No fault code found is a good thing

Thanks dom, PHEW! so what is this referring to? is it just telling me its scanned these items and found nothing?? It did pop up earlier with the temp sensor implausable signal fault but i cleared that because i replaced the temp sensor the other day. thought my ecu was buggered for a min. although i've heard that some people have had patterned temp sensors that haven't worked properly.
How bad can these things make your car run when they go because mine is running like a bag of poo. changing it has def improved starting and idle but my gauge is still dropping right down on open roads and i can only boost for a few seconds before it feels like i have some sort of blockage and it holds right back.

Just to clarify because ive checked quite alot....

*Replaced Coolant temp sensor (as per fault code on my scanner) came up again on vagcom again today?

*Checked for air leaks- found one and replaced hose/pipe.

*Replaced N75 valve as old one was really stiff.

*Found broken wire going to N75. Replaced wiring & harness

*Found Ignition amp dangling on a cable tie - remounted a replacement ignition amp back in its original place. have swapped these a few times (same 2) and made no difference.

*Disconnected MAF, no difference in driving. also gave this a good clean.

*Added fuel treatment (slick50) had a good drive on open roads for 40+ miles working the throttle to try n clear the system.

*Checked wiring to N75. 0volts with no ignition, 5-6volts with ignition??

in my mind the things i want to check the lite version of vagcom wont let me do.
i want to check the N75, TPS(does the cable throttle AGU have 1?). check fuel system(filters, injectors, valves). double,double check the ignition (surely my software would spot a misfire?) thermostat? inlet manifold, actuator and turbo. the reason i ask about the TPS or equivilent is because i fitted my amp&stereo not long ago and had the battery off the car for quite a few hours(been reading up). would this of reset the TPS and need calibrating again or are they self calibrating??(if i have 1)
I know its alot to take in but i cant bear it getting the better of me. i know a fair bit about cars and what can cause similar symptons to mine but this has left me baffled...
Last thing guys, on vagcom, if the values of what you are reading are GREEN is this a good reading?? do they turn RED when they're too high or low. again thanks for any input on this. youre help is much appreciated.

FINALLY FIXED IT!!! It has taken me ages to find the fault causing my problems but today I found the little bugger. It was the fuel pressure regulator!!! I have basically had a combination of things wrong causing it to not run properly. But now they're all sorted and it's running sweet again!! Here's a little list of what I found wrong and rectified 1 by 1.

-coolant temp sensor x3! 2 dodgy cheap ones (live and learn) and a genuine one.

-various vacuum & PVC hose leaks, all dodgy hoses replaced, 1 under the fannymould had a hole I could put my finger in!

-N75 valve was seized solid. Bought a new genuine 1 also replaced dodgy wiring to N75.

-Ignition amp was getting too hot as it was just dangling on its wire so I cut up an old air box and mounted a new one properly next to my air filter.

-Thermostat stuck. Replaced with genuine new one.
and finally....

-Fuel pressure regulator, the one in there was a patterned part and the hole in it is considerably smaller than the genuine one I fitted today.

Glad I stuck with it, not sure how it was even running with all the problems it had. Each fault I fixed made an improvement to the starting/running of the car but it was still holding back and not pulling very well at all. In a way I'm glad I didn't fix the fpr 1st as I probably would of left the rest of the faults without realising (except the coolant temp cos the gauge was playing up).
So I'd like to say a BIG THANK YOU to everyone who has posted all the useful info on this forum that I've trawled through night after night trying to get to the bottom of my problems. My local VW dealers (carrs) were pretty useless, paid them £45 for a plug in and they didn't have a clue. Then I took it to a local vw "specialist" who told me over the phone that I was getting a VAGCOM plug-in but didn't take it to his garage that day so couldn't read any live data and basically told me the same as vw did. Now I just need a new battery cos having to start it twice most times for the last god knows how long has taken it's toll, dear of it. Soz for the rant but I'm soooo chuffed I fixed it myself with the help of you guys. Thanks again.
 Chazz. (Happy motorist)
