Can anyone help me to translate the following fault codes into what I need to fix please?

They have recently been downloaded from my 318i SE (June 2003).

Engine

27C3 Thermical oil level sensor

Airbag

50 Supply voltage

70 Seat occupancy sendor (x2)

51 Fault lamp (AWL)

Airbag

5E1F VIN different

5E16 CAN instrumentation

5DF4 System voltage > 9 volts

5DF7 CAN control module

Instrument Panel

F5 CAN-bus to ASC control unit

F4 CAN-bus faulty

87 K-bus

CE Ambient air temp

There is an airbag warning light on the dash board (probably passenger seat sensor problem) and I know I have an intermittent problem with the rear lights. i recently had the oil warning light come on but this has now gone out as I have topped up the engine oil. The air conditioning does not work (no cold air output). I regularly get the brake warning light and 2 yellow tell tale lights for the ABS coming on together and when this happens the radio crackles/volume reduces and the temperature display goes off momentarily (all happens for 2-5 seconds). So I knowI I have an air bag fault, a rear light fault but I wonder if the other problems are connected to either a faulty temperature sensor and/or electrical problems with the instrument panel/dash board.

Can anyone help - before I have to spend money getting a garage (dare I say even BMW dealer) to help??!

Thanks, Sue.

      E53 petrol fail safe again.

      Morning Stu Long time since I played with a straight six so the old memory might be wonky here so check realoem From memory it is linked to the Air Pump and Vacuum control system. Find the Airpump and follow the Vac lines to the rear of the engine you should find a valve with a plug on top (or end) first make sure all lines are good no splits or cracks check the valve is operating, dont forget there is a non return vale in the system close to the inlet manifold. Hope this helps Dave

      Water leak at sharkfin aerial

      Morning Vic New one to me but I guess anywhere there is a joint is suspect. Like the seals around the rear lights that suddenly start to leak, removing them a good clean and renewing the seals seems to work. Check www.realoem.com to see what is fitted and how Dave

      Rough idle problem

      Morning Billy When was the car last serviced ? The symptoms you describe could be due to an air or vacuum leak, old hoses seals and vacuum lines can start to crack when cold they are stiff and don't leak (as much) when hot and flexible you see the issue developing. Your OBD Scanner needs to be BMW capable a standard scanner will only see critical functions. Dave

      Rough idle problem

      Looking for some help. 2010 116i M sport with the 2.0na engine. When cold, car ticks over perfectly. After about 15 mins of driving when idling you can feel it getting a little bit rough. Nothing too bad, but the longer you idle the worse it gets. No EML. When running car runs perfectly not a flicker. Today left it idling for 10mins after I felt it and then revs started to fluctuate but still no eml. OBD scanner can’t pick anything up. Turned it off and back on and was still rough but only a little bit like when it just starts. Anyone had anything similar or can point me in a direction of where I should start looking?
