I have had an ignition module failure on both of my V12TT's. The car was not disabled but the failure was quite noticable. I replaced the motor mounts on the SL600 because they were starting to collapse, it was inexpensive. All other repairs were not related to the power train, such as the Vario Roof cable replacement. The rear strut failures on the S65 could be related to the use of the power available. They are almost $3k each if not under a warranty. Our SL600 has been very reliable and is a really great car to drive in the long term; that is why we decided to buy another one.

I think it depends on the car, and the care and feeding that car got before you.

Yes, and I've been thinking of the ECU tune!
Could it be that when you do the ECU tune, it starts consuming these ignition parts..?
At least in my cases, I believe the cars that got that ignition problem, were all tuned...

Of course, not saying that ALL ECU tunings destroy these ignition cassets/modules or anything!
Just saying that in my case, there's a pattern...

Or have anyone experienced this with a stock V12..?

There is nothing better than hands on experience, I owned both so as far
as I am concerned the 63 is faster, they quote SLS at 4.1 but I have seen varying figures from reviews.

Just did some maintenance on the M113K engine and had similar problems. The coil packs might be getting a bad rap. The modules are made by Bosch and are epoxy sealed. Potting electronics is typical practice for harsh or mil spec environments. My tech and I came up with an easy solution but I want to check on the application to the V 12 before I make any pronouncements.

Nope. Both UK and US road tests put the 55 faster.

I don't believe everything I read, anyway my 63 has been re mapped with
K&N so it will definitely be faster than a stock 55. 55 quarter mile times aren't
that good on stock cars.

Sharkster

Didn't own both, but drove both. I agree to the official figures and to all road tests.

Stock 63 exhaust note may sound more wicked, but 55 is definitely faster.
Seriously, no (!) doubt about that...

drabux

I don't believe everything I read but neither am I selective in what I choose to believe due to cognitive dissonance and buyer's remorse.

Remaps of the 63 don't yield much extra bhp. e.g. Eurocharged gets 15 bhp. I doubt that extra would be noticeable or make any difference on a 1/4 mile run.

For the newer members...

Talking to Sound8, is literally like talking to a brick wall. He lives in a fantasy land where he belives the SL63 is the best car ever created, an ECU tune will yeild gobs of HP and TQ, out of his N/A V8, and K&N filters are a god's send. Seriously, just skip his posts, and don't waste your time.

Anything that adds power is a good thing. I owned a stock 55 for 5 years
and I know how fast and at what point it would be going, and my 63 is faster.
What let's the 55 down is the gearbox, quite often when you buried the
throttle the gearbox done nothing ,or only change 1 gear if it was too near to the red line. The 63 on the other hand responds instantly to ANY input, and will change right down with only 500 rpm to go, this is one reason when driving on the road it's the faster car. At least I don't film myself breaking a
record, and post it for all to see, I am far too modest.

I found myself smiling, while reading this..!

If living in fantasy land is cars being a large part of your life, then your right,
I am.However there is something that we will never agree on, and that's because you live in the states and I live in the UK. In the States the quarter
mile time is the daddy, pure acceleration, that's because you have long straight roads and few bends. That's why cars in the States are all about muscle,they always have been. In the UK we do care about power but handling is equally and sometimes more important than straight line speed.
If you remember I bought up the subject of buying a SL600 and tuning it
rather than get a SL65. Your 600 is indeed a very quick car, but on a track
it would be annihilated by something far less powerful but set up for handling.
I can remember 30 years ago when Mustangs raced Mini's that's V8 muscle
vs 1000cc mini, and Mustangs won on the straight only to be overtaken on
the bends, of course there was power to weight as well. Any way getting to the point I reckon the 63 would beat your 600 on a track, the handling and
gearbox would see to that. Also it takes far more talent to become a good
F1 driver than a Drag car driver, and I don't mean that as an insult. Yes my
63 is a great all round car, and I can't see what I would change it for, unless
of course I lived in the States.

Was somebody sitting on your face.

maxabo

Excuse me, but does one sitting in your face make you smile..?
I can't make that connection. At all.
Or if that was a joke, I don't get it...

I've had a lot of V-12 cars and like them. Ferrari, Lamborghini, BMW and MBZ. I had an S-65; great car. I drive an SL-55 as a daily driver now and love it. It's not as fast perhaps, but plenty fast enough, and has an 'edge' that the 12 bangers don't. If you want leather everywhere plus alcantara, do what I did: get the designo model. Mine is designo graphite and I love it. Also, no matter how you cut it, 8 is less to maintain than 12.

grane

Silly girl,sl63s are for kids.

grane

I like them all, in spite of my derisive remarks.

Please consider a CL55, 600, or 65 after 04 that meets or exceeds CPO specs.
Similar performance, better inside environs. Drive from Boston to Montreal with another
couple and everyone arrives refreshed and whatever speed is legal and prudent. Pure silky sex. And you can stay more than one night.

here is a comparison between the SL63 AMG and SL600

Do you have any updated info on the modules being bad and not the coil packs????

AZBENZ-CTSV

I just went thru this choice. Drove numerous SL55 and SL600 cars.
In the end for the same used price, found a nice low mile car 13k on the dial
SL600 that I ended up with.
Overall i just think it's a better car with way more mod potential for less $. Both cars are outstanding in my opinion and great "bang for the buck" cars at the current used prices.

IngenereAMG

Now you just need a Veloce Performance tune!!

Are you in AZ? If so, have you been out to our monthly Cars & Coffee, the first Saturday of the month in Scottsdale?

LukasBMW

I've been meaning to attend.

But is it May 19th this month? This website says it is:
