I know it’s a long shot, but before spending the money on the pump, I would try to verify that the pump gets 12v from the relay. Don’t assume because someone might had sharpened their teeth on the cable during hibernation, and the damaged wire broke up during the drive.

The symptoms you are describing are very similar to what I noticed when I started having issues with what was ultimately my SMG pump motor. Check my thread out:

http://www.m3forum.net/m3forum/showt...ighlight=p1717

The definitive answer is check the pump motor with an oscilloscope.

Also, I bought my pump motor from SMG Society. A bit cheaper (~$350) than Burkhart if you want to go that route and DIY.

Fair enough. Appreciate the input.

So I visited my Indy shop this morning and even though he's very capable, he's advised that he hasn't had very much experience with the SMG unit itself.

I told him I'd gather as much information as possible and email it his way. Tried to start it again this morning and nothing...no pump prime noise...nothing. 40amp fuse still good.

Replacing the motor is not hard or time consuming, but you need a good set of jack stands or a lift to do this. And some sort of software to bleed/re-adapt.

Is this the kit...funny enough someone on local Craig's is selling one:

https://vancouver.craigslist.org/nvn...848898165.html
The pressure accumulator test can be done on a hand held bwm specific scan tool like the foxwell NT510 ($170 amazon) or the schwaben scanner (identical to foxwell NT510, just different name)

I can give you a DIY to do the accumulator test if you buy the foxwell scanner. Or you can search the forums i believe someone posted a DIY of how to bled the smg pump with the schwaben scanner.

The burkhart kit https://burkhart-engineering.com/54160en

I purchased back then was $450 not $1200. The kit from the burhart website is only $500-$600. The kit comes with a new temp sensor, electric motor, high performance grease, thicker fluid.

There is a USA re-seller named bluntech that sells burkhart products in USA.
https://www.blunttech.com/products/13219506

There are 2 ways to install the pump motor. I did both ways. You can do it on jack stands with driver wheel removed. There is several videos on youtube showing how.



The other way which I recommend is to remove the intake manifold plenum and then remove the entire pump so you can change the parts on a bench. This method however requires you to bleed the system of air since you will be opening the hydraulic lines. This is where your mechanic autoenginuity, gt1, DIS, or whatever program they use to bled the smg pump. I used my foxwell scanner to do this bleeding processes. I also did the smg transmission adaptation, clutch curve reset, clutch bite point calibration, after the bleed on this same scanner.

You can do it yourself or have your mechanic do it. I can write down the DIY tutorial step by step for you or for your mechanic if you need more help.

Wow! That is a absolutely terrific! Now you got me thinking...he's backed up and won't be able to work on the car for a week or so.

This foxwell scanner will allow me to do all that? Bleed, pressure test etc? I have a tool box with most tools...is there anything specific I would need for the job? If it isn't the accumulator, can I also replace the entire pump via that tool?

I'm a confident tackler, but this may get a little to "heavy" and I may want to leave it to the shop to handle. Either way, if you have time, that DIY would sure be handy...not just to me, but everyone else who encounters this problem.

Much appreciated,

+1 on the DIY. That would be most helpful as I just purchased one of those Schwaben scanners and planing on doing a relocation in the near future. Would love to learn how to bleed, accumulator test, do adaptations etc...

With all this being said, how can we be sure it's in fact the motor and not the pump itself?
