Vehicle Fitment & Part Numbers Part Numbers: * 12147616431 (Current) 12-14-7-616-431 (With dashes) Vehicle Fitment: This DME is commonly found in the following BMW models equipped with the N55 Engine: BMW 135i / 135is (2011–2013) BMW 335i / 335xi (2011–2013) BMW X1 xDrive35i (2013–2015) BMW X5 xDrive35i (2011–2013) BMW X6 xDrive35i (2011–2014) Common BMW N55 DME Failure Symptoms If a BMW is experiencing these issues, the DME Control Unit is likely the culprit: Misfires on Multiple Cylinders: Often caused by failing injector drivers within the DME, even after replacing spark plugs and coils. No Start / No Communication: The vehicle cranks but won't start, and diagnostic tools (like ISTA or Autel) cannot establish a connection with the Engine Module. Internal RAM/Processor Errors: Fault codes such as 101008 (DME, internal error) or generic "Internal Control Module Memory Check Sum Error" usually indicate hardware degradation. BSD Bus Communication Faults: Issues communicating with the electric water pump, alternator, or oil level sensor can sometimes be traced back to a localized circuit failure inside the DME.
