R-Link, particulate filter and EGR on the Koleos IIKnown weak points

Engine / equipment: Renault Koleos II (1.3 TCe and dCi)
Period mentioned: 2016 onwards
Symptoms: R-Link with Bluetooth problems or freezing after an update, a squeaking centre console; on diesels, a particulate filter clogged by short trips and carbon on injectors and EGR.
Possible cause described: The guide finds no weak points in the 1.3 TCe; the diesels have the typical high-mileage wear (dual-mass flywheel, turbo, EGR, injectors).
Check for the garage: Drive long trips to regenerate the filter; ask for R-Link updates; test injectors and EGR on diesels.

Period mentioned: Approx. 2005–2023
Symptoms: Chain noise at high mileage; loss of power and emissions warnings in town use; injectors that will not come out when removed.
Possible cause described: The chain can stretch at high mileage, the injectors can seize in the cylinder head and, with short trips, the particulate filter and EGR clog.
Check for the garage: Listen to the chain from cold, check injection and emissions codes, and before removing injectors have extraction tools ready. Keep oil changes up to date.
