Key to this tale will be if it is marked on the insurance register as stolen recovered, IF it is then you need to pursue your insurance for diminuation of value as that alone will make it almost impossible to trade in (to a VW dealer) and hard to sell on privately and will lead to prob 20% less value than an equivalent car. This will be down to your insurance company as to whether the record it or not, so a conversation needs to be had with them recorded = claim for 20% of value as loss of value due to recording as stolen recovered.
Plus I would want to understand that "major incident" IF it involved a high speed car chase then I wouldn't want the car back due to potential future engine problems, get the garage to run a diagnosis on the ECU and look for number of rev limiter bounces / cut outs, this will tell you if the thrashed the engine to within a inch of its life. No other way than an interrogtaion of the ECU, your VW dealer will be able to do this, or someone with VCDS. HTH's John
