Well on inspection of the cam adjuster when I replaced the three plastic rings, I have wear grooves inside due to mine being an early 2005 GTI that had the metal rings originally, so it wore out quicker..........but all wear with time even with the new plastic ring alternative.
Similar to the AKS image here:

Had a quote from TPS and it is £700 for only the adjuster then additional parts like the chain, tensioner, gaskets etc make it in the £1000 ball park.......... and can not bring myself to spend that on this good, old car.
I was thinking of getting an INA one as the rest of the stuff on the car is perfect.....new genuine chain and tensioner done a few years ago etc
Am I being sensible getting the INA part at about £180
