Why would you overtake in 6th gear? That's called lugging the engine ya noobHi, I've had my car back for a few days after having the fuel pump and ECU replaced. The dealership was fantastic, they admitted it was a known fault, organised a courtesy car as it was going to take them nearly two weeks to get the parts and even said it wasn't the first time they'd done this replacement at their site.
Anyway, that aside, since I've got it back I can't say I'm overly happy. I've seen other posts saying there's no turbo boost but I can see my turbo boost light coming on and hear the turbo winding up so that's not a problem. But despite this it just seems to be lacking some guts. It is almost as if it's lost say 20 to 40 BHP. Don't get me wrong, it's still quick but lacks that aggression, that little something that makes you smile. I've noticed it more when I've been in 6th gear on the motorway doing 60/65 behind a lorry and put my foot down a bit for an overtake. I never used to consider coming out of 6th but now feel that 5th would be a better choice because 6th is just taking forever to pick up that extra 5-10mph. I've also noticed it's not absolutely smooth on tickover. Just now and again it's blipping a tiny amount which I'm sure it never used to do.
I was wondering if anyone else has had these issues?
And has anyone who's had the fuel pump / ECU replaced actually managed to get the car tested to see if it's still got all 270 ponies under the bonnet?
I'd also be interested to see the BHP and torque mappings on the old and new ECUs If anyone has got hold of them from Hyundai etc. Because I'm convinced the power delivery is noticeably different to how it was prior to the new ECU / fuel pump.
Not really, this engine pulls strong and smartly from 60 in 6th gear and you're not lugging it either.Why would you overtake in 6th gear? That's called lugging the engine ya noob
Lol. Typical. No black box telling them what to do, so can’t fix. Whatever happened to actual knowing one’s job?Took the car into the Hyundai garage this morning. With a cold start, it would not go faster than 100km/h on the highway, I was seriously concerned that I would not make it.
I then watched the car spluttering as the technician drove it in to the workshop. Just had a call saying that the computer doesn't have any fault codes, so they cannot do anything. Any further investigation without a fault code would not be covered under the warranty.
I just sent them a copy of the video that I made yesterday.
@Moritz do you have any links to forums where others have reported this issue?
Clever little thing. Interesting that they say you can still drive it but at low speeds. I’m not sure I’d be using it all.
Easy fix by the looks of it though. You’ll be desperate to get the car back in top shape Garth...
Please share where, or atleast post the recall. No one has seen it, obviously. Still haven't seen a TSB, as referenced in the op's thread title either?There is Now a recall for gen 2 N due the fuel pump
Hyundai rang me up on thuesday and asked me to bring the car in yesterday. Hyundai Belgium told them to change all four fuelinjectors (has apparently been done to another Belgian N before). I was a bit sceptic because the car started pretty good, only every now and then a slight hesitation, nothing special.Just ran in to my first problem with the N, resembles the highpressurepump issue a bit.
On tuesday, during a highwaytrip on cruisecontrol, the car started jerking. Went of the highway, but the car was hardly driveable at constant speeds. No lights on the dash and no error on the screen. Drove to the dealer and they found a faultcode: misfiring on cylinder 2. By then he was even misfiring on idle. Strangely enough the exhaustvalve went wide open, no matter what setting.
It was late allready, so the dealer tried to solve it by putting another ignitioncoil in from an N he had for sale. He gave me an apointment to bring the car in today. The other coil didn't help, symptoms stayed the same...
Didn't drive the car for two days and took it to the dealer this morning. The jerky drive was completely gone and the misfiring on idle was hardly noticeable. The exhaustvalve was behaving itself. When I put my foot down, the car accelerated but it hesitated twice in a full pull in third. On the performancediagram on the screen it only showed 240ish bhp, where it normally runs till 280.
The dealer told me they would have a look.
Got a call this afternoon that I could pick it up.
On collection the dealer told me it was misfiring on cylinder 1 and 2. They contacted Hyundai who told them to switch the coilpacks between 1,2 and 3,4 to see if that would help. Strange way of thinking when you know that changing the coilpack on cylinder 1 only made it misfire on 1 and 2 now.
Dealer told me to give it a try and come back if it wasn't fixed.
I drove of and was back in 10 minutes. On the first pull it was immediatly clear the problem was still there. Only difference is that it's less noticeable and the car is driveable now.
Dealer said he would contact Hyundai on monday and call me back. Told me I could keep on driving the car.
To resume: they haven't got a clue!
I'm thinking injectors or ecu.
Hope they get it solved quickly. Don't fancy driving around with a crippled car during the Christmasperiod (dealer is on vacation for two weeks).
N is a 05/2018 car, 46000km on the clock, no recalls needed, starts pretty good but sometimes a little hesitation.
This seems to be the consensus amongst those who have had to had the problem in both the VN andi30N. I hope and expect @Y0UKN0WITSCHRIS to horn in here. He had it done a month ago and it solved his problems.Hyundai rang me up on thuesday and asked me to bring the car in yesterday.

Picked the car up yesterday evening and did a 150 km drive. Everything seemed to be ok again: the jerky driving at constant speed was gone, no hesitations when making full pulls, only thing that was still a bit strange was the idle. The misfires were gone but it was hunting up and down a little bit. O, and strangly enough: the stop - start wouldn't work. Normally that takes not more than a second to engage or to show the orange light, now it kept thinking for about 10 seconds and than showed the orange light every time. I took the car for a drive for work today of about 120 km and every time I stopped, the time the car needed to engage start-stop got shorter (and engaged) and idle became more stable.
After a while I must say everything is back to normal: normal power, smooth driving at constant speed, no hesitation, ...
Must be somekind of selflearning mechanism in the ecu.
So for me 4 new injectors seem to have done the trick.
Great service from the dealer also: they rang me up around noon today to ask me if everything was ok now because they were closing for two weeks and so I could still get a courtesy car if needed.
