Hey everyone, I have a “healthy” MCU1 with the replaced eMMC and a new screen replaced under warranty. I do not experience crashes, and I don’t use the FM/AM/XM radio My only complaints are the slow nav/audio load times, and slow boot times when the car has been sitting a couple days. I’m...

Hey folks, Randomly last week, I came out in the morning and noticed that the driver side front and rear air struts had dropped down an inch overnight. Immediately when I got in the car, the compressor kicked on and refilled them to the proper height. They leaked out again the following...

Hi Folks, I recently purchased a 410mm Big Brake Kit for my 2016.5 Model S P90D from RB Racing Brake in the UK. Why, you might ask? Because it looks sweet compared to the baby brakes that come OEM (front brakes on the S are the same as the rear brakes on the Cadillac CTS-V :confused:), and I...

Hey folks, I was gifted an "Introduction to Performance Driving" course at COTA in Austin. I used to do HPDEs back when I had my 911 - I'm comfortable at track speed, and I'm very excited for the event.......however I have seen lots of posts about "legacy" S's having heat issues from the...

Hello everyone, I have always thought the brake pedal on the S was a little soft-feeling. I was working on stainless lines and re-bleeding, but since this is electronic, I realize that may not have any direct impact on the pedal. I read on Bosch’s website that the iBooster is adjustable...

Peculiar Issue. Over the weekend, I swapped my brake pads and rotors. I also removed a broken dash cam and installed a new dash cam (front and rear camera). When I got back into my car, my TPMS light was blinking, and I didn't get ANY TPMS values. I don't mean they showed the "- -" like it...

Hey folks, I have never really liked the pedal feel on my P90D. The brakes work fine, but the pedal travel before it gets really heavy on the brakes is a more than it was in previous performance cars. It also never really gets “firm” like on my old M5….the real road feel isn’t there. I always...

The other day, I made a thread about prepping a Pre-Refresh Model S for road course racing. turns out, it's a no-go. Mainly because of brake fade and thermal limiting on the battery. Thing is, AutoX is only done in 60 second bursts....Could I squeeze that in before the BMS gets angry?? I...

Hi folks, Last year when my son was born, I had to sell my beloved E46 M3 track car. Given that all I have now is my 2016.5 P90D, that pretty much killed my track days. Last weekend I got the chance to run a 911 GT3 RS around a local track for a few hours, and it made me remember how much I...

Hey Folks, My 2016.5 P90D has 72a charging, and I have a Gen 1 wall charger that can support it. What I've noticed, though, is that if I charge at 72a, the fans run full tilt, the charge cable gets "hey that kinda hurts" hot, and my whole garage gets pretty warm. If I bump it down to 50a...

I need to have my car re-leveled, and the SC will only do it with factory relight height sensor links on it. I have lowering links, and lost my factory ones during a move. Does anyone have a spare set of factory ones around I can buy? Ideally the black plastic ones, not the metal/green ones.

Hi folks, I am in the process of refreshing my front suspension and purchased the OEM Tesla replacements and the Sidem to compare them. NOTE: Beck Arnley resells the Sidem parts, but in a blue BA box. It even has the Sidem stampings on it. So, you can save some reseller markup by buying the...

Hi everyone, As of yesterday, my alignment was set perfect. Steering wheel was perfectly centered, only a very minor drift to the right as you'd expect from crowned roads. Today, I did some spirited driving on some twisty roads. When I got back on the freeway, I noticed my steering wheel now...

In a Gruber video from last year, they mention that Tesla doesn't advise buying a 100kwh pack and putting it in a P90D as an upgrade. Tesla cites the reason as being related to impacts in the "airbag deployment timing and structural rigidity" of the car. Not a firmware issue. I don't really...

Hi Folks, Last year, Tesla replaced my steering rack under warranty. To do that, they had to drop the front subframe. I've had trouble getting the car aligned since then - it seems to have a consistent pull to the left. My most recent alignment shows the camber is good, and the caster is...

Saw a new 2022 with the updated projector headlights and taillights - thought I'd share for those that haven't seen them. Frankly, I think the new headlights look much better in person than I expected - I'm a fan. Tail lights look fine too.

Hi everyone, My 2016.5 S is pulling to the left despite a perfect alignment readout and an inspection of the suspension components confirming that all bushings are in good shape. If I hold the steering wheel to the right a few degrees, I can keep it straight. The pull gets worse under...

Hi everyone, Today I installed Unplugged Performance HP Shocks for 2012-2021 Model S. There is a general installation guide, but it's written for a 2012-2016 S, and there are a few steps missing for the 2016+ non-raven models that I wanted to cover for anyone else doing this upgrade. This...

Hey everyone, I have a 2016 Model S with AP1 and MCU1. I recently had my instrument cluster screen replaced under warranty, and now my other screen is bubbling too, so I'm considering an upgrade to MCU2. I don't have any real issues with MCU1, it's still much better than my wife's Volvo, but...

Hello everyone, I have lowering links on my car, and like to keep a set of the factory links around just in case. I lost mine in a recent move, and am looking for replacements. If you lowered your car and no longer need your OEM ride height links (not the sensor, just the link), I'd like to...

Hi everyone, I can't seem to find a database of Tesla's fault codes and descriptions anywhere online. I have the service manual thanks to emanualsonline.com (since it's no longer on fixyourtesla.com), but on my other cars I'm used to being able to plug in an OBDII reader, grab the P code, and...

The Model S has been functionally similar from 2012-2021. Therefore, all of the technical, diagnostic, and troubleshooting posts in the Model S Subforum were basically applicable to everyone. With the re-design and Plaid release, the vehicles are now substantially different mechanically...

Hey folks, A week or so back, I posted the video below with a sound I'm hearing from the front end of my P90D. Since then, here's what I've found out: 1) It's coming from both sides, independent of each other. 2) It's actually not the suspension - all components are in good shape and...

I have lowering links on my car, and my local SC won’t touch the air suspension until I put factory links back on. Fair enough, but my factory links got lost when I moved a few months back. So, if anyone has lowered their car and now has factory ones laying around, I’m interested in buying them.

Hi folks, I have a clunking noise coming from my front driver side when going over rough roads (not 'smooth changes' like speed bumps). I have checked the usual suspects: Sway Bar end Links - replaced with new Fore Arms - checked bolts, checked bushings with crow bar Aft Arms - checked...

This is the weirdest thing. My local Tesla Facebook group used to have a pretty wide range of topics being discussed from modifications to charging infrastructure to track days, etc. Now with the "FSD Beta," the only thing people talk about is getting their score to 100. Now, folks with...

Hi Folks, A few weeks back, I installed a 4 trumpet air horn on my Model S. Why? Because the factory horn doesn't seem to be loud enough to get folks' attention when they are about to cause an accident.....and this has definitely solved that dilema. I've received a bunch of PMs about it, so...

Hi everyone, I'm trying to diagnose a noise that's driving me nuts. It seems to be coming from something in the front left wheel well of my P90D. Here's a sample of the noise: The noise sounds like a metallic rattle/scrape (I thought it was the air strut at first). It is heard when going...

Hey folks, One of my air struts has noisy valves that I can hear with the windows down, and it drives me nuts. The strut functions fine, but just makes a lot of loud "pfft" air noises over bumps....so I bought a replacement strut to swap in. (I'm aware this is normal, but this particular...

Hey folks, It was a nice day yesterday, so I drove with my windows down for the first time in forever. I noticed that with the windows down I hear a very noticeable air compression sound when going over bumps, only from my front left area. (had wife drive to confirm, no noise from other...

Hey folks, Lately, I've had an increasing number of instances where my GPS position tracks in the wrong direction. What I mean is - if I'm driving down the freeway, it shows me blazing through the neighborhood 1/2 mile north at 70 mph. It will eventually reset, until it does, I can't use...

Hey folks, Over the last week or so, I've noticed that my air compressor comes on every time I turn the car on after it's been sitting overnight. Obviously there's a leak somewhere. The air shocks maintain pressure, and the car doesn't drop in height - so I'm curious if the leak is between...

My 2016 P90D was just at the SC for a steering rack replacement, they performed an alignment as part of the service. The steering wheel is now about 5 degrees off-center to the right when driving straight, and it drifts to the left on its own. More alarming, though, It now pulls to the left...

Hi everyone, I recently had my Model S over at the Service Center for some creaking in the front end when I turned the steering wheel. The SC replaced my whole steering rack, and the creaking noise went away. A week later, I started hearing an even more alarming cracking/popping noise when...

I feel like I’m taking crazy pills, but hear me out: I have Vossen 21x10.5 wheels on my car. I’ve been seeking the perfect stance. Therefore, I recently got an alignment and set my rear camber identical on both sides. Here’s the weird thing: with the camber angle is exactly -1.24 on both...

Hi folks, I am moving to a new home in a couple weeks, and am trying to validate whether the plan below is financially viable. There are several energy plans in my area for "Free Nights and Weekends" where you only pay the TDU charges. I don't get enough regular sun to use solar - but would...

For sale is my set of Lowering Brackets for any Model S with Air Suspension. Easy to install, lowers your car to the perfect height the first time, without having to fiddle with lowering links. Used, in excellent shape in original box. $390 + Shipping. Sports Air Suspension Lowering Kit for...

Hello Folks, I'm selling my current wheels - 22" Vossen VFS1 to a friend, and am thus in the market for some new wheels. I'd like to go with 21s this time, and need some insights on what to move to. My main two contenders are Brixton RF10's (have a great deal from a local dealer), and I am...

Tug, Kick, Hammer, and Ship!

I'm confused. My P90D is showing up with 79 kWh (down from 80 a month ago) in the Tesla Remote app. I was expecting that number to be closer to 90, not 12% lower. Does that figure have any meaning? Does that mean I'm seeing 12% degredation in 37,000 miles?

Hi Folks, I have 22's on my S. Currently have 245/30/22 and 295/25/22 tires on it, but am considering moving to 285/30/22 in the rear to give a bit more "sidewall meat" to insulate against bumps. My question is - that will give me a 5% difference in tire diameter front-to-rear. On some AWD...

Hi Everyone, I have my work address stored in my car, and the first time I enter the car in the morning, it automatically sets the route to my office. I rarely go straight to the office, so I want to stop that. How do I stop it from auto-routing to the office first thing in the morning?

Hi Folks, My 2016.5 MCU1 car is starting to show early signs of MCU failure. The screen randomly stays black for up to 5 minutes at startup (even though it's on 'always connected') The control menu is glitchy and sometimes does not load images/buttons Maps take a long time to load, and...

Hey everyone, Lately, I've noticed my AP1 P90D has been wandering a bit in its lane with AutoPilot engaged. I just had an alignment performed by a local shop last week to see if that was the issue, but it doesn't seem to have made a difference. The results of the alignment were 0.5 deg toe-in...

Update: The SB mentioned is not active anymore, so the post is misleading, the car has been otherwise repaired. Hey folks, I'm taking my 2016 P90D in for SB-17-31-001. This involves replacing the front lower control arms due to cracked bushings caused by a bad manufacturing batch. I noticed...

Hey All, My Model S has that annoying front air suspension noise that so many have complained about at low speeds. Below about 30 mph, it sounds like something's loose Tesla had a service bulletin that was supposed to fix it by replacing the front air struts, but it just returns after a...

Folks, Does anyone have any pictures of a Model S running on 22" Turbines from the Model X? I found a great deal on some refinished 22" Turbines from the X, and am trying to see how they fit on the S. The fitment seems fine, with 35mm offset front and rear. With a 245/30/22 in the front...

Hello Folks, I recently purchased a set of Vossen 22" wheels for my Model S, and the vendor also sold me Pirelli Pzero Nero GT tires with them as a package. The tires are 245/30/22 (F) and 295/25/22 (R). Over the last couple days, I have tried to take the car to get the wheels/tires...

Hey Folks, I have a 2016.5 Model S P90D. I saw in the Classifieds section of the forum a while back a vendor offering a 90 kWh battery for sale, along with upgrades to ludicrous for anyone who bought it. That leads me to ask - now that Tesla no longer offers the upgrade from the factory...

Hey Folks, I have a 2016 Model S with Air suspension. Over the past week or so, I have noticed that the rear end of the car is fairly consistently about 1.5 inches higher than it should be, giving the car a funky looking stance. I do notice that sometimes it sits level (where it should), but...
