Title: Low top speed on TD5
Post by: Landyman on June 17, 2010, 17:34:55
Just got a 2002 TD5 back on the road after a minor shunt but it wont do more than about 65 to 70 mph and flat out it is hunting like its got a fuel starvation problem.
I have changed the fuel filter and air filter but this made no difference. :doh:
I wondered if it might be a turbo problem?
It pulls well all through the gears just gets to 65 and won't go any more.
Any ideas before I book it into a garage for a professional and no doubt expensive diagnosis.

Any help or thoughts greatfully received. :huh:

Does it feel like the fuel is being shut off at that speed if yea have a look on discovery2.co.uk  he had a simlar problem and it's got very good write up on the td5 engine 

Also try unpluggin the mas air flow metter

Is the turbo waste gate stuck?

Can you move the lever/arm on top of the turbo?


Or is it in limp home mode?

I'm not sure what diagnostics system the TD5 uses but you can buy a fault code reader for about

Thanks guys loads there for me to check I'll see how I get on at the weekend.
definitely not in limp home mode as it flies up to 60 mph fastest Landy I've ever driven just runs out at 65 -70.
I'm going to look at the waste gate first.
where can I buy a code reader for

if its hunting then the ecu is picking up overboost so it scrambles the fueling to drop the rpm until the boost reach's the correct level.
td5's suffer with siezed wastegates
clamp a pair of molegrips onto the arm and make sure it moves freely
check the bleed pipe to the actuator for splits
if you still have problems, just lengthen the rod abit on the actuator
