I'm guessing the water could be coming from around the windshield and but I'm actually not sure where the ECU is located on a 2004.
If it is dried out it may function normally or send out to an ECU repair shop.
Hope you get it sorted soon. |

Well.. repair shop for ECU says I need a new one 
Looking for a A1131534979 or A1131534579 ECU.. I suspect the dealer is going to be unobtainable - or stupid priced.. especially seeing as I will need to take the G there and I suspect and pay 300 an hr for service. |

Here's a couple on eBay

Did you send your ECU to Precision? They unlocked my 2000 G500 Ecu.
It may be worth calling them to get a handle on the repair or replacement.

If you can substitute a CLK500 ECU (A1131534879) with reprogramming, that could save alot of money. |
