engine revving sound while changing from fisrt to reverse and vice-versa

Hi All

I had purchased a Hundai I10 recently and am also new to driving.While changing gears from neutral to 1st ,2nd,3rd,4th and 5th it works fine without any engine revving.

When I have to take the car out , I experience engine revving sound while changing from fisrt to reverse and vice-versa.I am pressing the clutch fully while changing 1st to reverse without any break applied.I also had to press the break fully in addition to the clutch being fully pressed so that car does not move.In both cases I am hearing the revving sound(I have not pressed the accelerator at all).Additionally I am getting a burnt smell and the bonnet of the car gets very heated.

Can someone please let me know if I am doing anything wrong while changing from fisrt to reverse and vice-versa.If so how should it be done precisely.If not could there be some problem with the clutch plate bearings ?

Thanks for the help.

Do you change from 1st to reverse (and vice versa) without stopping first? If so then that should not be done. Always stop completely (using brakes AND with the clutch fully depressed!!) before going from forward to reverse and vice-versa.

For the burning smell - I guess you are slipping the clutch (even a slight pressure on the clutch pedal will cause it to slip - ensure you fully press it down). Keep the clutch either fully pressed or fully released except while moving the car from a complete stop. Slip the clutch too often and you will end up spoiling it.

The reverse gear will not engage if the car is in motion (forward).  For new drivers, engaging the reverse gear (& visa-versa) is not very easy & comfortable.  I feel the noise will stop once the gears are engaged properly.

No Boss! Dilip clearly tells us the revving is IRRESPECTIVE of whether he uses the brake or not. He is NOT moving when he changes gear from 1st to reverse. Revise your answers. (BTW I Have no clue whatsoever )

I did notice that but mentioned the following in view of Rohit's query to Dilip (do you change... without stopping first?)

Otherwise, I reiterate that the noise may be due to improper positioning/engaging of the gears...

My take on this is that the 'engine revving sound' is something else all together

-the engine sound will change slightly when the clutch is depressed and this change will be more noticeable when using the reverse as that will be the most quite operating condition for the user! So in essense there IS a sound but its not that of the 'engine revving'.

The other option is that after the reverse is engaged and the clutch let out(without the accelerator) the RPM will be increased by the ECU to prevent a stall.

@Dilip: You say that you get the problem while taking the car out (from your parking space) and going from first to reverse. It is normal for the engine to 'race' a little when you take the car for the first time after parking for a while. The car's ECU does this in order for the engine to heat up, and then you will have normal operation. After you engage first gear and move forward, bring the car to a complete stop, shift to neutral, and if necessary wait for a second or two for the revs to drop before shifting to reverse (and make sure your clutch is fully depressed). As for the "burning smell" it could be the smell of petrol as initially the ECU will deliver a fuel-rich mixture till the engine heats up. I also hope you are using the clutch correctly and your handbrake is not engaged when you drive the car.

Hi Everybody

Thanks for the replies.Like I mentioned earlier I had brought the car to a complete stop by pressing full clutch and brake and the n changing (1st to reverse), but I used to experience the problem frequently .

Due to this I took the car to the Hyundai Service  Centre , the mechanic tried changing the gears but it was not shifting smoothly.Funnily the gears(all the gear 1-5 and reverse) shifted properly when engine was off , but used to lock when changing any gear position when engine was off.He initially told that there may be some gear synchronisation problem due to a pin problem , but after more careful examination he told that the gear box has to be replaced and would take a week's time.Luckily for me this was covered within the warranty period(I10 car only 3 months old).He went to explain that because of the faulty gear box the gears are not engaged properly.

Can someone please let me , if this is a common problem in I10's alone (since gera placement is forward position in comparison to the conventional position of other cars).Also what does one need to ensure that gears are engaged smoothly , if there is a slight mismatch how can one spot it at the earliest ?

Thats a suprising developement!

Seems to me that i10 is having a good deal of reliability problems-there was another member who had his whole engine replaced and another with gearbox issues.

Dilipdo you have extended warranty?

No I do not have the extended warranty.Currently I have the default 2 years warranty that comes as default with purchase of the car.

Some of my friends told me that since it is a new car we need not be worried about parts for atleast 5 yrs.Hence I did not want to shell out money for extended warranty immediately.

Due to this gear box problem I am having second thoughts now , is it absolutely essential that I take an extended warranty , or is this an one-off incident that the I10 part was faulty.If so how many years extended warranty would be appropriate ?
