Hello Motor-Talk Community, have configured and ordered for an Audi TT (Coupe TFSI45, quattro , BJ 2019, ACJ000033) at reifen.com winter bikes. Borbet CC 7×17 ET 50 with 225/50 R17. Should fit according to configurator, and I received from reifen.com a message the wheel-tire combination would fit and send to partner operation. Today this should be mounted at the Premio partner. Result: the wheels do not fit, allegedly because of the brake. They are looking for a solution (purple plate) n) and report, date in approx. 4 weeks. My mood was already in the basement. Note: The standard brakes with which the car was delivered are mounted! Then I called the Audi customer service. When I explained the thing I was already strangled: “Look in the COC paper, there are all permissible wheel-tire combinations in it.” My question about the brake in the car was ignored, for that there was the hint I should go to an Audi dealer. They are j a sooo much more competent! Then my call at reifen.com. “According to expert opinion that fits!” “We take nothing back!!!!”, that was the most important sentence! So I think if I buy something from which the seller assures me that it technically fits, and then it doesn’t fit, that’s not my problem! My attempt technically to figure out what went wrong then went wrong in nothing. The customer consultant was held back and stopped the conversation. I should measure the brake, and d if I don’t want that to be all in vain! Too bad, actually I just wanted the error to be investigated and eliminated. Everyone would have benefited from this, but reifen.com does not seem to be interested! Apart from the fact that I imagine solution-oriented conversations differently, my question to you: How reliable is such an online configurator? There also data about the size of the brake would have to be noticed, otherwise it doesn’t make any sense. Is the TSN+VSN input i n the configurator is not clear at this point? Do different companies have different configurators or do they all use the same? I’m looking forward to your answers, I just want to explore the cause! Best regards drivers35i
