Question 240D won't turn off

I drove home from work and immediately noticed that the brakes were horrible, they were not working well at all. It was very hard to press the brake pedal down. When I got home my 240D stick shift would not shut off even when I turned the key and removed it from the ignition. What is going on? How can I fix this? Thanks.

You have a vacuum leak.

First off, you can use the emergency shut off on top of the engine to kill the fuel supply. If you don't see it refer to your owners manual.

Driving any car with disk brakes and no vaccum assist is very scary and worse, can be dangerous. I would suggest not driving the vehicle until you solve this problem.

Next, you need to determine why you are not getting vacuum to both your brake booster and your fuel injection pump. I would guess that you might have a bad vacuum pump. It can see it by looking at the engine (radiator to your stomach) it will be on the right side (left side of the engine). You will see a white tube about 1/2 inch, if I recall correctly, running from the pump to your brake booster.

If you do a search in the Diesel section using key words such as vaccum and brakes, you should turn up quite a few postings.

Keep us posted,

This picture will show you the line from the vacuum pump to the booster. (I modified a recent photo posted on this site)

You are welcome. I noticed that your last post had a different model # than the title. It shoud be similiar between a 220D and a 240D, but not exactly the same.

Keep us posted,

Tip on finding shut-off lever...

This happened to me, too.

My mechanic told me what to do over the phone to shut the engine off. Open hood, stand with toes against driver's side front tire, and look down at the top of the engine. You should clearly see a red lever marked STOP about midway back atop the engine. Push the lever and the engine will stop.
