Mines been doing this since I got it. Now on 62k miles had it since 29k. Wondering if a preventative & planned turbo replacement is a good idea.

Hard to tell if it's getting worse or not! Last time I asked a garage (VW Specialist) they said all the PD140s do it!

Had my car cooing/sirens since 06 touch wood no turbo issues @85k.
I actually think I would miss it.. :)

Mine spat the dummy out on the 22nd.. Driving away from the house came out of the junction and as soon as I boosted in 2nd gear the car jolted.. it sounded like a driveshaft had snapped and lost power and literally left everyone in a cloud of smoke.

After I limped off the main road and back into the car park I was going to re-try the car to see if stopping and restarted reset anything as the boost gauge seemed to show some a hint of negative vac just when blipping the throttle so I thought maybe the turbo was ok. As I drove out my other half thankfully chased me out the car park to tell me that I was dropping oil so I parked up again and put a container under the car to catch all the oil.. which as it turned out didn't even cover the bottom of the tub. After dipping the car there was a mere trace of oil.

Fixed now though and collecting the car on Saturday, New turbo, oil return feed pipe, intercooler pipe etc.

Now I don't know if I want a whiney turbo! I still don't know if that was related or not but after reading up on this problem is seems very common. Turbo warranties are only upheld if the oil return feed pipe is replaced so this is possibly a big part of it.

Does the oil return feed get so clogged that it just builds up pressure in the turbo?
Would changing the oil feed pipe have prevented this?
Unfortunately I now wonder if my 2 mile city driving is really damaging to my car!

Bought my pd140 with very low mileage at 23k and by 30k had an AMD map. it had the owl noise at low speeds/low revs when backing off the throttle etc from the start but at 46k it turned into a very camp, very loud police siren when going on and off boost and it sounded completly shagged.

Got it inspected and it was knackered. Got it replaced with a new standard turbo and after about 2k of driving the quiet low rev owl is back. Just happy SEAT have a 2year warranty of the turbo.

Just picked up mine from getting the Turbo sorted, was playing up and went when the mechanic was looking at it thankfully so they stopped it before it did any damage. Just turned 80k, was noisy for the last couple of years but had got really bad of late

Mines had this turbo whistle sound that makes me think theres police sirens behind me!!... I've asked a few guys now and they say its normal.. so I hope it is. Was having my FR remapped last week but had problems with it so going back now next week... hope its not the turbo thats the issue!!
