Right so for the past year of owning the car after my brother i've been getting poor MPG for ages, I only seem to get 400 to 430 miles to the tank which i've always been vex about.
So decided to take some action myself and try finding out what could be causing my 400 mile tanks as it was motorway journeys included which should really be better than 400 miles to the tank. I very wrongly self diagnosed my car to have a fooked MAF as the signs seemed correct but that wasn't the case as it made no difference at all.
So in July I had my regular service and a check over which showed that the pipe at the front end at the bottom waqs loose and coming undone so may have been a boost leak, also got the fuel filter changed and maybe not a good idea coming to think of it now but I got it mapped.
Car ran great for one tank only, I got like 530 miles to the tank mixed motorway but more inner city than motorway so was really pleased thinking i'd got everything sorted.
How wrong was I when straight after that tank I was back to exactly square one, 400 miles to the tank again mixed city and motorway more city than motorway.
Was advised on my service that the exhaust looked weak near the cat but didn't look like it was blowing, but a month later the cat give up the ghost and completly comes away making the car sound really nice kinda like a scooby
£155 new cat fitted.
Got car checked out and seemed as though the intercooler was leaking so got that replaced, I then got a boost leak at the top of the intercooler pipe connector the day afetr fitting the intercooler, it gave up the ghost and was leaking big time almost all come off, so for a connector pipe fits in place and a nice tight fit too. Good thing was that the intercooler came with a brand new MAP so that was eliminated from the possible problem also. Mechanic was top as he even offered to work Sunday for me to get the boost leak sorted but managed to get there for the Sat instead.
So there's me thinking this must be it, there can't be anything else wrong as i've changed a fair bit of stuff on the car and it should run sweet now.
Jeez one motorway journey and inner city driving, now i'm on 40mpg motorway and 31-33mpg max around city.
I've really given up on this car, it's really doing my head in and has totally drained me financially, chomped away at my wheels/mods fund and now my wage aswell.
I'm proper wounded and can't think of what else it could possible be.
Good job Guy Forks night is gone otherwise I would've blooming torched the fooker I was that angry. What is it with this bloody car.
Oh the beauty of this fooking machine is that it has never once shown a fault code ever even when i had a huge boost leak for a few days. Fooking doing my nut in.
What else could it be?
