VW Touareg air suspension does not rise after compressor repair
Perhaps the compressor was badly repaired. It is necessary to check whether it injects the necessary pressure. Also need to check the correctness of the connections. For example, they could simply forgot to connect the pneumoline, going from the cylinder to the swap wheels. When dismantling the compressor, they disconnect it. After installing the compressor in place, they could forget to connect them and all the air comes out of the system.
