hi all, hope your all well

I have a number of error codes come up using the Launch code reader and im wondering if anyone can some pointers?

FRM (footwell module)/TSGFA (driver door control unit)
030101 no output voltage...... Intermittent

ACS (Car Access system - CAS/FEM/BDC)
8041A8 welcome light repeat lock active..... intermittent

----------------------------
AC (air conditioning - IHKA)

E71459 Signal (torque limitations for crankshaft of air compressor, Dx1b9 invalid, transmitter DME/DDE/EDME........ also States Permanent

801384 Electric Auxiliary heater(high voltage) coolant flow rate malfunction.... also states permanent

801385 Electric Auxiliary Heater (high voltage) coolant excess temperature detected.... also states permanent

801387 Electric Auxiliary Heater (high voltage) reduced heater output.... states intermittent

are these 4 codes linked to the same part being faulty?

2228C8 starter unit, auxiliary battery: aged auxiliary battery.... states intermittent

and finally

118002 mixture control: Fuel are mixture too rich..... permanent
regarding I took my car to a none BMW garage and the engine management light came on after a service, took it back to them and was advised if it comes back on to go to BMW... the light came back on and off to BMW i went, they changed the oil and recoded what they needed to get remove light. But it comes back on?

can anyone give me pointers and possible costs?
