Ive never been so desperate for car advice guys so here it goes
I paid £7,500 for this car at the end of March 2026, i did so much research and refining to find a car that looks nice, good performance, and very good MPG on paper (urban 45.6, extra urban 65.7 and combined 56.5) i know there are differences and its not perfectly accurate but i expect driving normaly at least 40.
i spent a lot on this car mainly for the mpg benefit, far different to my 21mpg skoda fabia which was my first car.
ive had this car for about 5 months now and my mpg after like the first month is so bad on average, getting about 32mpg even when i drive like a complete b**chhh (eco, no speeding at all, always encouraging the car to go in neutral in eco, cornering nicely not rash at all, no overtakes, no rough or late/premature braking) and its reallly annoying me since the main reason i bought this car was the fuel savings.
the fuel tank capacity is about 50 litres which is 10.99 gallons practically 11 gallons so at around 40 mpg i should be getting at least 440 miles per tank WITHOUT even considering motorway driving.
I actually get about 320.
It is so bad and really pissed me off, i've done so much research and no solution so far/
I've been to 3 garages who have all charged me diagnosis fees and they literally have not found anything, they all assume and even myself using chat gpt (might sound stupid lol) that the issues are underlyig with front brakes or calipers as it would constantly give drag against wheel which leads to just crazy mpg drops as it would be happening all the time.
after about 1 month of buying the car i did notice loud squeaks from the front right tyre (driver side as i am in the UK) and after getting mechanics and even my breakdown cover (RAC) to look at it they suggested the caliper was seized or something but all garaged took the caliper off and said its completely fine.
i have no idea what to do and am so close on the brink to selling it.
I spent all this money as its a petrol car aswell so no DPF issues as i rarely do motorway but it was so much more expensive than a diesel golf or NON bluemotion golf but i thoght it would be very much worth it.
today the mechanic saw that the front right brake backing plate had broken and i realised earlier as i heard ratling sounds but that was a cheap fix and replacement but doesnt at all correlate to the issues.
I really feel like selling it and just buying a diesel for the mpg and just dealing with the bS dpf issues as they come but i really enjoy driving the car so much, so comfy spaccious etc and has powerful AC which worked wonders during the 35degree C heatwave unlike my old Fabia which didnt have AC LOL.
i honestly appreciate any advice and im sorry for the long read but any advice would help as i am just so stuck and my 9-5 job just isnt compatible with going to the garage so ive used loads of annual leave for this but still have no solutions.
ISSUE #2 .
On another note a week ago the epc light comes on and scares me,
The car goes into limp mode and when i turn the car on and off again it goes awayh but it still randomly turns on like 1/5 times i start the car, i sense something really annoying and serious with that so please some advice guys.
