[marti30]

I took my previous diesel i30 from new to 288,000 miles and traded it in under Hyundai's 'scrappage' scheme when the engine oil migrated to the coolant. Although not all trade-ins were destined for the breaker under this promotion I thought mine was due to its age, mileage and major fault of which the dealer was well aware.
So imagine my surprise when I checked the UK government website and saw that according to its MoT test (statutory safety and emissions examination) history it is now a 57,000 mile petrol car. Strangely, according to the vehicle excise duty part of the website it is still taxed at the lower diesel rate.
Actually converting a modern car from diesel to petrol must be a monumental task requiring the replacement of many components as well as the engine and gearbox.
Can anyone suggest an explanation?

Possible mistake in the government listing someone might have also had a petrol model with a damaged body and threw everything into the diesel

Reg transferred to another vehicle....?[

Actually on reflection I think its more likely they just dropped a petrol in to it.

Maybe the rebirthing industry is alive and well.

Yep 

I know Marti sees this as a daunting task; not so! 
Using a low mileage writeoff as donor, I would drop the sub frame complete and therefore swap the whole drive train into the good body. Then the ECU etc.
Roughly, a 2 day job for one person.
