Hot Weather Fuel Problems

Audi A4 2003 2.0 FSI 180000 miles
My 2003 A4 2.0 TFSI badly misfires either in very hot weather or after driving a long distance of around 40 miles but becomes ok as soon as it is re-fuelled. This seems to suggest a problem with the fuel system being affected by heat. Any idea what the particular problem could be please? It is so frustrating as it even sometimes stalls in such conditions when in slow traffic.

Lights flashing

Audi A4 2006 Manual  150000 miles
I have an oil pressure sign on the glow plug sign is flashing the ESP warning is on. I've been losing power every so often driving and today I was over taking and all the above warning lights have come on.
I pulled over turned car off and waited when I went to turn car back on it took a while to turn over and start, I wasn't far from home so I turned round and headed the 15min drive back half way hm battery light came on as well and car died so I waited and got it going again it took a bit to turn over. I got home its booked in with an Audi garage tomorrow but being a girl I would like a rough idea of what's going on any ideas thanks

White smoke

Audi A4 2011 2 litre sline 83500 miles
White smoke pouring from exhaust. Car runs fine and has been checked over by mechanics and they have cleared dpf and no fault codes showing up. No fluid leaks. One day it's fine and the next it just starts pouring with white smoke, at a complete loss as to what the problem could be.

I had something similar... I found out our little one put coins in the CD player and only every now and again would it short out the circuitry so ended up taking out the radio and opened it up somebit to get the coins out... possible help for you?

Not starting

Audi A4 2005 2l tdi 170580 miles
Got in my audi a4 earlier (2005 model) turned the ignition on... nothing working on the dash apart from the handbrake light and airbag light. Crank it, starts briefly then died. Won't start, dash lights and gauges not functioning at all! now i know that if it starts then dies straight away it's usually an immobiliser issue, but why would the dash not work? long shot, but anyone had this before? i know there are a few people on here with a4's, passats etc

I have the same problem to solve the problem is to recondition the engine at a cost of about $10,000. A bloody joke.

Audi iPhone screeching speaker noise

Audi A4 2007 Convertible Quatro 3.2L 180000 miles
I recently got a new iPhone 6s Plus , had it two weeks and all of a sudden the speakers turn full volume ear piercing screeching static, you cannot turn the volume down and when you shut off the car the noise keeps going for a few minutes when you walk away. I had the amp and radio all checked out and it turns out that when I turn Bluetooth on it starts the noise immediately, I have shut the blue tooth off and no issues only I have to wear a headset. Any ideas would be great as I have to exchange the phone for an android or sell the car. Called Apple and they admitted there is an issue and trying to solve it which could be weeks, months etc. Not a popular problem so I don't expect a solution anytime soon.
Any feedback would be greatly appreciated.
Thanks you
