whats wrong with it ?
coolant temp sensor - if its still a black topped one get a green on in there asap
if your still running the OEM diverter valve the 01 will have the older style which is very prone to splitting. the 03 onwards should have a redesigned part on - but mines still split before 30k. there are several variates available however they must be recirculating
check all vac lines around the engine. again these are prone to spliting - esp the Y joiner on the RHD of the head
brakes have 288mm discs on the front in the UK on the earlier models. im guessing your do as well. get the calliper carriers ( most scrappies will sell them with the callipers on but they, the callipers, are the same as you have ) off a TT and you can fit your callipers to the 312mm disc. from here you can further upgrade to porsche callipers
(see my thread for details)
if theres no errors on the engine and you cant find and split hoses then look at remapping it. the AUM engine in the 01 will map from 150 up to around 210. next up for preformance would be the downpipe and a sports cat along with Turbo Intake Pipe (TIP)
front mount intercooler - your temps at least warrant having one quite quickly along with the map tweaked and you should be seeing around 230.
after this your really needing to change to a better turbo
