Mine's a 2008 2.0 TDCI. I don't go with 'one size fits all' plug and play chips. Can recommend Angel Tuning (http://www.angeltuning.co.uk/engine-rem ... uning.aspx) which I had done about 18 months ago. They do a custom remap for your vehicle plus a decent air filter for about £300. (As MC-Junior says, you need to spend for the sake of the engine). They do a test drive, diagnostic, download and adjust the files, upload the remapped files then do a final diagnostics and test drive. Worked for me! Good luck. Phil.
