Question about Cars & Trucks
Called engineer who said it was a tank problem, he fitted a temporary pipe which is coming out of the top of the tank now not at the bottom. The pipe has a little round device before it goes through the wall to the boiler,this has a button on it. There is no oil coming through near the boiler when I tried to bleed it, I have also undone the small nut on the left hand side of the boiler to let any air out (engineers instructions over phone). There is oil coming out of the pipe OK before the small device mentioned earlier, but not a lot when it is put back on, is this right or is this the problem why the boiler won't start. Engineer can't get to us for a few days and l am reluctant to get him back it's costing me too much money, this is the third time he's been! Hoping someone can help me. many thanks.
Check filter is not restricting flow due to clogging an check oil nozzel this might be worn. also check majic eye is not clogged wipe clean when did you last service

Did you have this problem before you replaced the M/C? Inspect your brake system for leaks, especially the rubber hoses. Make sure all fittings are tight. Sometimes the caliper's seal around the piston will allow air to **** in, but won't leak fluid. Many cars from the 80's onward had pistons made out of plastic which causes a sticking and leaking problem. Many times rebuilt, loaded with pads, calipers cost just a little more than what a reseal kit costs. They have to be cutting corners somewhere.
If your vehicle has ABS, sometimes you have to hook a scanner up to bleed the brakes correctly. If you don't have ABS, you probably have a proportioning valve and these can cause trouble, especially on a high mileage vehicle.

Sorry this is not a solution. Just to say I own a 1997 318tds which only starts on the button if the tank is at least half full. This was looked at professionally shortly after i bought the car 3 years ago.( I did wonder why it was sold to me with such a full tank). I was told it would need the fuel tank replacing. Bearing in mind the value of the car & the fact the owner is now too geriatric to do major repairs, I just make sure it is always half-full, and live with it.. This could be your problem. BMWs chap said it was logged on their system as a known but unusual fault.

The water (coolant) in the expansion tank will rise and fall with the engine temperature. What the expansion tank does is collect and return coolant to and from the engine. When the engine warms up the coolant gets hot, builds up pressure and opens up the radiator cap. The coolant then goes into the expansion tank. Now when the engine cools down the pressure drops in the cooling system and the pressure drop (vacuum) pulls the coolant back into the engine via the radiator cap. The radiator cap allows the cooling system to build up pressure and by doing so increases the boiling point of the coolant, but when that pressure exceeds the caps rating the cap opens and the coolant goes to the expansion valve. The cap has another part to it that when the engine cools down and a partial vacuum is created in the cooling system a "valve" in the radiator cap opens and allows the coolant to be drawn back into the engine. I would look at your radiator cap to see if any gunk or build up is on it, and check the rubber gaskets for cracks. It's easiest just to replace the cap because they are inexpensive and easy to replace (2-10 dollars). The expansion tank should have two hoses on it. The one on the bottom comes from the radiator and the one on the top (possibly part of filler cap) runs down and is open to the ground. That way if it is overfilled or becomes overfilled it will slowly leak onto the ground. When and if you change your radiator cap, make sure the engine is cooled down, remove cap and start engine and turn heater to full blast, full heat. Leave the cap off and let it run until engine warmed up. This should burp out any air pockets that may have happened when coolant was changed. Also top off the coolant in the radiator while it is running. Hope this helps and good luck
