You need to open the DME, it is not that hard as I recall. If you sprayed contact cleaner into the connector with the connector facing up, all you did was rinse and spread more oil inside the DME.

Also not 100% that the contact clear will cut the oil like brake cleaner.

You should keep the OBDII interface in the console or glovebox and connect it up when the lights come on. The problem is a generic OBDII tool WILL NOT communicate with the ABS or other modules.

You can also connect the tool up for each drive and it will Log when hopefully the problem occurs, the OBDII App will also Log the charging Voltage.
