Hey Guys,

Just picked up my car last night. Love it but the realized the CEL was on. Pulled the codes down and it says the heating element in the 02s are shorted to ground on all 4 sensors. I am a Porsche Tuner so I am not entirely familiar with these cars...yet. I can't imagine that all four elements are out. Can someone share their experience with this issue if they have seen it before? If it was a reading error I would assume MAF but tat wasn’t the code I got unless my OBD reader is putting the wrong generic code to them. It pops on when you first start it which would indicate the heat up cycle is not working but again I know little about these cars.

Thanks!

 

yeah thats weird that all would not be heating. I would start by checking the fuse block under the hood by the battery.

 

Not use to that. All the DMEs in the german cars actually run the heater 12+ circuit through the DME. That is what happend though, fuse is popped and I assume one of the sensors is causing it. I can replace it and of course it pops again. So I guess I will just unplug one sensor at a time and see when the fuse stops popping. Anyone know where the connectors are for those. I would assume the firewall.

 

Not too sure, but here's the FSM
