hello I have a problem with a mercedes sportcoupe car ? affixed to part quietly it gives me no error with autocom the problem that if I leave it stops 7/8 hours I find myself with the battery completely to the ground,I restaurant the battery with a new one the same amperage,I have disconnected both radio and any other thing possible in practice now ? as if it would be the original alternator charging then not ? a problem of charging ,if I detach the battery and I leave it stops the day after in the riattaccarla part safely can you give me some advice?

I just redid a diagnosis with autocom and gives me these 2 errors P1481 candle incandescent and P1664 booster heater electronic,for the first ? a spark burned the second cos

I believe that it is a supplemental heating electronic, but I can be wrong

[elettro72]

thanks tom79 do you know where it is and if you can? off? maybe ? the one who breaks

[munro]

must be the so-called "solutions"....looking in the engine compartment, a large rectangular box with attached heating pipes and a species of the muffler...I think that for? can't remove..because being connected to the control unit of the climate, I believe that after you will? not even the hot air...or the defroster glass....

[munro]

correction..the heater in the w203 is located between the front bumper and the wheel to the right....

[Tom79]

if you get error maybe ? blown any fuse.. and the ecu does not find it, and you will report...

[Tom79]

Made a search on the web with the code d error, it may be a false contact on the fuse box, due to oxidation, by any chance do you ? entrance of the water??

[elettro72]

so guys I have installed now the wis on your pc ,no ? entered the water,it started 2 days break,until then everything is ok,if I remove the fuse for the climate I should to be in place? thanks also to munro....with autocom now I have no error? if I go on the ribbon-the heater does not let me go ,but ets heater can not delete? under the fuse or rel

[Tom79]

I believe that it is under the fuse, you can do a test and remove the fuse and then see if the diagnosis you detect error....
