Can I retrofit a petrol engine into my diesel car to be compliant with the ULEZ?

I'm happy to keep my Freelander 2 TD4 until the end of days. Is there any option, anywhere, of an engine swap to petrol and could it be legally re-registered to cover ULEZ? I daren't even ask about insurance.

I think it would be cheaper and quicker to simply sell the car and replace it with a petrol Freelander 2. The conversion costs would be huge and your insurance premiums would go up as it'll be considered a major modification. There is also no guarantee that, after spending £1000s on the conversion, TfL would recognise the changes and provide an exemption from the ULEZ.

Will you have to pay the low emissions charge?

Use our ULEZ checker to find out if your vehicle is subject to ULEZ charges. Simply enter your number plate into the Honest John ULEZ checker to see if you will have to pay to enter the London Ultra Low Emission Zone.
