Moved to the Diesel section for better response.

 

Thank you! All a bit rushed as I literally put a deposit on a caravan yesterday!

 

@mattydyer
It could be a few different problems all relating to the intercooler, the loud pop and the engine going into limp mode.

1/ The limp mode is probably caused by the engine producing to much boost and could be caused by the following items.

2/ Boost band clamp come loose or broken.

3/ The aluminium boost pipe split / broken.

4/ One of the silicon flexible pipes split.

5/ The actual intercooler could have split, cracked or come apart at the seams.

The attached screen shot will assist you, but feel free to ask any question and I will endeavour to help.

 

As kev said they are the probable outcomes, me personally, I'd go with a split boost pipe or intercooler.

I picked up a brand new aftermarket one for about £130

 

Great news thanks.ill dig a bit deeper when I have more time tomorrow at work. Thanks for the swift responses once again I'll report back tomorrow night!

 

Pardon our interruption...

Get the fault codes off the car too.

 

I've got a Bluetooth plug and torq app so I'll get them tomorrow night.
Does the bumper need to come off to get the intercooler out?
I've so far removed arch liner battery and tray and the airbox pipes from above and a couple of clips to pull the lower black plastic part of the bumper off slightly.
Whats next?

 

I took mine off just to make it easier. My Torque app would give me weird non honda codes (like electronic steering pump , which we done have etc)

 

Remove your nearside inner plastic wheel arch, it opens a whole new world and gives you much more access.

 

Yep, done that and a couple of clips holding the lower bumper on to try and pull it forward slightly. Just left it at loosening (what I think is) the top intercooler hose under the battery tray and air filter feed pipe. On hold till Thursday night now unfortunately.
Are there any retaining bolts/screws holding it in or is it a case of removing pipes and wrestling it out?

 

Yes, you must undo the top end pipes / clips as part of the removal process.

 

UPDATE
Intercooler is finally off, after much swearing, shouting and bloody knuckles!
Apart from been covered in gunk, the only issue I can see is the orange (rubber) seal that is hanging low???
going to try and give it a good clean at work prior to finishing for the xmas break but does that look normal?

 

The orange seal means your intercooler is blown I think.
I couldn't see the orange seal on mine when i changed it, i only found out it was leaking when i tried cleaning it with paraffin, and it was leaking out the base. (If fluid leaks from it, air definitely will too).

 

Thanks. I cleaned it off a bit with water based degreaser and it was,leaking out of there. That's kind of good news in the fact I can get one bought ASAP. Delivery another problem though!
Do you know if there's any extra gubbins that come off to aid with getting it into place?
The guard looks like its welded to the chassis and there's a tubular surround that's making it a tight fit.....
Thanks again!

 

The intercooler frame bolts on/off the front panel. It is much easier to remove/Refit the intercooler once it's secured in the frame.

 

You need a new intercooler the orange seal blown out indicates it is kaput

 

Champion, that seals the deal! I'm up north so hoping Advanced Radiators is open for a few hrs in the morning...

 

That sounds like a great plan.

 

Boxing day update
Managed to get (but probably paid over the odds-on!) an intercooler from ECP (NISSENS Type) on Xmas eve and got the car back together and hour ago after about 3hrs, so thanks for the advice given on here!
Not the worst job I've had to do on a car, the most frustrating part was trying to remember where the different types of trim clips, self tappers, and bolts all come from! Was a tad worried about the bottom pipe gasket but it all seems OK so far..
Car is road tested and all sounds good, no noise from exhaust systems or rattles from trim etc, just need to find my Bluetooth plug to turn off the EML now and hope for the best!
Thanks again to those who replied and have a good break! (For those lucky enough anyway!)
