I have no such problems with my 7 month old IX20 Crdi bluedrive at 5000 miles. I am very intrigued to hear what will happen with your car as you have covered a lot of miles in a short period and something that we owners might encounter later on in ownership. I'am planning to keep mine for a longtime due to the economic sittuation. One thing that may be the problem but i'm sure they have checked it is the DPF filter which if blocked can cause loss of power. Please keep me informed of your problems i am very very interested to hear how you get on. Have you had any other problems with the car??

 

I will certainly keep you up to date on what transpires with the car and the fix applied, at the moment a technical case is logged with Hyundai to investigate further.

 

Assuming it's got a turbo that's the first place I'd look.

 

There is an issue it seems as I have a similar problem with my i30 Hyundai will say theres nothing wrong unless it shows on diagnostics but there is a problem I have done 18,780 miles in 5 months and the cars in the garage for 9th time after having a new EGR valve. If your still having problems please get in touch im trying to get anyone with hesistation issues together so we can bring a case against Hyundai as they dont seem to want to know I can be contacted on castlefordhouse@btconnect.com Cheers Chris

 

Smith1979: TSB HFE12-14-E300-FD is an ECM upgrade to improve hesitation on the 1.6 U2. This ONLY applies to the old shape i30

 

Just to update where we are with the problem so far, have been told by Hyundai UK that a fix is being worked on and once tested will be made available, in the mean time they have suggested resetting the fuel injectors and using premium octane desiel. The injectors have been reset several times already with no joy.
Not holding my breath for the fix any time soon having searched around and found the following link to the Kia forum with the same problem in the sister car running for around 2 years with no fix available, (www.kiaownersclub.co.uk/forum/problem-with-Kia-venga-14-ecodynamics)

 

IX20 flat spot - lack of power

I have driven my ix20 diesel active for just over a year now (12000mls) and had several updates carried out by dealer to try and eliminate this 'hesitation / flat spot' and improve the mpg
This flat spot has been in the car since new and occurs usually below 1700 / 1900 rpm but when the engine hits 2200rpm it goes very well indeed. Some day the car runs well but others it is noticeable but annoying
A new update has helped slightly but still this appears to be a 'norm' in this model of car/engine
I would feel the turbo is not coming in as quick as it should do - and/or a slighly lower gear ratio etc
I also feel that a 1.6 diesel engine would help? just learned there is a new 1.6 diesel version out and this shouls also help the mpg (power to weight ratio) and overall performance
So I have got used to this intermittent and annoying power loss and learning to live with it. I find no problem with my dealer who has no problem updating the software If Hyundai does come up with a 'cure' I shall be asking for further upgrading etc
Again I think it may be down to the turbo not coming in quick enough so maybe Hyundai are focusing on this area within the engine management?
Overall pleased with the car - Engine stop start functing very well, I don't expect the to attain the Goverment mpg figures, comfy to drive.
The only problem was a rattle in rear of car and was cured by a simple adjustment to the rear door/hatch OH and the 'string holding the rear shelf broke
One is ordered ordered today and under warranty otherwise it would cost me ---- wait for it £15 what a rip off so it is interesting to know prices of other components! Was told parcel shelf is around £200

 

Mine has had its first service yesterday. Hyundai Vantage Manchester were very curteous & professional. Explained everything & car was spotless when I picked it up. Well done to them. Everything is working fine on my car including Stop start which works perfectly, I do understand about the flat spot but I think it's something to do with this size of Eco engine. My previous fiesta 1.4 tdci was worse & stalled at times, in fact it was dangerous. They are not designed for speed but the turbo does kick in at higher revs.

I'm getting around 57mpg around town, so far I'm extremely happy with the car. Only time will tell.

 

Have had the same 'flat-spot' problem for a few weeks with my 1.4 diesel (9k on the clock), so mentioned it when I had the first annual service last week. The dealer had not heard of it before, yet on close inspection of the invoice, it says "Install fuel additive treatment".

Sure enough, after a 'spirited' 300-mile trip at the weekend, taking in motorways and some nice steep hills, it seems to be pulling a lot better at lower revs.

I wonder if part of the problem may be that I use supermarket city diesel.

All I have to wait for now is the new o/s/r caliper to be fixed...

I can assure you that supermarkets don't refine their own petrol or diesel, just about every petrol station in the UK is supplied by BP or Esso.

 

Having experienced this problem for quite sometime now and had numerous visits to the local Hyundai Dealer to reset the fuel injector and other relevant systems Hyundai UK believed would solve the problem, they also advised using branded fuel which I have always done, they have now informed me they are aware of the problem and a software update is being developed and tested within Europe, this will hopefully be available in a couple of months time.
However due to my constant complaining and the backing of the dealer they have now given me an hire car until they have the relevant fix available in the UK, not holding my breath this will be solved in two months given the problems they are having replacing brake calipers.

 

Try a test drive in the 1.6 diesel - Completly different car
I feel that Hyundai are possibly dropping the 1.4 and upgrading to help eliminate this slight lack of power and hesitation

 

I have the same problem on my ix20 automatic, they are replacing a part on Friday, said it's to do with fuel starvation and the injectors, but the part is called "brake....something"...weird.

 

Hi KYx, did the part they fixed solve the problem with the engine flat spot, my IX20 as been sat at the dealers for over a month now waiting for a software update, would be very interested to know what the part was so I can once again talk to Hyundai UK customer service and voice my feeling to how poor their after sales service is.

 

Yup...totally fixed and lovely and lively with no flat spot. Not sure I can ask about what the part was, as their service department is being rather grumpy with me at the moment, after pushing them about the callipers. But if you want to speak with them, it's Southend Hyundai and my car was in on Friday, they'll know who it is I'm sure

 

Andy Kyx's car is a 1.6 petrol automatic not a diesel

 

This seems to be a common problem across the entire Hyundai 1.4 & 1.6 Diesel engine range. I drive a 1.6 Diesel fitted to a i30. It has the same symptoms. After giving up on Hyundai to find the fault I have been going through related threads and together with my own experiences have developed a theory.

1/ The fault only occurs on engines fitted with the electronic EGR valve, earlier vacuum operated EGR engines don't do it.
2/ It seems the fault is more obvious on cars with automatic transmissions, but does occur on manuals.
3/ Fault seems to develop after about 10,000 klm / 6,000 miles, and gets slowly worse.
4/ Turning on the Air conditioner while the engine is hesitating/ stumbling cures the problem instantly.
5/ Leaving the Air cond turned on all the time reduces the fault to almost zero.
6/ The fault is worse the gentler you drive the car.

Now my theory, first let me add I have installed a scan gauge unit which reads engine data direct from the ECM and engine sensors, this plugs into the OBD II socket. As you gently accelerate the engine boost pressure rises rapidly, even on very gentle acceleration there will be 3 - 5 PSI boost by 1500 RPM, what I have noticed is that at the instant the hesitation starts the boost pressure drops instantly to nearly 0 PSI. I suspect what is happening is the EGR valve is opening and the inlet boost pressure is flowing backwards through the EGR into the exhaust manifold. For a CRDi engine this causes multiple control issues, the fuel admission rate is governed by boost pressure, that is why you see very little black smoke from these engines they only ever inject the amount of fuel that the boost pressure can use. Secondly, the surge of fresh air (oxygen) past the Lambda probe in the exhaust could cause the ECM to think the engine has misfired and make it adapt a different control scheme, perhaps raising fuel pressure or advancing the injection timing (ignition rattle).

So when you take your car back to the dealer, ask them to plug in their diagnostic tool and to monitor the boost pressure as you very gently accelerate in a manual third gear seems worse. Then we can all wait as every dealer says 'never heard of that problem before'.

My working life has been with power generation equipment, in particular electronic governing and load sharing of generators, I have worked on General Motors DDEC, MDEC, and their latest generation CRDi 2000 and 4000 series industrial engines, as well as the old mechanical engines with Woodward, Heinzmann and Barber Colman electronic governing.

 

magician is back?



Hello there,
that's the best explanation about such problem. but not about the solution.
Personally I'm not facing the problem but the car is too young (800m). As explained the problem could also come from the EGR getting dirty and not closing completely any more.
The solution I applied on my previous car (opel 1.3CDTI) is a final solution: get the EGR cleaned by the garage (in fact they finally replaced it) and then to to a "chip tuning garage" to disconnect the EGR. After that the problem never happened again, MPG got 10mpg more and the quality of driving was unrelated to before. Not to mention I also asked to enhance the power (20 HP more). This is really good money for the result (380£).
Will try that solution next year when the IX20 will have enough initial miles.
Enjoy

 

Kia Venga has now solved the problem (software update)

 

Hyundai Getz 1.5 CRDI 2007 Surging

Hi ,

Very interesting read. Today my diesel Getz started surging to the point I want to drive it down a mine shaft.

I dont know a lot about diesel engines but was wondering could it also be a dirty or contaminated diesel filter ?

 

"1/ The fault only occurs on engines fitted with the electronic EGR valve, earlier vacuum operated EGR engines don't do it.

6/ The fault is worse the gentler you drive the car."

Funnily enough, I have exactly the same problem on my i30 1.6 PETROL auto, although I haven't tried the 'aircon fix' yet. Drive at a 30mph limit, gently accelerate into a 40mph limit, and it'll hesitate/judder sometimes. Hot or cold doesn't seem to make any difference, and it's got worse since about 5k miles (now done 6k).

Just been in for 1st service (where this and other minor faults were deemed my imagination!) so no help there. But according to them, the petrol isn't fitted with an EGR valve (some petrols are) so can't be that.

Odd or what?

Cheers - Peter.

 

Hi Peter, with the petrol burners one of the most common cause of juddering on gentle acceleration is fuel. Some engines seem to struggle on standard grade fuels at certain times of the year. Try a fill up on a Premium grade fuel to see if it has any positive effect. Cheers. Ray

 

Thanks Ray, sounds reasonable. Hadn't thought of fuel quality, and such radical thinking is obviously far beyond the main dealer mechanics who rely on plugging a laptop in.

While the modern petrol engine should operate perfectly on much less than 95 octane, they're all different and it's certainly worth a try on 98 octane to see what happens! And I do less than 6k miles a year now, so it's not even going to hurt my wallet very much!

And thinking about the quality of the normal 95 octane, if I was to get a duff tankful (does happen, doesn't it?) it would certainly be there for a while before it all got used up. So I suppose that's also a possibility.

Thanks again / cheers - Peter.

 

I think in England you have summer/winter fuel blends as well don't you? So it certainly would be possible you could get a duff tank of 'old stock'. Here in Australia we just get the same swill all year round. I've found with the wifes Accent it doesn't like Ethanol blended fuels at all even though it is supposed to be higher Octane.

 

new firmware

:00000732:Hello
good news? for IX20 90HP diesel owners.
I went yesterday to my Hyundai service center to claim again for hesitations during the accelaration. After a new search in data base they find out that a update (dated mid April 2014) #376? is available for cars build between 2010 and mid septembre 2013. This upgrade is called "acceleration" so it could really be related to the problem we are facing. Bad part, they were not able to find out the patch for may car. Could be the info was there but the file is not yet available (so don't rush to your service Hyundai).
Will keep you posted as soon as I got it implemented in my car.
Have a great day.

 

Thank you Broty, keep us posted. I have the same car with similar issues, I was going to take it back in summer months when it is at it's worst along with rattle from the engine.

 

acceleration solved

Hello,
IX20 1,4 90HP
I got to the dealer again today. He was now able to install the latest firmware. and.... IT IS WORKING!
A lot more torque at low rev, a lot more powerful, a lot more nice to drive with.
So it seems something is fixed really.
This is code #376 in their list and it is a firmware finishing by version 5. Applicable to model build 2010 till September 2013.
Please insit to your dealers as it is very new version.
But some strange noise at some level of acceleration like a ratle noise. Could be the EGR opening and closing fast. Will try to analyse more deaper tomorrow.
At least something changed for a better handling of the motor.
Enjoy this real difference.
Good luck with your dealers.

Hi do you know if this upgrade is also for the 1.6 diesel model??? as I seem to b suffering with the same problem & the car is due in for a new EGR valve under warranty as my car will not accelerate over 2500 revs
Old chap

 

last patch applied (dated April 2014 ) and it is working really.
insist to your dealer to get it.

 

Keep us updated on how the car is running. Thanks Broty
