Ye i would put another engine in aswel mate wouldnt be able to let it go either. Well thats not fair got ages to wait lol. Come on people get tickets brought need to get the club stand sorted

Hi all once again, So after many many hours of researching and with my face stuck in my engine bay, im coming to the end of my limited Audi engine knowledge and im hoping, if not praying that someone here might be able to help. My 8p runs beautifully out on the road, but at stops or while its idling it just doesnt feel right, its not a really bad shake but it definitely sounds like some sort of a misfire. So much investigation has gone into trying to find the culprit, I've replaced plugs, leads, cleaned the throttle body/manifold/all piping. Checked for air leaks, replaced perished pipes, had it compression tested, valves checked, had it a mechanic who told me it needed a remap (godshite), had it to audi who couldn't tell me with their diagnostics and wanted to charge me an arm and a leg for further investigation. I was told it could be the egr valve or the map sensor, changed both to new ones and still the same.... So today I go at it again, checking everything that I can and cleaning what I can and ran it on VCDS diagnostics, Im now getting an error code (16784) for my (wait for it), egr valve!! Which I never had before, typical right? I've also got a fresh one which is obviously linked to the other: (16891) 'idle control system rpm, higher then expected ' Both are intermittent though. List of things done already over the past couple of days New brake light switch New egr valve New ignition leads New ignition coil New oil pressure sensor With a bit of reading up i read it could possibly be the PCV/PVR/Crankcase Breather Valve, which i have purchased today but have no idea where it is located on my 2004 8p engine so if anyone can help there please do!! Heres a link for reference: https://www.micksgarage.com/d/crankcase-breather-parts/audi/audi-a3/a3-2003-to-2012/1-6-102-1595/products Was also told its possibly my crankshaft sensor but Im hesitant as its not showing up on VCDS as faulty... Im also noticing it has a light, almost white smoke coming from my exhaust at revs above 3000 rpm from idle. Sorry for the essay but please can anyone share some light or had similar problems? My heart is broken at this stage and I've got an 800kms trip to cover next week Tyia and much love [/IMG] MOV_0247.mp4

nice motor Andrew, welcome to the clan

Welcome to the forum Andrew :) loveky look s4 you have there! Youll find the members on here are a friendly and helpful bunch and if you have any questions then don't hesitate to ask :) cheers steve

😂 I am just poor!!

thanks Dan, never thought to place cardboard on floor. Doh ! I usually wash it after clay to get rid of anything then microfibre then polish. I love a shiney car, my last MX5 this year =

Totally fine to use on metallic as it's covered in a clear coat lacquer. I use Bilt Hamber clay bar. It's very soft so easy to grip. A good tip though is have a big peice of cardboard under area you are using it so if it drops it stays clean 👍 Always remember to at least wash car again with a wax wash but much better to polish to protect the clean paintwork. It's amazing how many times people forget to polish thinking the clay bar is a final thing. (Not saying you do mate though)

I am still getting used the engine names but I think the 8P is a petrol? If you are getting white smoke then the only cause can really be water ingress. (I am happy to be corrected here btw). Is your water level going down at all? Does you car have an EGR cooler? These seem to be prone to leak on VAG engines. When your engine is warm, but switched off. Carefully open the coolant expansion tank, you don't need to remove the lid fully, just release some pressure. If you see loads of bubbles rushing into the tank then it's a good sign that the head gasket has gone or the head has cracked! Redex is a good enough injector cleaner, try a double dose in a half tank and drive it for a few miles. Then fill it up and drive as normal. keep us updated!

I have the same problem with my 2006 1.6 petrol! It's doing my head in! I'll be following this topic in hope of finding an answer

Hey Trevor and thanks for the reply, thought it might be just you and me in here ;) Any recommendations on a good fuel system cleaner? Ive been adding Redex to the last couple of fill ups to give the injectors a little clean, noticing the difference top end but with revs below 2k its the very same. Went out yesterday and removed the egr valve again, checked all pipes and cleaned with carb cleaner once again, checked the gaskets etc and everything seems to be fine. Its very frustrating at this point, almost ready to throw in the towel and get it to a mechanic :(

I would start by running some strong cleaner through the fuel system, remove the EGR and clean/delete and then look at the obvious stuff again, you may have missed something (it happens) p.s. all of the above costs very little money and is where I would start if I were sorting the fault.

Exactly! Dont worry, it'll come round quick lol we do need more people to confirm they've bought tickets!

Exactly! That's what's stopping me from going.

Hi Mark, I have just feed a Halfords Exodus 470 onto my A6 with Square roof bars. My roof box came with the quick fit brackets that have a U bolt past up through the underside of the box. These have an internal width of 80mm so should be wide enough for your aero bars. I purchased my box new after getting 10% off online and an additional 16% discount for using friends and family card. In all it cost me £189. I was also looking all over Ebay for a box but they were all going for silly money unless they were in a state.

About 2 months, the forum has a good feel to it. Have a few too many cars tbh but my 4 circles is an A6, always wanted the 2.7 V6, it's a very sweet running engine.

just testing a pic hosting site

Thanks for the welcomes guys! I've already identified a couple of areas that need sorting, the usual ones like milky areas on trim, intermittent glow-plug light warnings etc. But it drives very well and the 2.5 TD has loads of grunt doesn't it!

Yes! I got one right for once lol heres the next one...

Correct!!

Great info their Trevor! :)
