Today I was finally able to go work in the garage. I got the new filter assembly (part 31911D) couple of days ago. New filter and new sensors and heaters etc. were allready assembled. 272 from this was still quite over priced in my opinion...



I changed the filter couple of weeks ago, so this was quick and easy job. And now didn't even have to remove the filter from the assembly. Took only about 30min. Here's old vs new.



Bleeded the system and there it sits. Cleanest part in my car  :D



Started engine and no leaks or warning lights so everything is OK, for now. I did a 20km test run and everything worked well. Now I gotta keep fingers crossed and hope that the limp mode does not come back.

Little bit of offtopic:

I must say that Hyundai parts are not the cheapest ones around. When I picked up the parts from local Hyundai dealer I asked if they had those micro relays for horn (and fuel pump etc.) I broke before. They didn't have them right now, but they could have ordered one for me. When I heard the price,  I started laughing. So did the salesperson. They would charge 40 from a 4-pin micro relay with a Hyundai logo on it. Never thought they had such a ridiculous prices... Only thing with the relays is that the Hyundai relays are about 1mm smaller than "universal" micro relays. And in the fuse box there are these plastic "covers" to prevent using normal sized relays. So I used dremel to grind plastic relay "covers" in the fuse box and fitted normal universal relay. That relay costed only 2.9. Now I have a working horn again. Gotta love Hyundai pricing...

Here on the left is the original, which should be solid gold based on the price tag. On the right is the 2.9 relay which works as well as the original.

Hi

Next time you need parts that don't have to be urgent, buy them from Korea.

You can get that filter assembly for 97 USD / 78 EUR...

:link: KORAPS - KORea Auto Parts Service - HYUNDAI KIA GM SSANGYONG RENAULT Genuine Parts! Low Price!

I got a washer pump and an ABS sensor from there, took 3-4 weeks to arrive, but came in original Hyundai boxes... :mrgreen:

I paid ca 95 EUR at Koraps.com for what my local Hyundai dealer wanted ca 300 EUR.. :scared:

Thanks for the tip. I thought that there might be some place where you can get cheaper parts but never found one.

Damn... I wish I had known about that KORAPS place. I could have waited couple of weeks more to save almost 200.

Quick update: It has been one month since I changed the filter assebly. There has been no limp modes after the repair. I haven't driven so much, only about 1000km, but car works fine now. I hope it stays this way...

Here again... unfortunately.

Car worked fine until now. It was time to make small service for the car before the winter. I changed the fuel filter and did not use oem part. It was manufactured by AMC if I remember correctly. The car worked fine, but in the last week I had to crank it few seconds longer before it started and the acceleration was little bit jumpy couple of times. I drove about 1000km with the ACM filter. Today the car went to the limp mode in the morning traffic. No check engine light, only powerloss. I restarted the car in the next red lights and drove to work without any problems. Strangely I was able to read the codes in the parking lot even I had restarted the car. That did not happen previously. I got two P1186 codes, so it was again about the low fuel rail pressure...

Went to the dealer after work and got overpriced OEM fuel filter. I got just back from the garage & test drive. It seemed to work, but I think next couple of weeks will tell the truth. I am starting to get some regrets for buying this car...

Sad that you feel this way, as you may have read, my i30 gave LHM problems for over 2 years, but during that time I still really liked the car, and there is the rub; you may have to make that final decision, please don't ignore alternative manufacturers problems (that are so well publised) 😉

I assume that if the low fuel rail pressure was cured, you would be much happier with the car. Why not get it seen to professionally instead of trying to take short cuts with non oem parts.

It is unfair to blame the car if the ACM filter is the cause as YOU supplied the part. Also be aware that there just may be a small air leak into the system caused by the actual filter canister. I would look to replace that as well, just to be on the safe side.

When I previously had limp mode issues and I took the car to the dealer, they did not know what caused them. They weren't even able to get the error codes out of the car. I had a discussion with them and we thought together what might be the issuel. Therefore I am not paying to the "professionals" about something that I can do by myself.

I don't know about your country but here getting OEM parts for hyundai in here is not the easiest thing. Especially if you need them ASAP. One time I had to wait 4 days to get fuel filter from the local HY dealer... Third party parts are available much more easily and you can get them from almost every spare parts store. It looks like I have to order larger amount of filters and other normal service parts from Korea so that I would have a small stock of OEM parts in the garage.

I knew there might be a small risk with non OEM filter based on what I have read about these problems. I did not expect it to be this bad (if that was the cause). I've heard and have had issues with bad filters, broken filter assemblies, leaking fuel lines etc... In my opinion the fuel system is just badly engineered if there are so many (and fairly common) problems. I never had any issues with non OEM parts with other cars I've serviced (even in a Hyundai Getz).

I checked all the fuel line connectors and they seemed to be in fairly good condition. I think there has been couple cases in this forum where the quick connectors have been leaking and letting air in to the fuel system. I wonder why they have used those quick connectors in the fuel line. They seem to be little flimsy in general. Just a normal hose with a normal hose clamp would have been much more cheaper and much more reliable solution.

Time will tell if the problem is solved. If the limp mode does not occur in the next year or so, then we can blame the non OEM filter.

OEM parts are generally available on Ebay, but you do have to look around for the best price.

Keep us posted on the outcome, sorry the "professionals" were unable to help you.

To be fair, there are also good mechanics. I understand that it is difficult to fix something if you can't see the symptons or get actual fault code. Also you rarely actually fix something in these modern cars. There are electronics and other stuff in the parts which makes them hard to fix. It is easier to replace the whole part, which gets expensive...

Lucky for me we have lot of true professionals & enthusiasts here in this forum  :D. I've saved a crapload of money using their tips and advices.

Just a quick update. It has been almost one month since I installed the OEM fuel filter. Car has worked flawlessy since that.

I still had the original  OEM fuel filter in the garage from the time I had limp modes first time. Finally got some motivation to check it with endoscope. There were some small black crap inside the filter. Har to tell if it was from fuel or was it just dust from the air. The old filter was on the floor all this time... The most recent filter (non OEM) was clean from the inside, so it seems that the actual filter material was the cause for surging acceleration and limp modes.

I know people whos "food route" has been checked with one of those. According to them "input" checks were worse than "output". Said to be one of the most unpleasent things when you need to swallow the tubes...

I actually had no problem in the private system as I was properly sedated at the time.
I do know people, however, who had it done in the public hospital system in Australia and it was less than pleasant due to to skimping on the required drugs.
My specialist told me to only ever have it done within the private health care system (in Australia).

Hi Mike, im experiencing the exact symptoms that you had. Mine is a 1.4 petrol 2014, Just wanted to know did replacing the wiring loom resolve the issue at the end? Was that the main fault?

No problems since the loom was replaced.
It was the only problem causing Limp Home Mode.

With the codes logged, it should be a simple fix....
My long term (finally solved) problems were created not only by the selling Main Dealer incorrectly fitting a cruise control unit to my model, but by their continual ineptness.

Hi Mike,

I had an issue with a fuse that serviced the camshaft position sensor.

The check engine light/limp mode would cone on and off periodically but under no specific circumstances. It may be worth checking all your fuses under the bonnet, particularly anything that services the powertrain.
