Hope you can help, the first issue is:

1. A strange noise coming from my front right brake when breaking, doesn't happen when im stood still and pump the brakes, the best way to describe the sound is like a ratchet getting tighter the harder i push the pedal.

2. A clunking/knocking noise only when i go over large bumps or potholes,

Replaced my phone recently and now I can connect via Bluetooth but I'm unable to control the phone via Bluetooth nor am I able to access the address book.

The mrs phone works perfectly fine (this one did as well when it was her's. I get the car she gets the new phone)

Anyway phone in question is a Xperia Z her's is a Xperia Z1. The phone connects fine but when you try and dial a number the car shows dialling failed. Accessing the phone book it just says it is not available.

Hi guys, two things that have started happening so hoping someone has experienced them.
Firstly, on first start (so cold) while accelerating car sounds like screaming when you would normally hear a whistling. Goes after 10 secs or so and only on first start up.
Hoping maybe a small hole in boost pipe and not the turbo starting to fail!
Also got the "Turkey gobbling" noise back maybe connected?

Second I noticed at mcdonalds drive thru. Window down to pay and pressing brake pedal can hear a noise

I have been trying to find out what horn my J has as it kind of stopped working properly recently, all I get from it is a faint meep.
I think it went due to water damage :(
I can't see through the grill or under the bonnet as to whether I have a single or dual tone horn.
Anyway I have been hunting high and low for info to help me choose the correct horn to fit and I keep seeing conflicting stories on which is correct.
My car is a 2010 60 plate 1.6 SRi.
Does anyone have any pointers as to w

Does anybody know why my USB/AUX port would not work?

I first tried plugging in a small USB hard drive (always worked with my old head units) and now I've tried a 16gb SanDisk Cruzer Force (just with 4 MP3 albums on it) and it always says something like 'no aux devices detected'

It's a CD400 head unit and the car is only 1 year old......and its super annoying

Hi All

Always felt my GTC 6spd box was a bit notchy 1st-2nd, well yesterday it finally became a more serious issue and now the car will not hold in 2nd under any load it just wants to jump back into neutral so nursed it home doing 1st - 3rd changes and dumped it on the drive.

I've built gearboxes before but not for anything Vauxhall - I have seen pics of gearboxes rebuilt in situ by removing the wheel, arch and casing to reveal gear clusters but I think that was an earlier astra possibly w

This morning I went to start the car as usual but all I got was a click tried a few more times and eventually it started however I had no lights on my radio even when lights were switched on I pressed the radio button and all was fine!I have changed the battery and starter motor last year as was having problems.but this is out of the blue?!

Hello. I'm driving 2011 Astra j with bi-xenon lights and auto control of the lights. Sometimes even in bright sunny day the lights still remains on and the HUD display stays in night mode. Have found that most of the J's have this issue and didnt bother so much. But lately the things became stranger. The HUD display switches to day mode but the lights remain on.

Right I'll try to describe as best as I can. 

Got an astra 1.6 petrol (5 speed box). Hate the car but hey ho.

Noticed a noise a week or so ago, it almost sounds like it's whistling slightly as I was going up through the revs, mainly around 2/3k.
