25mls into a quick run and the dashboard decided to imitate a Christmas tree.lol
Got home put the Delphi scanner on it and this was the result.

according to most on the net this almost always leads to ABS pump/module replacement. Also says BMW can supply new part at over a £1000 and fitting would push price to in the region of double. After cancelling faults the scanner wouldn’t read any part of the braking system.

So jacked the drvs side up removed wheel and wheel arch liner to get better access to the ABS pump/module. Numbered the 6lines up took pic and made drawing of unit with pipes attached. Found half a wooden broom handle and propped brake peddle (pressure on) against drvs seat, easy with elect seats to get the right pressure on the brake peddle. This I was told (by @t-tony ) would push the survo piston past the replenish port holding it there( till repaired one fitted) so as to isolate the reservour thus no need to lose all the very new fluid. Less messy, only a few drips from the pipes getting unit off.

Unit with cushioned bracket still attached removed through the wheel-well.

unit all ready to get boxed up sent away.


Car was parked in everyone’s way outside my lock up garage but was drivable back into garage (as long as the brake peddle prop stays in position) using handbrake.
Contacted ECU Repairs and they sent me DHL post label and pickup date. So it’s off tomorrow to be tested and repaired if poss. If no faults found there’s a charge for testing and post, if repairable £259-ish all in. At 140,000mls this unit if original has done its job. Now that’s what I call very reasonable.
Will let you all know what the outcome is.

RHA,ROY.

Got it back from ECU testing today and it's raining, same forecast for all day tomorrow so looks like it'll be Sat to fit it back into the coupe.

Checked car/brake reservoir catch cloth and still hasn't lost a drop.
Half broom stick handle (tip from Tony) working a treat.

Price so far could be a saving of something in the region of £1500-2000 if it had gone to main dealer, Indy something like
£800-1000 est, using rebuilt part. Now for the hard part, bleeding the system. Been looking through what help my Delphi scanner can be and I'll be able to open all twelve valves in abs pump one at a time plus switch pump on/off when required after fitting and before/during bleeding, fingers crossed.

Roll on a dry Sat.

RHA,Roy.

Repairs conducive to the faults of 5DF0,5DF1 and that's from their office. Couldn't speak to the engineer who revamped mine. By looking at their ad they say that the pumps/modules are completely overhauled and looking at mine they've defo taken it apart. To me that means they've checked more/all parts for ongoing longevity as how can they give a lifetime guarantee. If different faults come up whilst still in my possession I wouldn't hesitate to send it back even in 4/5 years time. They have good revues and this is the same company that repaired my Z3 pump module back in 2010 but they were only a small company and I spoke to the owner himself then. They keep you up dated as the item goes through their system.

Sounds good Roy. Fingers crossed for a Saturday fit. Worth knowing about the repair company.

When it comes down to doing your own maintenance Dawn owning BMW albeit a older one, there’s a bigger urge to save some pennies if your prepared to use perfectly good used/re-manufactured or non OEM parts. Of course a little mechanical knowledge when messing with brakes/steering and suspension is needed and when available some guidance,
that’s one of the huge advantages of being a member of the best club on the planet.
A big thank you to all the founders/Shed crews and experts. We really dont know how lucky we are. ( Well I do anyway )

(Just a little grovel now and again doesn’t hurt, surely???? =)))

It’s Friday dry and not raining but I’ve already promised the boss I’d go into the loft to retrieve Xmas decs and spend a day with her putting them up, so there goes the coupe on the back burner yet again, but we all know a promise is a promise and points mean coupe time later. ( WHAT FLIES????)=)).

Sat came and forgot to put my alarm clock on for 7.30am, so arrived at my lockup a bit later than planned at 10.25am.
The wind was howling and temp was 9deg supposed to be 12. Felt cold but soon warmed up getting the coupe in the air wheels off ready for bleeding brakes.
IMG_1695.JPG

Fitted abs pump/module to bracket and bolted it in position. Then with 11mm bleed spanner fitted five out six unions and as usual being fine thread into alloy pump block number 6 just wouldn't start to thread in properly, now everyone knows what a real ba-----d this could turn out to be if it cross threads. So I unbolted the unit from its mounting and about 1hr later with absolutely raw fingers got it to thread properly. Bolted it all back onto mounting and found I'd lost one of the three bracket bolts, more time wasted looking for it. Never found it but did have same size thread bolt too long so used a nut to space it out. It's under pump and not visible when the wheel arch liner is back on.

Called a mate to help bleed system even though have vacuum self bleed system. We put the Delphi scanner on and all the lights were still on.

Faults wouldn't clear so started bleeding. After first bleed we tried to clear faults and was successful only because I hadn't pushed module connector fully home and locked it in.(would've cleared first time if I had) Peddle was feeling good but still decided to bleed again to make sure we got all the air out. The vacuum bleeder although worked was taking too long so we reverted to good old way. wheels back on dropped the car and tried brakes on access road all fine. Took car to what we call our "mile straight" and done eight emergency stops all good with fronts trying to lock up but abs not allowing them too. Peddle seems just a fraction less sensitive at top of travel so might bleed again.
No more warning lights or faults on yet another scan. Used just over 1/2Ltr dot 4 brake fluid. Missed lunch but was so keen to get it done couldn't stop.

Conclusion; Didn't relish this repair but with the help of my mate I think it's perfectly do able at home on your drive if the weather holds. And just look at what BMW agents would have charged, the indies are not cheap even with the re-manufactured abs pump. Just one job left now and that's to quieten the beast down a bit my poor ears have had enough @Lee new year new sound.lol

RHA,Roy.

Glad you got it done my mate.:thumbsup:

Tony.
Thanks Tony, great tip you gave me, all my recent new fluid change didn’t leak more than a couple of drips, obviously it got thrown away but better than having it leaking out for nearly a week waiting for pump to come back. Did drive car in out of garage and knocked b/handle twice. Clumsy also comes with age. Had a great sleep last night as was knackered. Think I’ll bleed one more time just to put my mind at rest but that’s another day because putting outside lights up today, another promise made. Ladders out fingers crossed. :facepalm:
