No there appears to be something amiss with it, so get the dealer to check it again. If that doesn't resolve the issue take it to an independent diesel engine mechanic and have them check it for you.
We haven't had any reports of water leakage on this model, which suggest there isn't a widespread problem. You don't say if the car has been involved in a crash, as sometimes water leaks can be a problem caused by poor panel fitment when a car has been repaired. Other than that check all the seals, doors, windows, air vents etc.
It could be a blown head gasket as your mechanic suggests, but he should be able to test it to determine if it is blown or not. You should also be able to see evidence in the form of a milky substance in the coolant if it is a blown head gasket.
I would guess that by specifying the fuel the mechanic is eliminating fuel as a potential cause, so I would go along with him while he attempts to isolate the cause of the problem. As it doesn't show-up on the diagnostics it's hard to track down, so give the mechanic some space to get to work on it, but keep the pressure up. At the end of it it's likely to be a faulty sensor or maybe a faulty coil pack.
It appears they haven't, but we will check. In the meantime religiously stick to the maintenance schedule and change oil and filters regularly.
It's always a good idea to read the fine print so you know what it and what isn't included in the servicing schedule. I would expect that the brake fluid would be changed as a regular part of the servicing and shouldn't be an extra cost. Doing the power steering fluid is being over-serviced. Draining the transmission oil and replacing it isn't hugely expensive, but changing the oil, which includes draining the torque convertor, is more expensive and amounts pretty much to a full service. It's still worth doing and 100,000 km is probably a suitable point in time to do it. As for your diff noise, you could try asking your dealer people to go for a ride with you to assess it. Changing the diff oil can help quieten the noise.
You should take it back to the people who installed the gas system, as something is amiss with it.
Some early Captivas fitted with the diesel engine may have experienced a condition whereby the camshaft rocker arm bearing could fail. In some instances this rocker arm failure was known to result in damage to the camshaft(s). A revised camshaft rocker arm assembly was released into vehicle/engine production to address this problem. These revised parts were also made available to service to replace any failed parts in the field. The service fix advice if presented with a 'Rocker arm failure', is to replace all the rocker arms with the revised parts.
