As title says.. Literally lost all boost/power, its like driving an N/A car.
Car has been mapped in the past by a previous owner, there is some sort of oil leak around the turbo area. Had a look in the service history and it says the turbo was replaced about 10k ago.. Possible it wasnt done properly?
Pulled into a car park switched it off, came back out and realised i had no power!
Any ideas guys?? (Will start a thread on my car, got it last weekend)

You need to read the fault codes mate :happy2:
Check the turbo and all the boost pipes over, turbo could have been starved of oil and failed maybe?

When on idle it is erratic and under load its a whooshing sound.. Very air'y

As above, scan for fault codes and check the pipework. May be the connection pipe from the intercooler to the turbo has come away due to a failed fitting which is common on these engines.

Done a scan today and nothing came up apart from p0036 (heater control oxygen sensor control circuit) which im guessing is from the fact its been de-catted?
Also got a OBD-2 wifi adaptor and the appropriate app and got a live reading.. Boost seems low.. This was gunning it in 3rd , as you can see there is a massice drop in power and torque aswel.

It is possible you need to replace the B1-S2 Oxy sensor. But the code could be resulting from something else undetected...but not likely. It sounds like it has gone into safe-mode due to boost plumbing leakage or cam follower failure or something. But you should have a more definite error code other than just P0036. Save this link to check any future codes...just enter the code in the search box: http://wiki.ross-tech.com/wiki/index.php/16420/P0036/000054

honestly its just like driving a 1.6 or something now.. terrible! That is the only code flagging up at the min, the cam follower failure sounds bad.. i ordered a cam follower should be here this week ( part number - 06D109309C ).
is it safe to drive? or will it do more damage?

Out of interest, which adapter are you using? Considering one myself.
Good luck with sorting the issue!

Check your pipes. Sounds like a boost leak
Irratic idle and whoosh of air escaping under boost

similar to that mate.. the app is called dashcommand

going to get a VW specialist to have a look this week.. aslong as i can drive it safely

Thanks. Ordered.

I was always told you cant read boost on the Gti through the Obd port!
I have a scangauge and it just reads 0 whenever ive tried it!
Also a cant see the bhp/torque being anywhere near accurate surely?

Check your Diverter valve too

If it is the cam follower...replace as quickly as possible.
If you do replace quickly...you have a chance to save the intake cam, but not likely going to save the hpfp. But this would only be a concern if your code reader isn't reading all of the codes because a cam follower failure would definitely pop a code. I would think to focus on the O2 sensor after you check the follower. Is your hpfp banjo or bamboo?
I have some DIY vids that may help:

Cheers mate .. Well i changed the diverter valve tonight, wasnt perforated but replaced anyway, still drives the same allthough the connector was soaked in oil from the leak.
Can an o2 sensor stop boost? Seems to be running wrong.
-
Many sensors can cut the power in order to keep it safe and to make you aware there is a problem.

Will focus on that then.. As for the HPFP the cam follower should be here today or tommorow so will look then, i had a quick look last night and it looks like 3 torx bolts and 2 metal hoses attached to it.

My DIY for the HPFP if it helps, but you all have the Banjo bolt on the high pressure side and I haven't ever dealt with it:

UPDATE:
Car is now fixed and back to normal.. the problem was the connection between the actuator somewhere, not allowing boost.
Leak was from a Banjo bolt on the turbo since it was replaced, guessing it wasnt tightened up fully.
boost is now back.
