monkie Posted August 3, 2022 Share Posted August 3, 2022 My boss has a 2019 D5 fitted with the Ingenium 2.0 Diesel engine. Wondering if any can point us in the right direction of any known issues with top end knock. He had an issue recently where the engine would cut out but then restart and around the same time has a top end knocking noise that is getting more pronounced. Someone from a 4x4 specialist read fault codes (nothing stored), suspected a turbo fault (nothing), removed the injectors and sent away for testing (apparently they check out okay but only mentioned spray pattern), no sign of a dropped valve. They are now saying ot could be a camshaft or balancer shaft issue. That sounds like a guess to me as the engine will run (albeit with a knock). Anyone have any thoughts? I'm still wondering if any potential fuel system fault is sitting there undiagnosed. Balancer shaft makes no sense to me for a top end noise and camshaft fault? I would have thought that anything odd there would be evident with top cover off the head? Quote Link to comment Share on other sites More sharing options...
smallfry Posted August 3, 2022 Share Posted August 3, 2022 Not that I have any idea, but is it a diesel knock, or mechanical ? Constant or intermittent ? Losing any coolant ? Hydraulic valve lifter ? Trouble with the DPF, is that it will filter out any smoky clues, so I'm told. Quote Link to comment Share on other sites More sharing options...
monkie Posted August 3, 2022 Author Share Posted August 3, 2022 From how it's been described to me, it sounds like diesel knock (pronounced when cold). Constant but was getting worse. Quote Link to comment Share on other sites More sharing options...
Waldorf Posted August 4, 2022 Share Posted August 4, 2022 The 2.0 in the Disco5 is well known for causing trouble. A friend of mine had one as a company car, and the check-engine light came on every other week. The dealer replaced pretty much everything around the engine: radiator, oil pump, thermostat, turbo, EGR,... Each time without result. Eventualy they replaced the engine, and even then the engine light kept coming back and the car went into limp mode. According to my mate LR are replacing these engines under warranty in high numbers. I am sure there is more info about this on the Disco5.co.uk forum. 1 Quote Link to comment Share on other sites More sharing options...
