Glad to see a General Merc forum here as limp mode seems to be a common problem in many models. Mine is a C220 W204 2007 diesel, but that is of no interest. My iCarsoft MB II messages are:

22DD-000 No CAN msg from N15/3 (ETC/EGS) control unit,
U010087 ECU Comms malfunction,
?? Trans. control module fault - no ECU connection,
B275013 The squib for sidebag driver has a malfunction, open circuit, 530108 CAN N2/10 restraint faulty - both related??
B210C16, B219116, B219500 Power supply outside range, limit avalue not attained, 30g circuit outside ..., 30 circuit < 8.5V
Battery shows 12.3V, so that is sufficient, probably all related to PREFUSE PROBLEMS and F32 relay?? Amazon are falling over themselves trying to sell you second-hand modules,
B224B00 CU rear signal acquisition - malfunction.

If the SUN messages are similar at a Merc stealership, I am wondering what they are going to look at first. For the first error Google claims a solution, but that site wants $50 with little guarantee as indicated by the phrase: " ....... we can only give you what is on the server". I don't have a black belt in electrickery, but < 8.5VDC means any CU (control unit) will malfunction and may trigger limp mode?

How did you get your limp mode fixed? Thanks.

 

Hi, Glad to see a General Merc forum here as limp mode seems to be a not unusual hassle in lots of fashions. Mine is a C220 W204 2007 153k km diesel, but that is of no hobby. My iCarsoft MB II messages are: 22DD-000 No CAN msg from N15/3 (ETC/EGS) manipulate unit, U010087 ECU Comms malfunction, ?? Trans. Manipulate module fault - no ECU connection, B275013 The squib for sidebag motive force has a malfunction, open circuit, 530108 CAN N2/10 restraint defective - both associated?? B210C16, B219116, B219500 Power deliver outdoor variety, restrict avalue now not attained, 30g circuit out of doors ..., 30 circuit < eight.5V Battery shows 12.3V, so that is sufficient, possibly all associated with PREFUSE PROBLEMS and F32 relay?? Amazon are falling over themselves looking to promote you 2nd-hand modules, B224B00 CU rear sign acquisition - malfunction. If the SUN messages are comparable at a Merc stealership, I am questioning what they're going to observe first.
