BMW i8 Jump Post Location & Safe Protocol

📍 Step 1: Terminal Location

Battery & Remote Jump Posts

Under-hood remote positive (+) post under red flip cap & dedicated hex ground (-) stud on strut tower. Battery is located in the trunk floor (right rear or center well) with an IBS (Intelligent Battery Sensor) and positive Safety Battery Terminal (SBT pyrotechnic disconnect).

⚠️ Step 2: ECU & Fuse Safety

IBS & Fusible Link Protection

Never clamp directly to the trunk battery on BMW E90/F30/G20/E70/F15/G05 models—bypassing the Intelligent Battery Sensor (IBS) can corrupt the DME/BDC/FRM module or blow the rear power distribution box fusible link. Low voltage (<10.2V) frequently triggers Transmission Malfunction warnings and steering lock errors that clear once properly boosted via the under-hood posts.

⚡ Step 3: Charging Check

Alternator Voltage Test

Post-boost verification of 150A–220A Valeo / Bosch Intelligent Alternator (BSD Bus) output (13.8V–14.8V on 12V; 27.6V–28.4V on 24V commercial).
