Just bought it, taking off when in a hurry mostly, a complete total dead spot/flat spot, that actually almost launches me and passenger through the screen, half a second in duration not much more, but I would like to know where to look, ie fuel filter etc. There are no fault codes recorded, and no warning lights or any other indications. There are no other acceleration probs at any other revs, the car will pull strongly right up to 100mph plus soo... not the worst prob, but do not want it to become worse either, any help much appreciated.
Also car has had full BMW service history ( JKC, Coleraine, Co. Derry, N. I.)
