G'day all, my 2020 D300 (140,000km as at May 2025) began to misfire / hesitate on acceleration recently. Took it to LR dealer who diagnosed blocked EGR high pressure side (whatever that means). Attempted to clean. No good. Now have been told (5 weeks after the unit went into the workshop) that the EGR needs replacement. Car is in Brisbane, Australia. Dealer says EGR needs to come from UK and is 6 to 8 weeks delivery. Has anyone had issues with EGR and misfiring that has been fixed quicker than this?
