken. Each are around the $900 range. Most likely only one is bad.
