1. Seems to be running a bit hot - whilst the car is moving the temperature gauge remains pretty much the same at 90C but when stationary soon goes up to 100C or slightly hotter. Fan is working OK, problem with thermostat?

2. Fast ticking of accumulator. Replaced accumulator about two years ago, but only made a little difference. I've another new accumulator, so try that and see what happens?

3. This is a new one and started on a very hot day. Changing up from 3rd to 4th (auto box) the engine suddenly revs up, almost if it is slipping. All other operations of the gearbox are smooth. Double check gearbox level and change fluid? Must admit I haven't driven the car since so need to test it again to see if the problem is still there.

Thanks
By way of an update:

1. Seems to be running cooler now with a flushed radiator and new coolant. It did cross my mind but could changing from a plastic to a metal bonnet make a difference?

2. Previous accumulator must have been a dud and I should have done something about it sooner. Poor marks to the garage that fitted it too...

3. Kick down cable had broken. As garage couldn't source a replacement they had to make up one with parts from a bike shop. This leads to the inevitable question does anyone have or know where to source a new cable from please?

As part of a lot of work done to the car I had the rear brakes/disks/bearings replaced. All was well but then the ABS light wouldn't go out. Great that's all I need I've spent more than the car is worth on parts/repairs and now it's an MOT failure... Then took the car out again with my mother in law in the back and all was well again, so let's hope that's the last of it.

Parts from a bike shop is a good way to go before tackling the proper job which is a complete PITA on both sourcing the cable and fitting it!

I could not get a cable from Citroen as no longer available even a computer search of dusty selves across the land so keeping your eyes peeled on Ebay is best answer. No one on the forum was able to help.

Fitting it is another issue because the cable does not attach conveniently to the outside of the box but requires partial dismantling of the valve chest interior to the box and working for some period on your back. Garage time on this task is likely to be expensive even with their advantage of a lift!

Worse than I thought. Now begs the question as to how the garage has done the "repair" as no mention of the box being dismantled...

They will have joined a new piece of Bowden Cable interior to the "tail" which still is attached & enters the gearbox. It is highly likely that the cable broke outside the outer at the top of its run where it runs around the throttle quadrant, as this is exposed to air. This can be fixed temporarily with three bits, 1:a nipple barrel, 2: a short length of Bowden Cable interior and 3: a jointing connector.

I would check out how they fixed it because if the cable had broken lower down then their temporary fix could be more problematic for continued operation.

Ref the metal V plastic bonnet and I have two Athenas with one of each!. There is no real difference EXCEPT the plastic trim piece (a thin flap of black plastic with holes in) just behind the front of the bonet is different. I have not worked out the exposed area, via counting the hle diameters etc and totalling but they are different. You should swap the trim piece too if you can as the metal bonnet has a longer overlap down than the plastic. The plastic should also have two lateral grille parts too, filling the longer space.

Interesting thanks. Mine seems to fit OK, but I do wonder whether I should have salvaged the GTi's old plastic bonnet soundproofing in case that may have made a difference to the cooling.

Yes that was my concern, just what sort of bodge might they have done...

Well the mother in law trick didn't work as the ABS light is now back on again. Many years ago I recall seeing a fault finding guide to the BX's ABS, is anyone aware of anything like that?

That ABS guide is part of the Citroen workshop manuals... The PDF can be downloaded from the archive of an old BX site I linked to in a recent post about autoboxes...

Thanks, the link being: http://web.archive.org/web/200805041458 ... /citroen2/ and specifically for the ABS: http://web.archive.org/web/200502240848 ... es/abs.pdf and possibly a bit too complicated for me... I guess the next step is to find the spare rear sensor I have in the shed and go on from there.

It wouldn't make any difference to the cooling.

Agreed, the sound proofing is not part of the air intake to the radiator. The plastic sheet just behind the bonnet nose and in front of the rad is part of the air flow intake, but I doubt it makes too much difference as the fan is largely a little lower. One type has holes in it, the same as my 1.4 petrol 150C beast had, the other is slightly different.
I'm going to be changing the fan switch on my rad soon anyway as I'm fairly sure it's not working.....
Never had one fail on the 14, but that will be the second on a 1.6, seems a bit odd, but it is not that uncommon even on new cars. Now where is that 11 litre washing up bowl to drain it (cooing mix) all into... :wink:
