    1.9 tdi sport losing power at 3k and smoking a lot!

    Changed air filter, oil and oil filter today. Also found a vacuum pipe that was worn and I think had a tiny hole in it. Replaced that and it's running lovely now! Now to clean it up tomorrow and get it up for sale. Shame to be selling it now it's running so well again!

    Great stuff! It seems like a big leak. Fairly loud hissing noise. Hopefully I'll find this and it will sort my problems tomorrow! Ill report back

    Ok thanks for your help mate. I'll see if my mates free to check that for me. Do you know if the pipe from the anti judder should be free to blow through? Ill look into it further tomorrow. I'm hoping this is where my problem is! I've bought a transporter so will be selling the car but I just...

    Sorry it was the vacuum line to the anti shudder valve I blew down

    1.9 tdi sport losing power at 3k and smoking a lot!

    Ok just been for a quick look at the car. When I put a new hose onto the top of the actuator, I could suck and feel the rod coming up, then returning back down when released so I'm assuming this rules out sticking turbo vanes and leaking actuator? When I disconnected the vacuum for the egr and...

    I could pull the actuator rod up, but it did take quite a lot of pressure. Not sure how hard it should be but it was pretty hard. And would spring back down when released. Think I've got some pipe here for the vacuum lines so I'll replace what I can tomorrow. I'll also speak to my mate with vcds...

    I did give the turbo a clean with mr muscle a few weeks ago but made no difference at all.

    Yeah I've got an a4 1.9 tdi. This account is my brothers old one. Oh so a coolant temp sensor could be worth trying then?

    1.9 tdi sport losing power at 3k and smoking a lot!

    It's having oil, oil filter and air filter done tomorrow, so while we have it on a ramp, were gonna check boost pipes and vacuum lines to see if there's anything damaged. From what I've read about that fault code, it seems it's either vacuum lines, actuator or sticking turbo vanes. I just...

    1.9 tdi sport losing power at 3k and smoking a lot!

    I thought coolant temp sensor, but wouldn't of thought that would cause issues this bad. My mate scanned with vcds a few weeks ago and no codes came up. I drove it to London last week and after being on the motorway for a while, engine management came on so my mate plugged it in with a generic...

    1.9 tdi sport losing power at 3k and smoking a lot!

    Changed the maf Wednesday evening and it seems a little better but definitely not right. I've noticed that the last two mornings, if I put my foot down from cold, it pulls fine in all gears up to 4k no probs. then as it starts warming up, second gear is fine but third loses power and smokes...

    Well today I did the mr muscle on the turbo and its still the same! I'm sure it was only a couple of weeks after the map that it started so I may contact who did the map and ask them

    Had it scanned with vagcom last night and it didn't show any codes. Well only signal too low for my air con sensor. It could do with a service so ill do oil, oil filter, air filter and fuel filter. Ill also do the mr muscle on the turbo and see how it is after that.

    No I don't. This is my brothers old account. I've gotta set up a new one. It's a 1.9 tdi a4 avant sport.

    1.9 tdi sport losing power at 3k and smoking a lot!

    What should I be getting checked with vcds? Is just a full scan likely to throw any codes up? Or do I need to look into more? What would people advise checking while its plugged in?

    I cleaned the egr about 6 weeks ago. The engine does wobble about a fair bit on idle so engine mounts will be worth looking at. Ill try have a look later and check boost pipes again

    On my way home today, I decided to try unplugging the maf just out of interest. It didn't smoke but had no power at all. It was really slow. But idle seemed a little smoother
