SAI Pump, after market Replacements

[flat6]

Hi All

Just had the SAI pump fail on my mrs Polo GTI, just wondering if an after market $70 ebay "generic" replacement will do the trick?

Example

Have looked at getting an OEM replacement but they are fairly pricey $400+

It's currently stock, I know I could do the delete and tune it, but really looking for a cheap solution.

Thanks

I removed mine a couple of months ago...

$30 ebay cable, 5 minutes to code it out, an hour or so to remove all the junk - gone for good

Thanks simon, you may be right, deleting it sounds like the cheapest route. I currently have the cable and VCDS ready to go

Can you just delete the pump and cap off the combi & box, or do you have to remove all 3 components inc Combi & N249?

With the resistors, did 30ohm 10w from Jaycar do the trick?

Cheers

yep, I just removed the pump and capped the combi and airbox (though I capped the combi at the head - no difference). I left the N249 in place and put a screw in the air line with a bit of sealant

I didn't use any resistors, because it's coded out in the map - the ECU doesn't go looking for it, doesn't try to turn it on - completely ignored

go here and download nefmoto flasher/logger: NefMoto ME7 ECU Flasher and Data Logger Version 1.9.3.2

read the instructions for reading your ECU and see if you can get a .bin file out of it. I'll help you from there

how'd you go? with nefmoto, in a nutshell you choose your cable from the drop-down, then click 'connect slow init', then on the 'KWP2000 Flashing' tab choose the "ME7 29F800BB.MemoryLayout.xml" file and click 'Full Read Flash' - takes about 3.5 minutes for my cable

Sorry for the late reply, hectic weekend!

Will try and have a go at it this weekend, seems straight fairly forward.. its on my mrs car which is stock tuned.

Thanks for the heads up on this program, Had no idea you could do this kind of stuff without a proper Ross tech cable.
I'm fairly tech savvy but haven't haven't had much luck getting my old blue KKL ebay cable to work as it appears to have a CH304T USB Chipset not compatible with the FTDI driver.. Nefmoto wont detect it. I'll shop around for a new cable

[simon k]

by the time I got it to work I'd bought 3 cables, first I didn't realise the CH304 chip wouldn't work, so I read more and found that the cable needs to have the FT232 chip, so I bought one of those, but when it arrived it had a CH304 chip, so then I bought this cable from this seller

but mine was $30 and came from Sydney (location said it was in Sydney, arrived in a few days)
