Hey mate what was the part # of the Bosch coils? I think mine just packed it. One week into stage 2 and p1339. Been throwing cat cels every 200kms as well ... Might be related?

So I've actually got 4 cels:

P0353 - Ign Coil "C" Pri/Sec Circuit
B2AAA
P030 - Cyl3 misfire
P1339 - CrankPos/Engine Speed sensor cross connected

Understand these are probably all related. I'm looking at RCZ coils atm ... Bosch C9199, are these the right ones?

Excellent thanks mate!!

Looks like I might have a hard time getting them locally gonna be a couple of weeks without a car by the looks of it.

I decided to move the coils around and sure enough the misfire moves with them. Had a misfire on coil c to begin with moved the plugs and the cel came up on coil b

Funny the Bosch coils were cheaper than the ome Peugeot could by almost half. The plugs are a pita to source here, almost went for the stock plugs but found one place online that would ship them from a local Warehouse, all others came from Europe, 5 - 10 day shipping. Ordered a socket from bmw, everything should arrive by Thursday

So I pulled the plugs today after getting the misfire codes, to my surprise these are NGK ILZKBR7A-8G NGK Stock Code 5992 I thought OME were bosch coils... OMG check out cyl 2&3! This is after 15000 kms from new

Also, coils were rusted!! How the hell does that happen??

My bad, I thought stock plugs ere bosch. Apparently not. NGK Iridium came out of mine. The coils I pulled were bremmli.

New plugs and coils went in today. Misfire has cleared and the idle is so smooth now. Power delivery seems punchier. Codes are cleared and have not yet come back.

On to better times

No I don't think it was the etuners tune, I only had that on for about 1500kms before this happened, not enough time to foul the plugs like that. And if it was a tune issue, all four plugs would be fouled.

Coils were rusted on the outside, which means water has somehow got to them. The two worst coils were connected to the two fouled spark plugs, so those plugs have not been operating well for a while, thus the buildup.

No idea how this happens but certainly has nothing to do with the tune. This typically happens if you high pressure wash the engine, which I do not do. So either the dealer has been or perhaps the underbody wash from the auto car wash??

 

[crembz]

Etuners recommend fresh plugs before the tune and replacement every 20000kms. At stage 2 the life of plugs is less again.

The stock coils have been known to fail quickly once the plugs fail. The Bosch coils are meant to last longer and not fail completely if a plug dies.

In my case I don't think the plugs took the coils out. The rust on the coils on cylinder 2 & 3 mean water has got to the coils somehow. Water and coils = bag juju. If they're rusted on the outside they're almost certainly stuffed on the inside as well. This is evident by the fouling on the corresponding plugs.

If you're changing the coils may as well go the Bosch. If you're at stage one change the plugs to be safe, inspect the coils. I wouldn't change them unless your motor is running rough or there's evidence of physical damage.
