Mercedes-Benz ML (M-Class) diagnostics
Mercedes-Benz ML (M-Class) (1997–2015): free AI diagnosis by symptoms, fault codes or a dashboard photo — plus OBD-II reading right in the browser.
What usually goes wrong on the Mercedes-Benz ML (M-Class)
- На W164 с OM642 3.0 CDI течёт уплотнение маслотеплообменника в развале блока — классика этого мотора.
- Вихревые заслонки впускных коллекторов и EGR закоксовываются сажей, ломаются тяги приводов — тряска и потеря мощности.
- Пневмоподвеска Airmatic на W163/W164: пробой пневмостоек и износ компрессора с ошибкой уровня кузова.
- На бензиновых ML350 2005–2008 с M272 изнашивается шестерня балансирного вала, а по всему семейству текут сальники переднего редуктора и раздатки.
