407 coil pack.

[tonch504]

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.

[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.
