After driving for another 10 km, I was at second gear and the problem occurred again. This time I downshifted to 1st gear and the issue disappeared. The problem never occurred thereafter. I drove around 85 km yesterday and around 45 km this morning and didn't observe the issue. What could have caused the issue?

I observed this phenomena in my recent trip from Blr- kol, after I filled diesel from some place in Andhra. I felt as if the car blew its turbo! Meaning, sudden power loss! Downshifting was of no use. There were no checklight's glowing on the dash. Continued driving till I reached a good IOC pump. Refilled diesel and the car came back to life after driving for some 15-20 kms. Hence I concluded that it was probably the adulterated fuel that caused this to happen.

The above situation did not re-occur!

In your case there was power loss and the issue went off after refilling diesel. In my case, there was zero power when the issue occurred. The throttle was dead and there was a very mild breaking action too. It came back to life only after down shifting. Also the diesel was filled around 4 days back before the issue occurred.

I was planning to take the car to service center but the issue is not reproducible now. I don't think the service guys will be able to do anything until unless the issue is reproducible. Sometimes they can't find out the exact cause even if the issue is reproducible .

Okay, in my case also, at that moment, I felt that the car lost power and died for a fraction of a second.

Anyway, please follow the steps and see if you're facing such an issue!

When idling the car, with the bonnet open (ideally in a very quiet area) press the throttle very very gently but frequently, it should be so gentle that the rpm's don't increase more than 100-300 (tacho indicated)rpms.
For eg, my car idles at 800rpm, so when I tried doing this, I ensured not to cross 1100rpm on the tacho! Anyway, you would be listening out for any sort of "kissssk kissssk" sound when you step on the throttle pedal or leave it. Hear very carefully, you cannot miss this sound.

If you are getting this sound, I'm afraid its one of your injectors (the i20 getting the shittier Delphi system, unlike the Verna with the Bosch) that has an issue, most probably its plunger is defective. You will have to replace it.

You could choose not to replace it, its not that the car will stall and wont be drive able, but if its under warranty, get it changed. The change in sound can also be felt by touching the fuel pipe connecting to the injector.

After you have detected the sound, have the HASS connect the G-Scan and run a diagnostics on it. While they check it, you could also ask them to update the update the software for the ecu as it is available for the i20. After the update, the car feels a lot smoother and powerful.

Before you do any of the above, please ensure that the lever on top of you diesel filter is as hard as a rock!! I get my diesel filter changed at every 5k kms, so many a times the junior mechs don't prime it well. Upon informing the senior guys pump it till the level is rock hard!!

Hope this helps.

Thanks for the useful information. I'll try this experiment tonight after going home.

The car is not under warranty. The odo stands at 99,000 km.

After you have detected the sound, have the HASS connect the G-Scan and run a diagnostics on it. While they check it, you could also ask them to update the update the software for the ecu as it is available for the i20. After the update, the car feels a lot smoother and powerful.

Should I ask them to perform the above experiment while the G-Scan is connected? Is the update available for the old i20s too?

No, please don't tell them anything initially, as your car is not under warranty.

To be very honest with you, if the plunger is defective, you will still not see any errors on the G-Scan. The reason why I'm asking you to get a scan done is, that if there are any other pressure related issues, those will be caught by the scanner.

Once you're done with the scanner, you could then tell them that you're hearing some weird sounds "AFTER THE FILTER CHANGE" and it was non existent before. ( this only to grab their attention)

The update is available for the u2 1.4crdi 6speed 2012 and post that models. Not sure if your's a pre or post 2012.

Also, Dinesh at Advaith Bannerghatta has left and is now in Dubai. So if you go there you'll have to speak to someone else! AFAIK he was the only knowledgeable guy in that WS!

Shrey, thanks for the information.

Mine is a 2011 model. So I assume that the update is not available for my car.

Also, Dinesh at Advaith Bannerghatta has left and is now in Dubai. So if you go there you'll have to speak to someone else! AFAIK he was the only knowledgeable guy in that WS!

Dinesh was the SA for my first three services after which I shifted to Advaith, ORR. Vikram at Advaith, ORR is pretty knowledgeable and will contact him for this. Wonder what Dinesh is doing in Dubai!

Tried this experiment now but not hearing any such sound. I'll mention about the issue to SA during the next service which will be done shortly.

That's good news then!! Injectors are very costly!

What about the diesel filter pump lever? Was it rock hard?

Please do update if you can find the root cause!

Yes, it was hard. I'll mention about the issue during next service. But I highly doubt if they will be able to find the root cause since the issue is not reproducible.

Congratulations on reaching the milestone. Wishing you many more.

Good to see the car being taken care well by Hyundai. I can relate to that excitement of seeing '100000' kms on the odometer. How much time did it take btw?

Where are the pictures if the odometer and the car?

EDIT: Do update the thread title!

1 lakh km update

It was a fuss free journey until now. The car didn't face any major problem. The few minor issues faced were promptly rectified by the Hyundai service center.

Services:

The total service costs:
1. 1st service @ 5000 km - 0
2. 2nd service @ 10K km - Rs.2506/-
3. 3rd service @ 20K km - Rs.5152/-
4. 4th service @ 30K km - Rs.5917/-
5. 5th service @ 40K km - Rs.6076/-
6. 6th service @ 50K km - Rs.6323/-
7. 7th service @ 60K km - Rs.8751/-
8. 8th service @ 70K km - Rs.9987/-
9. 9th service @ 80K km - Rs.8719/-
10.10th service @ 90K km - Rs.8465/-
11. 11th service @ 1L km - Rs. 10347/-

The first three services were carried out at Advaith Hyundai, Bannerghatta road whereas rest of the services were at Advaith Hyundai, ORR.

Issues faced until now:

1. Engine misfired twice at 30K km: A problem was found out in one of the main wiring. The wiring was replaced under warranty and the issue was resolved.

2. Engine knocking sound at 1000 rpm at 70K km: A 20 digit code in the ECU which controls the fuel injection was reset during the diesel filter replacement and this was the root cause for the problem.The issue was resolved.

3. Front passenger seat rattling at some positions: This issue is present right from the day of the delivery of the car. The rattling sound appears only at a particular position and if no one is sitting on it. The issue is not resolved until now. The temporary fix is to change the position of the seat.

4. Hyundai could have provided better under-body protection for this car. I had a nasty incident with a stone which is reported in the other thread.

Upgrades:

No major upgrades are done to the car. All are minor upgrades. Majority of the spending was on the detailing products .

Lights:
The stock headlamps of old-gen i20 are very weak. I replaced them with Osram Nightbreakers. It's working absolutely fine after 1.4 years and 60K km. A set of fog lamps were added last November and they are working fine.

Horns:
The car came with OEM dual horn setup. This was not sufficient for the kind of traffic/people I encounter on roads. I rarely use horns but when I use, it has to be loud enough to grab the attention of truckers, etc. The OEM horns were replaced with Bosch Symphony. It conked off after serving for around 10 months. Later Roots Windtone replaced Bosch which served for a year. Now I have installed Minda trumpets. Its serving well after 4 months of installation. There were no wiring modifications done for installing these horns since the car came with dual horn setup from the factory.

Tires:
The car came with Apollo Accelers which served very well for first 58K kms. They were replaced with Yokohama A-drives. They are still going strong after running for 42K kms. I have taken both Accelers and A-Drives to God forbidden places and both have performed very well. While the Accelers had only one puncture in it's lifetime, A-Drives already had 4-5 punctures.

3D Mats:
Its almost 3 years since 3D mats are installed. The driver side mat started deteriorating just after 4-5 months of usage. I'm still using it only for the sake of grip it provides, else would have throw it away. It's not worth the amount according to me.

Dolphin seat covers:
I got these artificial leather covers as soon as the car was purchased and it has really served well. It hasn't shown any signs of ageing. It's very easy to clean, does not sweat during summers and gives nice looks. This is one of the best accessory I have purchased for the car.

Detailing:
I was just washing the car regularly during the first year of the ownership. I was least bothered about the minute details like swirl marks, hairline scratches, etc. I then started reading very good reviews about 3M car care and hence took a 1 year package from them. Therefore the detailing was taken care by 3M during the second year of ownership. It was then the detailing bug caught me and started doing the experiments by myself. I belong to the OCD group now

Other points:
1. Except the passenger seat rattle explained above, there are no rattles from any part of the car.
2. All buttons are strong and sturdy. No buttons have come apart or showing signs of ageing.
3. The creamy CRDi engine is still butter smooth. It feels like a new engine. It never complains for power at any speeds.
4. FE hasn't changed over the time. Have been getting 16-18 kmpl in city limits and 20-22 kmpl in highways.
5. Running on stock clutch.
6. The AC vents adjuster is very delicate and breaks even if utmost care is taken while using it. Have replaced thrice under warranty.
7. K&N air filter was added at 89K km.

To sum it up, I absolutely enjoy driving this car. It has never let me down anywhere with any niggle/issue. I have taken it to some of the toughest terrains (sedan/hatchback standards) in Dakshina Kannada district and it has never disappointed me anywhere. It has been a very reliable workhorse for me until now.

Thanks Anurag. It took 3.3 years.

I have captured the odometer pics in my camera which my friend has taken. I'll post it once he returns my camera this weekend.

Congrats Vinay. Yours is the first i20 diesel I know of to have crossed a lakh mark. Also happy to hear that the heart of the car is running trouble free. Gives a lot of confidence to people like me who are still at 56k kms

Thanks Sagar. The heart of the car still feels brand new. There is absolutely no change in engine note, pick up and fuel efficiency. It's as smooth as when it was brought out of showroom. I casually asked my SA about the characteristics of CRDi engines after 1 lakh km. He mentioned that most of them stop coming to the authorized service centers once the car is out of warranty. He has come across some i20s that have crossed 1 lakh kms which are performing well without any issues. One particular i20 which he services has crossed 2 lakh kms.
