Too complex to maintain
Any Renault with a al4or dpo transmission, this unit suffers from debris from the friction clutches with the steel spacers pumping the debris around the unit causing damage to valve body/solinoids/seals/bearings/bushings /torque converter, the fluid for these units HAS TO BE FULLY SYNTHETIC, not dextron 2 or 3 or semi synthetic, these units run hot and have poor cooling and I'm in the UK, the unit has a condition sensor that measures heat/viscosity and will flag the computer to limp mode,lock out if the fluid gets thin, another fault probably caused by debris is the converter lock up not locking up between shifting this causes the engine rev up because the converter can't lock the drive to to the diff/wheels and it thuds in it can flag limp/lockout,
Basically this unit has been designed to make millions for Renault dealerships, even if you replace the emv valves/solinoids you need to upgrade the software, if you think you can reset the gearbox computer with an after market diagnostic unit think again because the Renault clip software is only used by transmission shops and Renault,
There is a counter in the computer that has to reset after fluid is added, our Renault modus does not have a drain plug but did manage to get 2 ltrs out via the condition sensor at the bottom of the box, I did not have the engine running at the time but will try that one later .
Right diggers that's my take on the Renault automatic al4 /dpo as fitted a lot of Renaults
Hope it helps !
Great van, just lacking some more seats
I've owned a Kangoo since new, picking it up on April Fools Day, 2006. Since then, the van's reliability has been nothing short of remarkable: apart from the coil packs. Every single one factory installed has failed, and within 3 years. The replacements haven't missed a beat. It's also a pity there has never been additional seating offered, as can be found in Europe.
As a car, it drives better than any other small van, apart from VW Caddys. Blows my old Combo out of the water. I can fit anything I want into it, the dog has a nice space to sit in, and the ride is comfortable enough to drive to Queensland and back with ease. (done this 4 times) Even the wife enjoys sitting in it!
Cheap to run, reliable as all get out.
Coil packs failed, servicing can be expensive...
unreliable, costly, total regret buying this car
2006 Kangoo Renault - bought brand new. I have replaced the alternator twice, fuel pump, starter motor and now the transmission. Also the paint is fading badly particulary on the roof and bonnet. It is very unreliable. Parts are difficult to source in Australia. No after sales service!!!!!!!! A nightmare to own
originally purchased as it was converted for a wheelchair car
Major mechanical problems.
