Gearbox issue on Renault Megane DCI 1.5

[Macross_vin]

Dear Seniors,

I will like to ask if any of you are driving this particular model, as I have been experiencing it gearbox problems.

A couple of time while in the jam, the panel will display a red message warning me that the Auto gearbox over heated. Did went and told the service staff at Wearners, which they told me that this car is using dual clutch. In a traffic jam situation, it will be advisable that i put it to neutral to prevent it from overheating, as the clutch system well keep on engaging while stationary during the jam.

 

The other problem that i am experiencing is that at times, after starting the engine and move on, i will experience jerking or the gears not changing by itself and will keep dragging the gear when i accelerate. Suppose to move from 3 to 4th gears, the gear will just stuck at 3rd. Feedback to the service staffs before during routine servicing, they told me sometimes it is the on board computer system error, which I will need to stop the car, cut off the engine and wait for a few seconds before restarting the engine again and the problem will go away. This morning such problem happen again while i was on ECP. As i am not able to stop the car in the middle of expressway, therefore, I stop it after reaching the traffic light near Bugis. But before that I switch the gear system to manual while on the expressway. I was on 4th gear and try to swift the gear up as i moved faster, but the gear just skip 5th and go straight to 6th gear. Same thing when lowering the gear. I will skip 5th gear and move straight to 4th while i was on the 6th.

 

My concern now is that as this car is coming 3 years old. Should I get the gear box change while it is still under warranty?

 

Please advise. thanks. 

 

P.S: I am a normal driver whom don't play with manual gear as I used automatic gear since this is a daily car. When i do reversing, I will wait for a second or 2 before swifting from D drive to R.

Pen down the chronology of events and send your car to Wearnes to rectify or replace the gearbox and/or electronics.

 

If unresolved, write to Renault HQ in France.

Do you drive in traffic a lot?

 

When was the last time you changed the oil in your DCT? These things need regular ATF/oil change when used heavily in start stop traffic.

 

But if you are under warranty, Wearnes telling you to switch off car to clear fault code is quite unacceptable. I would go insist they change your gearbox.

sounds like mine as well

Well, i will always choose to travel by expressway as much as possible, seldom will i catch myself in the traffic. Also, my mileage at this moment is already 70k km plus and I have been regularly send the car for servicing at Wearnes as the servicing mileage is set at every 10K km...... 

 

I will check with the service centre again as I'm rather concern on it as I read up that a change of the gear box will cost a bomb......

so care to share what you have done to solve the problem? U also driving a renault?

[Fuelsaver]

Better hurry to wearnes request to diagnose n replace gb if not essential components before warranty expires.

When you did all your regular servicing at Wearnes, did they ever change your DCT fluids?

 

This is important since the factory schedule might call for say changing it only at 75k but since we don't drive on nice alpine roads here, it might be better to change every 30k but agent want to save $ follow factory schedule......

 

Go bang table, keep a log so that after warranty they cannot tell you oh need to change GB.

 

basically before warranty expiry : Oh you can switch off engine and clear code

after warranty expiry : Oh this one need change GB.

Am not a owner, but what you experience on a DCT(dry) car in traffic is characteristic. 

 

To put in nuetral is uncecessary as the computer does it for you anyway, makes no difference. The main resaon for the overheat is the "creeping" in which there is slip.

 

In jams, you are using the 'creep' function to keep up with traffic gaps. This is synonymous to using a Half-Clutch on a manual GB. Imagine half clutching for long periods and the heat generated from the friction plates will be "smell-able" from the outside.

Hi All, need some advise. My 2013 grand scenic gearbox need replacement after consulting wearnes. Car could not start. It is coming to its 5th year only in Jan 2018. Damage $6k! What alternatives do I have other than spending that kind of money on new replacement? Thanks.
