Hi to all

would love all those that know (or think that they know) to chime in here....

The www.mercedes-amg.com site lists the CLS 030 package as having LSD, yet there is nothing in the US literature, sales stickers, option details etc. indicatting that it has the LSD

Informed guys like Shiznick say that the Window Sticker (indicating the differential oil must be replaced at 1800 miles) and the Service booklet (indicating that the differential oil must be replaced between 1000 and 3000 miles) are teh proof that the 030 package has the LSD. Note that both these warnings are 030 specific.

So my question is - if we dont have the LSD (as some of you in the know??? insist), then why do we have specific warnings that relate specifically to the differential, that only appear on the 030 CLS's?

Not looking for speculation, looking for informed answers. I have emailed Rob Allen at AMG on this as I would like it cleared up

If you have it clear in your mind please set me straight and inform me of your source (part #, dealer insider, AMG insider etc.)

Looking to clear the debate.

Hoping this wont deteriorate into the US M5 Launch Control fiasco

Maybe my CL55 is different relative to how ESP works ... but, a quick, dirty, and valid test would be -

1. Turn ESP off
2. Power brake to 2000 RPM
3. Release brake and floor it

If it doesn't have LSD, it will "instant up in smoke uni-track" one of the tires (probably the passenger side). This is what my CL55 does, and my CL55 doesn't have LSD.

I would expect an LSD 55K to instant up in smoke both rear tires.

Stiggs

I agree...this would be the best test.
we need two people with CLS55's. One with 030 and one without. Line them up next bto each other and smoke 'em. there's all the proof you need.....is this correct?

...or you could have an MB Tech open the diff and look.

The 030 Performance Package for the CLS55 that comes to the USA includes these compnents:

19" AMG multi-piece twin-spoke light alloy wheels
(FR 8.5x19 ET 25 255/35R19 RR 10x19 ET 28 285/30R19)
Vmax increase to 300kmh
Multiple-disc LSD including reinforced final drive unit
Internally-ventilated composite front brake discs (380mm x 36mm)
AMG ergonomic sports steering wheel in black leather/alcantara

There is no question in my mind.

Kar don

yep there is nothing to debate, has LSD.

I will have my tech show me the LSD when I go in tomorrow to have the differential fluid changed. Damn already 2K miles on the biatch.

siswati

Looking forward to your report. Take a camera and snap a pic. If possible please get a part # so that we can compare to the standard CLS55 Diff.

many thanks

ClayJ

Drive Harder! Drive Faster! Drive More! Become One with that "biatch" - and love every minute of it! LOL

Um, even without LSD, sometimes both tires will still manage to break loose depending on weight of the car, tires, and friction of the pavement.

I agree, all evidence points to LSD being a bonafide component of the performance package. (I have one on order.)
However in my conversation with USA AMG folks, when reviewing the package components, they also said that the rear wheels are NOT 10", but only 9 1/2".

ClayJ

That's a good point I have heard that from someone who took delivery (FR 8.5 & RR 9.5) -- I need to change that in my 'notes' file. Thanks.

Tony007

Well, that's interesting because I just went to the garage and took a tape measure to the rear wheels on my 030. The rears "wheels", not tires, physically measured over 10" more like 10.5". I would be interested to know where on the rims the manufacturer takes their measurements.

Anybody know?

ClayJ

Ah Hah! Another 'mystery'? LOL

Roupin

The wheel and tire sizes between the "standard" 55K and the 030 are identical, at 8.5/19 front with 255/35 and 9.5/19 rear with 285/30.

I have a single page "handout" that I picked up from my dealer regarding the CLS55 030, and it specifically lists the LSD as one of the benefits of the 030.

That's straight from the horse's mouth. Consider it 100000% proof it has LSD.

Can Drive 55

The measurement would be made on the inside of the wheel where the tire makes contact with the wheel.

Nice power meter Mr. J.

Roupin
Could you scan and post that dealer handout please
thanks

ClayJ

Not much gets by you does it? Even at 158 you're pretty attentive...LOL

You might just make a good Mario Limodretti after all.....

Can Drive 55

Occasionally I pay attention and sometimes just jump off the page at me. Makes editing at work easy, don't you know. In this case, that thing screamed Bug eating Volvo. Those Sweedes make fine Creme Broulee', don't they? I think I could handle the limo just fine.

I posted this in another 030 thread, but it looks like it needs repeating. If you want to verify whether or not you have LSD, do this:

Elevate both rear wheels off the ground. With the parking brake off and the transmission in neutral, rotate one of the rear wheels by hand. If you DO NOT have LSD, the other rear wheel will rotate in the opposite direction. If you DO have LSD, it will rotate in the same direction.

This is a proven technique that works on American cars. I see no reason why it wouldn't work on German iron.

siswati, I don't have a scanner at home, but "FloridaE55" had scanned it and posted it in another thread a couple weeks ago.

Here is the picture. It's a little blurry but you can make out the words. Look at the 2nd last "feature" on the right side of the picture, it says "AMG Locking Differential"

FloridaE55

Yep, that was me..
I can also explain the confusion concerning the rear-wheels (9.5 or 10). They should actually be 9.5. The confusion was caused by MBUSA as they were telling everybody the rear size would be 10, but just before the package went into production, they changed it to 9.5. Please refer to my post "Final content of 030-package" where I pointed out that they changed this size:

Content of 030

Tomorrow I will know whether or not the car has LSD. I personally feel that its there as does the literature.

Getting the rear diff fluid drained and filled tomorrow afternoon.

MB Fanatic

Its official CLS55 with 030 has LSD. I saw it as the tech was draining the fluid. He also replaced a rear diff seal as it looked like it was going to start leaking soon.

Now lets put that to rest haha.
