Resolved Question:

Hi I have a 2007 ford focus 1.6tdci which has lost power and takes ages to build up speed but otherwise drives perfectly doesn't seem like turbo is working

Hi there ,good afternoon to you

Ok your vehicle is fitted with a variable vane turbo
These turbos were prone for seized (starved if oil ) on the earlier 1.6tdcis
The easiest way to see if the turbo is seized and first check that should be done is to remove air inlet pipe (between air filter and turbo (with engine off ) and check the condition of the fins on the inlet propeller ensure they are ok and rotate smoothly (if the turbo has seized it won't move and normally the securing nut will have come off

Of the turbo looks and feels ok refit the hose and then get someone to start the engine up whilst you look at the turbo
You should see the thin metal rod (used for variable vane adjustment )
This rod should get pulled downward after start up

If this isn't happening and the turbo is ok the vacuum control for the turbo should be investigated which we can continue out diagnostics on this same post

If you need anymore help or advice on this issue please let me know
If you are completley satisfied with my answer /advice

Kind regards ***** ***** and have a nice day

Hi again Brian, while I was waiting I disconnected connection to airflow metre and it seems to have improved performance, regard's John

Hi there john thanks


Ok if you think this has brought the power back it could be oil contamination on the MAF sensor
Ford released a larger breather hose from the rocket cover /air filter to stop oil blue back from the turbo
We usally just clean the MAF with brake cleaner and monitor the issue

Would this problem also cause it to be smokey ?
Expert:  Gallagher99 replied 2 years ago.
Hi john

It can cause smokiness if the MAF sensor isn't operating

I would clean it as a process of elimination
Obivously I can't feel the performance but these engines do suffer from turbo /turbo control issues (vacuum ) problems

Also listen for whooshing noises on acceleration (splits in intercooler hose )as this can cause black smoke on acceleration
