Swirl Motor - cheap replacement solution (Pennies!)

Came home, disconnected the dead Swirl Motor and just inserted the resistor into the Swirl Plug pings on the Grey PWM signal wire and the live Red/Green wire. The middle two on mine.

Ignition on, cleared codes on OBDII reader and fired her up. No further DTC codes, no MIL light, no ETC light.

Now its confirmed, I'll do a proper connection on it with spade connectors etc.

Big thanks to all those who've offered advice!!

that 1st photo is a bit blurred...the resistor wire seems to go into socket #3 (top to bottom), does it also go into #2 (because the wire at upper end of the resistor doesnt seem to be attached)? (I'm guessing 2 & 3 from previous posts). Being ignorant of transistors, does it matter which way round its fitted?

for owners who have a working swirl motor at present, it may well be worth making up a spade connector / resistor set & keeping it in the glovebox JIC youre away from home & drop into 'limp' mode with a failure....... nothing would be guaranteed more than to have it happen on a holiday in France, for instance!


on a £600 repair, I reckon a £599.74 saving is probably worth having!

I'll alter the title of this thread & sticky it here & in Australia

Apologies for the quality of the first photo, taken on an iPhone. The resistor went in the two middle pins on my socket, #2 and #3, mine was a 4 pin connector but only 3 of them were used.

I just folded over the legs of the resistor and inserted them into the plug to make them fit whilst I fired the engine up and cleared the codes.

This type of resistor has no 'positive' or 'negative' end, so it doesn't matter which way around it goes.

What size spades are they? as i think i will make one as Miles says, just incase.

Can you get to the multi-plug without any tools??

Thanks KB for making my thread a sticky, I will try and get some decent pics from my car including a more permanent solution and also some pics of the EGR mod.

I need to check the size of the spades,
If you check my post no 32 that will explain how to get at the plug.

I would recommend using a metal film resistor - a bit more expensive, but better stability at high ambient temps (70C). Stocked by Maplin.

EGR mod is a stainless steel plate or an ECU remap Al

Back in February, B4rry1717 had a swirl emulator fitted by simon@thecustom300cshop. Is anyone able to confirm that its still working OK?

I think it may be usefull to have a record of the cars with the mod, any owners who have took the option and gave it a go could give a mention here, and any problems if they crop up.

For the owners that need a bit of direction i will sort some pics etc as soon as i get chance.

Pic 1 shows how to fashion the resistor to fit the plug

pic 2 is insulated swirl plug on top of fuel filter

pic3+4 show the resistor fitted in the plug...this is the EGR plug but swirl is similar but uses the 2 centre pins

pic 5 shows my intake pipe with 2x maf sensors

be sure to insulate well with tape

This is a temporary fix till i sort something permanent.
