Cuts out while driving along . Not a lot to say, have changed the crank handle sensor.

Ignition module i change lots of those

Replace cam positioner sensor and crank positioner sensor one is failing hard to tell which on the c230 just do both fast and easy

run the fault codes to determine the faulty sensor.

pick-up coil

Try the drive shaft sensor. Had a similar problem and had the drive shaft sensor replaced. It worked.

Hi Pam,
Sound like the mass air flow sensor.
While your car is running ,lift the hood .Follow the hose from the throttle body to the air filter box.There will be a sensor mounted as part of the hose. Tap on the top of the sensor with a screwdriver handle a couple of time, if faulty it will stall the engine out.

Mate i had the same problem just change your ect sensor (electronic coolant temperature sensor on the intake manifold goodluck

Is this a diesel TDI PD ?? If so i had the same problem with one of these TDI engines and traced it to the crank sensor signal implausable. The revs would start increasing with no pressure on the throttle, lots of black smoke and then cut out. The crank sensor wiring was at fault in this case. The ECU didnt know where the crank position was in relation to the camshaft and was guessing when to inject the fuel. Hence the black smoke ! Hope this is of some use.

This is something you can save money on by trying to fix it yourself. You can get a free scan at Autozone or Oreillys. If this does not show anything you need to use the "wiggle" test.

A mechanic would check the battery cables, then grab wires and wiggle them while the engine is running to see if it affects the car. There is a connector on the TPS, a throttle sensor which is behind the Air Filter ductwork. It is attached to the horn shaped metal part. There are plug-ins for cam and crank sensors. Look for green corroded terminals with the engine off and the sensors unplugged.
If no luck under the hood, you may be able to reach wires going to the fuelpump and fuel gauge. It should not take much to simulate road vibration.

What you would need to do after this is take it to a shop where they will hook testing equipment onto your car and drive it hoping to get it to defect at that time. Intermittent faults can take several attempts to find. Good Luck.

just change the crank sensor,You have an inntermitent fault with it,
