SOURCE: 2000 bmw 540 dashboard temperature gauge goes to

When a gauge goes bad, you have to decide if it is the sending unit or the gauge itself. If you unplug and short the wire to the sending unit, the gauge should go to max (one way or the other), and the opposite when the wire is not connected to anything. If that works, then it is probably the sending unit. If that does not work, it is probably the gauge itself.

Testimonial: "that works thanks"

SOURCE: poor starting problem bmw 318 ti

WARNING! Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when you are near the battery or engine. A battery is filled with explosive gasses that can ignite when extreme heat or a spark is present. A battery could have residual acid on the outside casing so use caution when handling a battery and the surrounding area. Use baking soda to neutralize any suspected acid residue before work begins.

You can check the car battery using a multimeter or voltmeter an electronic one is preferred , connect the black wire to the negative side (-) and the red to positive , WARNING :DO NOT CROSS THE RED AND BLACK WIRES OR SHORT CIRCUIT THE LEADS OF THE BATTERY OR MULTIMETER YOU CAN GET SERIOUSLY HURT!!!!! you should also get a spare watering can and fill it with water ,  (dont reuse for other purposes for safety) and remove those little tabs (usually around 4 or more) and fill it up very little in each tab/cap make sure you DONT fill it to the top. The good condition of a battery is 12.5 and 12.8 volts on the multmeter and when the car is started it
(not driven just started) should around 14V which shows that your alternater (acts as battery charger when driving) is working properly.

Your oil is a little low, and the timing may be off a bit but if it smooths out after warm it is probably ljust
low oil.

SOURCE: bmw 325tds diesel flowing back to tank when parked

usual problem ,valves in injector worn for the fuel pump.easy quick fix this one ,fit a non return valve in the inlet pipe,check flow direction on valve when fitting and evan better as well is another in the bleed off return pipe .valves available from a motor factor or a specialist garage like bosch or lucas ,cut pipe and fit the valve with a piece of rubber pipe to connect the valve in line.or listen to the people who want to milk the golden cow and have the whole injector pump overhauled .

I just bought a 1986 F250 with a 6.9 Diesel in it. In the morning or when it is cold in general it has trouble starting. I am pretty sure this is a glow plug issue. I intend to replace the glow plugs, glow...

Hi,
I would recommend disconnecting your glow plug relay if you are going to use starting fluid.
With starting fluid in the engine and the glow plugs turn on it may explode the fluid and do head damage. Starting fluid and any kind of ignition source ( hot glow plug ) is like a bomb.

1996 318 tds diesel hard to start in mornings returning diesel

Disels are simple, if they have fuel and compression at the right time and in the right quantities they will run fine. You might just have a blocked filter. If the mileage is moderate your injectors or pump might be the problem and the symptoms might have started quite quickly. If the mileage is high, it could be a worn engine in which case it would have got worse over a period of time and you might be using oil. Have a diesel specialist look at the injectors first, then the pump and the engine last unless he can see something obvious.

I have abmw 3 series 1996 parked it last night perfectly ok this morning it wont start the engine turns over very quick as normal could it be because its damp and cold outside what do you suggest?

I would replace Distributor Cap & Rotor; and especially all Ignition Wires (aka: spark plug wires) When it is damp outside, old and possibly cracked wires is the leading cause of engines not starting due to wires arcing (throwing sparks to other parts of the engine) and causes no spark where it is really needed and that is at your spark plugs so the engine will start.

Ford 2002 f250 7.3 diesel won't start on cold mornings just replaced the cold start relay and still won't start...what else could it be?

It probably is your glow plugs which are controlled by the cold start relay. They burn out over time. This is normal. Haynes Diesel Engine Repair Manual, part 10330, will walk you through the diagnosis and replacement easily. It's about $20. Hope this helps.
