Well. I finally found a company called CCM in Ewhurst who were happy to help. Full dynamic flush with ZF long life with filter change. Not cheap but I am happy with the result.

I have contacted Liqui Moly and await a reply on a nearer approved service center, so see what happens there. The gearbox shifts fine apart from a little hesitation sometimes when lifting off upon going downhill (gentle nudge is felt). Electro chap came round. It's electro mechanical interference ...

Ha I've been caught out by the exact same thing. My S8's compressor is also grumbling at the moment too. They are only £200 for NRF units which seem to work pretty well. Should be about an hour's work for a garage with an AC machine to change it. Aha! found two VAG.... 'specialists'. Discussed ...

So...... I followed the process advised by MJ. Managed about 125mls oil. Not fun scrabbling around underneath a car with the motor running. Cleaned up. Car back on the ground and went for a spin......... whine still there! Guess what? Pressing the AC econ switch on and the noise went away!!!! I feel ...

What is the plan for this one?

Skoda 2.7 biturbo?

OK. So I took a little look online regarding 'topping up' and it has filled me with a small sense of horror over all sorts of procedures. I was just going to remove the bottom plug - as I understand that's where the fill level is anyway - and add more in using my trusty bit syringe and a rubber tube ...

Thanks Guys.... I am going to err on the side of caution and cancel the gearbox oil change, for now. Like the idea that Ronin suggested. Nobody wants to do a check and top up so I guess I am crawling under the car in the next few days to inspect and top up through the 'official' fill up hole. I have ...

Getting another?

Well, it has only been 10,000 miles since MJ worked her magic on the 'Barn Find, Lazavus' but I am feeling that a gearbox service is needed. Its because when I did the radiator replacement (and the obligatory top up - 200ml?) I am sure that now hearing a low pitched whine from the torque converter ...

Worked a treat!

Thanks Ronin.
