2017 superb estate 2lt diesel manual  sel exec estate. with only 52000 miles. Car has had very little use in last year. Was struggling to start. Originally thought battery of about 4yrs was done. managed to jump start of battery pack.

Engine warning light came on. Took car to garage, who said battery was fine and lights probably just down to the jump start, lights deactivated.

Was cleaning car next day as about to sell trade it in , so had radio playing for about 2hrs, battery totally drained so decided garage was wrong and bought new battery.

fitted new battery and car starts better than before but still with slight hesitation.

Plug in OBD Veepeak and is giving me the following codes. i can cancel and they will stay off for a day of stop start driving but eventually come back.

 

PO684 = i believe to be glow plugs and or control unit. General advice would be to change 4 plugs and unit at same time. any thoughts otherwise ?

04976 = unsure this could be many sensor type faults but also read about bad oil and filter ? car was only serviced 6 month ago ? any thoughts ?

00012 5f = no idea about this one ?

 

 

 

 

All sorted, further investigation showed both codes pointed towards a faulty glow plug relay control switch. Not a major issue but would appear to be quite common.

Superb now traded away for a brand new Octavia 4 SE L HB 1.5p, still to be built in factory due in 16wk. Ordered and paid for pre face lift but fingers crossed 

could be right on the cusp of the change over.
