Check that the EGR vacuum solenoid is working. Remove the vacuum line to the EGR and there should be no vacuum in that line with the engine at idle.

SOURCE: Do you have instructions on removing and replacing

REMOVING
Removing the master cylinder is really simple, only requiring a few steps. Keep in mind that brake fluid will eat the paint of the car. So use a plastic or vinyl type fender cover to protect the vehicle's paint. Brake fluid is water soluble so if you should get some on the paint, wash it off with plenty of water as quickly as possible.

  1. Using a siphon, an old turkey baster works great, empty the master cylinder reservoir and dispose of the old brake fluid in the proper manner.
  2. Disconnect the wire connector for the brake fluid level and/or brake pressure-warning switch, if your vehicle is so equipped.
  3. Disconnect the brake lines from the master cylinder with a line wrench. A line wrench is specially designed to remove and install hydraluic fittings without rounding them off.
  4. Remove the master cylinder mounting nuts, then the master cylinder.
  5. On non-power brake vehicles, disconnect the master cylinder linkage from the brake pedal underneath the dash.
  6. On models with separate fluid reservoirs, remove the reservoir.
REPLACING
Before installing the new master cylinder on the vehicle, it must first be bled using a specialized bleeder kit. The master-cylinder bleeder kit comes with tubing, clips and multiple adapters. Most new or rebuilt master cylinders come with a bleeder kit for that particular master cylinder.
  1. Begin by removing the cap.
  2. Follow the directions that come with the kit to select the suitable adapters, and then connect the adapters and tubes to the ports on the cylinder. The other ends of the tube extend down into the master cylinder, and are held in place by a plastic clip. Figure 2.
  3. With the bleeder kit installed, fill the master cylinder about halfway with new brake fluid. Use a large screwdriver to depress the valve assembly inside the master cylinder. If you do not have a vise you can mount the master cylinder on the vacuum brake booster and bleed the master cylinder.
  4. Small bubbles will appear in the fluid. Continue working the valve assembly until no more bubbles appear. This indicates that the cylinder has been thoroughly bled.Reverse the removal procedure to install the master cylinder, noting the following Refer to your service manual for any Master Cylinder Push Rod Adjustment procedures if your vehicle requires it.Bleed brakes as described under Brake Bleeding.Operate the brakes several times and check for external hydraulic leaks.This is fairly straightforward job. Replacing a master cylinder should take you about 1 to 2 hours, depending on the make and model of car. If you are rebuilding the master cylinder, add about another hour or so.

SOURCE: i need to know how to install a egr valve in a 05

Once you are able to identify the EGR, you simply unbolt the valve and ant other obstaructing part. Clean its surface of carbon. Repalce the gasket if worn. Any sticky bolt/nut that you encounter could be removed by spraying some WD-40 around them. Also disconnect the negative wire of the battery first. Diesel do run hot, so get ready for some hard bolts to loosen.

Should be on the right side of the engine by the starter.Has a 1 wire connector.It does not go into the cooling system so you can just take it out without draining the coolant.Hope this helps.Good luck.

When you shut off the motor, see if fuel is dripping from the injectors. It sounds like one might be leaking.

Engine won't idle,


ok code 32 is the EGR (exhaust gas recirculation) this does not mean that the EGR valve is bad right off, check it and see if it is stuck in the open position, remove the vacuum line see if it moves, it should not. It is supposed to open at highway speed to recirculate exhaust gases and burn them, if the valve is stuck open the engine will not idle because it upsets the air mixture too much, if you remove the valve and see its open, then replace it.
