I wasn't happy as due to covid shortages they were missing from my recently purchased Leon FR, but I have finally found a solution to 'retrofit' dynamic style rear indicators at a relatively low cost that's plug and play with no cutting of any wires, etc at all.
Working with someone who sells plug in modules for other VAG cars, using factory wiring diagrams and genuine plugs he has been able to produce a set for the MK4.
He'll be able to produce some more if there's interest, I am not sure about forum rules for posting this sort of thing though?
I am trying to upload a
video showing the module fitted to the right hand side.
