My EML is coming on when I am going up an incline and then Freelander goes into limp mode. Recently I have changed the turbocharger after the turbofilter blocked and turbo blew. After about a week or two of burning off the residual oil after the turbo change the light started to come on. What are the possible causes? I tried disconnecting the MAF sensor but the other yellow light Emissions came on permenant and went off after a day of driving with it reconnected.
