Hello. Hope someone can help me as I am needing some information about my Freelander TD4 2004 model, while looking for a wiring fault I removed the top cover from the box containing the ECU and fan motor to discover it has a small amount of oil in the bottom, does the ECU have oil inside it and it has leaked out? is it supposed to be there? it is NOT engine oil as it is clean almost new looking, if it is out of the ECU what can I put in it? High Voltage transformer oil?
Thank you in advance
