在濟南，奔馳汽車維修服務涵蓋從日常保養到復雜故障修復的全方位需求。依托品牌技術標準與本地化服務經驗，維修項目可系統劃分為五大核心板塊，每個板塊均遵循原廠規范，確保車輛性能與安全。

　　In Jinan, Mercedes Benz car repair services cover a comprehensive range of needs from daily maintenance to complex fault repair. Based on brand technical standards and localized service experience, maintenance projects can be systematically divided into five core sections, each of which follows original factory specifications to ensure vehicle performance and safety.

　　一、常規保養體系

　　1、 Routine maintenance system

　　機油機濾更換

　　Oil filter replacement

　　采用符合奔馳MB 229.5認證的低粘度全合成機油，針對M274、M276等不同發動機型號，機油加注量精確至0.5L誤差范圍。機濾更換時同步檢查放油螺栓磁性吸附的金屬碎屑，判斷發動機內部磨損狀態。

　　Using low viscosity fully synthetic engine oil that complies with Mercedes Benz MB 229.5 certification, the oil filling amount is accurate to within an error range of 0.5L for different engine models such as M274 and M276. During the replacement of the engine filter, check the metal debris magnetically adsorbed on the oil drain bolt to determine the internal wear status of the engine.

　　制動系統養護

　　Brake system maintenance

　　每2萬公里進行制動液含水量檢測，超過3%立即更換。剎車片磨損極限為3mm，采用原廠陶瓷基配方，搭配打孔通風制動盤，確保連續制動時熱衰減溫度＞600℃。

　　Perform brake fluid moisture content testing every 20000 kilometers, and replace immediately if it exceeds 3%. The wear limit of the brake pads is 3mm. The original ceramic based formula is used, combined with perforated ventilated brake discs, to ensure that the thermal attenuation temperature during continuous braking is greater than 600 ℃.

　　易損件周期管理

　　Cycle management of vulnerable parts

　　空氣濾清器每4萬公里更換，空調濾芯每2萬公里更換，采用HEPA級濾材，對PM2.5過濾效率≥99%。雨刮片根據膠條開裂情況提前更換，避免刮拭殘留影響行車視線。

　　The air filter is replaced every 40000 kilometers, and the air conditioning filter element is replaced every 20000 kilometers. It uses HEPA grade filter material and has a PM2.5 filtration efficiency of ≥ 99%. Replace the wiper blades in advance according to the cracking of the rubber strip to avoid wiping residue that may affect the driving vision.

　　二、深度診斷與修復

　　2、 Deep diagnosis and repair

　　發動機故障解析

　　Engine Fault Analysis

　　對M264發動機，重點檢測48V電機BSG皮帶張力，使用原廠VCI診斷儀讀取曲軸箱通風閥數據流，異常波動超過±5%需進行碳罐電磁閥清洗。對于V6、V8機型，采用內窺鏡觀察氣門積碳情況，必要時進行核桃砂物理清洗。

　　For the M264 engine, the focus is on detecting the tension of the 48V motor BSG belt. The original VCI diagnostic instrument is used to read the data flow of the crankcase ventilation valve. If the abnormal fluctuation exceeds ± 5%, the carbon canister solenoid valve needs to be cleaned. For V6 and V8 models, use an endoscope to observe valve carbon buildup and perform walnut sand physical cleaning if necessary.

　　底盤系統調校

　　Chassis system calibration

　　針對AIRMATIC空氣懸架，使用Star Diagnosis診斷儀進行水平校準，誤差超過10mm需檢查氣泵工作壓力。對AMG車型的后輪轉向系統，檢查轉向角傳感器零位偏差，超過0.5°需執行四輪定位與ECU復位。

　　For AIRMATIC air suspension, use the Star Diagnosis diagnostic tool for horizontal calibration. If the error exceeds 10mm, check the working pressure of the air pump. For the rear wheel steering system of AMG models, check the zero position deviation of the steering angle sensor. If it exceeds 0.5 °, perform four-wheel alignment and ECU reset.

　　變速箱維護方案

　　Transmission maintenance plan

　　7G-TRONIC PLUS變速箱每6萬公里更換原廠變速箱油，采用循環機換油法，確保舊油置換率≥90%。對9G-TRONIC變速箱，重點監測離合器片磨損導致的換擋沖擊，通過TCU數據流分析電磁閥響應時間。

　　The 7G-TRONIC PLUS transmission changes the original transmission oil every 60000 kilometers, using a circulation machine oil change method to ensure that the old oil replacement rate is ≥ 90%. For the 9G-TRONIC transmission, focus on monitoring the shifting shock caused by clutch plate wear, and analyze the response time of the solenoid valve through TCU data flow.

　　三、鈑金噴漆工藝

　　3、 Sheet metal painting process

　　鋁車身修復技術

　　Aluminum body repair technology

　　針對奔馳車型廣泛采用的鋁合金覆蓋件，使用鋁焊機進行MIG脈沖焊接，焊縫強度達母材85%以上。對碳纖維復合材料部件，采用真空導入法修復，確保層間剪切強度≥50MPa。

　　For the aluminum alloy coverings widely used in Mercedes Benz models, MIG pulse welding is performed using an aluminum welding machine, with a weld strength of over 85% of the base material. For carbon fiber composite components, vacuum induction method is used for repair to ensure interlayer shear strength ≥ 50MPa.

　　水性漆噴涂流程

　　Water based paint spraying process

　　使用PPG或BASF水性漆，色漆層厚度控制在15-18μm，清漆層厚度45-50μm。噴涂環境保持25℃恒溫，濕度≤60%，通過分光測色儀確保色差ΔE≤1.5。
