I was driving my Fabia vRS earlier and noticed that the turbo is coming on later, around 2500rpm, as opposed to it spooling up around 1700rpm, and hitting full boost at about 3500 rpm as opposed to around 2700 rpm ish. It then also cut out when I got to about 85 mph but came back on again after I'd restarted the car, this happened twice. Checked for oil spills or dripping and there wasn't any, nothing out the ordinary in the engine bay, anyone got any ideas?

Thanks

First thing to do it get it scannedforr fault codes. Then posst the results up here and we can try and help you out. If your near Croydon I can scan for you orr you can get a free copy of vcds from Ross tech and a cable is about £15 from eBay if you want to do it yourself.

Sounds like the vanes are stuck on full boost and it's overboosting and cutting out, check the actuator moves freely.

Thanks, I'll check the actuator, when it comes on boost, it comes on really strong and almost with a build up. Plus the car is a project car so isn't driven everyday and the actuator may be a bit stuck. Is a boost leak a possibility?

Not really.

Checked the actuator but could only do it applying finger pressure because I have no vacuum pump, the actuator is all the way up and on the Fabia is a BorgWarner I think, which means it's stuck on full boost so new turbo or clean it out?

Looks like its had a turbo failure at some point as the fabiad came with KKK turbos.

It could be the vnt mechanism that's stuck. There's a guide online using Mr muscle cleaner to free it up.

I thought that might be the case, hoped it wouldn't be though haha. Thanks though for the help

Borg Warner and KKK are THE SAME company.

Stop that ridiculous laughing, it just makes you sound like Chunk from The Goonies.  :sun:

Got cracking with it today but when I got to the pipe that connects from the exhaust up to the underneath of the EGR valve, I found they were stuck, think they've welded together slightly, tried knocking it and WD40-ing it and then mole grips but doesn't want to budge and it's starting to round, any ideas on getting it off? Impact wrench? Heating it? Not too sure on the best method. Doesn't matter if the nut gets damaged because I'm going to do an EGR delete anyway.

And of course, Merry Christmas

Thanks

drill/ grind. Is it the s shaped pipe from EGR to exhaust? If so cant you just remove the exhaust end, and remove the whole EGR?

Drill? Yeah it is and it's the exhaust end that's stuck. On an unrelated note do you have to remove the inlet manifold to remove the exhaust or is it just easier space wise?

first off is it this pipe?

Yes, the top end came off fine but the end that's attached to the exhaust is being difficult
