I have access to a gaz analysor, will do asap.
it's just that I didn't do it since I installed new injectors and rebuilt
the control pressure regulator
did not think it would change that much.
last tech check CO was 3.4

again, Meyle HD. Meyle rocks !
I'll pass the ref when I retrieve it.
wanted to get Mance stuff but he asks way too much.

I think axle weights don't directly add up to total weight ?
the driver manual says total weight is 1300kg "ready to drive" (with
anyway, don't take those datas for granted.
just for the kicks, I retrieved the last check datas and they are totally 
this time it said : front 800kg, rear 541,
previous tests gave 775/352 and 761/483, go figure !

A4 front (Porsche red, baby...), stock rear (not rebuilt)
obviously rear left is a bit weak
I swapped the sides on the handbrake datas : L 180 R 201
again, previous datas were a lot different, got way higher values
brakes bench clearly out of calibration...
but what can I say ? they're "the law" !

no, the sounds comes from the steering rack and it's clearly an hydraulic
bubbling/cavitation sound

because I'm super dope, buddy :-)
no, really, you believe I'm gonna struggle 15 years on that rust bucket ?
soon it'll make you just cry of jealousy ! ;-)
it already made you sh*t in your pants and got you deaf for a while, do I 
have to recall ? lol.
