SMF?

[ecala001]

I have an 2011 audi a3 and was wondering if a SMF would work. if so what cars smf would fit since I'll be hitting the yard? or if welding it shut would work?

 

[IndigoBlueWagon]

I assume this is an automatic. If so, no SMF for that transmission.

bummer. I wanted to swap a manual conversion but seems like it's all in Europe

The 2011 Audi A3 Sportback is essentially a late 5th gen Golf, there are manual bits here, if you wanted to swap it. Any CBEA or CJAA Golf or J-wagen should be able to provide most of it, and some of it could also come from a Beetle or NCS Jetta (at least the transmission itself could, not sure about the pedals and shifter though).

There were also gasoline fueled Sportbacks sold here that could provide everything BUT the transmission.

Sucks that all the A3 TDIs were automatic for us, though.

sweet! I'll be grabbing the tranny from those. 09-14 tdi I believe

If you do conversion , You will need to run DMF.
There is many reports that first gear gets damage and you can look here :

looks like I was able to find a 2012 vw golf tdi at the yard.
wondering if I get the tranny and all the other parts if I would need a tune for any error codes because of the tranny?

ECU will probably complain about Auto tranny and on those cars usually ECU software is made for either Manual or Automatic so re=coding will not work.
Beeing that there is no Manul transmission here is USA for A3 , the question is how to make it work . Probably some Custom made software

 

[oilhammer]

Software change is all, no different than a manual Golf or Jetta with the same engine. VAG has boatloads of part numbers for ECUs based on calibration and such, but they can all have the same software flashed to them. No big deal other than the CR ECUs need to be unlocked, but the tuners figured that out years ago.

Just the ALH engines... they'll show six different ECUs for a 2002 model year, but we all know any one of them can be used interchangeably.

People have already manual-swapped CR Volkswagens that were DSGs, the Audi cannot be any different.

Here's an Audi A3 (not tdi) that got swapped without flashing the ecu

This may be a bit of a hot take, but I'd argue that going from a (tuned and maintained) DCG to a manual transmission is somewhat of a downgrade. The dual clutch trans in these cars is absolutely amazing.
The only way I would consider it is if it came with an AWD swap as well.

The Audi A3 is a CBEA engine and it's not going to be very happy with a SMF. It has balancer shafts that the CJAA does not. If you must go SMF I would add the fluidampr harmonic balancer to improve engine reliability from the loss of dampening

I don't understand this. Why wouldn't the balance shaft help, not hurt?

Usually when someone wants a manual swap it's not because of performance, or even logic. It's because they want a manual. I get it. Three pedals are still the best.

The balancer shafts help with engine vibration but not directly with crankshaft torsion, as they are gear driven. The SMF does not help either but I have had very good luck with the fluidampr's taming vibration.

Did you read post #6, CR and SMF are no good at all.

CBEA vs CJAA .
ECU looks same but different software .
I doubt CJAA ECU will work plug and play . And also Second hand ECU needs to be programed or Immobilizer delete .

is the electrical portion the same as a tdi?

 

[ecala001]

so I was able to swap the 2012 vw tdi golf 02q tranny into the 2011 audi a3 tdi

got the reverse lights going, but stuck on pin 2, 4, and 5. Car won't start so I think I have wiring wrong.

was able to remove auto from gateway list of vcds and cluster now shows to press clutch to start. Might need to send to malone to do the rest

 

[ecala001]

update.

got it to start now had to switch wires from t52b to t52c. Cluster shows press clutch when starting.

hopefully with a DMF!
a SMF will wreck your shift forks and likely syncro's!

Well done!! Must've felt pretty good when it fired up for you.

yeah it's a dmf from the 02q tranny

 

[ecala001]

it did feel good. found kerma can help me program the ecm to recognize the tranny. Odd that malone couldn't do it

 

[lemoncurd]

there is alot they cant, rather wont, do lately..

glad kerma got you squared away. fwiw kerma cant do emission deletes, but otherwise his tunes are very good from what i have heard

yeah I think cuz they are based in the US and the other tuners are out of country. at least they are able to do it. I just need it on my stock ecu
