Yep, for the ML350. I have them here in the garage complete with $248 worth of unnecessary TPMS sensors they insisted I needed.
turns out the ML TPMS system works off the ABS speed sensors in the hubs)
When I went to order for the BMW their site did the same thing (saying I needed $212 worth of sensors to make the system operate.). Lucky for me I had asked the BMW dealer if his pkgs included the sensors and thus found out they weren't required. I then checked and found out I had bought them unnecessarily for the ML last month (and I think for the Mini 2 years ago!). When I called Tirerack to complain about the inaccurate information on their website the response from Cust service was basicly "too bad"
That definitely seems like a major screw-up on their part, and I'd be pissed too. That being said, I've ordered twice from tirerack and had very positive experiences both times. The second time in particular, I was looking at a specific rim that they didn't list as a proper fit for the Elantra Touring (a 16 X 6.5 rim, with the proper bolt pattern and backspacing). I phoned one of their reps, who contacted their engineering dept and they double-checked the CAD specs. Turns out it appeared to fit fine, they added it to the car configurator, and those are the rims I bought. I put them on last weekend, and indeed they fit great. So I thought their customer service was great - but there's no TPMS on the ET, and I didn't have to spend an unnecessary $248, so I can see why you don't want to order from them anymore...
And chance the TPMS sensors can be sold on ebay or kijiji? Or are they specific for Mercedes, and not needed by any other owner?
