Passat B6 steering lock with ELMOS

[Griunvaldas]

Hello I have Passat B6 2006, 2.0. If I put key there's no lights on dash, no terminal 15 (ignition), nothing. Then I bought exactly same second hand ELV (same HW and SW). Plug in the car - ignition ON. Thought of easy repair... replaced ELMOS processor, microswitches - no ignition again. Tried replacing with new uswitches - no ignition again. Any ideas what else can be done?

relay 460 faulty?

Conv. control module (also known as comfort module) seems faulty. It's number is 3C0 959 433 R. Bought second handed conv. module that ends with H. Ignition ON, +12V to ELV (steering lock module), keys recognized (Engine start NO, key AUTH NO, transponder key YES and so on....). Got my hands on another ECU kit with EXACTLY SAME ALL numbers (ECU + key + ELV + comfort module). And what do you think? Another with R letter, and another same problem! Anyone can confirm failing R letter modules? I suppose it's SW error, because if I force ELV switch, diagnosing IMMO system I see comfort module number, just always error no communication between ELV and conv. control....And of course of statuses of KEYS are NO/0

Found the problem - damaged eeprom. Can anyone check for any error, checksum fault? Anyone?

no solution, buy new one steering lock and adapt it and works.. or you can buy from scrap and try change parts inside, sometimes it helps
