[juniormaxxx]

car came with lot of errors in engine ecu..delete them all and drive day/two too see what will be new erorrs..exchange 1 lanbda.ckp and cmp sensor..now engine work perfectly ...but there is one trouble why actualy came to me..sometime car wont start..starter work but will not start..in that time IF I leave ignition on I can here strange sounds from engine and behind glove compartment some relays clicking..pointer of tacho goes straight to 7000 0/min and back to zero..in this time engine wont start..starter always work...so this is ews from bmw if starter work then keys/ews/ecu are syncronized or I mised something...I have few days to solve this so help me to learn homework on bemers..

Has this had a flat battery or a new one? Make sure battery is 100% charged. Lower drivers window. Disconnect battery for 15mins. Then try again. Scan for fault codes and see what comes up.

today I used this bemer as cofee car..so few times on cofee in total 50km..not a single fault...I manage to find somewhere that this type of ews have 2 immo related system..first is block starter motor and second use rolling code to enable engine ecu to start,I will use it next few day to see what is new on eror code list



autoden -batery is fine..I already try this few tricks but germans have some resistance on tricks..


I give up car to customer..there is no or litle petrol in tank..so how the hell I can test it next few weeks??
yust for precautions I soldered all conector on engine ecu ..only few pads look suspicious but when tool is hot who care solder them all..will wait for response..
until then
SOLVED
