All the symptoms you describe suggest the engine is getting hot to the point it’s boiling, but the gauge should be indicating it’s hot by moving to the hot end of the scale. That’s if it’s working. Make sure the coolant is topped up, and check the electric fan to make sure it is working. I would run the engine at idle with the automatic transmission in drive for a period of 10 minutes and watch the temperature gauge. If it does check to see if the electric cooling fan is running, it it’s not running switch on the air-conditioning and see if it runs then. If it does there could be a problem with the fan sensor.

Were you told why the first engine failed? It’s most unusual for an engine to fail at such low kilometres, and to have it happen again is unbelievable. If the engine has failed again and needs to be replaced Citroen should do it under warranty, which should still be current. If they don’t then go to the ACCC for help, or take your claim to VCAT.

It has a chain.

Yes, it is important to change the coolant, particularly with a BMW with its alloy head. When you do it it’s vital you use the correct coolant as specified in the owner’s manual. Older BMWs, particularly the 3-Series, can be troublesome with high mileage. There are a number of plastic fittings used in the cooling system, including the radiator, and they are known trouble spots. The power steering can also give trouble, the suspension bushes often need replacing, and there are many others. Only buy one if it’s a low mileage car with a known history and a full service record, and only if you’ve got deep pockets.

Don’t mess about fit another EGR valve.

You could visually check the transfer case and CV joints, but I doubt you’ll see anything that might tell there’s a problem with them. It could also be a diff. Get it to a specialist mechanic and have them check it for you.
