just picked up a a4 52 plate just noticed the recectiom is terible any ideas on this as theres no ariel so take it its buitl in some where

 

cheers lee

 not sure about the a4 lee, but its probably in the window screen, can you see any lines round the out side of the screen, if so its the ariel

 ok cheers will have a look in a bit

Saloon, Avant or Cab?

 sorry m8 its a saloon

That's ok.  At the back of the roof trim, there's a 5" wide strip that just pops off - it will reveal some connectors.  Ignition off - check they're all connected and clean etc.

A common problem is... I can't remember, but it's the 'aerial amplifier' or something like that.  Sorry I can't be more specific!

Oh, and check that the connections to the window are ok too!

 cheers bud will have a look tomomorow

 

 any luck yet leeroy?

 didnt get a chance to look yesterday every thing went a bit petetong

hopefully get out there today and have a look

will let u knoe tho

 

lee

 had a look yesterday checked all the wires under that panel all seemed clean dry and good condition

any think else to look for u can think of

 

lee

Does your heated rear window work?

 not sure m8 havent had to use it yet lol i sopose if its just got water layin on outside and turn it on i should notice if it works goin out in min so il try it

 just poped up to b&q left rear windscreen heater on on the way up mirrors were warm to touch as was the rear window so guess its working

It's worth plugging it in to vcds (a diagnostic tool) to check the radio.  I suspect that the aerial amplifier is buggered though.  I can't help any more than that I'm afraid as it hasn't happened to me, I'm just going on what some other saloon drivers have experienced!

 cheers for your help  bud will vagcom work on the audis

 Yep all versions of vagcom will work on a 2002 A4

Either open the program and click Auto Scan and choose 8E B6/B7 from the drop down box, or open the program, click Select, click 56-Radio, then Fault Codes.

Then go here and find the code as it's quite useful.

 cheers will try and get it on tomorow if im back from my course in time will let u know what i find

Cool, I think it's worth doing the Auto Scan as it checks the whole car - make sure the ignition is on & don't be surprised when a big red brake symbol appears on the dash, accompanied by beeps... it's normal!

 lol cheers i have used it on my old mk4 so sort of got a clue lol but yer will do whole scan clear codes then do it again in a day or so just about to do it now as it goes

lee

 well that wasnt so good lol heres what i found

engine start blocked by imm   17978

key signal to low 01176

actuating motor for temp flap left blocked or not working 01809

hi pressure sensor (g45) 00819

internal control module memory error 65535

alarm trigigger internal 01370

alarm trigger due to tilt 01369

rear right door 01562

rear right door wont de safe 01562

so not good internal controll module what is it were is

take it the flap is well hidden behind the dash as i can hear somethink constantly moving

high pressure sensor take it thats y the aircon dont work also were it this sensor located

if u want to give me some solutions to all these faults would be great

also i tried to clear it said it had cleared the faults but they came up straight away again

 

lee

Try going into each controller separately and deleting the codes.  I find that when I choose 'Clear Codes' from the auto scan, nothing is deleted.

Alarm triggered - don't worry

Positioning motors - don't worry unless you're getting differing temperatures from the left/right vents

Doors - clear and see if they come back, my driver's door does it once in a blue moon.  Maybe check the door wiring in the rubber gromet ting near the hinge.

Engine start blocked - obviously no problem now.

Key signal - low battery in remote, change it.  Recode key (if needed) by unlocking car with key, put key in ignition, turn ignition on, hold unlock on remote for 5sec, ignition off, door closed and click lock on remote... always works for me.

High pressure sensor - heard about that, but no idea about it, sorry.

Internal control module - Not sure what module this is, what section of vagcom was it in?  Is the part number 8E0 907 279 X? (X could be B,C,D,E or F)  If so, do all your electrics work ok?  Does your car have bulb warnings on the display?

the module is in adress 37 ,controller, component :bns 4.2 ho5 bno 0008 if that helps at all

 

i will plug in again tom and do as u said clear the codes in each section

cheers for the info so far lee

It's your sat nav that's causing that fault code then, but I have no idea how to sort it.  I would say go into address 37, click coding, and wait for vagcom to come up with the little bubble telling you which numbers you need, you know, it might say 1= DIS active, 0= DIS inactive - that kind of thing.  Make sure that it's coded properly and remove the fault code.

 that sounds a little complicated lol if its only the satnav il live with it lol as that seems to work fine to

still none the wiser on the radio tho lol

It's really not that hard or complicated, give it a go... at least click onto the screen so you can see what I mean.  The only fault in the radio is that dodgy coding, so fixing that may fix the reception issue.  IF not, my money would be on the aerial amplifier - but not seeing the car, I can't say for sure!

 ok il have a look tommorow

once it comes up with code what do i do was just reading thru rosstech website but couldnt find any think

Just go into 37 Radio and click Coding. Wait 5 seconds and a speech bubble will pop up with how to change your code and what you should change it to. Your code will depend on what features your car has. Write down the original code that is displayed, just in case you need to put it back. Let me know bow you get on, it's a pretty simple thing to do (though I would say that, I've done it loads of times!) Good luck!

 got rid of all codes except

high pressure sensor and the control module so not to bad

cheers again for the advice

just need to find this pressure sensor now and get it replaced

Here's a vague thread about the pressure switch... http://forums.audiworld.com/showthread.php?p=2045927

And maybe recoding the sat nav will fix the reception issues, but I have no experience with sat nav.  Pop into a local vw/audi specialist and see what they say.

Glad all the others went - re-scan in a month and see what comes back.  I'd bet money on the doors!

 cheers benjie i did have a go at recoding the radio but made no difference so put back to original

i tried satnav to but it didnt give me the option to recode i tried out the sat nav lastnight poped to the shop and turned it on on the way home all seems to work ok so i think il forget about that one lol

Happy to help.  Just the radio reception now :-)

Has anyone else found that if you turn the heated rear window the radio reception gets really bad, or is this just me? 

Re the rear window demister, i have found that having this on effects the radio signal drastically. I was wondering if an earth may have come loose behind the stereo.

 

I cant get my aircon to switch on as the econ light wont go off. Does it just need a re gas or is there a more underlying problem???

 

 

 re the aircon. Its quite normal for the aircon compressor to go into a 'safe mode' and turn off when the temperature drops below about 3-4 degrees so it doesnt damage itself.  If its off all the time it would suggest that its running low on gas.

 

Hope that helps, Matt
