If you have a persistent misfire that appears after car is warm (after 5 mins). This is an easier fix than coils and spark plugs but more expensive. Just remove top air box for room but if you have better tools you can just remove it directly. It’s just 4 bolts per unit per side. Easy to diagnose, swap units, run car for 5 minutes if misfire cylinders just swaps it’s likely the ionic current control unit. Just be careful with the wire harness and plug. Coils and plugs near the firewalls from what I know is tricky, I got Jon to replace all 10 when 1 of them misfired. Get a real mechanic like Jon; I am an armchair mechanic, with a sprained finger and a daughter that cares about not straining my finger further 😇

I guess M5 ownership means something has to happen every year. Got a misfire a few weeks ago, I just thought hmmm this is odd just got 10 new coils and 10 new spark plugs less than 10k kms. Anyway, I read a little and I found a good potential culprit... Ionic Current Control unit. Fancy pants distributor that BMW experimented on the S85. I thought it doesn't seem to be hard to diagnose so I gave it a try. Swap the left and right unit around, sure enough the misfire just went from cylinder 8 to 3. The part wasn't cheap, but to reach it was relatively easy. Just remove the airbox, it's cover and wire harness. My daughter helped me a bit, as I have a finger injury. We discussed it a bit, why I think my theory is correct and just order the part. Ordered from FCP Euro with a kind discount from the CEO, about a week after it arrived along with some other parts. Today my daughter helped me again, my finger is taking ages to heal. Top part is the new one, bottom is the broken one. The other working seems to have been replaced as well by previous owner. I may order another one eventually, ordering 2 will definitely attract customs. Test driven the car, that sorted out the misfire which will appear when car in on temp. I hope the rest of the year will be boring...

Spotted an AMG BMW 🤣

Finally fixed my electrical issues: abs, dsc, smg, trunk not opening, key, lights, etc... the culprit is an ABS front wheel sensor. Its seems the original is shorter as per Aaron at A1 auto electrical caused all the chaos, shipped 2 new ABS wheel speed sensors to replace it. Errors are gone, after it being persistent in the last few weeks instead of being intermittent over a year. Revised part number is 34-52-7-853-583 about $145 USD each for original BMW. Local dealer is around $500 NZD each. I still have the old pair if anybody wants it but will throw them away eventually.

Saw a couple of Z3, Z4 and M2 yesterday at Heritage Park

Minor update, ever since taking that longer road trip to Mangatainoka the diff chatter is significantly better. I guess it only needed a real long drive to get diff oil in. So far no electrical panic since changing the IBS as well, only discharge warning when it had to be left while we where out of town. I had never had this warning, so likely that old IBS is really busted. Aaron also couldn’t get any data out of past 2 days. I also just changed the wipers, so far 2023 has been a boring year… knock on wood 😅 Got also parts accumulating in the shelves and to do items. 10 injectors, fuel pump, thermostat, throttle body actuator gears, etc. I am looking to change our keys, the battery is probably super low now. I know you can replace the battery by soldering, but I might buy an aftermarket key and code that in case I break the original keys.

Looks like MAHLE is making improved bearings. Probably worth looking at, hopefully not a marketing deal.

Jun started following M5 E60 does a lap on Nurburgring, e60 m5, M5 drag race E28, E34, E39, E60, F10, F90 and and 1 other

No real hard data on this, Jon did ours after he did Pete’s car. Ours was 61k kms, insurance paid most of it (long story). I have only added 7k kms for 2 years. At this rate I will be too old before the next rod bearings. I think just do it in your ownership if you plan to keep it, as well as other items. It’s kinda part of the ownership as i would take it.

So the E60 M5 is a reliable car?!? 🤣 Although likely need a clutch at 10,000 miles with the launches it did. BMW M5 Generations DRAG RACE - YouTube

If you need the clutch centering tool, I have one. I had to buy one as Jon didn’t have one when we did our flywheel and clutch.
-
The expression on the owner throughout the video is priceless. I think I know how I would look like when Misha drives our car. Also ridiculous if you look at the fuel gauge when it starts and what if left after the lap. So I think the M5 can only do 4 laps at that rate 🤣

Yes agree, but I do keep it idle for 1-2 mins. I don’t really wait for the temp to go up, I don’t drive immediately on the first start to check everything is working and no funny sounds. I think the to warm to temp and not to warm is a bit pedantic, no real study either way. Since modern cars with ECU adjusts its timing, etc the engineers have designed it to be driven. I do drive it as no real point in wasting petrol, but the thermostat and engine is surprisingly efficient. Only monitored this after the expansion tank burst, seems to be within temp of 79c in 5-10 mins only. To keep the rpm low while driving got this tip from M Tech guy, Christchurch based YouTuber. An easy way to keep the car at low rpm, is just put it in auto as M5 auto always reset to shift 1. This means it goes up the gear, hardly touches 2k rpm if driven normally. Surprisingly less cumbersome than shifting early in manual.

Looking at your fixed ownership history, I believe the crystal ball is telling me that you will be buying not just 1 but 2 E60 M5 soon! (chatGPT/Bing Chat) does seem to agree with me:

I think you are a bit generous. 2.5km/l is about 40liters/100km (or 5.88 mpg) that is 2x worse than 5.5km/liter. I hardly use the M5 in town, the SMG is super crap in slow traffic. We have to look at the positive side, I have racked about $7,000 in AA fuel points in the last few years. Now that we sold the Cayenne and Skyline, the M5 is still raking up fuel points even with minimal usage. All those points are being converted to ChargeNet credits which don’t expire, unlike AA Fuel points is just 30 days. I can’t even fully use all the credits, ChargeNet owes me about $100 of electricity and it keeps on gong up…. 😅

I don’t know your full ownership history, but here is what I know. Your ownership history: E31, E60 M5, E36 M3, E61 (current car), looking for E60 M5… I think you will get a E36 M3 in the next 5 years. You need to seek some professional help 🤣 or you can save that money and stop selling your cars.
