Electrical problem and INPA error codes

[ase542]

Hi,
I wonder if anyone can help me with these INPA codes:
SFZ 9af6 70
DDE 46d3 48
LM e518 64
Kbm a411 62
Cid e5c4 60
Klima 9c50 64
9c54 62


The symptoms are:
When i use the right turn signal, the trunklid opens
When i put the lights on, all kinds of errors accures,
Servotronic,ABS,Stability control,Window trap contol, and so on.
The gauges also are showing pendling values like 30-40 when i'm driving 35.
And the interior lights and stereo volume are sometimes pulsating.

Any ideas?

The car is a 2005 530D Touring

Have the charging system (battery, alternator, IBS, ground connections, and related wires) checked.

Take a voltmeter and check the voltage when the engine is not running, and then take a reading while the engine is running.
Fully charged battery (while engine is NOT running) should read 12.6V. While the engine is running, the voltage should read around 14V.

12.0V reading (or below) while the engine is off means the battery is dead; you will need to recharge the battery.
Similarly, under/over voltage while the engine is running (due to bad voltage regulator) can cause lot of problems.

I have changed the battery and checked the voltage after that,about 12.5 and 14V.
I have also repaired the wires in the trunklid.

What wires did you repair? Near the trunk lid hinge? Did you replace the battery exactly same as the original one (with respect to Ah rating) and did you get it registered? Did you try to erase the codes? If so, do they come back again?

The damadged wires was mostly ner the hinge, in both sides. there was also damage inside the trunklid in 2 places.
Battery is exactly the same as it was before, i did not get it registered.
I erased the codes but they immediately came back.
As soon as i toched the lightswitch about 20 more errorcodes appeared.

did you resolve this issue? I replace my headlights after an accident and now i'm getting this error, I replaced with exact part numbers
