W205 steering wheel vibrates between 65 and 70 mph

[Series1boy]

Hi, as per the title just bought a 10 month old 65 plate c class w205 amg sports premium plus and steering wheel vibrates between 65 and 70. It's been into MB Sheffield twice and they say 'it's within spec'. I said this is boll.. and they want me to go out with a technician but they nothing us wrong. The car has 4 brand new Pirelli run flats and have been balanced twice now.

Any ideas?
Cheers

Rotate them front to back , left to right and report back - seriously. you may have slight buckling of the alloys.. I had this on another car, felt a right RS as I read the riot act on the dealers only for an Indie to rotate and figure out that I had two badly buckled wheels...

Road force balancing?

Wheels can be badly balanced by the average tyre shop, who just spin them on a machine.

A large tyre specialist can use road force balancing to give better results. Down South the place would be Micheldever tyres, but there'll be an equivalent near you. Very big tyre specialists are better than main dealers for tyre/wheel issues.

It may be a faulty new tyre - the old quote is that you can balance a square wheel but that doesn't mean it'll drive well on the road.

As our friend points out, switching wheels from to back, will confirm whether the front wheels are out of balance - but it's not a solution because it just moves the imbalance to the back, where it's less noticeable, but still a source of long term wear.

Get a second opinion from Europa in Sheffield. Theyre autheerisd Merc repair centre for warrenty etc. Also cheaper than Merc for services and the exact same mobilo given

Badly balanced wheels or warped disks.

Thanks all. I've only had the car 1week so Jct need to sort it. I'm going out with 1 of their technicians on Tuesday to demonstrate the issue.

With regards to swapping the wheels, are the rear wheels not wider on the back than the front wheels; it was the case on my w204?

If it isn't the balancing then my money is on buckled wheels. I had this on my ML350, the dealer kept saying they could find nothing wrong and it took 4 dealer visits to fix with new wheels.

What gets me is why for the sake of a few hundred pounds the dealers don't just put new wheels on and see if it fixes the problem rather than trying to wriggle out of it and hacking off a customer.

I think flowrider99 is spot on - I had this on my car too, and because it would do it between 80-90 mph, my local MB wouldn't even look into it ...

Went for a full wheel refurbishment*, and it turns out all four wheels were buckled, three slightly and one - quite badly.

Not a hint of vibration now.

* It was actually a like for like swap - brilliant service, and took less than an hour at First Aid Wheels in London.

i spoke to the sales manager today and he confirmed 1 of the wheels was curbed before I purchased the car and they had the wheel sorted before I picked it up. I think this is the issue and will demand a new wheel but also they need to check if they any of them are buckled first. The repair is top notch BTW and looks like new...

I had the same issue on a Saab I owned 6 years ago and it was a buckled wheel so I'm confident it can be fixed and not 'within spec' which is total crap for an brand of vehicle in this day and age..

Driving the negotiation

It's all a matter of driving the negotiation and not settling too easily.

Insist on a new wheel and get it. But don't be surprised to see that your old wheel will be reworked and then put on another car.... They won't use it as an ashtray.

Quick update. I went out with their service manager at Jct Sheffield and he couldn't feel the issue. I confirmed I could and they gave me a brand new car, same model with same wheels to test drive and it was perfect. So they took the wheels and tyres from this car and put them on my car and they only had around 150 miles on them and the car is fine now.

However, I still feel a vibration on the accelerator at 70 to 75 and I think this is just the M1 motorway condition near Sheffield that is causing this at high speed, because when I go on new laid tarmac portions it stops. this is normal I think and can live this with the main issue of the vibrating steering wheel now rectified...

I can't fault Jct for sorting the issue and they genuinely wanted to help..
