Car Mechanics (UK) - - Electronic Diagnostics -

Our sec­ond fault man­i­fests it­self with the en­gine hes­i­tat­ing, ac­com­pa­nied by an in­crease in me­chan­i­cal noise and smok­ing from the ex­haust, to­gether with

il­lu­mi­na­tion of the oil level warn­ing lamp on the dash.

The prob­lem could be low pres­sure in the in­let man­i­fold, due to an en­gine ECU soft­ware gl­itch, re­sult­ing in ex­ces­sive oil con­sump­tion. How­ever, be­fore at­tribut­ing blame to the ECU soft­ware, a me­chan­i­cal and elec­tri­cal as­sess­ment should be car­ried out, to elim­i­nate other pos­si­bil­i­ties.

If no other prob­lems are un­earthed dur­ing this process, the ECU will have to be re­pro­grammed with up­graded soft­ware. Un­for­tu­nately, this task can only be car­ried out by a Nis­san dealer or a spe­cial­ist that has ac­cess to the ap­pro­pri­ate equip­ment.
