Hi I have noted a very similar issue when 'tickling' the accelerator to maintain a speed above 50mph or even as low as 30mph. I have read a lot about it.

 

Unfortunately there are a number of things it could be, injectors, injector/glow wiring harness, MAF sensor, throttle position sensor, throttle, turbo, waste gate, ECU remap... The list is endless, take a look at the forums for Mk5 golf or scoda Octavia, any car with the vw of engine (bkd) there are a few other engine codes similar but ours is ECM according to Chrysler but really it's a bkd..

 

I have changed a number of parts and still suffer from it, only thing close to a cure I have found so far is to run the engine hard for a few journeys, like you stole it. But after a short while it's back.

 

If you do find a cure for it, PLEASE PLEASE PLEASE post it in our forum :) it is a frustrating minor problem people seem to have to settle with...

Good luck!

I'm feeling its like the engine is being starved of fuel, had an issue after changing the fuel filter where the ring that holds it on and the seal broke ..go figure but it was doing very similar thing. I will have a look to see if it is the fuel injector, I have had it remapped but that was 2 years ago and I has never caused an issue. I do feel the car lacks any real kick when the turbo normally kicked in at the moment.

Ahh, I haven't had mine re-mapped, so that crosses that off the list (did the remap do much good?), and mine started before I changed my fuel, air and cabin filters and didn't get any better after.

 

But I doubt it is fuel related, if I put my foot down it stops, if I come off the accelerator it stops. It is just when trying to maintain a constant speed. Like I say it seems very common for the engine and no one thing seems to fix it, infact I'm yet to see someone claim to have fixed it.

 

Mine feels a bit slow at times when the engine is cold, and the turbo does seem to be a bit delayed but when it's warmed up Ive never felt disappointed with it.

 

It's a nice car, I love the rareity of it and all the luxury features, (I have the 2009 with mygig touchscreen, heated seats and all the trimming) so I'm determined to keep it running well above 300k miles if I can, my wife hates it though

I found the remap gave better acceleration and better mpg all in all very positive.

I think I've narrowed my problem down to a faulty MAP sensor.

Ive also bought a egr blocking plate (under a tenner so) just incase that is also an issue so will see what's what soon enough.

The car still has a lot of stock parts on it considering it's 10 years old.

Genuinely think my heads been up my arse the past 2 weeks.... 

So had some peace and quiet to have a good look around, noticed the hose that goes straight into the turbo has a huge cut on it, couldn't see unless I looked at the hose that runs over it was covering it partly. 

You know the hose that's like on the right of the oil dipstick is that the intercooler hose? (goes straight into the turbo).

Dead centre of the engine? Quite a large diameter hose? If so yes that's from the intercooler, I have blown mine a few times, if you search eBay for a jeep... Patriot? Maybe... Intercooler hosei got one from Poland for under £40 reinforced it with heat resistant silicon tape. When you have it off it's a good time to look In and see how gummed up the intake side of you engine is. Untill your replacement arrives duct tape, super glue and cable ties and driving a little more gently should get you by.
