I have a 2006 Doblo which has started to make a loud sucking noise. You can't really hear it when it is ticking over or reving the engine.
But when you are driving (and the faster you go) the sucking noise gets louder. When you take your foot off the gas pedel it stops.
It sound as though it is coming from the rear of the engine, as its louder with the window closed.
I had a new airflow meter fitted no more than 2 months ago
No holes in any pipes that I can see (or feel, as you know, hard to see any thing at the back of the engine).
Power feels low but seems to run ok (no spluttering ect) and no smoke from the exhaust.
any Ideas (EGR valve maybe ?)

Hi, not sure if same as 1.9 jtd, but have had the pipe under the radiator that feeds intercooler rubbing on intercooler and holed it, and when turbo boosts it can be heard blowing out of hole. As this is causing pressure loss on air intake of engine there is also power loss,maybe worth checking. Also check all boost pipes for splits, easier to find with turbo boosting as you should be able to hear/feel air loss. If you've had a maf sensor check pipes are properly located/clipped and haven't come loose/moved.Hope this helps,John.

I have just had a look, but still unable to locate where the hole may be. It cant be very big as it seems to be when you are driving (engine under load).
I think you may still be right, just got to find it.
Cheers
 
hi have a look at flexi joint on exhaust if its got soot around or onit its failing
 
If it's turbo Diesel then i'll put money on a turbo pipe split, check all hoses and exhaust.
