Hmmm. Something very not right. Another short circuit somewhere I think. Could your harness have melted again?

What a pain in the ass. :(

Oh well, at least you are experienced in dropping the engine.

I will try to see what is broken and put temporary hose if I can access the passenger wastegate

I know someone who's interested in this correlation between the wastegates actuators and the MAFs discrepancies. :wink:

I already spend several hours to extract and shifted the wastegate hoses, and another hour this afternoon to put the hose back

Hours of fun when you own an RS6.

Have you driven it since repairing the T piece? I guess you need to fix the lambda sensors, too.

I have not yet mounted the hose with the T not had a lot of time, the lambdas will be secondary I will do them with a bridge I must buy one and make a slab to rest on it is still a budget of 1500/2000 € after to work it will be more practical

Big trouble the hose is too hard to nibble, side passage is not even worth it I ended up recommend silicone hose 5 / 6mm internal necklace ears and brass T it arrives in the week it will be easier to install the the less I can install it ImageImageImageImage

Good idea. At least you won’t have to worry about it again. I wonder if Classk’s imbalance is coming from something similar.

it is very possible my leak must date for a moment t had to be split, to test it is necessary just to send air in the order of the wastegate
