Richard Fairhurst Posted September 28, 2004 Posted September 28, 2004 Our dealer (Reg Vardy in Banbury, very helpful so far) say our Pluriel needs to go in for another recall - sounds like a software upgrade. Anyone know any more? Incidentally, nice piece in today's Independent on the Pluriel, one page after a pic of the new C4 which looks _very_ C3-like. Richard Quote
hertsnminds Posted September 29, 2004 Posted September 29, 2004 It is possible that it is an existing recall that your car has missed out on rather than a new one. you can have a look on this website [url="http://www.c3pluriel.org.uk/"]http://www.c3pluriel.org.uk/[/url] In the questions section there is a recall codes link and a how to check what recalls have been done to your car. When you get the upgrade done it would be helpful if you could ask your dealer for the code (not all of them put the stickers on) and let me know then I can add it to the list on the website. Thanks.

Will let you know what transpires. Richard Quote
Richard Fairhurst Posted November 3, 2004 Author Posted November 3, 2004 It's a new one! X12 - engine management upgrade, apparently. We're having it done next week. Quote
hertsnminds Posted November 3, 2004 Posted November 3, 2004 Thanks Richard I will add it to the web site list Ian Orange 03 Senso Quote
Richard Fairhurst Posted December 8, 2004 Author Posted December 8, 2004 After a few weeks of running with it... Car now pulls better uphill, particularly in 4th and 5th gear. Economy has been reduced by several mpg, at least according to the on-screen display. I used to average 44.7 mpg on the way to work - it's now more like 41.4-42.7. I think I preferred it as it was... (Incidentally, our dealer said it took around an hour to upload the new software! How big is the ROM in these things? Or are they using a 1984-vintage 1200/75 connection?) Quote
hertsnminds Posted December 8, 2004 Posted December 8, 2004 Someone should tell them about broadband :) I would hope the code is very small and efficient, maybe that's the reason nothing works, too many IF THEN statements to sift through!!! Better pull and worse MPG sounds like they have made the engine rev more, have you noticed higher revs for the same speeds? Ian Orange 03 Senso Quote
dobbin Posted December 9, 2004 Posted December 9, 2004 Surely higher revs for the same speeds would require a mechanical change in the gearbox rather than just a software upgrade? I guess it might be something to do with the amount of fuel being injected per cycle. Quote
hertsnminds Posted December 9, 2004 Posted December 9, 2004 You are correct, but if the fuel/air mix has been made more fuel rich (a trick some chipping companies use to give more power) things like idle revs may have changed as well as the power required to achieve a certain speed. Going up hill at 70MPH requires more grunt than coasting down hill at 70MPH. The software also controls variable valves or cams (not sure if the Citroen engine uses this trick) but in a Honda VTEC engine this totally changes power outputs and fuel consumption when revs reach the high end.

dobbin Posted December 9, 2004 Posted December 9, 2004 That makes more sense - more 'grunt' for the same speed, rather than more revs for the same speed. :) Quote
Richard Fairhurst Posted June 25, 2005 Author Posted June 25, 2005 Several months on, the MPG read-out is still a lot less than it was before the recall - my journey to work turns out at about a 38mpg average now, when it used to be 42.7mpg. So I did a bit of calculation and worked out my own mpg figure from the amount of petrol I'd put in and the number of miles I'd covered. It came out at about 42.5mpg - much more like the old figure. I'm now wondering whether Citroen have just fouled up the software that works out the averages. Would be interested to know if anyone else has tried calculating their mpg by hand. Quote
hertsnminds Posted June 27, 2005 Posted June 27, 2005 I always note the trip and total miles at every fill up, also the amount of fuel I put in the car. I do a lot of motorway miles and the trip computer shows between 40mpg (heavy right foot) and 44mpg (70 mph cruising). The "real" readings are, after 13,142 miles I have put 342.1 Gallons in the tank which equals 38.42mpg. From about 40 litres of fuel I get between 350 and 400 miles, very roughly 10 miles for every litre. Each bar on the fuel gauge gives about 60 miles until the last bar which I estimate goes out when the are about 100 miles left in the tank. Ian Orange 03 Senso Quote
Richard Fairhurst Posted September 5, 2005 Author Posted September 5, 2005 Just got my best result yet from one tankful - 386 miles from 37.5 litres, works out at about 47mpg I think. The Pluriel (post-X12) is showing an average of 42.1mpg over this period, but what does it know? :( Quote
