@samcrac Hey Sam I had the same problem on my salvage i8 it took 3 flushes and the recommended bleeding procedure in the manual. For evry two minutes after the engine starts you have to rev to 3500 rpm for 5 seconds and rest for 10 then repeat that 4 times until you hit a total time of 16 minutes. Now repeat the entire thing exepect at 5500 rpm until ur total time is 18 min. Then at 18 min do it one last time to 5500 rpm then take a test drive in sport mode. After three times of doing this it solved my problem

I found this "For the bleeding of the high-temperature cooling circuit proceed in the same way as the procedure for conventional vehicles. However, unlike in the low-temperature cooling circuit, the bleeding procedure does not end automatically, but must be independently completed by a Service employee. 1 Evacuate and fill cooling system using vacuum filling device. Remove the vacuum filling device after the filling procedure is completed. 2 When the expansion tank is open, open the bleeder screw for 20 seconds. 3 Close the bleeder screw and expansion tank again. 4 Terminal 15 ON, set IHKA controls to 28 °C / 82 °F at blower speed 1 and "Air conditioning OFF". 5 Press the accelerator pedal for about 20 seconds at full load (engine OFF). 6 Start combustion engine in selector lever position "P" with Automatic Hold brake engaged. 7 Increase engine speed using accelerator pedal 4 times for about 5 to 10 seconds to roughly 3500 rpm, with a 10 second interval between the respective engine speed increases. Repeat procedure every 2 minutes for about 16 to 18 minutes. 8 Increase engine speed using accelerator pedal 4 times for about 5 to 10 seconds to roughly 5500 rpm, with a 10 second interval between the respective engine speed increases. 9 After 20 minutes carry out a test drive in selector lever position "S" and with heating turned on fully. 10 The ventilation is completed as soon as hot air flows continuously from the air outlets. 11 Adapt coolant in the cooled down state to MAX filling level" hope it helps!

Many years ago, I went through a similar problem with the Mitsubishi Starion. The thermostat kept showing that the car was running extremely hot. After exhausting all possibilities, including water pump, thermostat, and a fan clutch, to no avail, I finally realized that the only indication that the car was about to explode was the gauge, no other steam, or drainage anywhere. Several mechanics and dealerships later, I found one man that told me it could be a blown capacitor on the gauge. Indeed, it was, the car was never overheating, and a $25 replacement part finally took care of the problem.

Milky residue under the oil cap most of the time caused by short trips before the oil gets warmed up. If it's possible, check and make sure coolant is circulating and purge the air out of system.

You've probably found out how to fix the coolant problem, but I found this just in case....Great vids as usual, keep them coming.👍 Evacuate and fill cooling system using vacuum filling device. Remove the vacuum filling device after the filling procedure is completed. 2 When the expansion tank is open, open the bleeder screw for 20 seconds. 3 Close the bleeder screw and expansion tank again. 4 Terminal 15 ON, set IHKA controls to 28 °C / 82 °F at blower speed 1 and "Air conditioning OFF". 5 Press the accelerator pedal for about 20 seconds at full load (engine OFF). 6 Start combustion engine in selector lever position "P" with Automatic Hold brake engaged. 7 Increase engine speed using accelerator pedal 4 times for about 5 to 10 seconds to roughly 3500 rpm, with a 10 second interval between the respective engine speed increases. Repeat procedure every 2 minutes for about 16 to 18 minutes. 8 Increase engine speed using accelerator pedal 4 times for about 5 to 10 seconds to roughly 5500 rpm, with a 10 second interval between the respective engine speed increases. 9 After 20 minutes carry out a test drive in selector lever position "S" and with heating turned on fully. 10 The ventilation is completed as soon as hot air flows continuously from the air outlets. 11 Adapt coolant in the cooled down state to MAX filling level.

[@ProjectsbyTMD]

With your comment on no coolant circulation and eliminating the thermostat as a possible root cause, one possible suspect is that there may be a sand casting core that has broken loose in the engine and blocked one of the coolant passage ways. (The casting core when the engine block/head was manufactured.) Pressurizing the inlet side and the alternate pressurizing the outlet side of the 2 hoses going to the radiator with air might help to confirm this possible diagnosis.

[@Motorheadco]

Now that’s how you do an ad 😂

Sam, the I8's thermostat works by using a plunger with some special wax to ensure a seal when it is closed and a signal from the ECM. Perhaps a pin in the ECU is dead or some wiring is chafing. Or the thermostat has a broken part inside

Yes, maybe you're right but I also work with those scopes at the dealership and when they sit for some time, the date Display is often very off! Same thing with Dashcams. But you're probably right though 😅

This is gonna be interesting. BMW and McLaren dealership techs couldn’t fix the overheating issue. My man Sam thinks he could resolve this issue?

[@billigerfusel]

That's the confidence you need to pull shit off.

[@ericl452]

Working on it in the field! A literal shade tree mechanic fixing the i8 when the $150 per hour dealership techs can't (or won't put out the effort to). On a side note, I think you are on the right track. I suspect voids in the cooling system, a stuck thermostat, or pieces of broken water pump blade restricting a coolant passage (happens occasionally on the early water cooled 911 engines with plastic water pump impellers).

[@matte8441]

Some dealership mechanics are lazy and don’t know what they’re doing anyways. I work at a dealership and train most of the newcomers. Literally just two people impressed me out of the dozens that had to shadow me. Then you have the lazy ones who can’t bother to diag properly or dislike certain big jobs which is probably the case for this i8. I worked at a Toyota store and we literally had techs file for vacation if they knew they had to deal with a hybrid powertrain issue or if they had to do the Tacoma frame replacement recall.

[@dangerouskoin4874]

Often if it requires removing the engine, they wont work on it. Since no one was under warranty for this, to hell with that they said. They wouldn't make any money selling it after repairs are done. That's why. Not because they couldn't fix it. They didn't WANT to.

[@izalman]

Car Wizard or Diagnose Dan... both would have it sorted cos they are old skool mechanics who understand how to sort modern crap

[@pdlegend6829]

Is it ACTUALLY overheating? Get a separate temp gauge on it...

[@andyb6851]

Yeah, I'm also surprised they didn't use tools like a temperature gun to check things, especially if the whole radiator is hot.

[@fairysox221]

Did you miss the part about water not circulating ?

[@Foxxtalejr]

That sounds like a coolant line blockage more than a thermostat issue. The thermostat has almost certainly been replaced (jumper it or remove and/or replace to see what happens but probably not the issue). I'd take a look at where your temp sensor is complaining and check the flow around that area. Hopefully it's not a blockage in the engine block...

[@cheesestick8024]

Yeah right. The dealer couldn’t fix it, but Sam came to the rescue. 👌

[@horvath14041984]

I had a similar problem. There is actually an airbleed screw in one of the coolant lines. Mine had an every so slight leak in it. Air would build up and coolant couldn’t flow past it and engine heat up. All BMW need the coolant system vacuum pulled but air was leaking back in through the bleed screw. This means you have to bleed it prior to vacuum pulling it. The air trapped in it will prevent it from circulating.

@Daniel Smith shut up

[@gradoisx2348]

Most modern cars that type will have a coolant temp sensor on the engine itself and on the radiator to check cooling system efficiency. Make sure to check both sensors

[@chrisgreenfield1061]

Here is how to bleed the cooling system on the i8 i really hope this helps fix the issue sam For the bleeding of the high-temperature cooling circuit proceed in the same way as the procedure for conventional vehicles. However, unlike in the low-temperature cooling circuit, the bleeding procedure does not end automatically, but must be independently completed by a Service employee. 1 Evacuate and fill cooling system using vacuum filling device. Remove the vacuum filling device after the filling procedure is completed. 2 When the expansion tank is open, open the bleeder screw for 20 seconds. 3 Close the bleeder screw and expansion tank again. 4 Terminal 15 ON, set IHKA controls to 28 °C / 82 °F at blower speed 1 and "Air conditioning OFF". 5 Press the accelerator pedal for about 20 seconds at full load (engine OFF). 6 Start combustion engine in selector lever position "P" with Automatic Hold brake engaged. 7 Increase engine speed using accelerator pedal 4 times for about 5 to 10 seconds to roughly 3500 rpm, with a 10 second interval between the respective engine speed increases. Repeat procedure every 2 minutes for about 16 to 18 minutes. 8 Increase engine speed using accelerator pedal 4 times for about 5 to 10 seconds to roughly 5500 rpm, with a 10 second interval between the respective engine speed increases. 9 After 20 minutes carry out a test drive in selector lever position "S" and with heating turned on fully. 10 The ventilation is completed as soon as hot air flows continuously from the air outlets. 11 Adapt coolant in the cooled down state to MAX filling level.

[@zombieslayer621]

Not saying anything but I work at a dealer. And your issue is probably a hard line from the engine to the front of the car. It’s about the size of 14an maybe a inch thick or so. It leaks on a tiny crack on a mounting bracket near the right rear wheel next to the battery pack. It will only leak the hot fluid and it evaporators quickly and you can only see it if you pull the panels. The reason there is no flow cause how that system is set up it needs to be under complete pressure through the entire system.

[@suggesttwo]

Thermostat, rad, water pump. Checking for head gasket : does it holds pressure? Warm it up squeeze a radiator hose.

[@supertouring1]

I REALLY wonder how that would have turned out. Lawsuite? Did the dealership guarantee the engine replacement would solve the problem? Or did they just suggest the engine replacement knowing full well the owner would not do it? And did they manage to convince the owner to lease a new 2002 BMW I8 to replace this one?? So many What ifs... :D

man I'm lucky to be in south australia, because we don't need coolant. Just anti corrosive resistant cooling fluid, because cars these days don't overheat, and it doesn't really get to freezing here
