Mein Auto: '05 745Li
745Li TCU DC Short

My media system would continuously resetting while on every ten-fifteen seconds. I could not disable the radio since the system would restart and re-energize the radio then shut down.

Bought a fiber optic loop at the dealer and discovered my TCU was causing the continuous reset of the media system. I opened the TCU and found one brownish (burnt from high heat) metal can flat pack capacitor on the top board.

With the loop installed the media system works flawlessly. I don't have SVC or Bluetooth since the TCU is removed. I would love to have Bluetooth again!

Is there shop that repairs TCUs or a source for the metal can capacitors?
