I have recently become the proud owner of a 2003 A4 B6 2.0FSI after spending 3 years with my beloved Subaru Impreza WRX.
I loved my Subaru but its drink problem became unbearable so it had to go. I have always liked Audi's since my dad used to have an Audi 80 back in the early 90's so getting an A4 wasnt really a difficult decision to make. I contemplated getting a diesel A4 due to its fuel efficiency and high torque levels but being a petrolhead i decided that the 2.0 FSI was really the best option for me.
As soon as i found a nice looking FSI within my budget i snapped it up and i have been buying little bits for it ever since. It has also had fresh oil, filters and spark plugs straight away just to make sure it runs as smooth as possible.
One thing i have recently noticed is a humming sound coming from the engine compartment i think. Its really difficult to pin point exactly where its coming from as it is only noticeable above 40 miles/hour. I am not a mechanic but i dont think its connected to the drive shaft or gear box as its present even when the car is rolling with no gear engaged. Its not a rattling or mechanical type noise (wheel bearing for example), its like the noise a fan would make at start up and it seems to increase as spead increases and decrease as speed decreases. I have noticed that my aircon is not really cool - probably needs recharging - but dont know if thats somehow connected to this noise. Obviously the noise is present when aircon, radio etc are off. I also thought it might be tyre noise as the previous owner had winter tyres on the car but to be honest its too loud to be tyre noise i think - i have since increased the tyre pressure a little bit but there was no difference.
There is an aftermarket cone-type air filter on the car which just makes it sound a bit throatier during acceleration but im sure it doesnt contribute to this sound im trying to describe as it can be heard regardless of me having my foot on the throttle or not.I may be exaggerating a bit but it sounds like a plane about to take off! Has anyone encountered a similar thing? Any advise would be appreciated.
Another niggly thing is the radio reception - pretty bad. I have read a number of threads on here regarding this common fault of the aerial booster situated above the back windscreen but i have not really read about a solution yet - unless you want to pay Audi hundreds of pounds for a new part. Could anybody point me to the right direction please?
Also has anyone had to change the light bulb in the glove compartment? It may sound a bit silly but there doesnt seem to be enough room to get your hands in and get the plastic cover off without forcing it and breaking it! Any advice?
Apart from all the above, the car is great! Definite improvement on fuel and insurance bills compared to the Subaru and of course a lot comfier too (i think i might be getting a bit old). Performance is not comparable really but i ve had 3 good years in the Scooby and to be fair driving the Audi is not as risky in terms of losing my licence.
I have tried to attach a couple of photos of the new and the old but failed - maybe im not allowed being new in the forum etc. I
hope someone can advise about those issues stated above.
