2018 Audi Q5 TDI or TFSI

[Njsupplies]

Hi, I am looking to buy a 2018 plate Audi Q5. I have seen a nice spec and good mileage one but it is a 2.0 TFSI. Are the petrol ones reliable? Does anyone know the real efficiency of these compared to the diesels? although I only do about 7/8000 miles a year and generally shortish journeys so not bothered about trying to get very high mpg, but don't want a guzzler either.

Is there anything about these I need to be aware of, any big faults or issues with the TFSI over the diesel?

Any advice would be greatly appreciated

Thanks
