Ford Problems

Ford's claimed fuel consumption for that model was 11.4 L/100 km overall, which means you should get 550 km or so from a tank of fuel. Regular unleaded was Ford's recommended fuel for your car, that's 91-  octane. They also gave the tick of approval for E10.

Based on your figures it's consuming about 50 percent more LPG than it should. It should be doing around 17-18 L/100 km on LPG, not 24-25. I would have the LPG system serviced, and the spark plugs and plug leads changed.

The problem was solved when the external oil cooler was introduced. It was no longer in contact with the engine coolant, so there was no chance of coolant getting into the auto and causing the damage that was common when the cooler was in the radiator.

We haven't had any specific reports about the diff in the FG, although we had plenty about the diff in earlier models. If you've given it a hard time you might have cooked the oil in the diff, so have it changed.

It can happen at any time, it doesn't have to be at 170,000 km. It happens when the transmission oil cooler, which is in the radiator bottom tank, fails and allows engine coolant to enter the transmission fluid stream. It's common with the BA and BF models, but not the BFII, which had an external transmission fluid cooler to overcome the problem. The only real way of ensuring it doesn't happen is to fit an external transmission cooler and bypass the one in the radiator.

Take it in as requested, even though you had the sensor replaced in 2006. It could be that Ford has an updated part that was developed since 2006 when they originally replaced yours. You don't know what part was used back then, it could simply have been another part of   the sort that fails. You should take advantage of the offer of a new sensor. But at the same time Ford has acknowledged that there is a problem with the sensor, which should put you in the box seat to have the cost of replacing the sensor back in 2006 reimbursed. I would   work through the dealer, and have him make a request of Ford for the money to be paid back.

You've probably got a number of problems. The rattling noise and the vibration could be the exhaust hitting part of the body; the overheating could be a radiator issue.

If it's not getting into the boot directly it would seem to confirm that the boot seal is doing its job. In that case look for openings in the boot lid itself, outside the rubber seal that are exposed to the elements. They should be sealed, so perhaps the sealing is damaged.
