overfuelling diesel

[JohnAllen]

hi all, problem is this. My ZT diesel (06) has covered 135K. I bought it 2 years ago at 118K. At this time I was getting 42ish round town and up to 65 on motorway. Recently its dropped to 34 round town and I'm lucky to get 50 on a run. Just had full clutch done as it had started slipping and I thought that might be the reason for low mpg. Car was mapped as soon as I got it and up to 3 months ago mpg was great. I don't know where to start, help!!!!!!!

Check for any hot wheels due to brake binding as we had a similar problem on our Tourer a month or so ago,cause was a seized brake caliper.Hope this assists.

Worth checking the thermostat isn't stuck, as this has a huge detrimental effect of fuel consumption.
Do a search on how to access the temperature readout on the IPK, and let us know the outcome.
Failing that, pop over to see BigRuss in Liversedge, and I'm sure he'd be more than happy to T4 your car.
Best of luck
