Hi all
ive had this car since new only covered 8300 miles
had problems late last year car constantly coughing and had erratic running
fault found by dealer to be exhasut gas release valve and ECU
had these replaced
now i have similiar problem back again after doing just 1800 miles
after approx 5 minutes of use when the car is up to 40mph the rev counter is constantly boucning up and down - engine appears to be 'hunting'
effect feels like im tapping the accel pedal - its like driving a see saw!!
been back to the dealer twice now they tell me no fault found!!! im not happy
seems to be poor on pull away and hold back then power kicks in - yesterday when it did this had clouds of smoke!
anyone any advice on what to do next?

Seems very low mileage for an 07 car. Do you do many miles with it? It might need a good run and a bit of a blast maybe? You could try some fuel system cleaner.
Thats the simple things anyway, other than that it could be a number of things. The MAF sensor can cause poor running and a sluggish perfroamnce when pulling away.
Its odd that it seems to be causing quite a problem and yet its not recording a fault code.

Hi
thanks for the reply and comments
ive had the car since new only do approx 8000 miles a year
no faults shown on dashboard - the dealer told me this as well.
i dont think they can have road tested it though as both times ive been back with it the fault is there within 5 minutes of leaving the dealers
havent done much motorway work mostly town and bypass even at 5-/60 there is the occasional speed change on its own
my previous 2 c5's had no issues both 2.0 but the 110 versions. this is my first auto though
its just getting unacceptable to drive so i'll be back to the dealers early next week but i'm not hopeful
i have tried the highe performance diesel but its made no difference
thankfully its under warranty

The only thing i can suggest is, cars with FAP filters need a bit or motorway use to get the car up to high temperature for the filter to do its work.
Your current C5 will have this filter, but your previous 110s wont.
It might be a good idea to give it an hour or so run at the limit down the motorway and see how it goes from there.
Id possibly try that first, but luckily you still have warranty, if your dealer isnt helping, you could always try another?

Sounds like regenerate the particle filter.
I think this involves the computer making the car run at high revs for an extended period of time to super heat the exhaust.
