Hi good people!
I have Z3 1.9 87kW, '98 without alarm and without central locking.. I own it for one year and it never had issues with engine. Last monday I stared my Z, and then after few meters rpm felt down for one second, nearly stopped engine and then it went back. It happened once again after next hundred meters and then I went 10km to my job, with no failures, hesitation, performance problems, etc. But after one hour staying, I tried to start it again and it was only cranking. No unusual warnings on dashboard, only cranking. Tried fuel prssure in rails - yes there was pressure. Then checked all fuses, relays, also that ones under steering wheel, I hear fuelpump when turning key. I followed some yt videos and found that maybe crankschaft sensor can be problem. I changed it for new one- still the same... So it went to garage. Today my mechanic tried some old delphi diagnostics on it, because his new one showed no errors. And he found some "144Error code", which says immobiliser failure. He also found there is no sparking. He also tried new set of coil and spark cables... Fuelpump, fuelfilter are ok, battery is ok,... Now he left the car as it is because he is not electrician.
Do you guess where can be problem?
I realised that few days ago I locked my keys inside car and needed to use grey key. Maybe I mixed them somehow and used grey one for starting...I dont know. I'm getting lost a bit.
Thanks for any advice!
