hdi holding back

[ashgtir]

hey all ive got myself a d9(i think its an 02) 2.0 hdi
when i put my foot down at say 2500rpm the car pulls like a train but as soon as it gets to about 3000 and a bit it goes a bit flat.
anyone had this before?
cheers ash

That's the way they are apparently - something like 3000 or 3200rpm

I can't say from personal experience as mine has been remapped, and pulls throughout the rev range, so maybe that's an option for you to look into if you want more oomph

[ashgtir]

ok fair enough remap it is lol. what remaps do people have on here?

[lozz]

What Hdi do you have ?
is it a 90 or a 110 bhp.
or correctly speaking is it a 89 bhp or a 109bhp ?

Hi Ash,

I'm guessing you've always driven petrol cars?

It's all about the torque with these, mine is certainly happiest in the 1800 to 2500 rpm range, I rarely take it over this as it's just flat like you say.

I think it's just the way they are. Oddly the tacho is redlined at 5500 rpm!

[ashgtir]

yeah petrol turbos lol
but ive had a 405 d turbo and a 306 d turbo guess it must be because its a hdi?
its a 110bhp.

[lozz]

if its a 110 its shouid be pretty good on power,
Maybe something is holding it back,
what does the clutch feel like is the pedal light

Hi, I have a 2.0 HDi 110 BHP and mine is sluggish up to 2500 rpm and then the horses kick in and away I go, don't know why though.

how far does it have to be revd before you can hear the Turbo whistle, ?

[ashgtir]

The turbo whistles at about 2k but I only notice this most in 2nd gear.

Ah "Nowt wrong with that then,
Maybe your not used to the Gearbox yet once you get used to the 110s gearing you can get them to fly,
or Get it Remapped its worth it

Defo a problem as I took it out last nite and gave it the beans an it went like a rocket no holding back and boosting well into 4000rpm and again this morning but went out in it an hour ago and my flat spot is back.

[lozz]

Might be worth changing the fuel filter and air-filter,
Mine went a bit flat on power the other week and idrained off the fuel filter bowl and it had some crappy looking yellow fuel coming out its been ok eversince

[ashgtir]

Yeah might give that a go and see what happens.
