• Coolant, water ingress and corrosion problems at the 0B5 Mechatronic connector aren't uncommon. When dealing with a TCM that won't communicate at all -or- is packed full of random DTCs such as P1893, P1894, P1892, P1890, U0100, U0146, P2850, U0100, U0212 and U0401 please see this thread:

• Some 0B5 Mechatronic replacements may require the dealer network to match it up even though there is no "Locked" or "Component Protection" type fault codes.

• When P17CA is stored in a new Mechatronic unit that does NOT have Component Protection DTCs the Basic Settings procedure may resolve it per feedback in this thread:
