Jammed turbocharger – Burning excessive amounts of oil, slow acceleration and excessive grey coloured smoke are the typical signs of a worn-out turbo. The longer your drive your vehicle with a failing turbo, the more damage you cause to your engine and therefore the most costly it will be to fix.
My car was making a weird high pitched noise, started to lose acceleration so called out the AA the guy said it was a problem with the turbo, he played with it, the noise stopped but acceleration was still slow, the next day it (today) it started to give out blue smoke, does it seem the turbo needs replacing, can I ask a rough estimate to replace! Thanks.
