Air flow issue after replacing or cleaning everything in the air flow

[Andycgull]

So, I have a 2019 berlingo which I’ve have replaced,
Maf sensor
Map sensor
Turbo
Ccv breather, pipe and sensor
Upstream o2 sensor
And cleaned out all the tubes, boost hoses and inter cooler plus other parts along the way!
Egr valve brand new too!

Oh and I’ve done an oil change, fuel filter, oil filter and air filter change too

It drives fine for about 10 mins then as I slow down, voila, there goes the engine light and air flow code!

Any ideas please anyone as underneath my bonnet is now like triggers broom!
Thanks,
Andy

faulty ''new'' sensor? did you use original part's ? what made you change all these parts on a 19 plate?

[Andycgull]

Yeah all Bosch or top brand parts from my local motor parts direct!
The turbo had gone and was leaking out the side which found when I got original maf sensor fault,
Took advice from people saying oh it’s this or that and ended up working my way round with new bits lol! Now I still have p00bc and pe2ed21 which I know what they are but I can’t work out how to solve it or why it’s there hence the seeking of advice from you fine people lol

Local motor factor parts may not be the same as ones from a Citroen dealer so may not be original parts. If you post your VIN it will allow admin to look up the fault codes against your car.

There is a similar topic for the 1.6 hdi engine and it appears for this engine there is a Technical bulletin for these fault codes viewtopic.php?t=64059

[Andycgull]

Thanks for your reply Paulc5 I’ll do that when I get a moment today

Oh and my absolute throttle position is always at 100% whether idling or just ignition on I’ve just noticed

One of our cars is like this using live data on our code reader, could be the Cactus but there is nothing to suggest there is anything wrong. Maybe Citroen diagnostic equipment might show different values.
