Hi guys. Less than a week into ownership of my 1.9 JTD and my second problem has arisen. I think I may have a turbo issue. Car has been driving fine, but last night, lacked power on pull away from junctions and low speed manoeuvres. Doesn't pick up at all until approx 2500-3000 rpm, when it takes off like a scalded cat.
Before I book it into a garage and no doubt get a load of waffle, are there any generic issues or common problems I may be able to diagnose myself?
Also as a second part to my question, can anyone recommend a decent fault code reader that is compatible with my 2003 vehicle? I see loads on ebay, but they vary dramatically in price and no doubt quality. Thanks in anticipation.

when my lower pipe went boom, it was making a hissing noise. if you cant hear the air rushing out, could just be the egr valve??

Thanks guys. From the service history, seems it has a new silicon lower turbo hose a couple of months ago.
I love these forums. A wealth of information at your fingertips. Such knowledgeable and helpful people!
Anyone recommend a good code reader for this car?

You could always pop it in on a Sat for the free check over - would obviously read the codes for free. Bit of a trek though I know

I would check the top hose, both my JTD's had a split on them.
Just pop out and feel all around it for a split. It's worth a shot and its free.

if when it takes of it leaves a black cloud its egr sticking

your turbo is 100% fine........it could be a leaky hose but it wouldnt do as u described,picking up all of a sudden, if the actuator wasnt moving properly it wouldnt suddenly pic up

Thanks again chaps. Some very useful info. I'll be checking hoses, boost controller pipes, egr valve and not to forget the intertrigronic output placator beacon sensor actuator hysteresis modulator, just in case it's got a bit tired.

So I cleaned the EGR valve properly. It was as clean as a new one I reckon. The solenoid was free and I couldn't find anything obviously wrong except of course a build up of sooty carbon deposits as expected.
As suggested I have also checked all the turbo hoses and can find no damage at all.
Generally when driving, it's as flat as a dab until 2-3000 rpm when off it goes, often with the cloud of black smoke. Seems intermittent as occasionally it pulls through cleanly.
Seems likely that I will have to swallow the cost and replace the EGR Valve with a new one, but can someone tell me what benefits I get from it? Is it relatively straightforward to delete it, and if so, why wouldn't/shouldn't I?
From others posts it seems like these fail frequently. Will the emissions be unacceptably high come MOT time if I remove it? Does the car require specialist re-mapping if done? I was booking the car in with a top tuner to have it rolling road tuned, but don't see the point until I get it running properly first. I don't want to be paying for his time just to get it running properly.
Sorry it's a long post with several questions, I'm trying to pre-empt the more obvious responses. All views on EGR removal would be welcomed guys.

get someone to start your car as you look at actuator rod on waste gate actuator(variable vane) you should see it gradually move about 20mm ,if it dont you got leak in small bore pipes

Start car (or better get someone else to start car) and watch for vgt actuator you want to see it move about 1cm or a little more and for it to move back when switched off. it would behave like that with vac leak or vgt mechanism or solenoid problem because the turbo would not switch to small mode and only come in later up the rev range. Eg 3000 rpm

Carefully check hoses again when I changed my top hose I could' t see the split or feel split even when off car, even wiped it clean still nothing. squeezed hose and suddenly I could see massive split on underside...

Yeah egr may not be working... did you just clean what you could see or did you follow the guide to clean the rod that runs into black plastic bit?? If just cleaned what you saw then follow guide to clean egr as it's often the rod that gets dirty and sticks.

Clean the VGT actuator and grease it.

Clean MAP while your at EGR, other end of intake manifold small black unit with 1 bolt.

Let us know what you find...

If you get a judder on switch off that would be something else that would point to vac leak in vgt actuator pipes

I had this problem a week after having mine and it was a leak in one of the vacume pipes.... it looked ok but had gone a little hard on the end of one of the pipes I changed them and all well :)

p.s i used nice red silicone pipe, looks good and also easyer to see any damage :)
