Hello together, have problems with the power supply with my SL350 R230/Mopf 1 (2006). To read under: Board power problems: 9002 undervoltage KL15R/Kl15 at the R 230 At MB and Bosch various errors were read out (CAN / SAM /… Undervoltage Kl15R/15) of which I estimate the undervoltage error as a cause (EZS problem) After which the error only occurs when the friendly far away I wanted the error over an OBD dongle (HHOBD from EXZA) with Android SW “Carscanner” after The things are running but the EZS does not seem to be supported. I was probably a bit too blue-eyed. Question: – there are affordable OBDs that support almost everything also the EZS (e.g. iCarsoft MB II i980 or iCarsoft i980 or what from AUTEL) – would “OBD2 Shop” be a trustworthy supplier ?
