Ok first of all ahhhrrrggg f*&#ING piece of French #&%!.

Had the Rallye for less than 300 miles and noticed the coolant was under a lot of pressure.
So i did a full coolant flush and bleed,let it warm up,fan kicks in,bleed again bla bla.
Well its still super pressured and the top radiator hose is rock hard. Lots of pressure even when i check the coolant in the morning.

Temp doesn't go above 90c.heater is hot

Now the car decided to also cut out when approaching junctions. Only happened a handful of times in the last three days.

When i turn the key to start the engine it fires up,then the revs bounce up to around 2k then drop to 900 ish. Recently just dies down and cuts out.

Also there is a hesitation in lower revs up to 2700ish and the car occasionally judder/ attempts to cut out.

Once again I have a driveway queen that I feel paranoid to drive.
Booked it in for a compression test end of the week.. Is my headgasket going?gigantic airlock? Or what's causing me all this grief?

Any help/ suggestions/ tips/ bad News much appreciated..

I thought so. Also there was lot of copper coloured really fine metal in the water when i flush and bled the coolant. What could that be?

I'll take it to a local garage for a compression test later this week and report back.

I have found around t/wells there is some sh#t petrol at the moment so that could be one of your problems , what does the the oil/ filler cap look like any sludge? history of the cambelt / waterpump? and i take it you have bled all three places?

now new booted , boosted and flying again!

I only fill up at total in Crowborough and always have at least half a tank. Receipts for cambelt and waterpump at 79k miles iirc. It's now on 86000. Oil cap is clean and so is the dipstick and radiator cap.
Bled it thoroughly twice,no bubbles at all using a header tank and good quality coolant. Temp doesn't rise above about 85 and only came near 90 once in slow traffic. Fan does work when i ran it hot while bleeding it.
The revs bounce up to 2k for a second when i start it from cold.. what does that indicate?
No smoke or water from exhaust either.
The upper radiator hose was really pressured earlier. Any reputable garages around t wells for a headgasket job?

You are bleeding it correctly, so no issues there.

The revving up to 2k on starting is most likely down to the ICV needing a clean. Whip it out (2 bolts) and give it a spray with WD40 or similar and a wipe with a clean rag then refit. It may well solve your issue.

There shouldn't be any pressure after a while of the engine being switched off.

For example I can run my car for say 50 miles, get out and switch it off. If I come back 4 hours later and take the rad cap off, you could hear a pin drop, there is no sound AT ALL.

Pressure being kept in the system for any longer than 3-4 hours and there is an issue somewhere, pressure being being kept overnight or for a couple of days is pretty much a guaranteed HG failure.

So we were right about your HG failure then??

While you are cleaning ICV disconnect your battery and leave it off for 15-20 mins,then when you reconnect it start the car and switch on headlights onto main beam,heater on flat out and leave it idle like that for a while,it re-sets the ECU

Try unplugging the lambda, and go for a drive.

Doing this will make the ECU run on it's "base map" from the factory which is there or thereabouts correct. If the car runs much better, then the lambda is goosed. However, be aware do not run the car like this for a long while. It will be using slightly more fuel and the excess fuel will not be doing the cylinder bores or catalytic converter (if you have one fitted) any good. You are simply carrying out this operation as a test to diagnose the lambda.

True. It only seems to do the hesitation when warm.I think.. i never boot it when cold anyway so it may well do it then. Does seem to use a lot of fuel.. I'll try unplugging the lamda sensor for a few miles. Cleaning icv didn't seem to have made much difference.
