Help Computer Malfunction /warning Lights!!

O.K A LITTLE BACKGROUND: TWO DAYS AGO I WASHED THE ENGINE (VERY LIGHT WATER LOW PRESSURE, COVERED THE ALTERNATOR). YESTERDAY AFTERNOON GOT A WARNING LIGHT "CHECK ENGINE, EMMISSIONS RELATED FAULT" O.K BAD OXYGEN SENSOR, I DROVE ANOTHER 30 MILES HOME NO PROBLEM. THIS MORNING DROVE 35 MILES TO WORK WITH CHECK ENGINE LIGHT ON STILL, DOING ABOUT 80MPH MY DSC, DTC, ABS, YOU NAME IT ALL KINDS OF YELLOW WARNING LIGHTS LITE UP. SO I SLOW DOWN AND WHILE PULLING OVER I GET THE MESSAGE "DRIVE MODERATELY..." SESSAGE, THEN "TRANSMISSION IN FAILSAFE MODE". I COME TO A STOP TRY TO ENGAGE PARK WONT GO, SHUT DOWN REMOVE KEY, THEN RESTART NOTHING! CAR STARTS RIGHT UP NO MORE WARMING LIGHTS EVEN THE CHECK ENGINE LIGHT IS OFF. COULD THIS BE DUE TO CLEANING THE ENGINE?, i GOT MY HOOD OPEN RIGHT NOW JUST IN CASE.
MY CAR IS 2004 745I 82,000K MILES
WOULD APPRECIATE ANY FEEDBACK

if any moisture even just vapor reached the fusebox-relaybox this could be your problem and yes engine washing will cause this open up your fusebox and see if any signs of moisture are there

Golden rule #1... never clean a 7 series engine yourself or any other late series BMW come to that, BMW can do it in their valet bay as they have special covers for various things and very special cleaning fluids that don't attack the electrical system, a friend of mine steam cleaned his e38 1999 750il, the bay looked stunning.... it never started again and he changed loads of things, in the end he broke it for spares......leave the hood up and pray for some major sun or you could try blasting it with compressed air if you have a compressor....

lucked out

well I guess I lucked out, drove home from work yesterday with no problems. The only reason I did it was because I used that Black Magic 2in1 engine shine, that states wery "little water needed" and "safe for all engine conponents" what a crock!
Thanks guys for the fast response and advice.

I cleaned mine with WD40 about 4 cans, just spray it where you want and clean off with some rags, its handy if you do have a compressor to blow out all the dust etc..., it did take me most of a Sunday afternoon, but the results were worth it,for heavy grease and oil you can use a cleaner like 'Gunk' (which we have in UK) and then wash it off with a hose but not under pressure or spray and not directly on anything that's electrical...
