My wife's kangoo which is just out of warranty is showing the following symptoms:
intermittent loss of power - usually when the motor is hot and at about 2000rpm and put under load
a refusal to rev above about 2500rpm by use of the throttle pedal
it will rev faster if thrown into a low gear and sometimes this puts things right
it always sorts itself out if I switch off and restart.
Any ideas out there? Is it a sensor, a valve or the "fly by wire" throttle potentiometer/ Must I take it to a main dealer to have it checked?

Possibly
>>a valve
EGR possibly clogged - specially if reving it clears it.
>>or the "fly by wire" throttle potentiometer
probably not
>>Must I take it to a main dealer to have it checked?
Someone needs to check it

Thanks for your advice. I took it to my local main dealer who could find no stored fault code ?! but suggested that a sticking EGR valve might be to blame. They are fully booked up for this week so I have time to think. Can I clean one myself or is this a job for a specialist?

My daughter had 2 EGRs replaced on her 1.5DCi after similar problems (and at quite a cost).
RAC diagnosed a faulty throttle potentiometer which was replaced - been OK in the month that has followed.
Thread about it is here

Took the car to another dealer ( after another breakdown!) who diagnosed a faulty EGR valve using a stored fault code. Charged nothing to do this and said that it would be as cheap to replace it as to clean it and anyway that cleaning rarely provides a solution. The technician was surprised to see this problem on a 1.5 - more common on the 1.9. Will changing this cure it or can this be hiding a throttle potentiometer fault like PhilW's daughter's car ?

"The technician was surprised to see this problem on a 1.5 - more common on the 1.9."
That was exactly the story my daughter got - EGR fault very rare on 1.5DCi - especially on a car like my daughter's which does a 50 mile commute up and then back down the M11 each day.
Problem was that EGR fault code registered occasionally and then after new one had been in 2 days car broke down again. Then RAC man said he saw a brief flicker of throttle fault when test driving it - it only showed for a fraction of a second when he happened to be looking at screen on his mobile computery thingy.
He said way to test it was to drive it back from Cambridge to London, if power loss occurred , switch off ignition (careful!!! only to first click on switch - don't engage steering lock!!!!) and switch back on immediately. I drove it back and power loss occurred 6 times, each time I did a quick click off and on, potentiometer reset itself each time and I carried on (entertaining when overtaking on M11!!). He said this meant it was potentiometer not EGR.
No probs in month or so since - daughter has done commute each day and we have had no phone calls to say "stuck in outside lane of M11 again, but don't worry!" which was fairly frequent and worrying previously!
Good luck
