1994 s420 check engine light on
Would anyone can tell me that what problem with my 94 S420 check engine light is on. The led blinks 19 times, I reset it 3 times and it comes back the next day. Independent shop said code 19 shows no use (?). My car is still running good. Now it has another code 25. Please tell me before I have to take it to dealer to check. Thanks in advance.

Code 19 = Diagnostic module N59/1
The Diagnostic module (N59) monitors the engine control systems and their ECU's to assist the technician during the check/ troubleshooting process. If the module detects a system/component malfunction, it illuminates the 'CHECK ENGINE' light in the instrument panel.
Code 25=not connected
