      Posting in General Chat thread.   11/11/2017

      it has been noted that too many Members are posting messages in the General Chat area instead of the correct Forums. Any messages posted in the General Chat area that are not General Chat will be deleted without warning and offenders may recieve warning points if repeated instances are seen from that Member. There are plenty of different Club areas that encompass 99% of Ford related posts, please select and use the correct one. If anyone is not sure of which area to post something then feel free to P/M myself or other Senior Staff for guidance. The Moderating Staff are having to spend far too much time chasing this problem instead of maintaining the other areas of the forum.

    c-max 1.6tdci 57 plate
  1. C- Max MPG

    Been investigating poor mpg in the c-max for a few weeks now. A lot of people seem to be having the same problems. I average ( in a 1.6 tdci 57 plate) around 43mpg going to work and back (20 mile on a-roads), with the maximum of 50mpg on a motorway at 60 mph . Frankly, I am very dissappoined, especially when comparing with the quoted combined average of 57 mpg from ford, and comparing against my previous diesels :- Rav4 2.0 ltr average 39mpg (4 wheel drive and heavy) , motorway 47mpg Toyota auris sr180 2.2 diesel average 47mpg motorway 56mpg Skoda vrs diesel 170 bhp estate average 47mpg , motorway 58mpg civic 2.2 diesel, average 52mpg, motorway 60+ mpg You can see from these figures, that my previous diesels have been much bigger and faster cars, yet have returned much better economy. I have checked :- 1. the ECU fault codes, none exist. got a lead from ebay. 2. any leaking air inlet pipes, especially the large one across the front of the engine, all air tight. quick check is to open the air filter box and block the air inlet pipe at the MAF sensorto see if you can stall the car and watch all the pipes collapse under suction. 3. cleaned the MAF sensor. I am now going to see the ford dealer to see if there is an ECU update. I would also be interested in anyone else with the same engine and an OBD lead to see what air flow, air temp, oxygen sensor, rpm and fuel pressure they have at IDLE, 2000 and 4000 rpm for comparison. any other ideas would also be welcome. Surely a 1.6 turbo diesel should be much better than 45 mpg. I am tempted to buy a diesel chip for better economy, but want to see if there is a faulty sensor or ecu first........
