FYI: This is what it takes to clean the carbon build-up in FSI engines due to our "low grade fuel" in NA.
The service department manager at Audi Halifax tells me that some serious re-engineering is likely to take place to address this issue and that BMW are having similar problems. To clean the ports using a little wire brush on a flexible shaft, took just 30 mins. The entire job took 19.2 hours due to the need for dropping and replacing the entire engine and gearbox assembly. |
WOW !
Quite a major surgery event, isn't it ? Is this occurring on the v6 engine only ? Did they say why ? Is it due to these factors ? 1) Too little flow in that area 2) Cooling too quickly to allow the deposit of the carbon from insufficient burn rate. 3) Too few HARD acceleration runs to 'clean' out the engine :) (this will never be a problem on my wife's cars :) ) |
:eek: How many mile are on this engine?????
|
Whoa! Is there some type fuel system additive that can help prevent that? Maybe like seafoam or something. Its hard to imagine that Europe has better quality fuel than N.A., I would think it would be on par. Wonder if it has to do with the crap Ethanol that we blend in?

LOTS of questions, few answers and a lot of speculation, unfortunately.
The car has 138,000km, mostly highway, I am a spirited driver around town and open it up on back roads every now and again. Apparently it's not an issue of heat/cooling or driving habits, simply that Europe get's high grade fuel from Saudi Arabia (light crude) while NA uses lower grade fuels like Venezuela crude and tar sands crude. European Octane levels are higher (98-100) while we get 91-93 at max. In Europe they simply don't have this issue and if they had it would have been addressed long before. |
In looking at the picture, it looks like the gasoline was derived from the Athabascan oil sands. Are you sure it's not just a provincial plot against NS?;)
On the serious side, was this covered under warranty? |

They previously had around 5% ethanol in the gas, and last year they tried to market the E10 gas (10%)...but the Germans don't want to put it in their nice cars, so it's looking like an epic fail! |
