My E280 has started to cut out, no error messages etc just cuts out. If I leave it for 20-30 minutes it works again, for a mile or so.

Taken it to a garage and it's showing cam and crankshaft sensor faults (the codes were cleared and checked again after failing). But they have the car running in the workshop and it's been running fine for an hour or so with no codes coming up. Nor can they see the oil leak. They are a bit stumped at the moment.

The car has been leaking a lot of oil recently and was due to go in to be fixed the day after it started cutting out.

Any ideas? Could it be the oil leak causing something?

Its a 2006 car with 166k so not really worth chucking money if you know what I mean.
 
Sounds like the infamous Crankshaft sensor is failing. It will get worse and eventually refuse to start .
Symptoms are cutting out when hot, engine cools down and it restarts.
Its around a £200 job at a Mercedes specialist to supply and change the sensor.

I remember your battle with one buddy ;) .

Did you have one do something like this? Do you reckon it would need to be driven, as it hasn't failed on them whilst ticking over in the shop (nor seemingly has the oil leaked)

Does this cause the camshaft fault as well?

I presume it's got nothing to do with the oil leak?
 
Strike that, sounds like it could be a cause of an oil leak.

What can be done if oil gets into the wiring?

Would you get the same symptoms from a bad camshaft sensor/magnet position sensor?

I ask as isn't the crankshaft sensor at the back of the engine? To me the oil leaks, very much at front of the engine, and the camshaft code seems possiblly related.

Will a camshaft sensor fault throw a crankshaft sensor fault and vice versa?

It was the camshaft sensor
 
Camshaft and not crankshaft??
How much was the repair?
I apologize for any confusion. The repair cost for a camshaft replacement or repair will still depend on various factors, including the vehicle make and model, labor costs, and whether it's a full replacement or a repair. It's important to consult with a mechanic or a repair shop to get an accurate estimate for your specific situation as costs can vary widely.

I'm sorry for any misunderstanding, but I don't have access to specific repair cost information as it can vary greatly depending on various factors, including the type of vehicle, the extent of the damage, and the labor rates at the repair shop. To get an accurate estimate for your specific repair, it's best to contact a local mechanic or auto repair shop and provide them with the details of your vehicle and the repair needed. They can then give you a cost estimate based on your particular circumstances.
