New Turbo Really Loud Turbo Noise

[paulr26]

I recently blew my turbo, infact it snapped in two . Anyway had a new one fitted with new clutch and changed the CAT.

I now have the usual turbo spin up. At 2500 revs and above I hear a really loud noise like the turbo is screeming. The noise goes after about 3500 and also if i lift off a bit.

Anybody know what this could be.

Yep i was the same when i had my new hybrid turbo fitted on my ibiza fr. Aparently, all it is is the turbo sucking the air in, you will also notice it more now because you have the new cat aswell. If it is a sports cat then it will be louder because it is less restrictive. If it is just a new standard cat it could be because it is new and kind of like the sport cat, less restrictive.

It is a standard turbo and CAT.

trouble is that after about 100 miles driving the turbo starts to shutdown I have intermitant power between 2500 and 3000 revs.

When the noise happens you loose power. Does anyone think it could be a pipe? and which should I check?

it sure doesn't sound right (in either instance)

if it didn't do it before, it shouldn't do it now.

Was it a warrantee replacement?

 

[paulr26]

It has done 66000 miles so not warrantee job.

May take it to SEAT Dealer to check over. Another garage fit the turbo not 100% sure now they have done decent job.

sounds like something isn't right.... maybe a gasket blocking something?

funny you say that. I did check the turbo pipe connector at the bottom of the engine near the front. It looks completly different to how it did before.

The other turbo had a clip around the pipe, the new one has all sorts of gunk around it and no clip. Also pipe looks thicker.

I think maybe only option is get it back to SEAT Dealer. I know they are expensive but they know the car.

One good thing. I haven't paid the other garage for the turbo yet

at the pipes on the TDI should have the clip.If all the pipes are OK (doesn't sound like it), it might be one of the vacuum lines to the VNT actuator arm.

Can i check that myself or is it a garage job?

I would check for anything obvious, but will probably need to get it checked by professional.
