Boost leak... Non saxo.

[CraigLovelock]

Anyone have any knowledge on TDi's :D

Tried a few forums but still trying for the right awnsers so giving this my best shot!

Got my fabia vrs a month ago, been great.

But last night it felt wierd. Started feeling like it was wheel spinning when turbo kicks in around 2k revs. It feel like it would lose grip and then regain. But it wasnt wheel spinning. The best way of describing it would be shudering...

The main thing is a loss of power! Now i know why non turbo diesels are slated!

There no power and its pretty much impossible to get over 3k revs.

Not clutch slip either tbh.

Cant really hear the turbo spooling as loud its just more of a lower grunty sound when revving (propaaa tracktooor stylieeee) and 'airy'.

My only idea is a boost leak as one of the turbo pipes has popped off possibly.

Ive checked them all and they seem fine but cant access sight to the lower intercooler pipe so thats the only other one it could be!

Just wondering if this issue im having sounds like a symptom of boost leak or... eeeek... turbo failure.

Thanks for any replies. I know its a long shot. Thank you for reading.

Makes me wonder why is sold the VTS!

Craig.

If there are no obvious air leaks from boost pipes then the blades on your turbo could be bent, it can happen over time.
Happened to my dads 307 and it needed a replacement turbo.

You make no sense... you said but without his whole post?

And oh... Now its gets expensive.

Guess its an excuse for a stage 2 hybrid turbo and remap :/

^He's just taking the piss lol.

Is there a whistle when the turbo kicks in?

It was a joke mate and it was also saying that I know fuck all about what you wanted to know.... I just like to increase my post count.

It makes me liked by people like Aly ya see :A: Jokes Aly! <3

Check all boost pipes over. Might be a vac leak causing it to not spool the turbo properly.

Although by the sounds of it more likely a fault with the turbo itself. Generally with the VAG engines and boost leaks you just get a hesitation. One of your boost pipes might have just popped off as they commonly do under load.

As said perfect time to upgrade to hybrid and remap it.

Thought it was best to check lol.

Any i dont know its wierd. Cant hear much noise anyway with the the diesel engine ha.

But it has changed more. Before it was a nice whilstle once it spooled up like, now i can hear it spooling sort of, but just sounds airy and no as loud...

Looking for like a fubared turbo :homme:

Out comes the bank card...

But i should welcome the 200bhp ha ;)

Try asking on UK-MKIV's, I'll have a word with my mate off their tomorrow when he is awake. He knows more about VAG cars than I do. He has also had his fair share of boost issues.

the pipe that passes under the engine i think it is has a habit of collapsing in on its self

[blakey260]

have you actually had the pipes off at the turbo? You're best of doing this to see the turbine inside, then jsut feel it see if it moves about (obviously spins unless it is knakered) but make sure theres no play, like someone else has said most of them these days are vacuum controlled so you need to check all the pipes going to and from the turbo and make sure none of them have split at all, best off having someone inside revving engine while your underneath or where ever listening, what we do at work is get a bottle of water with washing up liquid in it and squirt it on like a pipe for example if you think the leak is coming from there then it'll start to bubble up if it does have a leak. Has it thrown a engine management light on? because also if its over boosted then it'll put the car into limp mode and not use it at all safety to not damaging itself with too much boost, if you can't find anything wrong with the pipes i'd get a diagnostic machine on it to see if that says anything. hope it helps

Thanks for the reply :)

Im not mechanicly minded enough (or brave enough) to touch this stuff myself.

Im taking it to a friends garage tomoz to spend the afternoon playing around and trying to sort out this and some other issues.

Definatly need a VAGCOM check aswell.

Yeah no point replacing standard for standard

Exactly what I was thinking mate, check the shafts are intact.

[CraigLovelock]

Will check all.

Thanks for replies :)

Just to add, my MPG has been shit aswell since all this.

Would this lead more to a faulty turbo?

[blakey260]

what actually happened then? did if feel more powerful for a time being and then lose power? or did you just start it up one morning and it had lost power? garage i work in is a derv specialist even though im only an apprentice i do listen to some of the stuff they say ;) lol best thing to do is get it on the diagnostic machine, most ECU'S these days tell you every little fault, if its running in limp mode it won't run properly again until its memorys clear because it still knows of its fault, hope you get it sorted anyway mate, keep us updated on the problem

[CraigLovelock]

cant pin point a moment of change.

Just noticed it was being funny when putting foot down... then it got worse and now hardly drivable :/

Will keep updated. Thanks for help.

[blakey260]

sounds like a pipe has slowly come loose in that case, normally with turbos you can here them (like the turbine scratching against the casing) have you checked your oil to see if thats gone down? times when turbo goes it lets oil shoot out into it but if its guna garage tomorrow you'll find out anyway.

[16vax]

check the ic to i have saw some bursting or blowing the endcaps off and if its the pipes with the push in c shape clips the lugs on the pipes are bad for bursting off
colin

[sparky771]

sounds like you need a new turbo to me.

If you had a boost like you would hear a 'wooshin' when the turbo kicked in but only under load i.e. driving.

Could also be a crack in the side of the intercooler, cause iirc they have plastic ends whcih can sometimes crack.

but yeah just as a matter of cause id replace the turbo with the new hybrid turbo anyway if thats in your plans for the car. ;)

[pdb1985]

If a pipe pops off you would hear it, hapened to me once and its proper loud. As said before could be one of the boost pipes collapsing in on itslef therefor no boost.

[Matt-T]

Check the pipes for the turbo, cooler etc. If one has come off or got a split this happens. I speak from experiance.. I checked over all the pipes and couldnt under-stand why the turbo wasnt working very well, Was only when i got my cousin to look at the engine, i revved it to the turbo range could see a split in the pipe. Off boost the split wasnt visible

[CraigLovelock]

Update.

Garage today said it definalty feels like a blocked injector(s) and would be reasonable since i have run it low a couple of times last week.

Got some additive but wonderinf how long till it works!

Got it booked in for a fuel filter change aswell as a few other things!
