Rpm fluctuations
A4 b8, 3.0 tdi CCWA engine. It has 270k km.
The problem - when the car warms up to 90, everything is fine till you turn on the AC (sometimes if its too hot even without the AC) the cars rpm gauge stars going up and down for a bout 1-2mm. When you coast also. So when you don't give it a bit gas, the car SOMETIMES shuts down due to too low rpm. AND... sometimws when its warm, it can be fine UNTILL, i manually turn off the car and turn it ON again. The car will shut down every time without gas after 5 seconds. And when the car is cold, everything is perfectly fine. The car has no power loss, pulls like crazy. NO engine vibrations or anything. PERFECTLY FINE. It's really annoying sometimes cuz when you coast in neutral the car shuts down so smooth you dont even notice its off.
