MB Kildare Irl gave me printouts from HHT i just wondered is that a STAR machine ? WIS seems to talk about two diff things. :dk:

Also under a section marked AGN it has fault codes like P2001 Pressure regulator ED3. Are the fault codes relating to the gearbox or are they just general codes. But when i look up the code it says P2001 is NOx ....O2 senor or DPT. I will try scan the pages tomorrow. If the code is generic then why is it under the AGN heading ? And why do MB say no gearbox faults found when there are five listed under AGN or am i being silly ??

HHT is the very old Hand Held Tester for old MB models. Your workshop must have been using the current Star diagnosis tool that has a simulated version of HHT, HHTWIN.
