Help With A Few Queries Please.

[stevej60]

Hi,folks a little bit of help and advice please,I have a 2003 2.0hdi bought last year with 56000 on the clock,the first owner only

put 26000 until parting with it in late 2012, the rest(now 67000) by the second owner and myself.I am having an oil filter/oil change

next week as it has done 12000 since last done is there anything else I should renew ie fuel or air filter as well?Also when the engine

is at idle the engine runs at just the wrong side of smooth(if that makes sense) at about 8/900 rpm,just touch the pedal and take it up 

to near 1000 rpm  and it is as smooth as silk,is this just a characteristic of the HDI engine,can it be adjusted or should it be left alone?

and lastly the air con has stopped working the light does not come on nor on the right hand button(cabin airflow?) I have checked the

glovebox fuse can,t see a problem any thoughts?thanks in advance,Steve.

In addition to oil and filter change, I always renew the fuel filter, the air filter and the pollen filter at 20000.   If you don't have any record of when these items were changed, I would do them now.    Perhaps on mileage, it's a bit early for a cambelt change, but if it hasn't already been done, it's over the ten year recommendation.

Thanks for that John,I will ask him to change the additional filters.

Aircon: The fan speed controllers aren't the most reliable of items, and if there's no fan running then the aircon will be locked out.

 

If it's basic aircon then there's a resistor pack in the passenger footwell, next to the cabin filter. These burn out, but even if they do the fan should still run on the maximum speed setting.

 

If it's climate control then there's an electronic module to the left of the steering column in the driver's footwell. You'll need to remove a small steering column fuzzy cover to access this (quick and easy). The most common faults on these tend to be dry solder joints or a blown MOSFET. If you have to solder a fix you'll need a powerful iron, and don't use ordinary lead/tin solder as it's not reliable with gold-flashed PCBs - use lead-free (RoHS) solder, or lead/tin/silver solder.

There are companies that fix these modules, and I've seen them new online for about £20 or so.

Thanks for the info,the fan works fine on all settings,it,s going in for service net week so will ask them to check the other items mentioned.

Sorry stevej60, misinterpreted your OP. If the car is going in for a Citroen service then their plug-in diagnostic gear should tell you what's wrong. The aircon does seem to have a number of interlocks, so if a critical item is faulty it disables everything else.

Thanks,it,s just going into a very reliable small garage that used to look after my Picasso,he is going to see what,s up.Popped in to book it in for service

next week as I also  have a light knocking from the front even on a reasonably smooth road identified as a dropped joint front passenger side £12 for

the part so no great worry.
