Fixing a bmw part 2. Diagnosing water pump+ replacement. + New scan tool. OTOFIX D1.

Hey viewers, Lance Mechanics here — and welcome back to Part 2 of the BMW 328i project. It’s late, I’m on my 7-on / 7-off shift, and this is one of those “fix it when you can” videos. Today we’re diving into the infamous BMW E90 electric water pump, CAN bus issues, and putting the new Autel/Autofix D1 Lite through a real-world mechanic test, not a studio review. Instead of a dedicated review video, I wanted to show the tool actually being used in a real diagnostic situation: crawling under the car, unplugging connectors, actuating pumps, and doing live bidirectional testing. 10% off Promo code for your fans: LANCE888 LINK to amazon: https://www.amazon.ca/dp/B0DK7K7QFG?maas=maas_adg_6CCE4F637200EFB2EDE9BC05F8832CC3_afap_abs&ref_=aa_maas&tag=maas&th=1 🔧 What We Did in This Video Jacked up the 2010 BMW 328i xDrive Removed skid plates and under-tray hardware (Northern Ontario bolts actually came out!) Inspected the leaking crank sensor from previous owner Diagnosed CAN bus faults: Electronic coolant pump missing IBS/battery sensor codes Alternator BSD signal missing (2E98) Used the Autel Autofix D1 Lite to: Auto-identify the E90 Actuate the electric water pump (50% / 95% / 100%) Run live data Clear old codes Perform service resets (transmission adaptations + oil service data) Test battery functions Discovered the water pump was pulling down the network Installed a new pump (Amazon special… we’ll see how long it lasts) Narrowed remaining fault down to a BSD alternator/battery signal issue Added a few 1AM mechanic ramblings for good measure Accidentally reviewed a scan tool by fixing my BMW 😂 🛠️ Thoughts on the Autel Autofix D1 Lite (Real Mechanic Use) This isn’t a paid promo — I decided to use the tool in real time so you can see how it performs when things aren’t perfect: ✔ Instant auto-detect once powered ✔ Thin, compact, really nice screen ✔ Same OS as Autel (because, let’s be real… it is Autel) ✔ Bidirectional tests work perfectly ✔ Wireless VCI with OBD-port light makes life easier ✔ Fast on BMW modules ✔ Service resets and adaptations actually work ✔ Great tool for driveway mechanics and techs needing something portable If you want a full dedicated review, let me know — but honestly, I think this “real job review” format is better. 🔥 The BMW Project Continues… I still need to track down the BSD alternator signal fault (2E98). The battery voltage reading is suspicious, and I suspect either: bad IBS sensor wiring alternator BSD line issue corroded connector weak battery throwing off the readings We’ll dig into that in Part 3. 👨‍🔧 Why I’m Doing It This Way I prefer showing tools and repairs in the real world: No perfect lighting No staged failures No scripts Just me, a broken BMW, and tools that actually get used If you’re a DIYer, a tech, or someone who likes watching mechanics fight cars in their garages at 1AM… this series is for you. 👍 Support the Channel If you enjoy the content, hit like, comment, and subscribe — it helps more than you know.
