On my 04 SL600 when i got limp mode, my MBZ tech guy also said there was a new MBZ tech bulletin of how to fix the coil wiring harness, which has problems too according to MBZ. In my case on my SL600 RENNtech ECU, he fixed that harness according to the MBZ bulletin, but a few months later needed a new coil anyway.

The old coils were absolute garbage. When you get a tune, you end up changing ignition timing, and with the original coil packs and voltage transformer being terrible even on stock timing, it's no wonder that a more aggressive ignition would cause them to short. I'd just do everything - both coil packs and the transformer. The updated MB models have a very small failure rate.

sl65monsta- your coil packs were already on their way out. The tune didn't make them go bad, they just accelerated them going out faster by putting a minor amount of additional strain on them. You were going to have to replace them in the next year anyhow even if you didn't get the tune.
What you're doing here is the same as someone who added a tune or other power adder to their car being mad that it made their transmission go out. It wasn't the tune that made the transmission go out, it just exposed a ticking time bomb that was about to go off soon anyhow.
At the prices you are talking for coil packs you need to see if some place will ship international like autozone, who has a lifetime warranty on the part. There is a sponsor on the board that give a lifetime warranty ON ALL PARTS including wear parts like brake pads. I bet they'd ship them to you and save you a boatload of money on the coils

I kind of agree with EC, should have done the research more thoroughly.......I have read a lot about EC over the years.........and they're mostly good reviews

I remember being told that when it comes up as a misfire, first thing is to replace the plugs at fault. If it is still a misfire, then the coil pack. If the problem persists then the ignition control module. I don't remember hearing of a way that you can clearly pin point coil from control module. I had a warranty at the time and it turned into a bunch of down time back and forth when the shop anticipated the second one to fail.
If/when my coils are to fail again, I would replace plugs and both coils all at once. I personally would never buy used coils or spend the money on a refurbished kit. It could be a huge waste of time. What you save in the part will double in time and/or labor if you have to remove and replace. Also, who's to blame if it doesn't work if you are doing the refurbishing?
I would buy two new coils, the 24 plugs, and find an independent Mercedes repair shop to install. If that doesn't fix the misfire problem, then you will probably need the ignition control module.

If your plugs have more than 40K on them you are asking for trouble. They will potentially weld themselves to the block and then you are f'd. Mine were changed at 38K and were horrific looking.

plugs were changed a week ago, less then 150kms on them

so let me get this straight, eurocharged is claiming ignorance on coil packs failing after installing their tune? That doesnt sound right as im sure they know this is a common occurence. Why didnt you guys (eurocharged) disclose this as the customer asked if their were any shortcomings to intalling a tune from you guys?
Kind of messed up I would be pissed.

plugs dont weld themselves to the block and by block im sure you meant heads which are aluminum on the m275 and the plugs have metal threaded shells.

This entire thread is silly. You mod your car, you take risks. Yes, coil packs are weak. Yes, the tune probably made it worse.
Yes, you should have done the most basic Google search to learn this.
You took the risk.
I once had a supercharger added to my C5 Corvette, with a tune. Went too lean with the mechanic on the first drive and blew the engine.
Ended up costing me $20k. Did I complain? Nope.
I knew the risks. I'd done my homework.
Which is why I LOVE the Eurocharge tune on my SL65 AND E55. Am I risking needing coil packs?
Yep.

I bet you didnt even dyno your car to test it under load and adjust timing and fuel. If you didnt i wouldnt go around bragging about spending 20k on a motor lol. Since when do ls1s cost 20k anyways

"I cranked up my hp and something broke."
Welcome to making cars faster.
That said, coil packs go bad. Those particular units are known to be weaker than their newer revisions.
Id say be thankful you have so many people with experience and expertise willing to help you pinpoint the issue rather than spending hours of shop time diagnosing.
If you had spent a little more time listening to the wisdom from said forum posts before making the upgrades, perhaps you would have found the proper maintenance items might be higher priority than more power?
5 years ago when I got my Lightning, the first thing i did was port the blower and turn up the boost. It was a little faster and i never questioned it. A few years later i wanted more power so i got a twin screw blower and all the fuel mods. Well, turns out, i didnt gain anything. Weird... so it took me almost a year to find out my IC pump worked while sitting during inspection, but failed under load... i had iats through the roof! So when i finally fixed it, my new fuel regulator was worn and wouldnt seat properly because of all the fluttering it endured when the truck went in and out of limp mode at high rpm with high charge temps. Took me 4 years to finally get it running right, and a lot of shop diagnostic time after i finally admitted it was beyond my understanding to figure out the issue.
So with these higher ticket amg motors, i am doing my best to make sure everything is working properly before i turn up the power.
Best of luck taking care of the small stuff so you can enjoy your bigger power numbers and the true potential of your motor!

So the mechanic tuned your vette for the blower or you got a mailorder tune that was too lean for the mods you told them you had? Hope you werent careless enough to get a mailorder tune on a supposed 20k motor. Either way there has to be accountability for blowing your motor or you just like getting screwed. I pay a tuner everytime I mod my motor on my mustang entrusting their expertise that something so simple as a lean condition which would be caught on a dyno does not occur.

They also knew this was a common failure with tuning but failed to inform me, so liability is on them. If they had told me or there customers they would be up for new coils , IGN modules and possibility of frying the ECU I'm sure I would have not got the tune and many others would have not, so this puts them out of business. So is what I am saying wrong here ? no ! its the reality of life that people have a self interest , but I dont make a profit by hurting other people.
how exactly have you contributed to this ?

Yes. Yes. I didn't say it correctly. Weld wasn't the right word but they can get stuck in there and my tech said in layman's terms they are welded......

Hi,
I gave you good advice in the other thread - get a professional diagnosis by Autohaus Zetland, they will help you.
From my experience:
If everything (plugs, coils, IGN-Module etc.) were o.k. BEFORE the tune, a professional tune makes NO problems. Same on my car. No Problems (I have no Eurocharged Tune).
I am pretty sure there was something wrong before with your car - even if you did not noticed it.
This is the reason you always go BEFORE AND AFTER on the Dyno.
If the Eurocharged Tune would be the problem, others (like Racehorse with EC-Tune) would not run 1 whole mile races full throttle with no problems. This is real stress for the car.
Good Luck!
