just joined the S85 Owners club with a 2006 M6, These videos will help

I've got the throttle actuator issue... It's intermittent when they start failing... Usually it will fail the start up test and go into limp mode.. No rough idle or associated codes for that one Dirty air filters tend to make mine idle higher... It settles quicker and lowers once they are clean... Tied into this is a high idle and that is for raising the catalytic temps when you're stationary which is normal... This doesn't tend to cause rough idle issues but still worth checking if you have issues and also part of regular maintenance I've had 2 coil failures and if you're gonna swap these it's worth doing a plug change while everything is off Fantastic video, start with the smaller easier stuff and definitely worth getting a scan tool to narrow down issues 👍

Rough idle from throttle body actuators comes with a slew of error codes but ultimately they are not helpful other than to indicate you need replacement of these units all together. The key to this issue is the continual surging idle at standing as it continues to hunt for an idle spot on the RPM. You can be unlucky like me and also have idle body actuator failure as well and on the other bank complicating the repair no end as you can’t diagnose which bank failure it is. Since you have to go deep to replace them (top engine dismantle of plenums and many hoses) and usually the age, it’s best to replace all four throttle body and idle actuators at once which is pricey and will cost you US$3200 in parts alone in the US. Once done you have confidence the new parts will last a long time and also being easier and faster to repair than fiddling with gears etc during a repair that may ultimately not work if the internal board has failed. There is a shop in the UK that does changeover repairs on these but if your not in the UK the time for shipping is too long to wait with the engine dismantled.

Great vids really informative, mine sometimes almost stalls when taking off normally, i have to tap the gas to take off which then ends in a very unruly clutch engagement, any ideas?

In canada our premium fuel is 91 . Husky is 94 but has ethanol added. Sucks we can't get higher octane here.

The only time I've had a rough idle, it only happened on hot starts and after I started moving the idle would smooth out the next time I came to a complete stop. I did a test and found my VANOS solenoids had low quality, after replacing those, I never had the idle issue again

Off point, where is the water valve on e60 m5?

my m5 has that problem but sometimes i just turn it off and on and the problem disappears and the mechanic can't find what the problem is

Hi mate i have horrendous fuel economy in traffic 7/8 mpg or 30L/100k however on the open road its fine gettning around 11. my s85 also stalls if left idling for more than a few minutes. it had a cylinder 4 misfire code stored but has not come back. Do you have any suggestions for fault tracing this. i suspect it may be early signs of a failing ionic unit

Can I drive it 20 miles to my shop with reduced power from a cyl 4 misfire?

Is 93 ok?
