Eh?

Yes, but the battery dead symptoms are completely different than the fuel pump control unit. When the small controller is burned out, happens that your starter (electric motor) is running but the engine does not start. It is also possible to have situation where the engine start for 2-3 seconds than stops (happened to me - considering I have burned several of that electronics).

So problem determination is not hard here.

in any case, keep in mind that I have completely removed the electronic module - do not remember if 2 or 3 years ago.
And have no problems with my bike, about 30 000 km done since that.

I saw that pert number of the VDO fuel pump is the same as the previous model GS where such electronic was not included in the technical design of the bike. And VDO fuel pump failore was not common issue.
usually after 120 000 km the pump dies.

that electronic module has been designed to reduce the fuel pump work load. Good idea, but not really needed considering the reliability of the VDO pump.

My suggestion is to have a permanent bypass of that module. If your bike has more than 100 000 and you plan a trip, take additional VDO pump. Pump cost is not much higher than the weak module..

cheers

The module is less than $150. The pump more than $400. Do you have an alternate source for a cheaper pump?

Hello Jim,
below is what I found today.
Actually, last time (3 yrs ago) when I compared prices
I had 122 euro the electronic
and 220 euro the fuel pump.

What I see now, the electronic cost is lower.

In any case, comparing the duration against cost of the parts it is much cheaper and reliable to stop replacing the electronic module.
For me that part lasts in medium 17 000 km. The pump should last at least 6 times longer.
so it comes cheaper.

02 16147680379 FUEL PUMP 0.75 1 $306.54

06 16147720776 FUEL PUMP, ELECTRONIC 0.14 1 $131.59

I think if we start searching , might find lower price.

Other references on electronic module:

another thing to consider is to keep your fuel tank almost full rather than almost empty. The fuel pump is using the carburant to cool itself too.

so if carburant level is too low the pump is not cooling well and suffer.

Mine left me sitting last week-end, 09 adv. A guy brought over the by-pass, but I had no idea about all of this. I told him the connectors were wrong, I was looking at the top of the controller, I didnt know about taking it off and getting to the plug below. If I had known..............oh well, I just ordered the bypass..............thanks to all for the valuable information.

COPY and PRINT and take with you in your tools:

Fuel Pump Controller BYPASS Installation Instructions

1. Remove the left side gas tank cover.

2. Remove the black fuel pump cover.

3. With a small flat screw driver...pry open the retaining clip and remove the power to the fuel pump controller (
4. With a torx socket (size T-20) remove the screws that are holding the fuel pump controller to the top of the fuel pump.

5. On the rear screw...I found it easier to use a torx T-20 screw driver.

6. With a small screw driver...pry up the fuel pump controller. Look inside and you'll see the BLUE connector.

7. Use your screwdriver to squeeze the tabs on the blue connector to make it easier to remove.

8. Now...take your fuel bypass pump cable and align that connector to the top of the fuel pump connector...and connect it.

9. Insert the Powerlet connector into your accessory socket.

10. Now...start the bike.
11. Tuck the cable under the side covers...so they're out of the way.
12. You're back on the road.
