Freelander 2001 td4 195k
Hi, thought I would offer up a solution that I have found on my TD4 that had lost all its go..
Symptoms were that anything like a hill, then no go at all, down to second and just get out and walk faster. No smoke, no whistling pipes..just nothing. Read up on turbo replacements, actuators, intercooler leaks..( scared meself to death..) the cost of any of these and might as well weigh it in for parts.
So to the point. At the fourth dig around in the back of the bay, noticed that the hard plastic snorkel pipe down from the airbox had come a drift..(?).Surely not that..but the amount of time Ive spent in there could easily have been knocked.
Secondly noticed on the turbo actuator solenoid there are three spigots, No 1) I think should have the filter attached (that thing I have never found in five years, but now I know) No2 goes to the turbo actuator, ok..however pipe No3.. travels all the way across the top of the engine to some sort of air box on the other side of the bay. This pipe looked ok, but when I pinched it, it crumbled to bits.. Nicked a piece of fuel line from my P38 ( bless her) and replaced both rotten ends with new and used offcut copper brake pipe as joiners.
Result!! Don't actually know what the pipe does, but the truck is back to its rocket self.
Lesson learnt. Don't always think it's the big expensive parts that are the problem, sometimes..etc etc
Hope this helps someone along the way.
Cheers
 
The pipe is the vac feed to the boost actuator. If the vacuum can't reach the actuator, it can't swing the vanes to increase the boost. ;)
