got a mondeo tddi and it is like the turbo isnt working,but you can here the turbo when car is reved any idears?

 

is it possible you have a boost leak maybe?

 

is your glo plug light on?

 

Had this before on TDDi's where there was no coil light flashing or illuminated yet the car was flat and gutless. Swapped the injectors and it was fine again.

I'd have thought a boost leak would bring on the coil light and produce a fault code relating to either inlet manifold pressure or airflow upper threshold exceeded.

 

A boost leak won't bring on any warning lights.

 

no warning light on just very flat, but i can hear turbo when car is reved had pipe off 2nite and turbo spins free?

 

egr valve maybe gunked up

or

the air flow meter is a favourite when they go gutless.from memory if you plug this out and their is no change ,then its fooked

 

Wrong yes it can i seem it a few times

 

boost leak can put light on, most likely turbo underboost fault code or boost pressure sensor fault, as above, check all the boost hoses for splits etc.

 

Check boost hoses. Had one last week with split on one left hand side of bay.

 

seen lack of boost not put lights on and put it on, depending on driving conditions.

id start with EGR if no boost leaks personally

take some live data ideally with a good scanner

 

thanks lads

 

On TDDI? Are you sure? On a later TDCI, maybe, but not on a TDDI, or Euro3 TDCi.

 

Yes positive don't believe everything you read on the net!

 

Had this exact problem last week on my 53 plate zetec s tdci, completely gutless and flat

Checked the hoses and the cooler to egr valve hose had a large split in it, fixed that and it's good as new again,

My coil light or engine light did not come on or flash

 

I'm talking from personal experience, not what I've read. Where was the leak that caused the fault code, and what code came up?

Shame, I could have sold you a silicone one for a very good price!
If you fitted an OE one they can go again within a year!

 

How much are the silicon ones I fitted a gen ford one yesterday!

 

Dan - I used tape to fix it :cry


When that fails il buy a new hose, how much are they then?

 

I done one with eaxct same symptoms last week. It was the elbow shaped pipe going on to the right hand side of the inlet. The split was on the inside of the elbow. Very hard to spot.

 

The pipes cost up to £90 from Ford - I sell Silicone ones for £45 - and i'll guarentee it for the life of the car!
