Speedometer stopped working too


Hi everyone. Been a while, but have just been enjoying the wagon with no problems to note, til now. So leaving the grocery store I go to hit the gas and nothing happens. Glance down and my instrument cluster looks like this. First time I've had a Benz in limp mode, and noticed it's not a speed governed systen like Audi. It wouldn't let me go above 1800 rpm, but would build as much speed as you could shifting at 1500 to 1800 rpm in every gear. SA found a defective esp controller and ordered one. However, when the car was up they noticed that the inner tread of both rear wheels were down to cord. Outer and middle looked fine which made it almost impossible for me to notice. These were the stock pirellis, and I had to replace the fronts at 7000 miles, now the backs are cooked thru 11k. But now I can finally put a full set of pss on. Sorry tire pic is hard to see, but it finally rained here yesterday. Side note, with balding rear tires and all esp nannies on, still inadvertently got the wagon sideways this morning on wet streets! Think I'm going to spend the rest of the day looking for empty wet parking lots.

I just (as in today) replaced the stock Pirellis in the front at only 7,500 miles. I knew the tread would not last long, but this greatly exceeded my expectations. The Pirellis in the rear still have life so I left them alone.

HKJay

Yea, Pirelli didn't last nearly as long as I thought. And I hate having unevenly worn sets of tires. Hopefully the michelins wear more evenly

I'm on my third AMG and every single one of them has wore the inner shoulder of the rear tires like that.

I have a 2016 sedan 10.2k miles hard driven. Front and rear Perelli are wearing perfectly even... just did my service A. They did a alignment and the rear was off a tad. My thread life is 20% left. Then will do r888's or PSS.

gotta love that amg negative camber

chiromikey

I played with so many settings on my first E55 and every type of adjustable set-ups from bushings to arms. These cars do not like their negative camber being taken out. If you get the alignment closer to neutral to decrease inner tire wear the car got unpredictable under heavy acceleration.

Btw, I advise everyone that values their life to stay away from the kmac bushings in a car with this much power! Maybe they're better now but I won't chance it!

Totally normal with the camber on these cars. Checkout your front tires by turning steering wheel all the way in. Front tires wear on the inside edged even worse. Outside of tire looks like you have half of the tire left while inside shows cords.

If it helps I just switched over to Conti Extreme Contact DW's and they perform well, wear well, and are cheaper than the standard stuff like Pirelli and Mich PSS.

gaspam

yeah that's why i never messed with mine on e55 or c63, both of which wore the insides pretty badly due to the negative camber ... the e63 has not been as bad in that regard but the wear is still there

chiromikey

True, my 63 has been the best of the bunch so far. I've put off lowering it a little because I don't want to mess with a good thing...

Astolfo

Funny, I went to the track and literally chewed the outside... I was going to ask about adding camber.

HKJay

I used to hear numbers like 18 to 20 k on a set of tires. I've gone through 6 tires in 11k miles. Daily driving, no track. What are you guys getting out of the pss?

HKJay

My fronts wore perfectly even, but they wore all the way down in 7000 miles.

gaspam

if you drive nice, 18-20K should be doable on these cars... I have about 12K on my conti sportcontact5ps and they are still ok on dry buy getting sketchy in the rain... I drive pretty hard so i think i will only get about 13K out of mine... still a lot better than what i used to get out of tires on my e55/c63

vdubpower

24000 out of pss so far, driver side front has a little inner cord showing as i posted in one of my previous post...annoying

hoping to keep these few months, interested in those Michelin ps4 that the new e63 is getting but i think sizes wont work

had 18000 on my original p0 for the rear, but those were really worn, fronts fine

All AMG's are set up from the factory to wear inner tire edges. It's likely a combination both neg camber and in-toeing. Keep an eye out for inner edges of all tires.

OK, OK.... but if you do there is a free kit waiting. As we have not been sitting still. Saw and have met the challenge of a “bolt-on” rear Camber adjustment facility to suit the alloy rear arms on AMG models. So once locked in required camber setting – will withstand 600 plus HP and get this power/traction to the rear wheels just like our kits for steel rear arms.

Designing, creating always comes with both queries and criticism. Being the 1st and only company to manufacture front and rear adjuster kits to suit all Mercedes models we therefore do get our share!

Background is there is only front and rear Toe adjustment on these models. No full Camber and Caster facility to adjust the actual tire contact angle.

You can purchase OEM (for the front only) “one offset position” fluted bolts. But these are inaccurate with the one position only providing a minimal .3 of one degree (1/8”) Camber/Caster change!

We saw the need therefore to return to the early ‘90’s and restore full/ongoing and precise adjustment capability.

The unique K-MAC patented design kits provide up to 4 times the adjustment range of the one position fluted bolts. Replacing the 4 front and rear highest wearing suspension bushings at the same time. They’re single wrench and precisely adjustable – accurately on car “under load” direct on alignment rack!

Allowing to fix it right the 1st time....costly, premature edge tire wear/traction. Along with the front also correctly resolving steering pull and with increased brake and steering response. Rear kit also included “extra Toe” to provide for the new camber facility.

Catering for “individual driving conditions” – high cambered roads, load carrying, altering suspension height, fitting wide profile tires/wheels, high mileage/sagged suspension, curb knock damage or performance driving/reducing understeer on track days!

All W212 including AMG models:
FRONT Camber and Caster #502916K $480
REAR Camber (& extra Toe) #502226K $480
