PART 1: SAMPLE ASE-STYLE PRACTICE QUESTIONS
Original questions written in ASE format — scenario-based with 4 options
A1 — ENGINE REPAIR
Q1. A 2023 BMW X3 (B48 engine) arrives with a rough idle and P0302 (cylinder 2
misfire). The technician notices oil contamination in the spark plug well of cylinder 2.
Technician A says the valve cover gasket is leaking and oil is shorting the coil. Technician
B says the spark plug tube seals are integrated into the valve cover and the entire cover
must be replaced. Who is correct?
• A. Technician A only
• B. Technician B only
• C. Both technicians
• D. Neither technician
Answer: C. Both technicians
Explanation: On BMW B-series engines, the spark plug tube seals are indeed molded into
the valve cover and are not serviceable separately. Oil in the plug well will cause coil
shorting and misfire. The complete valve cover assembly must be replaced.

Q2. During a timing chain inspection on a 2020 BMW 330i (B46), the technician finds the
chain has stretched beyond specification. Which component should ALWAYS be
replaced along with the timing chain?
• A. VANOS solenoids only
• B. Chain tensioner, guides, and sprockets
• C. Oil pump only
• D. Camshaft position sensors
Answer: B. Chain tensioner, guides, and sprockets
Explanation: BMW TSBs and repair logic dictate that stretched chains have worn the
tensioner, guides, and sprockets. Replacing only the chain will result in rapid re-failure due
to mismatched wear patterns.
A2 — AUTOMATIC TRANSMISSION
Q3. A 2022 BMW 530i (GA8HP51Z) exhibits harsh 2-3 upshifts only when cold. No DTCs
are stored. Fluid level is correct and clean. The most likely cause is:
• A. Failed clutch E (C3) friction plates
• B. Incorrect adaptive shift values / relearn required
• C. Torque converter lock-up clutch failure
• D. Output speed sensor intermittent fault
Answer: B. Incorrect adaptive shift values / relearn required
Explanation: ZF 8HP transmissions rely heavily on adaptive pressure values. Harsh shifts
when cold without DTCs strongly suggest adaptation drift. A transmission adaptation
reset/relearn via ISTA should be performed before replacing hardware.
