Default Re: 1st-gen Hyundai i20 (2008 - 2014) : Review

Hi all,

Has anyone driven i20 for more than 75-80k kms without changing gear oil and brake fluid ? Just wanted to check if gear oil is that critical when there are no symptoms of malfunction.

Thanks,
Prateek

I got my i20 CRDi Asta in 2013 while I was working in Chennai (This is an important point to be noted). The engine was super refined, fast and sort of powerful (though not as much as the 90hp figures suggest, probably due to the weight of the vehicle). The vehicle did move quite fast effortlessly on highways touching good speeds. But I still found the acceleration lacking (again for a 90hp). I could out accelerate Maruti DDiS diesels (same class at that time) but not by a satisfactory margin for me.

So I decided to go in for a tuning box. I chose the RaceDynamics Dual Channel box. It was a plug and play and performance did increase in the P2 mode along with a slight increase in noise. But it was nothing like a tyre screeching monster. Also each time I switched the mode between P1, P2, S and E using the remote with my foot flat on the accelerator, the engine cut out and I would have to coast to the shoulder and restart it. After driving this for about 10k kms I decided to do away with the box as the gains were really not that substantial for me(again IMO) along with the stalling problem.

Then I got transferred to Bangalore and moved there with my CRDi. Surprise, surprise.. when I reached Bangalore, the engine seemed even more refined than its usual self. It was so silent almost petrol like. I had a wide grin on my face. Maybe Bangalore climate was good for the engine. Then came on the shocker..After I drove for a day or two, I felt the engine to be low on power than usual. I was befuddled.. How could such a sudden change happen? Did I fill in wrong fuel? Did the air filter get clogged? Did the turbo blow? Whatever it is how can such a sudden drop in power happen while everything else seems fine? Drove it as it is for about 2 or 3 months due to lack of time and other priorities and the car was still running OK. I eventually got used to the present power delivery of the engine. Then decided to travel back to Chennai to settle some pending stuff.

Out of Bangalore, drove down the slopes, reached Krishnagiri, the car was a different animal altogether. It was back to its old self (now forgotten), peppy, powerful and a bit more noisier than in Bangalore?? The idle rpm was near about 1000 rpm in Bangalore, but ‘downstairs’ it was about 850 rpm? What about the drastic increase in power?

I was out of Bangalore only for a day, so came back the very next day. Reaching Bangalore, I felt the lack of power again. I as perturbed by this because it seemed the car did not deliver its specs at higher altitudes. I was so happy with the quality, features, refinement, everything. But this drastic drop in power at Bangalore or whereabouts really threw me off.

So I decided to go in for a remap at Bangalore! After a few hours of coding and flashing and trials, I settled on a map that seemed acceptable to me. The power loss seemed to be taken care of with a bit more of extra pep and I was happy(This is again important because there was not too much of power gain but power loss was corrected).

Now comes the second surprise..I had to travel to my hometown in Kerala after the remap. Drove down the slopes, reached Krishnagiri, the car became a monster altogether. Acceleration was astounding. The car was accelerating like there was no tomorrow. It was leaving vehicles in the same class and maybe 2 classes above for dead. Keep working through the gears, I was reaching insane speeds in the blink of an eye especially with the slick shifting 6 speed gearbox.

Coming back to Bangalore, the car became more docile. The power delivery became more controllable. This was when I realized that altitude had some major major role to play in the performance of Hyundai CRDi engines. I was pretty sure it was not a problem localized to my car because I know other friends who own Hyundai diesels and face this power drop (with so called increase in refinement) at higher altitudes.

(Off topic here, I also own a Ciaz Diesel which is 90hp fully stock and its performance and refinement whether at Bangalore or elsewhere remains about the same).

Hyundai has not done something that that should take into account lesser air density at higher altitudes. This has been done by Maruti!

Presently I have a free flow exhaust with a matching remap that can trounce almost any vehicle on the highways on plains but conditions apply. Once I cross Krishnagiri or likewise towards Bangalore towards a higher altitude, I can just about keep up with a stock Maruti DDiS where in lower altitudes I would have passed it with no effort at all! I can only imagine a stock i20 CRDi vs any Maruti DDiS, the DDiS would easily pass the Hyundai. And this is just due to this mis-programming or whatever I don't know.

I would request owners of the U2 CRDi engine to comment on their personal experiences with their vehicles. It could be the Creta 1.4 or Verna 1.4 or i20 or i20 Elite. Lack of performance at higher altitudes is a problem and it needs fixing. Hope at least the future generation vehicles from HMIL have this problem sorted out.

Hello all,

Seem to be having an issue with my i20 crdi lately, whenever the car is between gear changes or while stopping at red lights or while making a U-turn (basically when the car is in neutral at a speed of 20-30km/hr) the Tacho needle goes crazy, Rpm fluctuates in the range of 500-1500 rapidly after which the needle drops to 500 Rpm and the engine dies. Any pointers as to what the problem could be ?

I just got my car serviced, Engine oil was replaced and the filter was serviced according to hyundai's service schedule. Also Filled fresh fuel but the problem is still present.

I couldn't go to the service centre again but I talked to a mechanic who said suggested using an injector cleaning additive.

Any help on the issue is appreciated.

I was having similar issues with my 2010 Sportz Petrol and eventually after a lot of struggle, I found that the ECM had some issues of wiring. Had some local ECM repair guy fix this. The connection of the wires were damp and it was giving the exact same issue. On neutral, the RPM used to fluctuate and even reach as high as 3000-4000! But if I am in gear, the car used to run fine. Drove the car is such state from Mumbai to Surat (as I have a known Hyundai mechanic there) who managed to fix this issue from an independent ECM repair chap

That's an interesting observation.
It feels i20 doesn't like Bangalore

Did you get chance to try 0-100 and compare the figures ?

Okay so, Went to the service centre today to collect my car but the car had the same issue still.

Ended up going for 4 rounds and 20kms worth of Road testing to finally find out that a Neutral Switch was being shown on the GDS (OBD SCANNER) as the error.

The neutral switch was replaced by them, costs 1820 Rs. And was a 20 minute job after 2 hours of roadtesting.

Tip: If you experience any issue in your car and the mechanic or the advisor tries to pass it off at normal as they did with me, ask them to take a similiar engined car for a Roadtest and observe it for similiar behaviour.

I did the same thing today and that led to the final diagnosis within 5 minutes after 2 hours of them trying to fix it by themselves.
