A3 2.0 TDi chip

[daiA3Sline]

Has anyone bought and fitted one of these chip boxes that can be found on ebay for around £25? Click the link below to see what I mean:

VW Audi Seat Skoda TDI PD Diesel Tuning Chip (Golf VRS) - eBay Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (end time 22-Sep-07 11:58:48 BST)

Can anyone help????????????????

I am thinking of buying one but I am a little worried that it might damage my engine!

So, what do you think? Is it too good to be true?

Thanks

Absolute waste of time - don't waste your money.

All they contain is a 5p resistor that fools the engine into thinking that it is a different temperature than it really is - thus making the engine react slightly differently.

Given that VAG spent millions in research & development and go to the bother of installing a temp sensor so that they can vary the mapping depending on temperature, it doesn't make sense to bypass it....
