Diesel Turbo down on power?

[Mr Plow]

Hi

Diesel turbo mondeo is down on power, I'm thinking the turbo has given up, a couple of questions?

- Can I still drive the car without doing any more damage?
- Best place to buy a replacement turbo?
- Is this something that a DIY mechanic can do himself?

Thanks in advance

best get it plugged in before you buy a turbo could be a sensor or turbo pressure switch faulty

Or an air leak.

Are you sure the EGR valve hasn't stuck or the bost pipe split, causing the engine management to go into limp-home mode?

Check the air hose, i had a guy who'se main hose had dropped off. wouldn't pull, heavy smoke.
not always a super complicated expensive job

What makes you think the turbo has failed? If it has then I wouldn't drive it, but as others have suggested there are numerous other faults that could cause loss of power.

Don't be too quick to jump at the turbo. If it isn't smoking or squealing like a pig, have a look at the MAF sensor. In the last 3 weeks I've had 4 Pugs with loss of power and 2 of those went into Peugeot for diagnosis with no results. They run off of a MAF sensor and a pressure boost switch as well as the MAP sensor but 90% of the time the loss of power is due to a faulty MAF sensor. It doesn't set off the EML on a lot of models and is easily checked without major equipment. Disconnect the MAF sensor located inline with the air filter housing and turn the ignition off. Restart the car and drive it testing for surge of power then loss again. It's known as limp mode to save damage to the engine through too much power being forced to it. If it tries to run nice, reconnect it with the engine and ignition off and start the car again then drive it. You'll notice the power loss straight away and saves big bills for diagnostics and even worse a turbo.
