I've heard similar complaints before, but not from this particular service. Had a Daytime Running Lamp (DRL) out on my 535xi and took my car in to get it replaced under warranty. Rather than just replace the bulb, they actually replace both DRLs and "reprogram" the car, supposedly to lower the voltage delivered to the lights. Whatever they did in the reprogram, I swear my car is now performing like crap. Not pulling nearly as strong, poor throttle response, UGH!

Is there anyway to get back to where I was, other than an aftermarket tune or flash?

 

wow my car feels the same way after i took it in for new bushings and the valave cover gaskets under warrenty... i asked them why does the car feel kinda not as torky or kinda like the gas pedal is kinda hard? they said "we did nothing that would make the pedal hard".

looking for some reply for this also will keep a eye on this.

 

dont you hate that. and even if the dealer did some other programming or updates on your car, they more than likely would not tell you, and definetly wouldn't undo it.
