Hi, My car is a 2006 Astra H 1.8SRi VVT
As the title suggests, i believe i have a leak on my Air-Con System.
After investigating i found that when pressing the AC button, i could not hear a tap nor could i see a dip in engine revs which would signal that the air-con pump has engaged.
Then whilst looking around the engine bay, i came across a green substance around one of the air-con pipes [ picture below ]
This substance was found just under the air filter box on the drivers side of the vehicle, and after reading various threads, i believe this is a visible aid to help find leaks?????
Hopefully all i will have to do in replace a seal at the joint and re-gas, but can someone just confirm this is all i have to do, or should i replace/investigate more?????
