Rather inconsistent innit ?
Just had all four glowplugs replaced by renault as I reported bad return on fuel economy and one showed up on diagnostic as fault .
Waiting to see if its made much difference will report later on results
Why should the glow plugs have anything to do with economy? This is not a very professional response to your problem.
It may well be that there was a faulty glow plug but yours is a compression ignition engine and the glow plugs are not spark plugs in a petrol engine. I would not expect to see a difference in mpg on that. More probable would have been a reprogramming of the injection system. Was this mentioned?
