s600 coil pack Help Please
Thanks for any help or any good advise.
If it's cylinders 1-6 or 7-12 that are misfiring then it's certainly the coil pack. If it's a mix of cylinders/random numbers then it could be either both coil packs or the voltage converter (box that sits in the middle of the valve covers)
Part Number:
A 275 150 06 80 (Passenger Side)
A 275 150 07 80 (Driver's Side)
These are MSRP $1250.00 at the dealer... or $1100 on eBay:

Working on a S65 engine and we try to get 1600 HP out of it.
Right, they make the parts in their basement.

brand new and you will have no problems. I wish I had read all the negative comments about them before I purchased mine. FYI I have had the BBB and FL consumer advocates after then, no response. everyone else beware!
Maybe you should take a minute and jump off your high horse and reread Oxygen's last post! He was just quoting the company YOU did business with not him! Nice job.
He has helped MANY here on this forum, and is a pioneer on modding them.
I understand it was a simple miss reading issue. But I would advise you my friend, to think twice before you jump here.
Take care and good luck
Misfires can be caused by a lot of things, not just coil packs (though they are common). Its worth trying to cross off all the other things first. Look for errors in all the other sensors; replace the fuel & air filters; could there be any vacuum leaks; are the spark plugs OK; water in the fuel; etc?
My DTC's were also showing mixture problems, and the long-term mixture adjustment was well out. I didn't think a coil pack would fix that, and since there's no MAF sensor, I looked at the pressure, temp and O2 sensors.
First I replaced the two control O2 sensors. Though the new ones seemed to perform better, with faster output response and steady control sensor outputs, the misfire remained.
Second I replaced the MAP sensor that's connected by a short tube to the RHS intake cooler. That made no difference whatsoever.
Then I bit the bullet and replaced the RHS coil pack (the LHS one had already been replaced with the new P/N type). Now I was able to use full throttle for the first time, but occassional misfires still persisted, often on light running.
The I realised like an idiot that the MAP sensor I replaced wasn't the one used for mixture control - that was the sensor that's screwed to the front of the intake manifold. So I replaced that, and all the misfires instantly disappeared. Unfortunately I forgot to tighten one of the intake hoses, and I had an air leak and loss of boost.
However, this showed I'd really had a mixture problem all along, which made me wonder whether I'd really had a bad coil pack after all, and what would it have been like if I had replaced the primary MAP first. Curiosity got the better of me, so in the name of scientific understanding and the greater good of the V12TT turbo nutters community, I refitted the old coil pack.
I took the opportunity to fix the intake leak, but unwittingly created another one, so while I had a car that behaved itself, there was still no Eutopia behind the wheel. Thinking that I may have been premature in buying the coil pack, I wondered if the old one was in fact serviceable, allowing me to sell the new one for a reasonable price.
Sadly not. The misfires returned on longer runs, seemingly when the engine was thoroughly warmed-up (much as it had always been). So tomorrow the new coil pack goes back in, hopefully to weave its magic with the new O2 & MAP sensors - and hopefully no more damned air leaks! Maybe this weekend I'll finally find out what a Eurocharged S600 can actually do.
If I have time I'll look at the subframe mountings to see if they're worn and causing some bump-wriggle. I'll take the front bumper off and see whether I can fit a large heat exchanger and upgrade the IC pump. Sound 8 is just TOO excited with his car to ignore. I'm also going to pull the old coil pack apart and have a play with it sometime; see if I can see or measure anything wrong.
Its all a bit of a labour of love, isn't it?
