    Default 407 coil pack.

    Hi All,
    Can anyone advise me if it is safe to drive with a failed coil pack? I was thinking of driving to work and back, just once (about 60km round trip), before replacing it.
    And what causes these things to fail so frequently? I recon I replace one of these about every 4 months.

    I'd not recommend it, the risk of cat damage is too high.

    Since it passed 200,000k I seem to be replacing a coil pack on my V6 407 every month or so too. I have to drive 45 to 60 kms to get a new one and replace it and I have had no dramas with anything else (so far). The trip to Brisbane and back next weekend will be a test.

    The Delphi brand coils have a better reputation than the originals & el cheap ones I have read.

    Thanks guys, I won't risk it. I think I'll buy 2 so I have a spare always on hand.

    Out of interest, assuming is it misfiring , what OBD error codes did you have ?

    Did the depollution faulty error come up ?

    Leaking oil from the camshafts tends to cause misfires and might be the cause.

    A few weeks ago I floored mine going up the Spit to overtake (well past the speed cameras I hope) which it did not like much and it ran rather badly for the rest of the day, limping home but fixed itself (except for the warning lights which stayed on)

    I had the engine light come up, depollution faulty come up plus a few error codes P 1335, P 1336 and P 1340 and I thought I had burnt a few valves in the heads.

    Cleaned it all up (rear coils were in oil), degreased it again and ran it up the coast on a 200 kms return trip.

    All errors cleared today (must be the start six times cycle) .

    The errors were misfire on 2 and 5. And depollution and engine management light. I know the camshafts leak. When I cleared the codes, the fault was gone. Perfect timing, considering I had just purchased 2 new coil packs. I think you might be onto something, mg407.

    and the codes you had ?

    eg the so called Peugeot OBD ones I found make no real sense

    P1335, Position Camshaft Unknown
    P1336 Crank/Cam sensor range/performance
    S2000PM1/2 - High misfire on several cylinders
    ME7.4.5. Combustion misfiring on unspecified cylinders.

    P1340 Camshaft position sensor B circuit Malfunction

    I don't see any codes. Only a description of the error. I'm using diagbox, but I struggle with it every time I use it. It's a frustrating piece of equipment.
