Where is air con filler valve on a meriva?

The air conditioning (AC) filler valve on a Vauxhall Meriva is typically located on the AC low-pressure line, which is usually connected to the compressor. To find it, look near the front of the engine bay, often near the radiator or compressor itself. The valve is usually a small, threaded port that may have a plastic cap. Always ensure the engine is off and the AC system is not under pressure before attempting to access it.
