Hi All,
Figure this should be the next thing to tackle as it is becoming rather grim, got 280miles out of 30liters last fill, on sport rims but still.
I've picked up filters for intake and oil etc. and will give it a quick oil change and service however i doubt that'll sort it.
No lights nor did i have any codes - will get vcds set up at some point to have a play.
I strongly suspect a leaking intercooler - will probably take hoses off plug one end and try to use a ball inflator or something to test it to avoid taking the bumper off as ideally i'd like to leave it for when i have a replacement bumper to replace it with. It smoke a bit if i put foot down and it need to build up boost from nothing, 2nd for example, sometimes takes up to 3k rpm for it to start pulling properly with it noticeably smoking a fair bit out the back end until it gets there starting at about 2k rpm.
DIS is fairly accurate i noticed over the time I've driven it being within a few mpg - reporting 36 this fill up. i do leave it for 5-10min to warm up now as it is fairly chilly overnight but wouldn't expect it to drop average too badly.
Tried injector cleaner which apparently made it worse (that or the cold weather)? Tyre pressure are fine and brakes aren't sticking (at least not on stilts), bearings do not seem to be complaining either, putting back together the gearbox there didn't seem to be what felt like excessive resistance for wheels turning/gearbox etc. nothing seems to be seizing up or putting up resistance mechanically.
Gearbox oil is fresh and with new dmf/clutch there aren't any odd sounds.
I'll record the car running, there is a bit of an odd noise, kind of like those shakers with rice in them from engine bay and when it is raining a lot it sounds like a slight belt slip but other than that it I've not caught any funny sounds. It does still vibrate a bit too much when pulling away in 1st without giving it some go pedal but i reckon it'll just be engine mounts as they do look like 150k miles later.
What would be the easiest things to start with checking, doubt doing the service of oil/filters will sort it as it has been not great on economy since i got it but it does appear to be becoming worse - wouldn't expect fuel additive to decrease mpg to any significant amount.
