I have a 2005 Bentley Continental GT that recently had a dead battery. After a jump start the vehicle had the following two symptoms:

At approximately 10 MPH
1. Code 00301 - ABS Return Flow Pump
2. Code 01316 - ABS Control Module
3. The left dash lamp for ABS is illuminated
4. The center dash lamp stating: "Brake Fault Stop Vehicle"

So basically I have never seen an ABS or Parking Brake error until post jump start.

Here is what I have done so far:
1. Replaced both batteries
2. Checked ABS fuses in Trunk and Steering Column
3. Reset codes with ross-tech VCDS HEX-V2
a. The codes and light clear and stay cleared until the vehicle reaches approximately 10 MPH
4. I did re-center the steering wheel via the ross-tech procedure after the battery replacement. Its at 0 deg
5. I removed and reconnected the ABS connector under the hood. (no science there)

Here is what I see as my options:
1. Ask for expert help here
2.a Order a used ABS module. ~$500 ebay =>Will likely need to recode with VCDS
OR
2.b Send mine to be repaired for $150 (modulerepairpro)
3. Take to indi shop. I am in Melbourne FL, no idea where to go. I have been doing everything myself up until now.
4. Take it to the Bentley dealer in Orlando or West Palm

Hi and welcome.

Have you been here?
http://wiki.ross-tech.com/wiki/index.php/00301

It seems the return flow pump is more likely the problem than the ABS module.

Option 1 is what I would take, at least for a few days, and today is Sunday, meaning some of the regulars here aren't around.

There may be an output test in the ABS module that will run the pump, so you could check if it actually functions.

I know in the MK60 units, they can clog up, because they are hardly ever used and the brushes create a carbon mess in there.

That is a great idea. Anyone know the procedure to do this from VCDS? Or another way?

I replaced the ABS controller, just the black part. It was very tight and required removing the power steering Reservoir and the driver side soft intake hose. It took 2 hours.

Then I recoded it per the Bentley ABS instructions here. Another 30 min.

It did fix the issue.

Summary; Jumpstarting my Bentley blew up the ABS controller. replacing it with a used one from eBay fixed the issue but it did have to be recoded
