3 known faults with sources

Engines: 2.0 / 2.4 (Petrol) · 2.0 / 2.2 CRD (Diesel)

Coolant leak and body control module on the Compass and PatriotElectrical and electronic systems

Engine / equipment: Jeep Compass I and Patriot (petrol and diesel)
Period mentioned: 2007–2016
Symptoms: A cooling-system leak; odd electrical faults (lights staying on, stalks and locks not responding) that go away after disconnecting the battery.
Possible cause described: Between 2011 and 2015 Jeep contacted owners for preventive maintenance against the coolant leak. The electrical faults point to a poor earth on the body control module (BCM). On the VW-sourced 2.0 diesel, belt, tensioner and water pump are changed every 4 years or 96,000 km.
Check for the garage: Check whether the preventive action was done; watch the coolant level and the BCM earths.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Engines: 2.0 / 2.2 CRD (Diesel)

Applies if: Only the 2.2 CRD (from 2011), which is the Mercedes OM651.

Chain, injectors and coolant leaksTiming / injection

Engine / equipment: OM651 2.1/2.2 CDI (C 200/220/250 CDI, E 200/220/250, GLK, Vito, Sprinter)
Period mentioned: 2008 onwards
Symptoms: Chain rattle on a cold start; on early units, loud injector knocking; coolant loss from the plastic coolant manifold or the EGR cooler.
Possible cause described: Plastic chain guide and a hydraulic tensioner that loses pressure (the chain is at the rear). Early units used problematic piezo injectors that Mercedes replaced in a campaign.
Check for the garage: Listen to a cold start, check the dealer's injector campaign history and check the coolant level.
Cost cited in the source: Chain: approx. €1,500–3,000 (estimate)A rough figure from the original database, not an up-to-date quote.

Engines: 2.0 / 2.2 CRD (Diesel)

Applies if: Only the 2.0 CRD, which is the VW 2.0 TDI unit-injector engine.

PD TDI camshaft, injectors and cylinder headInjection / cylinder head

Engine / equipment: 1.2, 1.4, 1.9 and 2.0 TDI unit-injector (PD) engines, including the VW-sourced 2.0 CRD in Chrysler, Dodge and Jeep
Period mentioned: 2000–2010
Symptoms: Growing noise from the cylinder head, power loss and rough running (cams and lifters); unstable idle, smoke or hesitation (injectors); on the 16-valve 2.0 TDI, coolant loss with no visible leak from a cracked head.
Possible cause described: The camshaft also drives the unit injectors and carries a heavy load: without VW 505.01 oil the lobes and lifters wear. 2.0 TDI PD injectors fail frequently. Some 16-valve 2.0 TDI heads (part number ending in A) crack; VW considered it fixed by the end of 2006.
Check for the garage: Check the oil history (VW 505.01), listen to the head, check injector balance rates with a diagnostic tool and, on the 16-valve 2.0 TDI, read the head part number (03G 103 351) and look for coolant loss.
Cost cited in the source: Camshaft and lifters: approx. €400–800; 2.0 TDI PD injectors: €900–2,000A rough figure from the original database, not an up-to-date quote.

Mileage cited in the database: 120,000–200,000 km. This is not a maintenance interval and does not predict a failure.
