Since 2012, the nightmares begin with trying to get my 525I smogged, from weber BMW fresno under a whooping $500. Every time the smog is due which is ever 2-yrs the service engine light comes on.... and BMW gives you the code you replace what the code says and then guess what the light comes back on they keep charging you a diagnostics charge of $130 each time and when you get to $500 they now know what the problem is which will cost you around $1000 or so. BMW gave him a code for $130, he made the repair based on their information and guess what it didn't pass smog. So, my mechanic took it back, service adviser not in who handled the car the first time so their is another diagnostics fee of $130, my mechanic tells them fine just smog it. Well it's been two weeks with the BMW service center, they claim to not know what the problem is but they need authorization now for additional diagnostics which would bring the total to $520, and you guessed it the car still hasn't passed smog. I called to speak to the service manger on 2/11, for assistance and of course he is going to look into it and call me back. My mechanic says he was last informed this same thing by the service manager but the service adviser said he would need authorization to proceed with the charge of $520 in order to do another diagnostics??...when in fact all they do is rake up false charges and codes based on the mileage of your vehicle, you can forget the fact that you keep up the maintenance on your vehicle, it won't matter when the time comes to get your vehicle smog be prepared to be scammed by weber BMW in fresno.

525 6-cyl

  • 29,000 miles
Sudden acceleration on a BMW 525I 2004. No previous incidents. While turning into a parking space, perpendicular to the road, in front of a bakery, during the final approach the engine suddenly accelerated, abruptly and without a reason, going over the bump stop. The car ended up in the sidewalk, no injuries (fortunately no pedestrians were on the sidewalk at the time). Luckily the driver had the foot on the break pedal and could take action preventing a crash with the building's door and avoiding hitting the people inside the shop. Car was taken to the dealer and will undergo testing. Service adviser claims no issue like this has happened before, only in Toyota's. not true at all.
