2003 r1100sa ABS pump failure 2x

2003 r1100sa - ABS failure - pump bad 2x in 4,000 miles. Bike had low mileage from the first replacement at 23K. Now has 27K, although has been 6 years. What the heck is this !! Dealer wants $3500 for a new pump installed. Bike is not worth that to me, after the first pump install I do not want to put that kind of bucks into it. I asked if the dealer would do a by pass of the ABS, was told it would cost even more. Plenty of extras, motor runs strong. Original owner.

ABS lights read out low level in ABS pump. Dealer says fault readouts point to pump failure.

By pass? Part out? sell as is?

Anyone else have this issue?

Thanks for the feedback....

That's bad luck on the pump - no way it should fail that fast. Did you do regular flushes over the 6 years?

If you still like the bike, I'd do an ABSectomy. I've done two ('04s) and they're pretty easy - lot's of DIY help on the forum. Total cost would be for a set of new lines from Galfer or Spiegler for a couple hundred dollars.

Remove it, there's great brakes under all that mush. Search the threads for ABS removal on your year bike as you'll have to leave the computer to run your brake light & speedometer. Fortunately I have A '99 & it is much simpler, only need to remove it & run lines from masters to wheel cylinders. It will also take a fair amount of weight away up high, I noticed it immediately on the first ride as the bike turned in quicker.

Will have to search further. Dealer is telling me the inspection will not pass if removed as the bike came with iABS. I also have an iABS failure on my 2002 r1150rt, same iABS module. It is original and fluid was flushed two years ago. Both bikes, both have iABS pumps according to dealership. I did not do regular flushes on the r1100s replacement pump as ofter as I should have. I have read that the iABS units are a little more difficult then others to replace. You know anyone in the Philly area ?

I would check before I believe the dealer about inspection. ABS was never required on bikes.

I am sure that not ALL inspection locations would know, or even notice. Not a problem, was just mentioning they wanted nothing to do with removing my ABS unit. Asked directly. What is killing me is I have two bikes, both with ABS failure. This second one is unacceptable, would like to remove I guess.

Tom Cutter . Rubber Chicken Racing. 25 mi. North of Philly. on I-95. One of the best Independent BMW Techs around. I would check with him. Maybe your I-ABS pump is still good. You mentioned somewhere it was low on fluid. They need regular service intervals. Also updated braided brake lines are a good idea. The I-ABS brake flush, pump included is quite a process for some. Also some BMW Dealerships. Don't want to mess with old bikes or are limited to servicing current models.

Bypassing the iabs is not expensive. I did it on a k12rs with iabs (absIII) and it was easy. Not sure it's required to pass inspection. Although abs isn't required for all motorcycles it is standard equipment on that bike. Remember that the abs lights will continue to flash so you might have to do something about that for the inspection.

I remedied that by pulling the bulb

Sounds good. Remember if you sell the bike put the bulb back in and disclose the non functional abs in the buy/sell. The attorneys here may say that alone won't eliminate one's liability. Dunno.

Agreed - I'd never sell without full disclosure.

I canít help much as iíve managed to avoid ABS like the plagued(until my latest 2) I know their are fans out there but iím Not one of the them.

I waited nearly 2 years trying to buy a K1200r Sport without it and finally had to give in and put up with it sure enough the ABS unit went belly but later versions!! well later than 07 have come on by some margin.

When the one on my K stopped working guy at the shops says ĎBeen down a pot hole?) and sure enough I had but iím Reliably informed later stuff is much better so iíd Be looking for a modern day rebuild its come on some in the last 15 years.

If you have not already done so, R&R the factory brake lines with SS, either Galfer of Spiegler. Not uncommon for stock lines to rupture internally, causing what appears to be an ABS failure.
Dealers can't/won't remove an ABS system due to liability issues. Not such a tough thing to do on your own, if it comes to that.

Ditto. I performed the "surgery" on my '02 many years ago and am very pleased for a number of reasons. As tic suggests, you should remove the ABS indicator bulb (and the small blue relay in the right side relay/fuse pod) and all will work just fine.

If your energetic and can weld aluminum, you can take advantage of the additional space the ABS pump occupied and enlarge the stock aluminum tank at the same time. I fabbed a tank "extension" and my new capacity is about 6.3 gallons. I posted the process but I fear the photos are no longer visible as I have not renewed my Photobucket account...which used to be free! Is the "cloud" a free solution when I get a new smart phone? (sorry for the off-topic question. A PM would be greatly appreciated.)
