Yeah its on the front. Look like its been hit by a stone

[dave_mito]

well put a brand new oe intercooler on. Its now pulling much better, but still got the maf fault.
The engine will cut out now if you block the air intake, unlike before whilst it just breathed through the intercooler.

I now get a hissing noise behind the dash for about 5 seconds behind the dash, could this be connected??

Any actual running probs now other than the light.
have you tried erasing it...


if you look down by your foot pedals you'll see the steering link and rubber boot. is the boot correctly in place?

Seems to be running ol when the light is on. But when i clear it, its tunning rough until the ligjt vomes back on.

The hissing is coming from higher up, around the centre vents.

It was running spot on in the workshop giving good maf readings at ideal. But once I goy a few miles down the road and put it im boost it suddenly went flat, as tho a boost pipe had popped of. Whicj it hadn't

If the boot isn't fitted, it farts when you go from lock to lock (from experience lol)

Hissing from behind the dash... possibly the collar that joins the turbo to the OTE pipe, leaky recirc valve, leaky actuator or actuator pipe.

OTE pipe??

only does it for the first few seconds, is there a vac pipe that closes of after a few seconds. Thinking some one could of tee'd of that for a boost gauge

[M-R-P]

Over The Engine pipe.

You can't tee off the actuator pipe but the recirc pipe is the preferred pipe to use for a gauge.

I could possibly be the recirc hissing while the boost starts to build and then sealing. Any chance of a video of the noise?

I'd start checking/changing all the vac pipes, especially the one on the compressor housing.

[dave_mito]

its just strange how it does it only at start. Its defiantly louder in the car rather than under the bonnet.

[M-R-P]

There's no pressured air system inside the car but the turbo is very close to the bulkhead and can give the impression that it's near the dash.
A good example would be the OTE pipe - if it had a split in it, at the first corner above the turbo, there's not a lot of soundproofing between the pipe and the windscreen. You'd hear it as a hiss coming from the windscreen vents.

[dave_mito]

will check all the vac lines later today.

its a good job the car is so nice to drive and practical, I would be getting annoyed with any other car by now lol

[M-R-P]

Look for wet patches around the connections for the big boost pipes, it's an indication of a leak.

all boost pipes have been of, cleaned and re fitted. so don't think its coming from one of them

[M-R-P]

Were they refitted correctly?

Not taking the piss, simple solutions first. And, if they've been cleaned, any leaks will show up nicely. It's possible to get a pipe slightly out of square when you can't see it properly when fitting it, I've done it myself.

double checked them last night, that's the first thing I thought.

I need to block the intake of a pressurize it all up and listen for leaks me thinks, need to come up with a way to get a Tyre valve sealed into the intake

[M-R-P]

Use an aerosol cap with a valve glued in and jubilee clipped on to the compressor inlet. You'll also need to block the pcv outlet with something like a cork.

[dave_mito]

well the hissing noise is the ac, must turn on briefly when started. drained it out yesterday to fit the coolers.

Cleared to code again, will see how it goes tonight.

[dave_mito]

code come back.

Think im going to make a smoke leak detector and see what I can find from there
