406 hdi 110 slow/underpowered

[stoney]

Just bought a 406 110 hdi estate and it seems to be pretty slow/underpowered, its pretty driveable as it is but no feel of turbo kicking in and really sluggish up even the slightest of hills.

I was left standing by a 405 1.9td estate so I think summits up!

Certainly shouldn't be like that.

Is the EML light on / any messages on the MFD?

Worth checking the fuel and air filters, also look for any boost leaks / check if the hose from the intercooler to the manifold goes hard when you blip the throttle.

after sodding about for ages trying to find splits in vacuum pipes, checking filters etc etc I finally found the problem to be......a slack throttle cable!

Slack throttle is a common cause and often overlooked
Hows the car now?

Car drives bloody brilliant now, like a totally different machine! still got some electrical gremlins to deal with might need to hunt out someone with some diagnostic gear

Add your location to your details and maybe someone local can help.

When I got my first 90, I spent ages looking for the reason why it was slow - turns out its because the engine was too small for such a big car..

I've been wondering why mine is slow. Thanks for explaining why; it's been bugging me for over 8 years!

I had a Xsara HDi 90 estate many moons ago, but concluded a 406 could do with a little more urge
