OIL LEAK! pipe near turbo or diverter valve??

[EyeballPaul]

Got my car back today, all they have done is changed the same small pipe again that the seal failed on last time. So it has taken them a week to speak to VW UK and al they have ended up doing is a 1 hour job this morning.

Im not convinced this is the route of the problem, but i have already arranged a part ex deal for a John Cooper Works on the 12 Jan. I cant be bothered going round in circles with this problem.

i must admit i cant blame you

nothing worse than going back and forth to the dealers with problems on a new car.

So over the past few weeks I have been noticing small irregular RPM at idle and small loss in power. So i popped the hood, engine cover off, and spotted oil near the filler cap and PCV valve.

So did the classic check, remove the dip stick whilst engine is running, didn't even flinch a bit, which in my past MK5 GTI means the PCV valve is shot.

Sent the pictures and a short email to my dealers and they confirmed Yes, its probably a PCV failure, got in next day to have it replaced under warranty. Only took them 20 mins to fit the new and off i went. It has instantly removed the irregular Rpms and full power and boost has resumed. So gave the engine bay a quick detail to remove all the old leaking oil. Now looking pretty good for a 5 year old engine bay.

You can see all the leaking Oil




Now all cleaned up and looking tons better

59 plate GTI , leak coming from near Turbo , dealer has suggested sealing it up the leak somehow or else replacing the turbo , they said the would usually do this before replacing the turbo as it's cheaper !
Anyone head of this course of action ?

[RocketRossUK]

Smell like bullsh!t.

Where abouts near the turbo?, do you have a picture.

Oh fiddle sticks its back!
Just on this pipe though. (Better pic of pipe on page 1 of original leak)
cleaned the oil off it 2 weeks ago and its back again.
So need to pull the diverter valve to have a look.
May actually be this pipe built in mounting bracket causing the pipe to weep. (Most likely cause)

Anyone know the part number for this pipe and cost?

After a bit of help i have got oil around the intake pipe and been getting spluttering at low rpm but i have done the oil cap test and my revs are dropping is this my pcv or something else???

VW picked notified me of an oil leak near the turbo that they found whilst carrying out the MOT said it needs investigating.

I've not had chance yet to have a look but will try this week.

If I have to pay for this how much roughly are we talking?

Get them to show you before you do anything. Most small oil leaks on the TSI engine are easy to fix.

Usually a worn DV Valve, worn PCV valve, or a the breather hose on the intake needs securing on properly.

Give us more info when you have it. PS an indy garage will charge you about £30-£40 to have a look for you.

VW wanted me to book it in for further investigation but think I will take it to a local Indy first. Will let you know what they say
