I purchased my Discovery Sport TD4 180 from new some 12 Months ago. Within 5 Months, the Service Indicator came on. The car at that time had done approximately 3500 miles. An oil change was needed. I subsequently booked my car in and had the oil and filter changed in June of this year, over 8 weeks later at 4500 miles ( This was the earliest date available at my local dealer at the time) they found 10 % oil dilution and performed the required oil change
In November of this year, the service light came on again at 6500 miles indicating I needed another oil change. This oil change was again performed by the local dealer last week at 7300 miles with a 7.5% oil dilution value. Whilst I was told this oil change would be free ( As I have a Service Plan ) The dealer in question informed me that they would only perform another 3 max oil changes, under the plan. So in effect using up my service credits, by all accounts, rather than replacing the oil and filter under warranty?
Understandably I'm not particularly happy. As the dealer has indicated that they will start charging for this in the near future?
Whilst I do mostly suburban driving 90% of the time, my vehicle is used on the motorway around 10% of the time and at least once every 3 weeks I do a 40+ mile motorway journey, travelling on or near the max speed limit. I have also made additional unnecessary motorway journeys when the DPF regeneration warning has come on, which it does periodically.
However, this seems to have made very little difference, given the frequency of my oil changes. I've read a couple of technical articles which make interesting reading, Whilst I can't vouch for there authenticity, they appear to be professional engineering reports about the Landrover Discovery Sport and Evoque Diesel engines and include the specific DPF issue.
My understanding is that there is a serious design fault. The article states that the Diesel particulate filter has been placed a lot lower down the exhaust system in these models and is effectively far too far away from the engine to get hot enough to burn off and vaporise the soot during passive regeneration. Effectively resulting in oil contamination. Active regeneration only occurs when driving the car at high speed and realistically this can only be done whilst driving on a motorway regularly.
My understanding is that there is no actual fix, as far as I'm aware. Perhaps someone can otherwise confirm if this is correct or not?
Had I know about this issue, I would never have purchased the Discovery Sport. I was also given the sale literature, by Land Rover before I purchased, (Now withdrawn) that stated a 21000 mil service interval.
Interesting my local Land Rover dealer tried to get me to sign a disclaimer, when I last went in, to indicate that I'm fully aware of the DPF warning and how best I should drive my Vehicle?
Frankly, I found the whole thing quite bizarre and somewhat insulting, See attached document. Obviously, I declined to sign it and return it. Has anyone else been handed this document? Please see the attached. In all likelihood, I'll be speaking to Land Rover customer service in the very near future.
