I am thinking about getting a desiel tuning box for my Audi a3 1.6 tdi sport back 8va. Was hopping for a bit of advice on witch to get as I've neva had one and been looking online and there's too many to choose from. And dont want to pay a foutune for it and leaning more towards eco than power. Am not interested in a remap as car is still under warranty. All help is appreciated and many thanks

Is it worth it? My 1.6tdi was good for 50mpg and sometimes 60mpg+ on a trip. Not sure you will notice much better than that. Even an extra 10mpg will cost you quite a bit to recoup against the cost of a tuning box.

I've been told that it won't cos they carnt tell it's been fitted
They can't and, up until 2019 they still haven't. You should refer to those who know the boxes and not those who just engage in forum trolling...

ODIS (Offboard Diagnostic System)
Modern engine control units, and transmission control units, store a massive amount of information such as boost level, fueling information and throttle position etc. If the stored values are found to be outside normal operating thresholds then the official VW Group service tool will flag this and prompt a technician to conduct further physical investigation, ie looking for unusual marks / damage around connectors, clean spots on connectors or looms in an otherwise dirty engine bay etc etc, in other words look for signs that something has been installed and removed. Any / all observations can be used by Audi / VW Group to void warranty. My advise... tuning boxes are ok, mapping is always king but you can get a decent performance boost from a box. When due a service or any warranty related works remove the box and drive the car stock for 3 to 4 days in order to "store" stock settings and flush out the "modified ones", then clean your car an especially your engine bay.

Validate please...

Honestly it's 2020 , how blind do you have to be , just £120 hand held vehicle diagnostics are very detailed in the last 5 years , my iCarsoft told me the airfilter had 8% contamination !

You honestly think that full dealer detailed diagnostics can't tell a tuning box has been fitted and removed , give over , what a joke .

They wouldn't have a TB1 code if they couldn't detect it !

leaning more towards eco than power.

I'd be very surprised if a box would improve economy. The reality is unless on idle or overrun the box is just fooling the ECU into tipping more fuel in than it intends. That would increase the ECU's calculated MPG without improving economy in any way, also possibly filling your DPF with extra soot under certain conditions.

A TB1 code is a "suspected tuning box" code.
With any kind of tuning you take the risk and have to be prepared for the worst if something goes wrong. But then you'd be mad to send the car in with it still attached, so remove it and delete the subsequent fault codes and I'd be amazed if anything came of it.
I'd get a tuning box with as many connections as possible as the basic ones just chuck more fuel in and let the ecu alter everything else.
I've only ever used MTM M cantronic and JB4 for that reason as they connect to the canbus
