Firstly, apologies in advance for my lack of knowledge about cars. We bought a new diesel Discovery Sport in November last year, and my DH was a bit nervous about potential issues with the oil particulate not being able to clear itself unless the car was driven for long distances at high speeds very regularly. However, he was reassured that this wouldn't be an issue if we were taking the car out for at least one longer, faster drive at the weekend, which we do.
We both live very close to where we work so the car is mostly used during the week for the school run - a couple of miles a day on weekdays, and then we tend to use it more at the weekend, when it gets a longer run.
DH has just come back from the Land Rover garage after a service light came on the car, and he's had to have the oil filter changed, as it's not getting enough opportunity to clear itself. Land Rover tried to charge him £200 but he said that was completely unreasonable, so they reluctantly agreed not to charge him.
He asked for specific guidance about how much the car needs driving to clear the particulate and was told it needs be to driven at 50mph for at least 20 mins twice a week. The 50mph needs to be constant for the 20minutes, otherwise the cleaning process is interrupted and won't continue.
This is pretty challenging for us; even on a motorway it's not always easy to drive at 50mph or over for 20 mins. The salesperson told DH that a lot of customers were having this problem with diesel cars. Has anyone else had this problem, and how did you overcome it? I really don't want to change the car, as we've only had it six months and I really like it. Thanks
