I'm persevering with mine after 1 years ownership but it hasn't been cheap so far;
Main Thermostat
Inline Thermostat
Ignition Switch
Lambda sensor
MAF sensor
PCV valve
Cam follower
Middle section exhaust
Plus usual costs like servicing and tyres etc.
When you think the car has done 110k miles so could do with
Suspension refresh - £1000?
Possible cam chain inc adjuster - £1000?
DSG service soon - £250?
Then if your dsg box goes you're in for a couple of grand bill....

when did your maf sensor go and what were your symptoms
It still isn't fixed! My car was mapped by previous owner and i added i 200 cell sports cat.
Started giving me the following codes with EML light;
P0100 - Mass or volume air flow sensor 'A' circuit
P1114 - Bank 1, sensor 2 internal resistance too high
P2196 - O2 sensor signal stuck rich bank 1 sensor 1
I arranged to get the map tweaked by the company that did the remap to suit any changes caused by the sports cat, when i got there they said i'd need a new o2/lambda sensor as the other one was damaged. All done and they said i shouldn't see these codes again. I also changed the maf sensor for a Hitachi one as recommended on here as a next best alternative to VAG.
After 3 weeks or so these 3 codes came back and have been coming back every month or so for the last 8 months. Each time i just clear the codes as i don't really know what to do having already replaced the lambda, MAF and had the map tweaked to suit new exhaust.
At no time has there been any effect on performance or MPG when these codes are showing so it doesn't seem too bad but it is annoying. If anyone has any thoughts would be interested to hear...
