green A8

I got a phone call at the anti social side of 8Am this morning, from a relly who runs my old B5 1.9TDi (AFN) Avant. She was in a bit of a panic, as it would seem that the car was bleeping at her three times over and over, the engine had not been started this morning , but the car was run yesterday and gave no problems at all. As she only lives a couple of miles away rather than faff about on the phone, I simply jumped in the A8 and drove over to hers.
So, lets start at the beginning. Three chimes, as you will no doubt know means 'Danger' stop car and investigate one of three things the fault is indicated by the DIS as either coolant oil pressure or brakes (ABS) It can also indicate a weak battery usually just after start up. But this car hadn't been started.
I had a look underneath for any oil slicks or similar, then I opened the bonnet and checked the battery a healthy 12.7/8 volts were lurking in there. All levels of oil, coolant and brake fluid, were present and correct. Next I jumped in the car and turned the ignition on, without starting the engine, yep the infamous three clangs of doom greeted me and repeated themselves several times even though the engine wasn't running! (Just to get the point across that a problem existed!) But nothing on the DIS at all, no clue as to what the blazes was wrong! The check button performed as advertised and the DIS displayed all faults, both yellow and red. Next up I checked the electrical connections to the ABS pump, the water header tank and the oil pressure switch. Again nothing seemed to be amiss. So I started the engine, nothing for about five seconds then the chimes started. I took the car out of the garage and ran it about a mile or so up the road at first it chimed it's head off, then suddenly it stopped!
I haven't got a clue what the fault if any was. The A4 is now back at my place, my rellie is enjoying the delights of a 4.2 V8 for a day, so she's a happy bunny! I've plugged in and checked the diagnostics, no faults whatsoever were stored, I've not a clue as to what caused this noisy mayhem. I then drove the car about ten miles or so without any further problem. I suspect it COULD have been a bit of junk tripping out the oil pressure sensor (had this before on an A6, a tiny bit of muck clogged the sensor. One new sensor fitted = no more bleeping. At least that car told me what was wrong with it via the DIS though) BUT, as there was no info displayed at all on the DIS of todays problem car I can't confirm this. I just wondered if any of you Ladies and Gents have got any ideas as to what caused this? As a precaution I'll change the oil and filter and see if I have another oil pressure sensor to fit this car.
All ideas and suggestions welcome.
