Fault code
2A8D - P0024
Fault text
Exhaust VANOS, adaptation stop 2
Fault description
'B' Camshaft Position - Timing Over-Advanced or System
Performance (Bank 2)
Condition for fault identification
Test condition:
Bank 2 exhaust travel-limit adaptation monitor
(if OK: 58�KW < Vsa2_adp < 84�KW)
VANOS must be at travel limit, i.e., Vsa2_sprs=120�KW.
Terminal condition: KL_15 = true
Voltage condition:
none
Condition for fault memory entry
Entered immediately
Action in service
Test sequence (check to determine whether fault is still
present after each step):
1. If corresponding camshaft sensor fault has been logged,
start by checking camshaft sensor
2. Check VANOS valve for contamination
3. Check reluctor position
4. Check chain length and tension
Fault effect and breakdown warning
Driver information
Warning light:
US: Standard OBD fault; MIL on after 2 driving cycles,
transmits to scan tool; no EPCL; delete fault after 40 warm-
up cycles
ECE: AS US but no MIL
Service instruction
none

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
