Hey all,
Been lurking the forum since before my purchase, I've picked up a second hand i30cw diesel auto. It's the elite/slx model so the interior is nice and in good condition.

My question is about under the hood though.

It's an ex taxi, and with a bit over 115,000km it was used as a secondary vehicle rather than being pushed hard all its life, otherwise would have much higher kms in that.  The servicing I'm more wary of though, as it's lacking service history.

I had an AA pre purchase inspection done which is fairly standard. Here's the overview. The rest of the report notes the tyres are good, engine compression good, and road test good.



I've had a flap actuator replaced in the aircon system to fix a known fault with it. The aircon specialist advised that the condenser is due for a service but isn't urgent.

The air filter was due for a change so was just swapped out with a standard one (looks similar to Ryco), nothing special like K&N.
The oil was just changed with some Havoline synthetic 5w-40 and oil filter changed. Noted a very minor leak in one of the left axles which they said wasn't a major concern, just to watch it.
The transmission fluid is in terrible condition, a dark grey going into black, so that's going to be changed shortly.

I'm going to be taking it in for a full check once I get the known issues fixed, however is there anything in particular I should be looking for on this vehicle? Overall I've had comments that it's in good condition overall especially for its age.

I am unsure whether the previous owner stuck to the set service intervals, I doubt that they did. So it's likely due for some inspections.

However ideally would like to find a mechanic that isn't the Hyundai dealership but knows the vehicles, still working on that. The Hyundai dealership wants a lot of money for a standard service not even including parts, so I'd like to avoid them unless I really have to.

Okay - I am not a diesel i30 expert... so there might be none - if so totally ignore this :-)

If you are unsure about service intervals and/or proper servicing having been done - replace any belts unless you and/or experts can tell they are 'new'.  Esp. if valve timings rely on it - BUT I don't think this is the case for the diesel though.

I expect the schedule probably wasn't adhered to officially - because a) usually vehicles for commercial purposes get reduced or limited warranties (compared to private); and b) combined with service costs from dealers, etc. wouldn't make it worth it.  Having said that if it was with one of the bigger firms - it probably got services via. their garage facilities (if they have them or a company that does all their work) which shouldn't be shoddy at, due to the nature of their work.

Hi eXDee & 
Most important thing with Diesel is changing Fuel Filter about every 30,000 as dirt will wear injectors & injector replacement big $'s. as you would be out of warranty no need to use genuine Hy filter ( rip off price ) try to buy Ryco or similar trusted make also note there are two different type fuel filters early type i think was till about May 08 & earlier, the Hyundai parts used to ask me to see rego so they could see Vin # but i would expect later type filter more common now. and CW all came out after 09? also has been noted a few Auto trans have given problems. & as you stated the trans fluid was dirty but by the sound of it this car has had a good operator & i would expect driven carefully all its life. But as the 1.6 has 260 nm Torque from low rev & a flat broad Torque curve 1,900rpm to 3,200rpm all at 260nm. the auto would get hot easy if you excellerated a lot, so my advice would be fit a trans cooler & hook it up as stand alone not joined in with radiator & you should have no worries with the trans. i think good idea to change oil at 7,500k. it's is not a hard car to service at all. to change fuel filter they remove filter housing off fire wall two 10mm think need a deep socket, then replace fuel filter on bench then re fit to fire wall prime fuel with button on top of filter the oil filter is at top front of motor they use a replacement element . any reputable wrench could do the job.
good luck with it.

Hi exDee and welcome. You seem to be on the ball and have gone in with your eyes wide open. A trans cooler would be nice, but might be hard to justify unless you do a lot of towing, but I would get that transmission fluid changed out asap. Signs of an auto transmission problem are delays when selecting reverse and first taking off.

Fuel filter, will get that looked into. The air filter and oil filter however are done. I see a ryco fuel filter is about $60 from supercheap.

Transmission cooler, i had a google and I can't find anyone specifically doing this with the i30 FD. Can you elaborate? i lack a towbar/hitch btw so not smashing it, but I don't want transmission issues. Is this common practice?

I'm getting the transmission fluid changed this weekend.

Checking the odo more precisely, it's now clocked 117,000. I'm tempted to take it to Hyundai just once for a full check over. But i know it's going to cost heaps, especially for any parts that need swapping that i could have got elsewhere. So i'm wondering if i can reduce the service cost by getting the obvious replacements sorted first.

Thanks all, useful info.

A transmission cooler on the i30 isn't common practice as far as I'm aware.

there was a mentioning of a guy who didn't change his fuel filter for over 200 k km. Not saying its a good practice but I think it mostly depends on the dirtiness of the tanks in the gas stations.

I wonder if anyone has disassembled the fuel filter after replacement, to see how it looks.
I wanted to do that with mine, but I made the last call to change it at the dealer - so didn't have much chance to taki the old one with me (for disassembling)

Also, mine 1.6 Crdi has max torque 235 Nm at 1750-2500, 66kW

From memory the original i30 diesels had a 60k change on the filters, but Hyundai dropped it back to 30.

$60 for the diesel filter is a rip off....
