Mercedes c180 ECU flooded with oil

[Tizz2930]

Hi
Just had news from garage that the engine oil has leaked and flooded ECU through the Loom.
They have said it can cost up to £3000 due to amount of flooding to put right. Car is only worth that amount so not worth doing if this is the case.
Does this sound right? Is there a way to buy 2nd hand parts, can ECU be cleaned up and put back. Any guidance is appreciated

Hey thanks for your response, it's 2005 car. The garage said the camshaft sensors failed and the engine oil pushed through loom into ECU, does this make sense?

Yes.

Known problem with W203.
Too late for your situation but you can get 'blockers' that stop the oil getting into the loom.

Very common fault on those engines. As someone has said above, the oil migrates up the loom from the cam sensor on the front of the engine and makes its way up to the ECU and floods it. On service you could guarantee the vast majority of 202/208 petrol engines had this problem, however most will never show any symptoms and will just carry on with no adverse effects. Some however if the problem is bad can cause issues.

As the car's aren't worth much anymore, if I were you unless you have actual engine management problems would be to just continue driving it, until a tangible fault happens that is directly linked to the oil ingress. There is nothing you can do once the oil has spread into the loom already other than replacing sections of loom which is probably more time consuming than just replacing the entire loom itself. ECU you could clean out but without solving the oil in the loom issue will just keep reoccuring. You can fit the connectors for the cam sensor to prevent any further oil being pushed up the loom.
