From an earlier post I recall reading that there are many different springs depending on the cars weight and set up, so I'd hazard a guess that these FSi components won't be compatible with your TDi - but lets wait for someone who knows what theyre on about!!
Parts are from an 03 FSI SE.
They are original, appart from one spring which was replaced in january.
Car had done 53,000 miles on these dampers and they are in good condition.
