Hi I have owned my fiat sedici 1.9 diesel for a 12 month but last week she became very low on power when pulling off until the revs build up. I clean the EGR which was all sooted up and it have made an improvement but it’s still abit low on power to what it was there is also grey smoke when coming from exhaust when I rev it up which it did not smoke before...any advice I would be grateful...thanks Fred
 
Check boost pressure. Sounds like it has trouble maintaining enough boost when the ECU cranks up the injection (grey smoke = unburnt diesel fuel)...

Hi niggles
thanks for your help but this might sound like a stupid question to you but can you tell me where the boost pressure is located please
Thanks Fred
 
I took the plug out of the air flow meter, got full power and performs like it should I’m thinking the fault was in air flow meter
