I wonder if anyone has mastered the complexities of the Service Indicator when set for variable / Longlife oil etc ? Is a 2009 140 BHP CR TDI. I know there is a sensor for "Oil Condition" (Had various explainations on how this works...for instance Optical sensor to see how black the oil is or another theory is to see how the oil handles temperature etc).
Anyway my issue is that I had it serviced back in Feb2017 and used Castrol Edge. I had an op & vehicle was laid up for 2.5 months. The indicator hadn't set itself before being laid up (which is usual, it takes about 300 miles to shows "Miles to go" & "Days left".
After I started using it week before last the 300 miles or so hadn't been met but last week I did manage to get it to 300 miles or so after Service carried out & it first came up with 17100 miles ......so it lost about 1700 miles below what it should be.........then over the next few days it gradually crept up till yesterday it got to 18500 which was about right. Most of the journeys were M27 at speed limit. Then today I did a trip and it was 18300, I drove back along M27 about 12 miles and it dropped to 15600 miles to next service yet it has only done 350 miles since service.
Does the indicator calculation /Analysis /alogritham etc take time to settle down because at this rate I'll be having a service in a couple of months !
Thanks,
Paul
