Mercedes-Benz GLA — 真实案例
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.
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.
