The WUR’s used in CIS have this type of plug on them. The spring is used to secure and lock plug in place. The plug will not come off easily without applying sufficient side to side pulling motion (wiggle) to unlock this spring.

Look very closely on the locking tabs on the sides of the plug. For installation, outer angle of the tabs is approximately 45° and the inner tabs have greater than 45° slope. So you would need a much greater effort to remove or pull out the plug compared to installation.

If is mandatory to use a pick for removal, how on earth would you be able to remove the AFS switch plug, CSV plug, or FV plug with the engine in situ? I will give you several hours to remove this spring with engine in situ. The key to removing this type of plug is to exert a side to side pull (wiggling) to get the locking spring slide over the the locking tabs. Go over the garage and practice removing it. I’ve been working with Bosch WUR’s for many years now and I could not recall exactly how many times I’ve done this maybe several hundreds or thousand times (?).

People been doing a lot of reading and that is good. But they lack hands on experience. This a very good example how people think and understand how CIS works. And this is just the “spring”. Wait till it comes to actually doing the CSV and fuel injectors tests and evaluation.
