hesitant 407 hdi

[carpeys]

hi everyone,newbie on here,just bought a 407 sw 2.0 hdi,runs great except when cold more noticably,its a little hesitant on a light throttle and not too smooth,if i increase the throttle position for acceleration it pulls fine,anyone have an idea what prob stems from,its not too bad when hot,but i still think it should be smoother ,its got fsh and done 107 thou miles,57 plate,thanks paul

Try a drop of Redex

[CAB]

This is becoming a common problem on the 2.0hdi's.

Like Betty say's redex or millers won't hurt.

Most likely it will be egr related.

ive got pretty much the identical problem, but im wary of using redex, i have heard bad things about it, like eating up seals on the injector, power loss etc, i've even heard people compare it to snake oil..

I`ve 2 treatments of redex in this past week .

Most of these engines take software updates for the egr problems. I know it means going to the dealers but it'll save alot of hassle.

It only eats up seals if you put in two doses a week.

My Peugeot master tech said that it is alright to use so long as its a recognised brand.... apparently Pug do their own one specifically for HDIs if you're worried about the other brands

Back to original problem.... mine used to do it, still does at times.... as David said, I had software update (which meant new EGR) and it did help it for a while, but its back there again now. Like you, gentle throttle and it does it, but give it some beans and it'll go like a train

[battlestar]

The software update doesnt sound so permanent then, is it something that is updated on regular basis, or only when they really fix some 'bugs'?

Good question

You would think software update is permanent, but unless its the EGR starting to play up again, who knows
