Just got a 2017 T6 104hp, 10k on the clock. A week before, I saw and drove the van everything seemed silky and the engine ran with a light bumble, you wouldn’t notice it running. I decided to get it. I picked it up late evening drove it home at night a bit nervous as it was my first t6, The next day I took it to the garage for an authenticity check, I noticed a noisy squeaky start, put it down to the cold morning. Drove it, it seemed a bit, not so perky. Got home round trip of 30miles, got out of the cabin and noticed that the engine was much louder then a week before and it had also developed a knocking sound. My question, is there a way to tell if the engine had been removed, a better conditioned motor dropped in, for the sale and then the original motor put back in, a week later. Any obvious signs to look for thanks in advance.
