Clutch/parking sensor problem/error in Renault Grand Scenic

- check parking brake

Now I have Renault Grand Scenic 2005 1.6 16V and had to solve problem with Parking B

rake problem.

On my dashboard appeared after a while a message - Check Parking Brake.

But important thing is, that, the notification disappeared after I push the clutch. Even just a bit, so It is not the Parking Brake (btw. I have an automatic one).
So I was pretty sure that it is not the brake but some sensor.


There are 3 sensors connected to the clutch pedal  and I described below how to get into them and basically fix them.
To do so, you have to dismantle few covers and plastics.
Below step by step in pictures how to do it.

 There are three screws and two clips holding the cover

 Lift it very easy up and then pull toward windscreen

 Three spots where I lifted the cover

 The orange socket is for additional switches

 Blue plug will go off it self after you pull the black buckle anticlockwise

 The cover is removed, now you have full acces to the sensors.

 As you can see you have three sensors (follow the wires); I am not sure which one exactly is responsible for Error so I took "care" all of them

 Two of them are exactly the same (the way they work)

 To remove them twist the body by 90 degrees anticlockwise

 The third sensor is a bit picky. Has a kind of twist lock (take a look on pictures below)

 Now let take a look inside

 Two microbrushes slide on track

 Clean brushes and track - you can use a special liquid called Kontakt (last picture). But just not even a drop of it put on the track, the best way is to use tiny small needle

 Because the body of sensor (grey/blue part) is very flexible, I opened it by lifting it up with flat-head screwdriver (very tiny), then moved side to side

 That is what you will find inside the sensor

 Clean the connectors by soft wire brush, then put a drop of Kontakt

 I was wondering how does it work. Well when you push the clutch pedal the pin goes inside and mechanism disconnect the circuit. But here I found the problem. The spring was not strong enough to move pin back on it initial position. so...

 ... I make it a bit bigger, basically I stretched spring and put it back inside sensor's body.

That fixed my problem. After I assembled all part together again error dissapeared.

Good luck!

Very interesting in this car was engine 1.4 Twinport.

"This is precisely what Opel's engineers have achieved with their variable intake control system: at partial load one of the two intake ports to each cylinder of the four-valve engine is partly blanked off by closing a throttle just before the mixture reaches the intake valve.

As a result, the mixture enters the cylinder at an angle. This creates a swirl effect around the cylinder axis and ensures that combustion takes place reliably and completely.














If the driver calls for full power from the engine, however, the second intake port is re-opened fully to make sure that the maximum mixture charge enters the cylinder..." (http://www.theautochannel.com)


















Speedometer in this car was not showing the actual speed. Mistake maken was about 8-10%.

I expected that someone put the wrong tyres size (an inch smaller diameter) but size was ok.
Maximum speed of the car was 180km/h (112mph) but on GPS was shown 165km/h (103mph).
Average fuel consumption for all distance 7,8l/100kms (30.16MPG).
I found few things that suprised me very well and few that did not make my happy as a driver.



"+"

• boot, huge as for the size of the car, enough room to put few large bags 

 

• short car, easy to parking
• small turning radius
• nice acceleration (especially over 2800rpm)
• average low fuel consumption (small engine but Twinport technology save some fuel as well)
• very efficient AC, after switching off no bad smell coming from system
• a lot of room on side pockets at the doors
• 6 speakers
• three adjustable headrests on back seats
   

"-"

• very bad seats, uncomfortable with only angle adjustment (every 1,5-2hrs of driving need to stop for streching)

 

• noise coming from brakes
• low quality interior materials 

• electric steering windows on the front only

• no steering wheel adjustment
• no fog front lights
• low torque when rpm below 2000 (need to shift gears/speeds very often)
• AC - after switching off windscreen immediately evaporated (even it was 30C outside)

• no light under visors

 The most amazing and at the same time weird was  interior light.
Usually actually every car has interior light switch just beside ligh or it is inside the light etc.
Opel has different idea.

 I was suprised when I found in manual how to switch/manage interior light.
If you want to turn on the light,when all doors are closed you have to pull out main light switch.
Usually this function is for rear fog lights, but this time is for interior light.
I think this is not good idea, as only driver has access to switch and only him can turn on/off interior light.


 




Summary:
In my opinion this car is interesting option for all who will use this car for going to work, shopping and from time to time for outside of the city trip.
Small engine, small size and large boot makes this car a good example for average class.

Personally I would not buy this car, nor rent it again.


Thanks
