"made by Bosch apparently",If it is a genuine part it will have the Bosch name and logo stamped on the top together with a part number.Genuine coil packs on these rarely give problems.Also what make spark plugs are used and check the electrical connector to the coil pack to check the pins are clean and tight.hth

Two things I know of which can contribute to premature coil pack failure are excessive spark plug gaps and possibly HT leads breaking down, as these cause a higher than normal build up of voltage at the delivery point of the coil pak.

Failed coil pack. Had that with my Ford Fiesta Black Special Edition. I got to a garage in 1st and 2nd gear with all the dashboard lights flashing on and off, and constant back-fires. New coil pack, new spark plug leads, new spark plugs. All fitted and working fine. One month later car started having same symptoms, pulling back on power. Took it back to the garage and replaced coil pack for free under warranty. They said it's the last time they do this. Technician asked me if I opened up the bonnet and jet washed the car. I couldn't believe what I was hearing. I said no, and never do that sort of thing. He found water on the engine, and had it down I drove over a large puddle and water somehow got over the top of engine. Lucky lucky for me, at a party I got talking with a Senior Ford manager. Well, it turns out the windscreen washers were faulty. For my year model, Ford made 1000's of faulty windscreen washers. They leak at the back under the hood side. Seals are faulty. Get your windscreen washers replaced asap. If I hadn't spent under £20-00 to replace them, the coil pack would keep shorting out, and damaged.
