My x reg td4 has lost a lot of power. It now seems to have to get to over 3000 revs before the turbo kicks in. It used to be about 2700 before I got an injection of power, which itself was a bit painful, but now I'm having to go down to 2nd gear to get up the slightest of inclines. Any ideas? Thanks in advance for help.
Has this loss of power has been a gradual thing? If so, perhaps you need to attend to the air filter if you haven't already done so. If this is ok, they I would suspect insufficient fuel delivery problems.
