HI, may i know how much force distribution for front/rear brake on megane rs250. eg; 50/50 or else. thanks and best regards,

nasrol, 4th Apr 2018


Hi, Because of the way the ABS works with all 4 brake calipers of different size [front and rear], it isn’t a true 50/50 split. Ultimately the ABS distributes the force to the caliper/axle that needs it.

Clio not starting

Hi, I have a mk2 Clio campus, and when I turn the ignition nothing happens apart from a click under the glovebox and one of the wiper arms twitches. Any idea what it could be?

Hi Jamie, It'll be necessary to fault find this first hand and trace the power distribution and operation of the ignition system, etc.

My renault megane 225 sport

Hello Carl, It could be related to build up of oil deposits around the throttle butterfly or something related to emissions. I'd recommend the injection system is interrogated and diagnosed properly if the engine w/l is illuminated.

Clio 4 RS 200 - Wheel Spacers

Hi Allen, Is it possible to introduce wheel spacers to the rear of the car in order to widen the track? A personal gripe of mine with the car is the fact the rear wheel arches sit so far over the rear wheels. I was hoping to make it wider and therefore look a bit more aggressive. Cheers, Lewis

Clio 4 RS 200 - Wheel Spacers

Hello Lewis, I'm sure wheel spacers will help change the cosmetic impression of the car - it'll also have a big impact on the dynamic behaviour. Personally i'd avoid it.

Alarm (1)

I have a 2006 Renault megan dynamique hard top convertible. When I start the engine the alarm goes off it has been in garages to disconnect alarm but they don't know how to. Can anybody help it's making my life hell

Pauline Jones, 11th Jun 2018

Alarm (1)

Hello Pauline, As part of the cars insurance rating it is not possible to disconnect the alarm. If it is randomly discharging you can switch the state of the alarm so it only registers when a door, boot or bonnet is opened. This can be achieved via a specific sequence and using the RENAULT card/key. This information is in the owners pack or contact Renault Customer Services and they can send you a copy for your specific car.
