hi, I a hoping somebody can help me. I have a 2006 focus 1.8 tdci, the red warning light came on and then the car started to lose power, it feels like the turbos not coming but its not smoking or losing oil and it runs fine on low revs and tick over, having looked at I the pipes seem ok on the turbo, the airflow metre is ok so I am at a bit of a loss what's causing it. Any help very much appreciated.

an anybody help please ?

Check your egr is not coked up or it could possible be a blocked fuel filter / air filter car also might of gone into limp mode do you have a code reader to see why the warning light has appeared .

Thanks, I have tried all the above and the code reader doesn't show any errors. Another thread mentions the turbo pressure accuator, does anybody know where that is located on the 1.8 tdci please ?

Do you hear any odd noises, whistles or tones in the engine bay when your revving the car?

Hi, no, no noises, we have put some injector cleaner in and it does seem a little better but not right, it's like it's lost it's oomph.

Hi Jackie,

Have you got a trip computer? have you tried to get any error codes?

Can you describe the red light that comes on?

Hi, yes, it's been on the computer and shown no codes ! The light is a red circle with jagged edges and an exclamation mark in the middle. So far we have checked the turbo pipes, took the erg valve off and cleaned it, put a bottle of injector cleaner in it and it still runs slow, it's as if the turbo isn't coming in, when still you can rev it and the electric throttle body moves when it hits a certain high rev, should this move all the time, quite honestly I'm at a loss, had it at a diesel specialist today and he couldn't help, he checked all the fuses but everything was fine !! HELP........

Is it the same light as you get when you put your handbrake on?

Hi, no, its not the same light, this ones on the rev counter side, apparently its a general warning light.

I had my focus go into limp mode about a year ago and it was my glow plugs that caused it. Last week it did it again but without any warning lights, this time I had it full serviced and it has sorted it. You could try both of them.
