Any suggestions as to what this could be? I had to change my coil pack as the car started misfiring and had erratic idle out of nowhere. The side of the coil pack on number 3 was slightly melted. I changed the pack and the HT leads and plugs but no joy. Number 3 isn't sparking. I checked it off the block. I even tried disconnecting battery and ecu to see if it needed to be reset but still no joy!

It's a 1998 e36 318i. Any advice appreciated. A mate in work reckons I've to get new ecu and another lad said maybe a sensor in the crankshaft

If you replace the coil-pack, did you reset the computer codes... Or even try disconnecting the battery for 1hr+...

Nope don't have the gear to reset codes. I disconnected the negative for 30 mins. That not long enough? Should I disconnect it completely ?

      BMW 318i boot locked can’t get into

      Update: I checked my battery and it charged in 5 minutes, so I don't have to find another alternator. All seems to be OK except for the plastic "L"s with a short rubber hose that bypass the HV/AC solenoid. Those get clogged after @ 150,000-190,000 miles (if distilled water wasn't used) and cause air pockets that try to burst radiators. I have a few more brass "L"s, so now I can throw the plastic ones away. I have to be careful I don't fog the windows though, without heat or cool.

      105C thermostat replacement

      You are absolutely right. The strange thing is that when I put the chassis number on the realoem it shows that the temp sensor is not applicable on my vehicle. I will physically check for a sensor. In the meantime, do you think that the removal of the MAP activated thermostat will effect the temp gauge on the dial instrument item 6? I am tempted to add a dummy resistor , 11.5ohms - 13watts , to simulate the MAP thermostat. Your thoughts?

      SLIPPING CLUTCH

      Morning Andrew I normally disconnect the Neg lead only, some folks disconnect both a few even say disconnect both and touch them together. Goes without saying both sensor plugs need to be checked and a squirt of contact cleaner applied never hurts 😅 Dave

      SLIPPING CLUTCH

      Hi Dave, I fitted one of the sensors on the rear but it has made no effect as the light is still there, I will fit the other sensor tomorrow and see how it goes then. You mention the disconnect the battery, is there any pattern to this ? is it both leads or just the negative lead? cheers Paneuro.
