Renault Kangoo X76.I

Hello far away person, yes its fly by wire you will have to get it diagnosed at either the dealers or a transmission shop because of the Renault clip software involved, you can use an ordinary diagnostic unit for engine trouble codes but anything to do with the transmission it has to have the clip software it's there way of generating more millions.

Renaults are loaded with computer based faults transmissions suffer from complex software plus the gear box suffers bad cooling and has 3 sensors one of which is a condition sensor it reads the viscosity/heat of the fluid and will trip limp mode if the fluid gets to hot or to thin.
I drive a 1.6 renault modus it's the same basic set up you have this trans unit is used in Peugeot/citrons/renault over a wide rang of models.
It has a fluid condition counter in the computer so even if you only top it up you have to set the software, if you have a fluid change the counter has to be zeroed or it will keep tripping.

My advice is if you are going to keep the vehicle change the fluid on or before 30,000 miles get the counter reset, fit an aftermarket cooler wit an inline filter and put a couple of magnets on the metal pan. Only use fully synthetic fluid in these units, renault will say never change the fluid, yet every other auto trans mfg says change the fluid at 30,000 miles, the reason for this is that debris from the clutch packs with the steel spacers keeps getting pumped around the system causing damage to the solinoids valves (evm) valve body/seals/bearings/bushings/torque converter, etc. plus metallic particles can short out electrics in the unit.
If its keeps going into limp mode get it fixed because driving it in third gear (limp mode) will damage the gearbox.
They have other things that can trip limp mode such as a defective brake switch, bad earth on body and back lights/corrosion in the fuse/relay box /bad electrical connectors .
Check out peugeot/renault recalls from the UK warranty website then go onto YouTube and checkout AL4 /DPO problems and any renault/Peugeot web forums.
Well I hope this helps you mate if you get anymore probs let me know.
peter in the UK!

Peter, thanks a million. That sure is a lot to be going on with. Beauty of the internet - a man in UK can help a bloke in Australia. Thanks again. Mike

That's OK mate, you need to get as much info on these set ups as possible. I bought a tablet its an A33 it has a function where you can copy any video without the need for any software its called screenrecord and I use it to record YouTube videos on any and everything to do with citrone/renault/Peugeot as they use common parts systems. I also record how systems work and how to test them because there is always some good old boys out there who find away to do it, plus there are instructional vids to be had. I just keep recording them and have built up a database of these by putting a 32gig card in and saving the vids to the card and onto a memory stick, there are some PDF files too. I found a citrons one on the transmission with exploded views and a lot of text on how the system works and why.
Hope it helps you, check it all out.
Regards a pom!
