After 2 years where the needle on the temperature gauge hasn't moved, I started to have a problem with overheating yesterday (Surf 3.0 Diesel automatic). The first thing I noticed was that the oil pressure had dropped quite low while stuck in traffic. Then 10 or 15 minutes later the temperature starting rising as I was about to enter a car park. I realised later that it was doing this every time I came off the flat and had a few extra revs on. I checked the oil and water. Both could do with topping up but neither were below the minimum marker. I topped up and continued my journey and things were fine while in traffic and/or on the flat, but I started to overheat again when needing extra revs. I'm not losing any water so I'm a bit stumped as to why. I'm wondering whether it's connected to the 'O/D Off' light flashing a couple of times recently (although it wasn't doing this yesterday). Does this flashing light indicate an auto-transmission problem and if so can this cause overheating?
