Engine noise

Audi A4 2003
When I bought my Audi fsi, I really thought I was buying the best of Audi, but it certainly leaves a lot to be desired. After three months of buying it, I noticed that there was a cadential noise in the engine, and that such cadence increased when accelerating. I was told it was the fuel pump that was failing and, since then, I've already changed 2 fuel pumps, 1 temperature probe, all the injectors and the common rail, but the noise is still there. It has also been checked if it was an electronic failure, but apparently it is not. So the problem is not yet solved and the warranty is about to expire. What else can I do?

It is an ordinary noise the one you are hearing, even more if it is diesel.

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

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?

Hydraulic lifter rattle when 1st starting in the morning or if standin

Audi A4 2002 2ltr petrol avant a4 auto tip 76000 miles
Recently had major service , with so called correct oil, but came back and rattle developed , so put 1/2 pint of magnetic oil in her and then half bottle of noisy hydraulic lifter oil from b & q superstore , could not beleive my eyes when I saw this , so anyway after 2 days , fingers well crossed the nose as disappeared , also I now rev engine when turning car off, just like we used to with old motors, but well this may be contributing to the lifter noise going ! Please god let it come back, also car is running supreme and the engine power as defiantly increased since major service , I have cherished my Audi over the years though , hopefully it will battle on for years to come ! Try this method before large garage repairs and please let me know the outcome.
