SL55/63/65/R230 AMG: Just got SL65 V12 tuned ! but splattering :(

YOU DON'T READ - I recommended International Autohaus - THIS IS NOT ONLY MB DEALER.
Do you know why I recommended them ???
They BUILT the fastest C63 in Australia 9 Second car on 1/4 mile- and are EVOTECH-Software Dealer for Australia, 800-900 HP MB Turbo-Projects - they are laughing about your little problems with missfire.
You say SL65 is no rocket science - but for you it is!!!
Get this job done by a professional who has experience - and IMPORTANT : Direct access to your car - can work PHYSICALLY on your car!!! Not only over phone or E-Mailing and going back and forth - ahh my plugs are good, ahhh my coils are good - I will repair them by myself.
What a bull****...
The coil packs on my 2007 S600 originally were replaced at only 8k miles in 2009. The replacements at that time were still the original part number. My engine started throwing misfire codes a couple of weeks ago and it turned out to be a coil pack. I only have 33k miles. A new coil pack was installed on only 1 bank with the new part number. My SA advised me that the other bank will likely be going out in the next few months. That's just how it goes with those packs. My car runs the same coils and plugs as yours and isn't as stressed since it has less HP and is not driven hard. These coils are wear items, and yours just happened to wear very well. No need to blame EC for this, because your coils were going to go very soon any way. I hope what others have said about the new coils being more reliable and longer lasting than the originals is true.
Regarding you being upset about the resale value of your original coils: Those were basically useless any way. The coils that you see being sold on eBay for $500-800 are rebuilds, not old worn originals. Your old coils will likely have some value to people who rebuild and resell them...so you should be able to get something for them.
Good luck....and I hope you get it all worked out.

ABC tandem pumps and Arnott struts look more than reasonable as well.
Thanks, Nick

There seems to be a perverse pride in the forums about spending lots on maintenance and repairs. If the repairs cost more than the car, so much the better.
My objective is to spend as little as possible, while still doing the job right. I've had to fix just about everything on mine, and only the coil pack cost more than 100 or 200 or so.
Never again. It will be either RockAuto, MotorKing, or used coil packs for me in future.
Nick
Edit: Of course, the area where I haven't been so successful has been in spending as little TIME working on my car as possible. Over three years, I certainly spent more time under it than driving it. Is that as bad as spending more money on maintenance than on the car itself?

It takes your mind off all the banal worries you have, and makes excitement
looking to fix your car, how cheap can I get it, will it go better when fixed,
and when all is fixed it's back to mundane worries like how do I pay the mortgage..

But as I have the coils out of the car and opened I will replace all transistors, By far cheapest best option if this works. If it does work I will definitely be doing a rebuild as soon as the other side fails, But I will replace all coil cassettes this time which is $500USD including transistors for whole kit to rebuild every coil and all transistors.
The most satisfying thing about doing this would be saving a heap of money and accomplishing it without any MB specialists playing God with my car repairs. It also gives me confidence to keep the car , in the event if I face this same issue again down the track at least I know I could fix it in a day, and not have to wait months on end for coil packs to come the US.
Many people I speak to about these cars immediately say "there a good car , but coil packs and ABC", if this idea can be resolved , it will change the perception of how people view the car , ultimately a quick and economical fix will do this as soon as people adopt it. I hope I dont have the ABC problems so as a precaution, flushed all old dirty oil and put new mineral hydraulic fluid in
so far so good

I need a good tuner to send me a file, anyone have any suggestions?

I have no direct experience with them, but know some MBW members who are happy with them. One member has an ECU/TCU tune from Speedriven for his SL65 and loves it.
I don't understand how so many can enjoy the tune but you think its problematic. No affiliation or special tuning here, and my car runs great. The tune's safety was verified on a dyno and has recently proven itself on the track with additional mods. The risk for greater maintenance and wear and tear exists regardless of the tuner. Extra power is not drive train friendly. Good luck with who ever you choose.
