is my turbo gone?

[flatyre]

hi all I just bought a 2005 1.5 dci megane for the wife, she wanted something French against my advice. Anyway instead of just paying the normal price for a decent motor, I picked up this one for half the going rate as it was described as being 'down on power'. It drives well but doesn't have that turbo pickup, it feels a bit like my berlingo 1.9 straight diesel, powerful enough to get about but still a bit lacking. There is no sign of any smoke, though its a bit lumpy on tick over and when being switched off, though never having owned one before I can't say whats normal or not. Does this sound like a knackered turbo and if so whats the repair costs? thanks

First thing to check on a 1,5dCI is the EGR valve, it may need a clean up.

This, they're about £30-40 for an aftermarket replacement on fleabay.

cheers guys, a mechanic I know had a quick look at it an hour ago. Diagnostics showed up a fault with the drivers seat belt buckle which explains the air bag warning light, but no engine faults. He floored the accelerator in neutral for a few seconds and it started to throw out quite a bit of black smoke, his advice was to make sure there is plenty of oil in it, then rake the life out of it in third, "it will either blow up or clear itself"??? don't know if this sheds any light on the problem but he doesn't think its the turbo.

Sounds like an intelligent mechanic.

It will probably take less than an hour to remove, clean up and re-install. There are even videos on youtube to show how its done.

Carb cleaner and a toothbrush

ETA: Take off as much of the inlet pipework as you can and clean that out as it will be full of crud.
