I wasn't blaming anyone. One thing if you already replaced the coil packs once and they failed again after the tune you might want to look at the ignition control module. That could also fail and cause your symptoms.

SL65MONSTA

From reading posts, a mercedes specialist has said they have never once had a failed IGN module, usually its the coil packs. This should have been told to me by the tuner prior to uploading a file that will blow my coil packs, these are worth good money and can also fetch good money used. Instead the tuner does not tell the customer , because chances are 99% of customers will not want to go down the route of replacing perfectly fine working coil packs for a tune file. But now I have to replace them weather I want the tune or not, this is "sneaky" on the tuners behalf. Its not like he never knew, if he didnt then there wouldn't be three other members who've also posted this exact same issue on the exact same car from the exact same tuner "EUROCHARGED" if this was Australia , he would get sued! or worse ! Then he emails me saying he's gonna try to help , if he wants to help "send me over two new coil packs , that you failed to tell me will get destroyed from your tune!" lets see if he really does want to help ! Im sure he will come up with something else . I wasn't attacking you "Aeroman" its just that you kind of said the coil packs are not the tuners fault. I say it is, they have a duty of care to there customers to tell them "by the way you might need to spend $3000 on new coils for this tune to be compatible, oh and if you dont expect your car to blow your OEM coilpacks , and be of the road for awhile, whilst you drive home in limp mode!!!"

Listen you are really going off when it's in no way the TUNERS issue, especially if its a box tune! Your coil packs likely where performing ok before the tune, but that doesn't mean they were functioning at a 100%. Part of the tuning is done with the ignition, and when your asking more out of them they fail. It happens time and time again on aged coils and owners who put a tune on them. Hearing the age and mileage of your car I'm surprised your coil packs have made it that long "assuming there original" The coil packs more commonly go out on the m275's "v12" engines then spark plugs, and that's not an exaggeration.

You can look at this 2 ways. Put your head in the sand and blame the tuner, get the tune removed, still have the issues with the coils and ultimately replace them anyways. Or second, realize the early ones had a very high failure rate and were already on there way out. Replace them and find out just how much of a beast your 65 is going to be with the Eurocharged tune. It doesn't seem right for you to blame a company and Jerry for you issues when its a part failure not software. It's like having a transmission that's on its way out, tuning it adding tons of torque/hp, and then blaming the tuner for your transmission slipping and wanting a replacement.

Take a deep breath and a few steps back, either way you need new coils, replace them and have a true beast on your hands!

I will agree with Forced here on this one. Once my coil packs and spark plugs were changed out the car came alive.

RaceHorse

I agree with the two above. You should have been here seeking info before hand if this was such a concern. If the cost of the coils would be a reason not to get a tune then a SL65 is not the car for you. You will appreciate the car 10x more once you are back up and running properly with the coils. You will be beating even more cars than you have in the last year.

SL65MONSTA

You guys all might know Jerry and be mates, but that is in no way a reason to back up something that was not told to a customer. I dont fall for peoples crap and this is exactly what he's done, when I first told him , he added "lol" into his reply! Maybe your not seeing exactly what I am, you cant say my "coils are on the way out" the car was performing at least twice as better then it is now, the coils were fine, as soon as the tune was applied they blew. I am also not the only person on this forum who had this issue with the same tune and same tuner. You are burying your head in the sand to not have a bit of a spine and nuts to stand up to the truth. I have no choice now but to get coils so regardless this is not going to solve anything, but dont sugar coat exactly whats happened with this tuner to my car here !

Maybe I'm in the wrong site

1ForcedBenz

You absolutely are on the wrong site if you believe that a well known, common, and documented issue is going to get you sympathy or compensation. It doesn't matter who's tune you would have gotten as the end result of your coils failing would have been the same with any of the tuners.

What exactly are you seeking to have done at this point? It would be a completely different story if you came on here and said something to the effect of "my motor blew first drive after tune"

Your coils sadly are a maintenance item on these engines period. So hearing you try and hold someone responsible for a vehicle which A. You either don't understand or B. Are not wanting to maintain is a different story, I'll leave it at that.

SL65MONSTA

the coils should have been done first and these ones sold on to someone who has not got a tuned car and could of used them. They still sell on eBay $750 each, if that does not tell you the tuner could of prevented this all from happening, I'm done on this site yes! Eurocharged "Jerry" has tuned many of the v12's and knew this is a issue as many other members also are in the same situation as I am now, so he had the knowledge to foretell me before this, and before I purchased the tune, and when I had initially asked him would it affect or damage anything, and would I need to do any upgrades! his reply was "no, perfectly fine" "it will not damage your car", "no upgrades needed". Now your all sitting here saying "upgrades needed, essential" anyway go kiss peoples butts maybe he might give you a free tune, and help you blow your coils.

BlownV8

I don't know Jerry at all so don't take that where I'm coming from but trying to Blame Eurocharged for your coil pack issue is like trying to blame them for faster wear on your tires or for an improperly sized intercooler, heat exchanger, and exhaust that is too small, ETC, ETC. There is now way of knowing the condition of your coil packs when he sold you the tune.

Like another member said, if you blew your engine or if you had some catastrophic failure because of a bad tune, it would be different. You can't blame the tuner for a problem that the factory created. Odds are the coil packs would have failed with your stock ECU tune but there is no doubt that the ECU tune puts more stress on the coil packs due to the repeated failures of the old coil packs after most ECU tunes.

aeroman

If you had done your research before installing the tune you would have known. Taking any dealer at their word for something like this is a foolish game. Always find out what the community says not what they guy selling you something says.

SL65MONSTA

It is the tuners fault "Eurgocharged" for not telling me to change my coils, or remove them prior to tune, they are now useless to anyone, also my cars down time will be at least a month! Its also his fault because I specifically asked the question to him "will this tune affect anything?" or "do i need to do any upgrades?" his reply to this was , "no perfectly fine". Maybe because if he said to me look this tune will render your coil packs useless, and you will need to spend $4k on a new set of coil packs to Australia to run this tune. I would of almost definetely and maybe 90% of people would have not gone with the tune! do you see where I see this coming from ? He knew this, but withheld it! Moreover he was specifically asked about this, and lied, or witheld or forgot! buying a tune is not just about the actual software, its about the know how and knowledge base. They been doing v12s for years on end, there is no possible other explanation for not disclosing this. Guess who needs to cough it up? the customer. Please all of you try to understand where I am coming from

aeroman

Nobody knows for sure if anything will fail. But I agree he should have mentioned what could happen......

layzie12g

Well lets hope your bank account is also a MONSTA. Do not mod your car if you do not want to pay to play. I love when people MAKE THE DECISION to modify THEIR cars and then roll on ground kicking and screaming when THEY have to pay to fix issues that occur when modifying THEIR car.

V12= Coilpack replacement

End of story.

aeroman

any AMG is the wrong car to have if you cannot stand paying to play or have a warranty.

AMG = ALL MONEY GONE

euphoriaDSM

Not the tuners fault at all, this would have happened with any other company. The old coils need to be replaced. If you have any mechanical know how and tools go buy the parts at advance/autozone, they will come with a lifetime warranty, and change them and the plugs out in about 2 hours. The car will then run fine and pull insane hard. Again this isn't the tuners fault nor yours. Those original coils were made funky and revised and the new ones have no issue like this.

mcguirja

I actually think Monsta is raising a good point and highlights what I would have expected from an expert in this field, dealing with this everyday. (I may not have quite approached it the way he has but...)

Yes, I agree we should all do our own due diligence but if the questions were asked as Monsta describes it wouldn't have been hard for Eurocharged to have highlighted this issue rather than what (from a one sided perspective) appears to have been glossed over. The OP is simply highlighting pre tune he had options, post tune he doesn't. He could have replaced the coil packs pre tune, recouped a bit of money from them and all would have been happy. An unreasonable ask, I don't think so, I personally would have expected more given the same circumstances.

SL65MONSTA

The questions were asked to the tuner, he said clear and plainly nothing needs to be upgraded , it will not affect your motor. I am asking a specialist in the field, as I know modying any car usually requires other upgrades, but this is his tune not mine, he knows what it asks out of the car to run properly, he failed to be honest withholding this information and as a result it has now cost me a lot of money. Many tuners will be upfront and tell you what your getting yourself into, he didnt this is my whole point! oh and frying my coils because of his tune was his fault as I would of ordered coils and kept car factory until they arrived, but now my cars of the road and Mercedes Australia is asking $5195.50 per coil pack x2 . This is not what it costs for an extra 50hp buddy!!

read my reply above

someone with a brain and ***** to understand and say it for what it really is, I like honesty and respect people who are upfront. Not just looking for there own interests! now hopefully someone else will find this thread and not end up blowing there coils because "Eurocharged" refuses to tell there customers about this prior to sending files.

SL65MONSTA

it could be the IGN module, however replacing it with the exact same part number , wouldn't the tune still blow the replaced one ? or is there a newer updated module that can handle the tune ? it very well might not be the coil packs, its very unlikely they both blew at the exact same time?

aeroman

I think you will find only one is bad

SL65MONSTA

Sorry i think you misunderstood my previous post. What I meant was it is unlikely that both coil packs would go both at once, is there a way to test the IGN module compared to the coils? and is there an updated IGN part number , it just doesnt make sense replacing the voltage regulator with the exact same one that the tune blew ?

aeroman

The coils have been updated I don't believe the igh has. The tune didn't blow anything. It took tired old parts and stressed them to failure.

Just be glad your tuner is offering to help.

SL65MONSTA

From reading a post on here if both sides come up with misfire codes and the P0300 code its usually the IGN? or it could be both coil packs are blown. How does one tell? and if it is the IGN , wouldn't replacing it just blow it again anyway? I read on that same post that the dealer replaced both coil packs and there was still misfires until they replaced the IGN, which means that the previous coils were probably fine and just wasted money on replacing something that didnt need to be replaced?

i just dont wanna buy a IGN or coil packs if there not needed

sgaar

How do you know that the coils are 'blown'? They might be OK but not able to handle the more aggressive timing and frequency.

If you could revert the tune and see if they are OK, you should be able to sell them and thereby making the upgrade to newer, a less costly affair.

Personally, I don't think they are bad but simply not suited to handle the upgrade.

aeroman

OP said he already went back to stock ECU load and the problem remains.
