UrS4 2.2T Sedan project

[Squbbe]

Was your manifold made of stainless steel? At least they are prone for cracking. Also I have a couple of questions, I'm rebuilding my urS4 rear subframe (bought one with rear sway bar) and wondering how do the yellow track polyurethane bushings feel? Do you have more vibrations and noise and how about the steering feedback? And one more question: do rear and front bumpers fit from urS6 avant to urS4 sedan (I think you got them from avant)?

Well today was not a good day. I found out that i got a crack in my exhaust manifold. Realised something was wrong when i saw some black colored exhaust wrapping, when i removed it i saw the crack. Will remove the em and send it to CP-S for repair. Does many other people have issues with their EM cracking? Did this happend because i didn't have a support bracket for the turbo? Sucks either way.. Unfortunately i wont make it to the Nordic Audi meeting next weekend. Bad timing for sure... Otherwise i'm waiting for the fuel pressure adapter that Jonas_r are making. Then i will connect a fuel pressure sensor to the Maxxecu so i can logg/see fuel pressure.

Pass Mot

So today i passed MOT inspection

Before adjusting lamda correction:

After adjusting lambda correction:

According to their measure instrument it runs a bit lean but this is only during low load.
So now i just have to take away my turboshield, cat and muffler. Then it is ready for the summer.

Adjusted lambda

So i found by looking at som log files that it runs rich on idle. Found out that the lambda regulation was limited to adjust -15% on idle, so i adjusted it further down until i reached the lambda target (1.000). Got a little bit ruff idle but i think it will slip through MOT now. Will see if i can get it to the MOT tomorrow..

Ask the OEM, as far as I know they have solution for acceptable emissions

Didn't pass MOT

The car didn't pass MOT due to wrong Lambda value (0,94), high HC and high CO. Will look at the Maxxecu file to see if something is wrong with the Lambda regulation. Because some times it has hard to keep Lambda 1.0 at idle, even if that's the Lambda target. Other than that he let it through

Away from the eyes = away from the mind

That MOT guy has juas the right attitude. My MOT guy was like looking in the engine bay and ignored the big turbo because his eye caught the changed intercooler.

Hehe! Yeah it's all about the guy who's making the inspection. If he is in bad mood he will not let it through. A MOT guy once told me, "Your car is tuned right? But as long it's not faster than my 500hp Evo I let it pass"

Why would you need a cover? (btw looks well cool)

[Thuppu]

Haha, nice!

[s0_big]

yeah

I now that it's obvious but since he told me to do it i did. Maybe it feels better to let the car through the MOT if it's not a big turbo that pops up first thing when you open the hood. But as always, he must be a nice guy to let it through.

Nice cover, but isn't it a little bit obvious, that something is hidden under it? IMO, it would look more stealth in black color.
