Re: 166 2.5 Sportronic questions
there is a fuse in the bulkhead, under the wipers, there is a black plastic cover 8in by 2 in between the two wipers arms, under there are the fuses for ABS, heater/blower and the auto transmission.
There are two ECUs, one for the engine and another for the auto transmission, the engine ones vary according to model year, early ones under the front passenger floor, later ones are under the bonnet. The ECU for the auto is under the ICS and heater, which is why they get wet when the heater leaks. To see if this is a problem, take off the centre console panel with all the padded leather (plastic in reality) odd, only a couple of screws and see if there is any sign of leaking.
