What code APP_w048 means

The application layer of Autopilot. Drives adaptive cruise control, lane keeping, lane changes and sign recognition. Faults here usually mean an assistance feature switched itself off temporarily — typically due to poor visibility or incomplete camera calibration.

Severity — w

The car is flagging that something is not right. Driving is usually still possible, but some function may be limited.

Internal alert name

This is how the fault is named inside the car's firmware. For codes without a description it is the most precise clue there is — the name itself says what the event is about.

APP_w048_APP_Features_Disabled

We do not have a detailed description for this code yet

Tesla only publishes descriptions for some codes. What we do know for certain is its classification and the internal name above — and from those you can reliably tell which part of the car it concerns.

Driver experiences with code APP_w048

This part is written by you. If you have had code APP_w048, tell us when it appeared, what brought it on and how it ended — for the next person, one such sentence is often worth more than the entire service documentation.

Na displeji se objeví „Self-Driving features temporarily unavailable“, případně „Driver Assistance Features Unavailable“. Je to souhrnná hláška: vůz oznamuje, že asistenční funkce jsou dočasně mimo provoz, ale sám o sobě neříká proč. Tohle je důležité pochopit. APP_w048 se nikdy neobjevuje samotný — vždycky ho doprovází další kód, který popisuje skutečnou příčinu. Ten první je jen to, co uvidí řidič; ten druhý je to, co uvidí technik v diagnostice. Hledat řešení podle APP_w048 proto nikam nevede. Příčiny bývají banální i vážné: zanesené nebo oslněné kamery, nedokončená kalibrace po výměně skla, radar nebo ultrazvukové senzory pod vrstvou soli a bláta, hustý déšť a mlha, ale i skutečná závada jednotky Autopilotu. Co s tím: nejdřív očistěte čelní sklo v místě kamer za zpětným zrcátkem a přední masku. Pokud hláška zmizí po dalším nastartování, šlo nejspíš o počasí nebo dočasné oslnění. Když drží i za dobré viditelnosti, nechte si v servisu vyčíst, jaký kód ji doprovází — teprve ten řekne, co se opravuje. Týká se Modelu S 2012–2020 a Modelu X 2015–2020.

Im Display erscheint „Self-Driving features temporarily unavailable“ oder „Driver Assistance Features Unavailable“. Das ist eine Sammelmeldung: Das Fahrzeug teilt mit, dass die Assistenzfunktionen vorübergehend nicht verfügbar sind, sagt aber von sich aus nicht, warum. Das ist der springende Punkt. APP_w048 tritt nie allein auf — es begleitet ihn immer ein weiterer Code, der die eigentliche Ursache beschreibt. Der erste ist nur das, was der Fahrer sieht; der zweite das, was der Techniker in der Diagnose sieht. Nach APP_w048 eine Lösung zu suchen führt deshalb ins Leere. Die Ursachen reichen von banal bis ernst: verschmutzte oder geblendete Kameras, nicht abgeschlossene Kalibrierung nach einem Scheibentausch, Radar oder Ultraschallsensoren unter einer Schicht Salz und Schmutz, starker Regen und Nebel, aber auch ein echter Defekt des Autopilot-Steuergeräts. Was tun: Reinigen Sie zuerst die Windschutzscheibe im Bereich der Kameras hinter dem Innenspiegel sowie die Frontpartie. Verschwindet die Meldung beim nächsten Losfahren, lag es höchstwahrscheinlich am Wetter oder an kurzzeitiger Blendung. Hält sie auch bei guter Sicht an, lassen Sie in der Werkstatt auslesen, welcher Code sie begleitet — erst der sagt, was repariert wird. Betrifft Model S 2012–2020 und Model X 2015–2020.

Na ekranie pojawia się „Self-Driving features temporarily unavailable”, albo „Driver Assistance Features Unavailable”. To komunikat zbiorczy: auto informuje, że funkcje wspomagania są chwilowo niedostępne, ale samo z siebie nie mówi dlaczego. To trzeba zrozumieć. APP_w048 nigdy nie pojawia się sam — zawsze towarzyszy mu inny kod, który opisuje prawdziwą przyczynę. Ten pierwszy to tylko to, co widzi kierowca; ten drugi to, co widzi technik w diagnostyce. Szukanie rozwiązania po APP_w048 do niczego więc nie prowadzi. Przyczyny bywają błahe i poważne: zabrudzone lub oślepione kamery, niedokończona kalibracja po wymianie szyby, radar albo czujniki ultradźwiękowe pod warstwą soli i błota, gęsty deszcz i mgła, ale też realna awaria sterownika Autopilota. Co z tym zrobić: najpierw wyczyść przednią szybę w miejscu kamer za lusterkiem oraz przód auta. Jeśli komunikat zniknie po kolejnym uruchomieniu, chodziło najpewniej o pogodę lub chwilowe oślepienie. Gdy utrzymuje się także przy dobrej widoczności, poproś serwis o odczytanie, jaki kod mu towarzyszy — dopiero on powie, co się naprawia. Dotyczy Modelu S 2012–2020 i Modelu X 2015–2020.

The screen shows “Self-Driving features temporarily unavailable”, or “Driver Assistance Features Unavailable”. It is an umbrella message: the car is announcing that assistance features are temporarily out of service, but on its own it does not say why. That is the key thing to understand. APP_w048 never appears alone — it is always accompanied by another code describing the actual cause. The first is what the driver sees; the second is what the technician sees in diagnostics. Looking for a fix based on APP_w048 therefore leads nowhere. Causes range from trivial to serious: dirty or dazzled cameras, calibration not finished after a windscreen replacement, radar or ultrasonic sensors under a layer of salt and grime, heavy rain and fog, but also a genuine fault in the Autopilot computer. What to do: first clean the windscreen in front of the cameras behind the mirror, and the front of the car. If the message clears on the next drive, it was most likely weather or temporary glare. If it holds even in good visibility, have a service centre read out which code accompanies it — only that one tells you what is being repaired. Applies to Model S 2012–2020 and Model X 2015–2020.

What to do about it

01

Write down the whole code

Copy it exactly, letter and number included. Photographing the screen is safest — codes often differ by a single digit, and mixing them up leads somewhere else entirely.

02

Try letting the car sleep and wake

Some codes clear after a screen restart or after the car sits locked for a few hours. If the code does not come back, it was usually a one-off glitch.

03

Watch whether it repeats

A one-off entry and a code that appears after every drive are two different things. It helps a service centre enormously if you know exactly when it shows up.

04

Do not wait on safety systems

With airbags, brakes, steering and high voltage there is no point waiting it out. With the other groups you can watch and see whether the code returns at all.

Before you act on a code. This page is a reference dictionary, not a repair manual. It explains what an abbreviation means and what it relates to — it does not diagnose your car. The same code can have different causes, and its meaning also shifts between firmware versions. For anything involving brakes, steering, airbags or high voltage, go straight to a service centre.
