``Inlet manifold swirl flap of 530d prone to breaking off and being ingested by the engine, wrecking it. www.pmwltd.co.uk has a solution for this, which is a billet aluminium blanking plate that is substituted for the swirl flap. Well worth doing because it could save the cost of a new engine or having to scrap the car. Only cars from 2001 to 2004 are affected. So early E39 cars (from 1996 to 2000) are not affected. Some 2000 models may be affected, but very few. If you're not sure you can locate the air intake manifold (black plastic on the passenger side of the engine bay) and your hand fits underneath. If you feel a metal rod running the length of it underneath this manifold, then you do have swirl flaps. No rod, no swirl flaps, nothing to worry about. ``
