I returned the throttle body yesterday to the breakers and got a refund and the one I've got off ebay is the exact same part numbers,sorry for my ramblings this car is driving me mad

Hi col,maybe I haven't explained in enough depth exactly what's been done to the car, when the cold start issues first occurred there was no check light illuminated, after trying for a while to start the car the morning after I called the aa, when they came it started and the check light came on,he ...

No col I haven't, all last week it's started fine from cold, maybe I have a separate problem now? If it fails to start from cold again will try the jump leads on it, I've bought a secondhand throttle body off ebay,as the breakers one I got the plug was slightly different, mine is a black plastic bos...

initially it was just a cold start issue but after I changed the map sensor the car ran terribly and seemed to want to stall if you revved it and let the revs drop back down, my so-called Citroën friend, was supposed to have cleaned the throttle body and did a software update for the cold start cycl...

It's electronic throttle control

Also to check the earth's and clean them do I need to disconnect the battery or just have the ignition off?thinking of doing the bsi reset at the same time

Update, since I had the aa come out last Sunday and clean and reset the throttle body and throttle pedal it has started fine when cold,I also drained my oil and ran flushing oil in for 30 minutes before draining and refilling with fresh oil and filter,all ok until sat on a long run,coming back it st...

It seems to play up anywhere below about 4 degrees and it's bitter cold here at the moment, it's 3 but feels about -3 with the wind chill,above this it seemed to run ok

Well it's something I've not even thought about to be honest but it has run perfectly since, I'm thinking it wasn't opening the butterfly, and his diagnostics showed no values and the engine wouldn't rev, if the flap was stuck shut surely no air it wouldn't start?

Hmmm think my "mate" won't be getting my money again, not sure about the cover will try it,don't think the stepper motor splits from the throttle body, can anyone tell me,my throttle body is a plastic housing with a metal flap and all the new ones have an aluminium body?

Also I'm still getting the random beeps and it seems to be getting more frequent, I live up a dirt track and it's quite bumpy, dodgy earth maybe? Which earth's do I need to check and do I need to disconnect the battery prior to cleaning? Or is it just my battery isn't up to the job?

Right thought I'd give you a quick update to my cold starting problems, I got my car back Friday from the guy who works at a Citroën dealers and he'd supposedly cleaned the throttle body and done a software update that richens the cold start cycle up and advised me to do a proper oil flush using a f...

My mate has taken it now but will tell him,out of interest why does it beep when I unlock it and open the door? Thanks again

Sorry col,it was dark when I looked the other day, upon a proper inspection and removing the cover more it does look pretty new,whether it's up to the job is questionable

My mate has taken it tonight, he works at Citroën and he's very clued up on the electrical side and diagnostics, just don't want to keep throwing money at it and not curing it,see what he can find,thanks for your advice and will pass it on
