Well..... truck back at the dealership after having AEM Flash done. This makes twice it has sat at the dealership for over a week each time. Oh, the dealership does not offer a loaner .... but will gladly rent me a rental ??
Apparently, the flash will eventually cause the DPF to go bad! Service tech said it is a $3000 part, but is covered under the new AEM warranty.
Research shows that only replacing the DPF is not fixing the cause. I asked the tech about this and he agreed, but said that is all is available until an update is done to the AEM flash.
