Engine Sluggish

[Patteri]

Hi

I have a citroen c8 2.2 16 v

Recently the car has turned gutless , literally powerless until the turbo kicks in

Once the turbo kicks in then drives fine

However most of the times , specially with cold engine will straggle to set off in first gear let alone second

I have had it plugged in into a diagnostic machine and the only errors are break pedal switch and fuel tank filler cap sensor

According to the mechanic this two could effect the performance and be the cause of my problem ,

I personally think is a lot of rubbishðŸ˜ðŸ˜ðŸ˜ðŸ˜ðŸ˜

Can anyone confirm or dismiss this theory ??

I have unplugged the air mass sensor to see if it was the cause , but when i did it was even worst and the turbo didnt kick in at all

Any ideas ????

Is your car a diesel and does it have an exhaust particulate filter ?

If yes, the filler cap will have 2 magnets in it (if it is like a C5) that tell the car when it has been filled with diesel and then inject some eolys fuild in the fuel tank. If this is not working then the exhaust filter could be blocking up.

 

I do not know what effect a faulty brake pedal switch could have but it is not likely to be expensive. However, maybe if the car thinks the brakes are being applied then it may affect the engine.

 

Could you post your indicator problem again since for some reason they do not open, or just add it to this topic. I do not know if it is something to do with the squares that appear below the title but perhaps you could try without these.

I have deleted the indicator posts since nobody can open them.
