my 03 2.0lt 110hdi has been playing up had no power when turbo kick in 2000 to 3000 rev been looking at it to day and i had a play around and remove the inter cooler and replace it with some pipe that had a t in it to link up the plug on the intercooler

i went for a little test drive and all runnig good

what would happen if i drive the car like this untill i got a new inter cooler i drive 30 miles aday for work would this kill the car .

You wouid have to drive the car steady mate,
withought the intercooler, you couid cook the turbo id think, imight be wrong there tho,

whats wrong with the intercooler?
where you getting any woosh-ing noise with it on ?

i had no power and and sometime i felt like the engine was lacking something.
it sounded like it was histing all the time so i think the inter cooler has a hole in it somewere

An intercooler is there to cool the air going into the engine to make it more dense to aid combustion.

Cool air is more dense and burns better.....maybe you notice on a cold, wet day that the engine seems to run better....cold, dense air is the reason.

it all started when i notice i had turbo lag the power was kicking in at 3000 + REVS then a day or two i only had power 0 two 2000 revs and then the power some times kick in above 3000 revs it was not pulling at all link it up to pp2000 and said the maf meter was reading wrong / faulty and turbo boost was wrong or faulty i need to redo pp2000 but as it was raining all day i could not take laptop down to car as i live in 1st for flat most of my driving is in 30 to 40 mph speed limits

it been cold and wet most of this week and the car is sick i would like to replace the inter cooler.but i dont want to spend a lot of money out on the car as i was think of selling it to get some different that had 4 wheel drive and can handle roads that has lots of pot holes and hills (ie a ralley car ) land rover

Take intercooler off, fill it it with water,
if water dont pee out, dry it out put it back on,

Might save you a few quid,
idont know any other way of preasure testing them, Anyone else know?

Iwonder if this wouid work, (Inter-cooler preasure test)

Here the list of ingredients needed,

1 foot pump with Gauge,
2 x jubilee clips,
1x Bmx inertube,
1x pair or scizzors to cut bmx inertube,
1x puncture repair kit incase the liberated bmx intertube is punctured


wonder if thatd work

I'm sure someone's breaking an HDI on here...

I don't think running it without an inter cooler would have any adverse affect other than a slight dip in power from the turbo, isn't the HDI 90 the same turbo sans intercooler and a different engine map?

Saying that I drive a 1.9td so don't stake your house on that.

I'd be tempted to give Lozz's suggestion a go.

hope this can help with working out what not giving the car any boost untill after 3000rpm

Suggest you clear all the intermittent faults and see which if any come back. The turbo pressure low one would fit with a boost leak or MAP sensor problem.
