This is the only class class action I have taken part in, and although it took several years from start to finish, I'm glad I participated. I believed what VW had done (cheating emissions!) was both wrong and indefensible. I had owned the car from new and following its emission modification it never ran smoothly again, despite repeated returns to the Audi main dealer. The form filling wasn't overly difficult and there was a need to occasionally confirm the details and ownership as still correct. Apart from this there was nothing else to do except read the updates from Slater and Gordon detailing the latest court hearings. Then finally a very pleasing update arrived, saying VW had conceded and agreed to pay compensation. About three weeks later a cheque arrived in the post and the sum I received was very close to what was anticipated.. Taking part in this was not worrying at any point and I definitely think it was the correct thing to do. Slater and Gordon did all of the work and kept me well informed about progress and likely outcomes.
