How Jump Starts and Battery Replacement Can Cause Problems With YOUR Vehicle's Computers
This is a subtitle for your new post

Aside from the purely mechanical parts, modern European cars and trucks may be thought of as being highly complex and sophisticated networks of computers, control modules, and sensors which collectively control their various functions. They truly ARE modern marvels of electrical and computer/software engineering that control most of the functions of your vehicle, and they're wonderful....until something disrupts or corrupts them. These networks are very sensitive to electrical disruptions that can burn out computers and control modules, just like all network computer systems, and these can become sticky problems that may impact many of your vehicle's functions. You need to also be aware that potentially problematic disruptions may occur during what we often regard as simple procedures such as giving or getting jump starts or even battery changes. If you own or have owned a home computer, you probably understand that sudden voltage changes or current surges cause problems with sensitive electrical systems....this is why we often protect those systems with "surge protectors". That's all that happens in these cases, even though surge protection measures are often built in to to these systems. Just like with any sophicated computer systems, sudden voltage changes or current surges occur very quickly, and damage is incurred in that short period of time. In this case, sudden power current surges may result in blown or corrupted Engine Control Modules (ECMs), Transmission Control Modules (TCMs), Footwell Modules (FRM), or Body Control Modules (BCMs), and these can result in the memories and programming of these modules being corrupted or lost. Smartkey functions such as starting your vehicle, unlocking or locking your doors, window control, turn signal, and mirror controls are lost, and the repairs of such issues require replacements of blown modules as well as brand-specific reprogramming efforts and, sometimes, creation of new electronic keys. These are not simple jobs, and the fixes can take some time to complete. We KNOW....we've dealt with them before, and we CAN rectify them based on our experiences with them across multiple makes and models of Euros. So, If you're having strange issues, and you suspect "electrical gremlins" after a jump start or battery change, give us a call at (609) 641-3392 or bring your car or truck to our shop at 425 White Horse Pike in Absecon, NJ. It takes EXPERTS to complete some jobs, and we've got them here at Ditmire Motorworks!
