I would suggest whipping the fuel filter out and having a look then, see if there is any metallic particles in there. If so, would definately indicate an unit injector failure (or approach to)

Cheers Rhyso mate, that pipe that was leaking was under the driver side front near the bumper but you'd need to look at it from underneath.
Toph put that back together as it was loose and my MPG went up for a few weeks after my service and fuel filter change butt looks like with that fixed and secured it may have moved to the next weakest link which may be the intercooler.

The intercooler is being checked next week, the MAP sensor will have some logging also.

Fingers crossed once it's all stripped around that area to inspect/change the intercooler if needs be then we'll have a clearer picture of the problem.

Nothing ever shows up on Vagcom with my car for some reason :(

Regards to this question, the reason I ask is because the car stutters quite a bit now in the mornings like it's got low revs and needs a bit more, yet the rev needle sits still and on 900k as it should.
The car also judders on idle now and feels/sounds like it's missing a beat sometimes :(

Car deffo got less poke also and that's with the map.

As per my previous post.

I would suspect that at least one unit injector is beginning to fail.

I'm hoping that aint my problem as it looks like it's the intercooler or boost leak in that area fingers crossed.

~£100 each.

I thought the boost leak had been ruled out. I would hope it was that, as pipe is usually cheaper to repair.

Well it's a possible boost leak near the intercooler, the pipe that was previously loose at the bottom front of the drivers side is now secured but may have moved to the next weakest link which may be the intercooler or i'm hoping a pipe near there somewhere.
I've not checked yet cuz i'm going to see Toph on Wed next week to have a closer inspection on the said area.

By Toph's work so far it's looking like it's either a leak around that area or a leaking/fooked intercooler.

As said before the info on the injectors was to try and understannd if any of my injectors were fooked and if there was an easy way to tell if one or more are fooked.

£100 each ouch, car will be going on the trader if that's the case.

Aye, easiest way would be to have a look at the fuel filter then. Ask toph to have a check when you get there, and it should be quite apparent if there is any metal in the filter.

The good thing is you should be able to take them out and detemine which one it is that is breaking down, so will minimise the cost to you a little.

You can normally pick up a set (4) of 2nd hand ones for around £150  :smiley:

If it is your intercooler then it must be well shagged   :sad: as even with a dodgy one on mine, 500 miles to a tank was a doddle and also there was no boost loss showing on my boost gauge
