Having had a Santa Fe from 2011 to 2015, in 2015 I helped my daughter-in-law choose and buy a late 2014 i30 1.4 petrol manual. It was serviced at 1, 2, 3 & 4 years by the selling Hyundai dealer under their service plan - no detailed invoice with parts listed was provided. Since then it's been serviced at 6, 7, 8 & 9 years by our local trusted independent who we've used for 30 years for all our family cars - detailed invoices were provided.

I've not been involved with the car over the 9 years as it has run faultlessly, until now. The engine management light came on intermittently then permanently. I've done a scan with Gendan Engine Check and it shows P0301, misfire on cylinder 1.

When I checked the service records, I found that none of the services have had any additional work beyond oil/filter change so at 105,000 miles my first stop is to replace the, presumably, original spark plugs and run some Redex through the fuel system. If that doesn't cure it, I'll replace the coil pack for that cylinder - when I'm doing the plugs I'll switch the coil packs between cylinder 1 & 2 to make diagnosis easier.

My reason for posting is to find out what additional tasks should be done at what interval, specifically :-
Spark Plugs
Air Filter
Cabin Filter
Fuel Filter
Engine Coolant
Manual Gearbox Oil
Power Steering Fluid
Anything I've missed

Your help will be much appreciated

I have a Hyundai service sheet for petrol/diesel engines on the 2-year/20,000 mile service interval. It reads as follows. If your car is on a 1-year/20,000 mile service interval I think the only difference is that engine oil & filter change interval is 20.000 mile or 1 year. Personally, I change mine at 10,000 mile or 1 year, whichever comes first.

Spark Plugs    Replace at 40,000 miles or 4 years
Air Filter          Replace at 20,000 miles or 2 years
Cabin Filter     Replace at 20,000 miles or 2 years
Fuel Filter        Replace at 60,000 miles or 6 years
Engine Coolant             Replace at 60,000 miles or 6 years
Manual Gearbox Oil     Replace at 60,000 miles or 6 years
Power Steering Fluid    Doesn't have any, power steering is electric, unless you can see a power steering fluid reservoir

Brake & clutch fluid       Replace at 20,000 miles or 2 years
Engine oil & filter           Replace at 20,000 miles or 2 years, (I replace mine at 10,000 miles/1 year interval)
