Like several others, I have a problem with intermittent current drain on my car (Audi A4 1.8, 2000-model). I've measured the current to 0.3A, and isolated it to the circut for fuse 15, controlling instrument cluster, power windows and climate control. Have anyone experienced the same problem and have any suggestions to what is the most likely problem? Also, is it possible to test further without dissasembling the entire dashboard?

I have had an Audi S3 (52 plate) since new but since moving to the Isle Of Man have started to experience problems with a periodic flat battery if I leave the car for 2 weeks or so without driving it. It is fair to say that the longest journey I do over here is only about 30 minutes duration so the battery doesn't get the charging time that it used to in the UK, but nobody else seems to be experiencing this problem over here. I have had the car into several garages who can find no fault. The battery was replaced a few months but now I have the same problem again. I tried checking the current draw on each fuse to see if I could detect any obvious problem. Some circuits registered a small current but this is to be expected to run the electronics in standby, alarm etc. Has anyone else experienced anything similar or can give me any advice as to what current I should expect to see drawn on each circuit, for comparison purposes. The fuse circuits which registered non-zero currents with the car standing idle were as follows: (fuse#) 12 - Onboard diagnosis, reading lights, alarm 355mA (all lights off when meas. taken) 15 - Instrument Cluster, Central locking 10mA 16 - Magnetic Clutch / Water Pump 128 micro amps 17 - Heated door locks 55 micro amps 28 - Fuel pump 1.2mA 30 - Sunroof 48mA 32 - Engine Management 0.5mA 37 - Radio 4mA 48 - Luggage Compartment 38mA Cheers, Robin
