CRDi is one of the greatest improvement in Diesel Engine Technology....Although the technology is a bit pricey but you can equate that to the performance and efficiency of the engine...
Many are in doubt of CRDi technology, this is the same when the EFI engine was introduced replacing Carb engines... at first we encounter troubles and ECU problems which we thought at first cannot be solved by ordinary mechanics.. but now EFI engines can be diagnosed and repaired...Even the unrepairable ECU, now can be repaired
Having a vehicle equipped with a CRDi engine is just like upgrading your HEADLIGHTS from HALOGEN bulbs to HID bulbs... Although HID Bulbs are expensive to purchase and maintain, still it is very efficient, low power consumption compared to Halogen
