b7 3.0 tdi fuel leak

[fulham4eva]

Hi all,

Finally got the car to start and run (kinda) .
If I leave the car to just idle on the drive it's fine but rev the car a bit and the entire street is smoke filled.
Also I tried taking the car round the block and it's completely gutless and of course can't see out the back window for smoke.
And about a minute after the car is switched off you can see tonnes of bubbles moving from the high pressure pump in the clear fuel pipe.

Lost patience with it so took it to a local garage who said the car is over boosting, he mentioned the MAF
They also mentioned a possible bad injector
And they also discovered what they describe as a massive fuel leak, they couldn't see where exactly it was coming from but seconds after starting it and looking in the bay, fuel was sitting in the gap next to the oil cooler.

So I thought I'd try replacing the high pressure pump, thinking the leak was coming from the bottom of it but there's still a leak and I have no idea what around there could be leaking. And too much air in system to start the car atm.

So any thoughts?

I think you have leaking injector seals from the injectors coming loose.

All injector seals and washers are new


Wee update

We've had the car going again today, had to jump it off another.

After a few tests I'm positive one or more injectors is playing up, so going to send them off to be properly tested. But won't get them back until the end of the month.

I've got vagcom which after a few runs and scans isn't showing anything helpful. I did find some measuring blocks which seems to have issue with 3 injectors being out of tolerance.

I'll see about changing the Map sensor and the MAF once I've got healthy injectors.

We also tried to find the fuel leak and strangely along the edge of the inlet manifold right side it's covered in diesel, and doesn't seem to be sealing right

definitely don't have that going, both exhaust manifolds are very clean.
I mean we have diesel on the edges of the black plastic inlet manifold right side.
So going over there to remove them and see about replacing the gaskets, why fuel would be there I have no idea???

But once there off hopefully I can see that area a bit better

I'm also going to see about blanking the EGR and removing the swirl flaps
