I would think it just a different design, the fuel goes in and out at the top and bottom so whether the actual filter medium is exposed doesn't really matter. I have run 2.1s in XMs for many years but I don't recognise either of those filters so if it works I wouldn't worry about it.

I'm not familiar with that particular radio but most of the older ones were lit with special bulbs which were not at all easy to change unless you were handy with a soldering iron and a microscope, later ones have LEDs. Is it a stand alone radio or is it integrated with the dashboard?

Peter

I would agree, that sounds about right for a suburban/rural area, in cities the labour charge can be up to £100.00 per hour. When you see how much some people pay to have their cars repaired - its more than I pay for a car.

Peter

If for some reason your tracking is out it could have that effect as could excessive tyre pressures.

Peter

A lot more friendly than my C5.

I think you stand a fair chance or that being the problem. I originally changed the pump on mine which cured it but when I later used the regulator off the pump It brought back the hot starting problem so it was obviously the regulator. Hope you are successful.

Hi Graham

Welcome to the forum, I have not been on here very long myself but there are some very knowledgeable and friendly people on here so hopefully you will find what you need.

Peter

I had this problem on a C5 with the 110 engine, it turned out to be the fuel pressure regulator on the HP pump or rather he filter on it, but as its almost impossible to clean the filter a new regulator would probably be the way. They are quite easy to fit, held on to the pump with two torx or allen...

Has this only occurred since the pump was replaced? If so it could be that the level sensor arm is bent, I have had problems with mine since I took the pump out only mine ran out about 5 miles after the light came on!

Peter

Ah right, sounds as though you have an alternator problem then.

That sounds to be within the acceptable range if its load dependent, if there was a fault the voltage would vary with a constant load.

Peter

You could try squirting some aerosol freezer on various chips, that should change it instantly if you have found the right one. That's what we did when I repaired TVs for a living.

Peter

If I were you I would stick with the 14" wheels as the high profile tyres give a better ride but if you want to drive fast by all means fit the larger ones. I prefer comfort to speed but then I'm old.

Peter

You really need the proper PSA diagnostic gear. If you go on to the French Car Forum somewhere there is a list of members with it, see if you can find one near you, assuming you are in the UK, they are a pretty helpful bunch.

Peter

Oh dear. I suspected the pump with mine because if it wears it may not develop enough pressure when the fuel is hot and its viscosity is lower, happens to BMW IDI pumps. If you can get the fuel pressure read both when cold and hot it should give you a clue, can't remember if you have access to a Lex...
