In reply to Wilsonrobj:
I have had three berlingos in the family fleet. All the older ones ,03 and 04 , were cheap to buy and run.
There have been a number of forum discussions on here about the engines . Worth a search.
The consensus was the older 1.9 D diesels were bombproof, as was the older 2.0 hdi.The newer ,1.6 hdi are relatively fragile. The advice I got for this engine was to change the oil and filter properly ( through the sump plug ) and always to let the engine tick over for ten seconds to let the turbo cool before switching off.
The old berlingos are galvanised so are not rust buckets like some other makes.Worth checking out if you are getting an older vehicle.
