Oil dilution, 9-speed gearbox and campaigns on the Compass II

Engine / equipment

Jeep Compass II (petrol, diesel and 4xe)

Period mentioned

2016 onwards

Symptoms

Oil dilution on the 1.4 MultiAir with short trips; carbon on the petrols; a ZF 9-speed (4x4) with jolts and humming between 4th and 5th in town; rust on door edges on early cars, worn track rods at the roadworthiness test and interior rattles before the 2020 facelift.

Possible cause described

The shift jolt comes from decoupling the rear axle; the software update only moves it to another speed. Recalls: light sensor (2016–2017), fire extinguisher (up to 2018), cruise control (up to 2019), rear calipers (17/3–21/6/2018) and the wiper ball joint (28/4/2019–3/3/2020).

Check for the garage

Check every campaign by VIN; watch the oil level; test the gearbox in town.
