Real GLA cases at 4M Car Care: X156 M270 cam cover seal leak at 90,000 km, H247 DCT fluid service at 40,000 km (smooth shifts restored), rear shock replacement at 85,000 km. Actual costs.
Real GLA cases from 4M Car Care, Bandar Sri Damansara. Costs reflect 2024–2025 pricing.
Case 1 — GLA 200 X156, 67,000 km: DCT judder + service history gap
Owner bought used at 52,000 km with incomplete service history. Judder present from day one of ownership. XENTRY scan: no stored faults. 7DCT fluid: dark, no service record found. DCT fluid flush performed. 7DCT adaptation reset via XENTRY. Judder reduced by 80% — slight residual judder pointed to mild clutch wear. Owner informed and advised to monitor. Total cost: RM 450.
Case 2 — GLA 250 4MATIC H247, 33,000 km: Vibration on hard cornering
Owner complained of a vibration and slight resistance when cornering sharply on a roundabout — not present on gentle curves. XENTRY scan: no faults. Tyre check: all four same brand but front-left had slight inner wear. Transfer case fluid: original fill, no issues. Diagnosis: incorrect wheel alignment causing the 4MATIC rear clutch to engage under lateral load. 4-wheel alignment performed — all four wheels were out of spec. After alignment, cornering vibration gone. Total cost: RM 120.
