What is the WURTH product Steve?

[Phil Mcavity]

Not sure, have spoken to Shaun (T_T) and aparently its more up to date product and better on newer engines then the oil school wynns.

I will try and find out.....

This problem was more of a problem in america isnt it??

They use crap fuel 94 octane?? and 502 grade oil, which our longlife oil is alot better quality, so this issue may or may not be a major problem?

Can you honestly look at the pic of what SteveP's car collected in the catch can over 2k miles and think that the problem is confined to the US?

It's an inherent design "flaw" of the FSI engine.

yes but what oil was in jonnys engine? Was it on 504 longlife?

And have we seen a pic of steveP's valves to proove?, and has he had any bhp problems...His car has done quite a few thousand miles and no running issues.
I think a can of this Wurth stuff is worth a punt incase mine has any issues in future.

hmm, I can't see that product helping with this issue as the fuel is sprayed directly into the cylinder leaving the inlet valves "untouched".

But you spray this into the intake ducts, which goes via the valves and would clean it surely?

[vRStu]

It is a known and accepted problem Steve.  It was recently featured in Audi Driver magazine.

I've also emailed Wurth to see what they've got to say.

Usage -

Disconnect vacuum hose at a suitable point and insert Spray Probe (0891 564). With the engine warm and running at about 2000 rpm, spray half of the product evenly into all intake ducts whilst simultaneously moving the probe to and fro. Allow 30 minutes for the product to take effect and then add the rest of the product.

Any link on the net to this stu? or sneaky read at whsmiths?  

[vRStu]

I'm sad enough to get it delivered.

Ahh, thought it was for just adding to the petrol.

I think it's in the TTRS issue which seems to be the only link not working.
