    Model Y, unusual noise from dashboard area, recording attached

    If the sound comes from speakers then it could have been produced by the MCU due to EM interference. This has affected a number of model S and X (both MCU1 & 2) and is fixed by adding a few ferrite clamps, might not apply to your case but it's worth locating the source of the sound.

    Model S 2021 excessive idle battery drain

    My Model S consumes 160-200W when powered on. Suppose that it does not go to sleep then it'd consume 3.8-4.8kWh/day, which is 5-7% total battery capacity. The easiest way to check whether the car goes to sleep is to use a monitoring service like TeslaFi (free but it has a 30 day trial) or...

    Model S 2017 75D wont sleep properly 1hr sleep, 15min awake repeat...

    I was going with a total capacity of 90kWh, but for 80kWh the power consumption is 0.02 * 80000 / 24 = 66.67W which could add up over the course of a year (584kWh or ~2000 miles..). If my car is awake for an extended period then it's always due to Sentry Mode keeping it awake. Looking at a...

    Model S 2017 75D wont sleep properly 1hr sleep, 15min awake repeat...

    That seems typical for Model S with MCU 2 upgrade. The graph seems to show activities on an hourly basis, which does not necessarily mean that the car doesn't sleep, just that it wakes up at least once at hour. 2% per day for your battery seems a little high (75W standby consumption), but the...

    Model S 2017 75D wont sleep properly 1hr sleep, 15min awake repeat...

    It shouldn't have consumed that much energy on standby unless you have things like Sentry Mode/Cabin Overheat Protection turned on. Other cars don't have these features so a fair comparison could be made only without them enabled. As an example, here is my standby graph from yesterday. It lost...

    Model S 2017 75D wont sleep properly 1hr sleep, 15min awake repeat...

    The degradation is at its worst at high temperature and high rate of discharge. With this type of drain the effect would be negligible. I don't have a directly relevant study to the effect of low-C discharge on battery degradation, but we could gleam some information from...

    Model S 2017 75D wont sleep properly 1hr sleep, 15min awake repeat...

    I'd expect that most of us would have access to cheap night rates, the 20 quid figure assumes a 7.5p/kWh night rate, but I take your point that everyone's circumstance might differ. It's quite a bit higher than an average ICE's energy consumption on standby, which seems to be 1-1.5W.

    The vampire drain averages 30W (16-20W for a more modern Model 3/Y as they can sleep for longer), over a year it'd cost ~20 quid. This doesn't seem worth concerning ourselves over.

    Recell: certified replacement battery packs for low-range/bricked Model S

    @wk057 Have been waiting for your feedback on this and you didn't disappoint. Many thanks for the detailed information. We don't even have any comparable after-warranty service here in the UK, but in the next few years as more garages open up to fixing Teslas/EV in general it'll be crucial to...

    possible first time long distance + wrong side of the road. Tips? Mad?

    It sounds like you're using country-specific charge cards then?. For us it'd be a little tricky since we tend to travel without a specific destination in mind so our plan could change often. It's a pity these charge cards aren't available from a grocery store.

    possible first time long distance + wrong side of the road. Tips? Mad?

    I expected the price to have been set by the charge point but as long as the price quoted is clear, I'm okay with it. There are some charge points around Europe that are acceptable prise-wise (22kW, 0.33EUR/kWh). Many are 0.59EUR/kWh though and PlugSurfing doesn't make it clear how much they're...

    possible first time long distance + wrong side of the road. Tips? Mad?

    I've just done a 10-day trip to Europe (France, Belgium, Netherlands and Luxembourgh) this Easter holiday, 1700 miles roundtrip. Other people have touched on most of the things to be aware of but here are a few more related to charging: - Buy charging cards to be able to use them at non-Tesla...

    Semi-new 22 LR owner questions

    I noticed a few things: 1) The time your car spent before going back to sleep appears to be longer than mine, which is most typically 16 minutes. Here's mine for comparison: TeslaMate shall keep the car awake for at least 3 minutes before stopping polling and allowing the car to go to sleep...

    Semi-new 22 LR owner questions

    The percentage could be less on the S/X compared to the 3, but the miles loss figure might not since they are based on the EPA, which depends on both the driving efficiency and the battery capacity: having a larger battery does not necessarily translate to more range, so quoting the range...

    Semi-new 22 LR owner questions

    He used TeslaMate so wouldn't need an OBD device for the info. Thanks for the link. It looks like the Model S might consume more power during sleeping than the 3 & Y, but it could be misleading since the 3 & Y are generally more efficient during driving. I'd expect that the power consumption of...
