With the key in the ignition, but not turned, Press and hold down the mileage indicator button. Whilst still depressed turn the ignition key. At this point the mileage indicator will count down from 9-0. When it hits 0 release the button. There you have it - 20000 miles. Note my car is a non-multiplex car, but I would imagine it is the same for all.
Yes- with the oil situation. I was under the impression that the type of oil used for the service is semi-synthetic or better. Which if they had put that in my car originally there wouldnt have been a problem. I was going to supply my own fully synthetic oil at the time of the service, but there was no reduction in cost and thought in that case I may as well let them use there semi-synthetic as a kind of a engine flush and then refill with my own fully synthetic oil when I got home. If you exclude the time it takes for the oil to drain then its only 5- 10 minutes.
It is possible that the oil I drained after the service was new. I do not know the colour of magnetec oil, but I am pretty sure it isn’t black. And like you say Alex magnetec is semi-synthetic and the oil used previous to the service was fully synthetic. I am hoping there is an easy way of testing for this difference.
As yet I have not had a reply from the service department. I just wish garages would do exactly what they are supposed to do without trying to find extra work and/ or cut corners. Its about the only industry that can get away with stuff like this and when it comes to my pride and joy I get a little irate.
206 cc is a great French car let down by Peugeot UK.
