I bought my 2.2 Diesel from a main Mazda dealer last September with 69,000 mileage & a 12 month warranty,on 2 occasions earlier this year the EML & DPF warning lights have come on,it was taken back to the garage who did a regen to clear the fault codes & although they said it was a maintenance problem (at my expense)they fixed it on both occasions free as a goodwill gesture.
I now have a mileage of 80,000 and the engine sounds like a tank with 800 rpm at tickover,it is back with the garage who say it probably needs a new engine & the warranty may not cover it
so I should enquire about costs to replace it myself but surely the 'mechanical failure' element of the warranty covers the cost of supplying & fitting of a replacement new/recon engine?
