After what feels like forever, I have some progress (touch wood!)... The newly rebuilt charger from Only Charged Dubs arrived yesterday so it was all hands to the pump to get it fitted before the weekend. Got the old one removed (again) and then fitted the new one, fitted the new oil feed and return pipes and carried out an engine flush and oil change with the correct grade of oil 10w40 Semi Synthetic. Primed the new charger as per the instructions, and then let the car idle and got the engine up to temperature to check for leaks etc. After a few adjustments, it was started again and after a few minutes I slowly increased the revs from idle upto 1000rpm, 1500rpm, 2000rpm and then 2200rpm when I heard what can only be described as a scary noise! Almost like a buzzing from the charger area. Checked the oil feed pipe, yep plenty of oil in there. By this time, it was getting late and I'd had enough for one evening, so I packed everything away and thought I'd tackle it again in the morning with after some sleep... Saturday morning and I started the car up and again let it idle up to temperature, another quick check in the daytime for leaks was also done. Increased the revs as I had done the previous day and the noise returned. I phoned OCD and spoke to Matt who said that you can sometimes get noises from the chargers after a rebuild, and to take the car for a drive and see how I got on, which I did. At first the noise remained, and I was ready to admit defeat when after a longer drive at a constant RPM, the noise got quieter! I carried on driving, and the more I was driving the better the noise got! Now I'm not sure if this is normal, or anyone has come across this before (would be good to hear if anyone has), but long story short I have covered 80 miles today with varying loads whilst keeping the RPM under 3000RPM as per the instructions for running in, and the noise has gone completely and I'm just left with the hollow G60 noise (hard to describe) that from what I can work out, is normal. So fingers crossed all is good now, and I can start to enjoy Corrado ownership again! I'm guessing that the oil just needed to get to all the right places within the charger and driving it more obviously got the lubrication to where it needed to go, and perhaps it was a slightly dry seal thats now been lubricated? Who know's I'm not that clued up on G-Laders but as long as that noise stays away and the boost stays within the engine then I'm happy!

Wow, got that wrong. TDI's looking good though
