Has anyone ever tried using a separate throttle pot, as mentioned in the S4 2.7T Self study document, with a car that was designed to have the throttle pot integrated into the throttle pedal?

I'm talking about using one of these:


In place of one of these:


Is this even possible? Do I need to recalibrate the throttle curve in the ECU? I'm hoping that the S4 has the twin potentiometer design like the AUQ pedal.

Two potentiometers, working inversely. If one reads 14, the other reads 86 (or thereabouts).

Switching to a single one will surely cause a fault.

You guessed right when you said 'mounting'. The engine is going in a T4 van, there is no nice way of mounting the electric pedal which came with the engine (from an AUQ Leon), but the 2.5 tdi vans came with a bracket and pedal to work with a seperate pot, hence I'd like to use a separate pot and save cutting the pedal box apart.

A bit of a skim of vagcat shows the seperate pot was fitted to the AUQ (along with the BAM and a bunch of other engines, including stuff like polo's from about 1995 onwards). Fingers crossed I can find one with the right resistance curve.

Cheers guys

Sorry about that, lots of long stressy hours in the garage welding engine mounts and not enough time in the pub!

I've had another look at the van and I think i can make the electric pedal fit well enough to get it running, while I try and source the floor mounted pot.
