50i - 113027 Crank no start - Blown ISM fuse
Hello Everyone,
Thanks for taking the time to read my post. I have an F15 50i that has now been to two mechanics, including a service rep from BMW service centre. I pulled out of a dealership (looking at new car) around 30% throttle sunny Australia conditions car pulled up into limp mode. Nursed it 2 kms then engine cut off would not start. Let it sit for 30minutes managed to start it and get it to a mechanic. Fault code was 113027: ignition relay and injectors, supply voltage, fuel injection short to ground. Car can start but is running very rough can coax it. Discovered the ISM had a blown fuse in it. Ordered Genuine part from BMW replaced it. Vehicle will crank but wont start. Put the old ISM back in with blown fuse and it starts (albeit rough). Checked the wiring diagram, found it belongs to cylinder 7, replaced coil/spark no change. DME ground wire was slightly burnt on attachment to car replaced this. Mechanic advised that the with the new ISM the DME sends no signal to ignition system / injectors and vehicle wont start. The old ISM with the broken fuse the signal does get sent hence the car starting. 1 year ago there was a coolant leak that had left some dried coolant (that did get cleaned) over cylinders 6 and 7. Main battery had been replaced 8 months ago. Rear fuse checked. Just wondering if anyone has any ideas at all with this. I am somewhat confused with the car starting with a broken fuse in the ISM but not with new module. Mechanic doesn't believe it to be the DME. He has also traced the loom looking for shorts or corrosion. Cheers again |

I can't believe this has been going on for 3 months. Not sure if that factory extension will work in Australia, but thank you I may give it a try. |

It should work in all regions 🔥 It is a BMW factory extension item. Don't be afraid to push the dealer a little bit. Best of luck. |

Hello All,
It was the DME it got replaced a month ago. First time giving 60-70% throttle it went back into Drivetrain Malfunction and received the below codes, 1F0515 Valvetronic Supply voltage Open Circuit 133011 Valvetronic Supply Voltage Malfunction 1F4A10 Relay Ignition and Injection, Activation Line Interruption 133104 Valvetronic Relay triggering open circuit Wondering if theres a short circuit something similiar to this guy. https://f80.bimmerpost.com/forums/sh...ghlight=1f0515 |
