I am hoping for some advise on a 1993 318i with the 1.8L (M42)
Months ago I replaced the plastic coolant fitting underneath the intake and ALL went well BUT now this same car keeps flashing trouble code #1223 and illuminates the "check engine" light
I have access to AllDataPro and when through all the diagnostics including replaceing the computers tempurature sensor. I have tried removing the fuses and unplugging the DME to erase the code but it always comes back.
I only have domestic software for my scan tool but is there a secret to eraseing codes without a scan tool ? I though about removing the battery ground but I dont have the radio code.
The car does have drivability issues when cold so I am wanting to fix it but shudder at the thought of dealship intervention
I am definately a BMW NOOB
so any advise would be great
