Hi All , I have a 2016 I30 Turbo , I have got a hesitation and holding back between 3200 rpm and about 4500rpm . The holing back is very noticeable in 3rd , 4th and 5th gear .
This is when the accelerator is being applied from 3/4 to nearly full pedal , if you push down fully ( burry in carpet ) this clears .
Worst is when going up a steep hill because it takes longer ( being going up hill) to run through between 3200 and 4500 rpm . Car has been to dealer twice but to little avail , they just plug in and no fault found !!!! Oh and it has latest software map installed .
Anybody else had this ? , thinking its a fueling issue caused possible by TPS not playing ball ???
Am awaiting Hyundai Technical for some support .

Hi Neil,

 

Sorry to hear of your issue. Very frustrating and disappointing when they show the "no fault found" card.. 

You may need to be patient with support for two reasons.

Our two "official" technical support volunteers are based in Australia where the 1.6 Turbo GD model was never released.

Also your model (even in the UK) is relatively scarce so we have only had a handful of members join with that model.

I recall one or two with your model askinging for help though so hopefully it was a similar issue and was sorted. I'll see if I can find any threads. Although that can be hard sometimes on an active forum like this.   

Edit: Did a fairly thorough search without any luck. I'm guessing it is basically the same motor as my PD SR and the Elantra Turbo so others may have some suggestions.

I would be starting to jump up and down if I were you and insisting on a technician taking it for a test drive with you as a passenger. Failing that, contact Hyundai UK to vent your disappointment.

Dazzler , cheers for reply , I live in hope .
I have been out of the motor industry for several years , but did finish my stint with Ford Technical so have a few ideas .
It can be frustrating when you appear to have more knowledge than the ones working on your car .
All else fails I will break out my tools .

I know how you feel. We have had 4 x i30's and each time we have bought one I have known more than the salesman. 

Hopefully someone will pipe up with some ideas soon. Our members aren't usually this shy!

Car Booked into dealer again recommendation  of Technical via customer care . I just hope this time they will actually look into correctly .
Was just wondering if anybody these days can look at live data and read it correctly to establish where fault lies .
My Gut feeling is this is a fueling issue caused by sensor slightly out of spec ( but not enough to generate fault ) like TPS or MAP/MAF , or just the whole ECU map is really not correct .
I will live in hope they can fix it as I surely wont live with it .

There is a starting issue with some Series 3 i30's and they have been using a data logger on some faulty cars but ironically it doesn't have a back up battery so shuts down temporarily during (attempted) startup! 

If your service centre had something like that it wouldn't be an issue for your fault though.

Hi Neil,
 Dazz has covered the issue of your model not being available here; but unfortunately, we do share the same level of dealer ineptitude and deliberate avoidance of seemingly complex faults.
Both insisting on an accompanied test drive and use of a data logger should convince the technical department that you have a fault.
Then the hard part - as you say, to find someone who can read the data.
It will be helpful if you can give us a heads up on the results.
I will do the same if I find something relevant.
Cheers Gary

[Dazzler]

Can any other members have a look for any problem threads on GD Turbo please. Someone may be better than me at finding something. I do recall someone having an issue with one before. 

[neilplumb]

Hi Gary , I hold little hope of them fixing it , am not saying that they are clueless but technicians are not trained as well these days .
I am contemplating buying some EOBD software tat will allow me to data log myself as I can read data and pin point problem area .
Essentially I would be doing the Hyundai technical job , perhaps they will offer a job LOL .

Will keep all posted on the developments .

We use that one in Australia too.. 

[neilplumb]

Sorry for delay , but here is the latest update .
Back in Hyundai dealer ( 3rd time ) they had to wait for special data logger from technical support UK .
They have done extensive road test where they have identified the issue . Technical have indicated they think the issue if around the Turbo or control of turbo!!!
Unfortunately the day before the car went to deal it also started to develop clutch judder , not impressed with only 20,000 miles on her .
Popped into dealer after a week , nothing done yet waiting for technical to get back to them , Really miffed why they haven't got on with the clutch judder yet .

I will update this when I have more news , if they cant fix I will back the car .

[Dazzler]

Thanks for the update, you need an award for you patience with the dealer.

The verdict that it is probably turbo related does not surprise me. But as you indicate," they think the issue if around the Turbo or control of turbo", is a pretty broad brush statement!

The clutch judder could be flywheel related. On many high power cars it is common to use a dual mass flywheel, they are 'spring loaded' to smooth the impact of the motor.

Quick EDIT: On small bore cars, Hyundai have used a hydraulic damper on the clutch fluid instead of dual mass.

Having worked for Ford, you would have a lot of experience at logging faults. At least the engine does not catch fire 

It is disapointing when a dealer fobs you off, through lack of knowledge or desire to fix a problem. Mine seems to want me to take the Manager for a drive to identify the fault, which usually happens after the 'tested no fault found' on a service.

Would be interesting to know what percentage of their product are written off in accidents over the 5 year period.

It sounds to me that the Electronic Boost Control Solenoid or the Blow Off Valve Solenoid are not operating correctly at part throttle.

Hence why you are getting full boost when you put your foot down..   Both are known to be not that great & in testing have shown to loose boost.

Hi All

Update is that technical have advised to fit new turbo , after this they will look into clutch judder .
Oh well just sit and wait as been in loan car for 3 weeks now so keeping mileage down on mine .

Thanks for the update.  Well that's positive news. A step in the right direction. 

[nzenigma]

 

Thanks mate. Turbo causing the problem  . But, if it does the trick great, will lock it in as a remedy.

[neilplumb]

Update is...…
Hope to get car back today ( been in garage 3 weeks +) its had new turbo , the have also fitted new clutch as they confirmed clutch judder .
I will post on how she drives in next few days , got my fingers crossed .

Wow! They've thrown big money at her! Well done! Good luck! 

[neilplumb]

Update , after the long wait guess what?...……… not fixed
Still got the hesitation/holding back between 3000 -4200 rpm on firm acceleration , I am convinced this is an ECU mapping issue .
Only plus is they have fixed clutch judder by fitting new clutch .
I am tempted to get the car on a rolling road and then show technical the data .

Very unhappy and doesn't give me confidence to upgrade next year to the N30 .

[Dazzler]

  Sorry we haven't been much help. Not a lot of exposure to your fairly limited edition version on the site.

The N is a completely different platform/series and motor. (virtually new from the ground up) 

[nzenigma]

Not trying to be smart ass but...

Turbo causing the problem  . But, if it does the trick great, will lock it in as a remedy.

Took 3 weeks  ???    Even in Britain, you could fit a turbo AND the clutch AND have 6 cuppa teas in ONE DAY.

Could be an ECU issue, but what did they try or not try and then give up on, during the three weeks?

[neilplumb]

they sent all the data from test drive to technical who sat on this for days to make a decision .
Annoyed as they obviously didn't test before they gave it back  .
I am sure this is a mapping issue , still waiting for response .

[Purplehazeffc]

I still think that this is still a possibility.
The Electronic Boost Control Solenoid. It is what controls the boost level.
The Hyundai standard ones are fully plastic.  It has shown on the Dyno in the US that they can lose boost.

This is an upgraded plug & play version available. MAC BOV Solenoid Upgrade for turbocharged Kia and Hyundai vehicles

Maybe get Hyundai service to install a new factory one & see if any difference.

[neilplumb]

update is : Technical support are coming to dealer to look at car next week !!
Lets see what the outcome is .

They appear to be doing  a lot more than many other dealers/manufacturers would do in the same circumstances! 

In fact, Aussie owners with a warm start issue in the current PD SR have been struggling to get this much support.

Best of luck.
