Thread: Are OZ disco 5 suffering from fuel in oil and early service warning issus?

A member on disco5.co.uk asked his dealer how the service indicator worked, they asked LR. The response was this (slightly rephrased from the original post):

Distance to next service is variable. The system has 3 factors to calculate the distance to next service. These factors are; Oil dilution; distance; days to next service. Each of them are represented as a distance, even the "days to service". The "days to service" system measures an average distance within a certain time range. For example - when a customer normally drives about 1,000km per month then the next maintenance would be in 12,000km as time wise that would mark the end of a year. If for example maintenance has to be done in 10 months, the distance to service indicator would show 10,000km. If the customer changes the monthly distance driven to 500km, the system recalculates the next service due to be in 5,000km.

Thanks Ron,

I wonder then if this number can grow as well as reduce, say if your daily travel increases ... could be interesting this next 10 days as I'm travelling

I had the latest oil dilution software update @ 25,000km Service, just before Christmas 2018 ( after 3 early oil services ), happy to report ( and fingers crossed ) that I have now done 5000km since Christmas 2018 and the next service is showing in 20,000km, so the latest software update appears to be working.

i have also been taking oil samples, the first sample showed a lot of metal, and the next two have been perfect with no signs of oil dilution.

I was back to the dealership every 5 to 6 weeks before the update for a oil service, which was absolute pain, I’m hopeful that they have solved the issue, I’m getting another oil sample in 5000km ( the oil will be 10,000km old ) and will see if the oil has any oil dilution, which to be honest I’m not expecting any.

The whole thing is very frustrating, but if it doesn’t pan out, I think there will be a long que seeking retrubution.....

There was some conjecture between the three service staff(Manager & two advisors) whether or not software had been applied in either of the first two visits.
Your results Jack seem to make me think perhaps not!

LRA had not been made aware there were any issues with this car(ie. they confirmed there were no "Cases" raised with them).
LRA should definitely be involved with the Dealer next week(there IS now a "Case"), so we will see what comes next now ...

Les.

Is the oil dilution real or imagined?

Imagined. Which is why MY18 vehicles can be fixed with a software update.

I'm tending to believe it's largely imagined, although they may well have changed something in the design of the exhaust to MY18 vehicles.

Makes my situation & inconvenience even more rediculous if it were only imagined though.

On the UK disco 5 forum so many people complained about the fuel in oil resulting in early oil changes, plus frequent Adblue refill could see your beloved disco in dealer garage 4 or 5 times within 6 months. Also there is a concern about engine damage on long run. These issues don't seem to be complained about by OZ owners, what is the magic here? Thanks in advance.
