Caddy DSG Gearbox Swap 104bhp gearbox- 170DSG gearbox

[Ollie370]

Can't believe the ecu for the box runs the 170 box, I know it's the same principle but some of these electrics are too clever for their own good. Glad it works, ill know how to fix my mates 105 TDI golf when it goes!

Great thread and massive help for my vw knowledge (Hondas before :-)

The ECU for the DSG gearbox is in the gearbox, so swapping gearbox swaps the ecu

How have you got on with the 170 box over this period? all good?

Might start the hunt for one for mine soon

I have (104) dsg which has only done 80,000 but is not very smoth and a bit sloopy.Vw told me there is no problem, but spoke to my mechanic and he said i must match engine numbers exactly. I am now excited and will start looking. Thanks for the great R&D.

You might not get a reply from the guys in this post, it is over 5 years since the last post.

I'd have thought any of the VW DQ250 boxes will work, just make sure it's from a diesel or the ratios and programming will be all wrong.
Golf, Passat, Touran, Sharan, Scirocco, A3, Leon, Octavia, Alhambra, Q3 (fwd) should all be suitable donors.
