Are you loosing engine oil? if so, you may have a oil burning prob from the head. I've seen comlete overhauls done on your model with 60.000km due to your symptoms.

Nice car 17 years ago,..
:Might want to check the maintenance history if it has any. ATF changes for auto boxes, T-belt changes for both pet/die engines.
Powerful chemical cleaners used in cleaning engine bays and under carrages cause problems later on.
for ex , alternators get shorted out as the coil within looses it's insulation.
Good luck.

It's possible you have had a leak in your a/c system by your discription. and the compressor is not working as a result.
Start diagnosys by taking the car to an a/c workshop to do a pressure test to confirm .

As Davy , the car does not have a memory of maintenance.,.
Looking at the illustrious history of failiures, I would getsomething else for your budget.
Good luck.

Congrats on your new purchase,..
Would go on to recommend a full service with trans fluid change and all filters.
get the injectors re-pressureised at a good diesel workshop.
Enjoy disel motoring,..
Any idea of the maintainance history of the car?
if the answer is nothing, start with a trans fluid change with filtter. get your gearbox and engine mounts checked.
Good luck.
