If you run the car and then undo the oil cap, the cap shouldn't be to hard to lift. If it's very difficult (more vacuum) then most likely PVC. If when u remove the oil filler cap the engine will continue to run but struggles a bit, then PCV is good.
Mine has a slight judder at tickover. I have never found a solution. It feels like a miss, but really not sure. No codes when scanned. Any codes for you? That would be my next suggestion, get it scanned with vcds or similar. For me I tried, plugs, coil packs, PCV, full service including fuel filter and still the same. Mine is a 2.0 tfsi by the way.
Yes, all I know about mine is that sometimes it's fine, but sometime whilst stationary it feels like the car wobbles slightly, revs don't change but the wobble goes away if u apply a touch of throttle. Keep us posted on what you discover mate. Good luck.!
As mine is the 2.0tfsi I guess it's slightly different layout to the 1.8fsi. The only pipe I have from the throttle body is the quite thick one (about 2" wide). There are so many thinner hoses, but not sure what I'm checking if I'm honest. Also on my 2.0tfsi there are no pipes from near inlet that go to nothing. They are all connected up. Maybe a photo may help.
I would have though misfire would indicate one of the following. Spark plug, coil pack or coil pack loom. If I were you, I would swap coil pack on number 1 for coilpack number 3 or something. See if the fault follows the coilpack. If it stays at cylinder 1 then try swapping a spark plug over with the other. Then go from there.
Thing is, 99% of the time, it runs perfectly, on and off boost, low rpm, high, full chat.....
Sorry, i should have included the pre-info.
This car has had a new coil pack in cyl 1, after it failed the day after i bought it.
Its also had the head off at some point, owing to a snapped/slipped chain, and a bent valve.....Worrying that i can only find a invoice for ONE valve!!!!
Pulling the plugs will answer a few questions i guess !
Yes, I'd check the plugs for any clues. I'm not a mechanic but I have read quite a bit on here trying to resolve my judder issue. Yeah, you would have though more than one valve would have been affected. Stick some new plugs in if they haven't been changed for a long while. Good luck mate.
Hmmm. A tough one mate. I'd almost certainly contact the seat dealer asap. Tell them your problem, but I wouldn't say anything about work that was carried out. When did Audi do the work? Before u bought it? I would kick up such a fuss about them selling u a car not fit for purpose, and get them to pick it up and fix it, or get your money back. It's not your fault, you want to get it sorted one way or the other.!
Well. Work was done by audi in Aug 2014 at circa 67k. Currently 76.5. Audi customer service openly gave me the date and mileage, and the name of the audi dealer.
Called the dealer to enquire as to work done, met with a brick wall, data protection etc.
Didn't know the car had been in bits when I bought It. Found a hidden invoice for a timing chain.....
It certainly sounds unlucky. You've had it for less than a month. I'd highly advise u to get on the phone to Seat and get them to sort it. Be forceful if u need too, make sure they know your not happy.!!!! Even if it was an air leak, it needs to be sent back for them under sale of goods act.!
It sounds like a pain for you mate. If you went to any Audi dealer with your v5 and details etc, you can register as new owner of the car. Then they have to tell u what the history of the work done was, data protection wouldn't be an obstacle then. Does sound odd about just the one valve. Let us know how u get on.
Wow, I wonder if a set of new plugs will fix it for you then. But where has the part of the plug gone?? I wonder if Audi actually replaced the plugs when they carried out the work, or whether they forgot to check them. Let's hope a new set is all that's needed.!!!
Ahhhh nice one. Pleased it looks to be sorted.! As for the water I'd look for water at the hoses from expansion tank, around the radiator, around the head gasket area and around the water pump. Just to get u started, lol.
The only thing I can suggest, which is actually very very handy, is to go to this website that shows all Audi models, part numbers and diagrams. Take a good look through and see if you can determine whether there should be a hose connected. This is like the bible so treat it well. www.partsbase.org/audi
