Hope this is allowed but was a former MK5 Polo Owner
Stayed within VAG group have a 2019 1.5 Leon FR EA211 doles any know if this has a particle filter?
Have really bad MPG and don’t understand why as have had major serviceZ
The articles at the links below suggest your car will have a GPF as VAG stated back in 2016 that they would be fitting Gasoline Particulate Filters to all direct injection petrol TSI and TFSI engines from 2017.

As for your mpg; it’s only during the forced GPF regeneration process that the fuel consumption suffers compared to the ‘normal’ mpg as additional fuel is used to help burn off accumulated soot in the particulate filter during the regeneration. Based on my personal experience, a forced regeneration with my VW takes around 30 minutes to complete. Therefore, if you’re experiencing a general deterioration in mpg then it’s likely to be due to other factors, especially if your car’s not displaying any other the other symptoms that indicate a forced regeneration is taking place;
- are you relying on the car’s fuel computer for your fuel consumption figures or are you calculating your mpg manually? If the former, it would be worth calculating it manually over a few months.
- have you switched fuel brands?
- has your mix journey type changed? e.g. are you doing more short journeys at peak times and fewer longer journeys?
- are you driving more short journeys on cold engine than you were previously?
- do other drivers use your car? If so, are they driving it more frequently than previously?
- are your tyres at the correct pressure?
- have you recently changed your tyres to a different brand with a poorer fuel economy rating?
- I’ve read that in addition to there being summer and winter blends of diesel, there are also summer and winter blends of petrol. Winter blend fuels are usually sold from mid November to mid March. With diesel, using winter blend fuel results in poorer mpg; maybe the same is also the case with winter petrol?
Hey thanks for getting back to me, appreciate it.
Hmm not sure then, I’ve had the car around 6 months now and experienced relatively underwelming/poor MPG from day one. Should’ve just returned but thought I’d see it through thinking it’s because I’ve got a new car that may have been sat undriven for months, just need some time to break in.
I’ve calculated manually here and there not consistently admittedly, didn’t seem too different to what the computer was reading. But started to track again tank to tank using an app last week. So will have to wait and see.
I’ve tried different fuel brands Tesco Momentum, Supermarket, Costco etc. Doesn’t seem to much in it for difference tbh.
Probably getting on average 320ish miles from a full tank and according to the trip computer that I’ve reset previously, my average over last 2000miles is about 28MPg.
I’ve seen people with Cupras get better.
My journeys have been a mixture of short and long journeys, but I do like to take my car down the motorway every so often when I’m mainly doing short. To give it a run and to see what I can squeeze out of it
Nobody else drives my car just me
Tyres have been the same since I bought it maybe something I should look into not sure of the brand will check tomorrow
I know typically fuel economy worsens in winter but can’t figure out why mines so bad when I check owner groups and people with the same model easily seeing 40+ and I’m struggling to get low 30s even on a long run.
Thought a major service might have done the trick but nothings changed, car does seem a bit smoother but fuel wise nah
What’s the best way to force a regen? Just so I can at least rule that out.
Took from screenshots last week from OBDeleven live data on engine block, after seeing this thread, not sure if it means much. Not exactly sure what I’m looking for and was taken shortly after starting car hadn’t driven it.
Been to a Main dealer about this fuel economy issue but seems they won’t investigate if they don’t see any fault codes which is annoying.
Definitely something wrong here what it is I don’t know.
