Try resetting the Motronic and just run on petrol and see what the afr is like.

There was bunch if codes saved, most due to removed plugs while doing work. So that's all cleared now and tomorrow before leaving for work I'll remove battery for 5 minutes to reset motronic and see if she runs better.

Seems to be fixed now. Glad it wasn't anything expensive And I'm pretty sure no more shaking either, 1st gear through whole rev range and she's not missing a beat. Hope to make de-cat pipes in next month or so, that should make breathing easier and emmisions won't be a problem as it was only 1/3 of what's allowed. had to lay injectors flat as it damaged bonnet by siting too high

Happiness short lived. While driving I get 00515 code which is Camshaft Position (Hall) Sensor (G40): No Signal and then car runs like described yesterday.

But should car stop running altogether?

[hunker7]

Might have found a problem. I changed the sensor so I knew it's not that, so checked the plug and it looks like this. Ordered one from Audi, should be here Tuesday. Fingers crossed.

Hopefully this sorts out your problems.

I think what happens is it loosea connection for a second and once code is stored it's messing things up. I'll try taking it apart tomorrow and get it connected properly somehow so it works fine till Tuesday.

Had to install narrow band back in as I was getting 00515 code which I would think i's due to simulated output.

Where is best place to weld 2nd bung to have both running?

[diesel des]

Close to the original. I have one behind the other.

Sorry to be pain in the **** but I'm still getting mixture adaptation error and no check engine light. Running narrowband currently. Don't know how to get rid of it and doubt giving car to someone will help.

[hunker7]

I thought I'll update this with how I'm doing after installing wide band and adjusting everything with help from Des. Since installing wide band I've done about 2500 miles and she runs like a dream. Personally can't see any difference in behaviour of the car, response is the same, boosts same and goes as well in general. Fuel economy has dropped as expected. Getting about 19mpg on a longer run, goes up to about 22mpg if keeping revs below 3000rpm

Going to work and back I used to put in about 20-25 quid worth of fuel every week, now tenner is plenty enough, and that's without watching out how I drive.

I do very rarely get check engine light on cruise which I assume is mixture adaptation but it happens for a second or 2 and then it's all back to normal, so nothing I'm worried about.

I want to dyno her on both fuels and see the difference if any, but that's when I fix up the exhaust.

Glad to here your sorted now. Lpg is impressive when done right.

I'm very happy I did it, won't take long till it pays for itself and starts saving me money. And knowing that I'm covered for RS2+ spec power is good too.

[hunker7]

Mixture goes lean under boost? Any ideas? Runs perfectly on petrol. Checked for codes and nothing out if ordinary.
