Porsche 911 · 2020–2026
Porsche Technical Information 40/21 ENU 4381 covers 911 Carrera (992) cars from model year 2020 fitted with the front-axle lift function (M-no. 2UH). The white warning message "Lift system fault - Service necessary" appears in the instrument cluster and the entry "C1365F8 - Measuring height fault (000302)" can be stored in the front-axle lift system control unit. Porsche states plainly that "this fault type can occur if the vehicle was parked with the body front end raised," and warns owners to "always park the vehicle at the lowered position, as the upper holding position cannot be guaranteed over a long period of time with the engine stopped." A large share of these faults are therefore induced by how the car is parked rather than by a failed component. Owners on Rennlist separately report hydraulic failures where the system lifts but will not come back down, and a case of a lift strut boot blowing out at around 7,500 miles and spraying hydraulic fluid into the wheel well - so a genuine hydraulic leak still has to be ruled out before assuming a parking-induced code.
Common Symptoms
- White "Lift system fault - Service necessary" message in the instrument cluster
- Front axle lift raises but will not lower
- Lift button indicator stays red or does not respond
- Hydraulic fluid in the front wheel wells or on the lift strut boot
How to Fix
Lower the front axle before switching off the engine, every time - this is Porsche's own instruction and the single most effective preventive measure. If the warning message and the height-measurement entry are both displayed, the workshop must perform the front ride-height measurement and check per TI 40/21 before condemning parts. Inspect the lift strut boots and fittings for hydraulic fluid in the wheel wells: leaky fittings are a separate, real failure that also triggers this message and will not be cured by clearing the code.

Frequently asked questions
What does C1365 mean?
C1365 stands for "Front-Axle Lift System - Measuring Height Fault." The front-axle lift control unit has read a height-measurement value it cannot reconcile with the commanded lift state - typically the measured ride height does not match the position the system believes it is holding. Porsche Technical Information 40/21 (ENU 4381) documents C1365F8 "Measuring height fault (000302)" on the 911 (992), noting it commonly appears when the car was parked and left with the front end raised, because the raised holding position cannot be maintained indefinitely with the engine off.
What are the most common causes of C1365?
The most common causes of C1365 are: Vehicle parked and shut down with the front axle lift raised, allowing the front end to settle overnight, Height sensor out of calibration after suspension or bumper work, Hydraulic lift system leak-down or low pressure, Faulty front ride-height sensor or wiring. The specific cause varies by vehicle.
How much does it cost to fix C1365?
Repair costs for C1365 range from $200 to $3,000, depending on the vehicle and root cause.
