mkoneman Posted March 15, 2007 Report Share Posted March 15, 2007 car: 97 audi a8 4.2 auto tiptronic 130,000 miles on the clock i started the a8 up this moring (after driving it hard last night) and there is a rather strange noise coming from the back of the engine bay(near the bulkhead) a whining noise that changes with engine speed, has anyone had this noise before? im sure its not the engine could it be powersteering rack or he torque converter in the gear box? it make the noise in gear out of gear on the move or stood still anyone?

Ska Posted March 15, 2007 Report Share Posted March 15, 2007 Did it go away after warm up? Did it get worse when turning the steering side to side? Proly the power steering needs flushing as per Audipages.com your fluid should be green and not black Link to comment Share on other sites More sharing options...

Atomic Posted March 15, 2007 Report Share Posted March 15, 2007 And it's not the interior fan? They've got a habbit of going noisy and could easily vary with the engine as the alternator raises the voltage. Check here to see if it's the same place: http://www.audipages.com/Tech_Articles/heatac/fanreplace.html Link to comment Share on other sites More sharing options...
Ska Posted March 15, 2007 Report Share Posted March 15, 2007 If its the fan turn off the CC and start your engine and listen Link to comment Share on other sites More sharing options...

mkoneman Posted March 15, 2007 Author Report Share Posted March 15, 2007 ill whip off the covers tomorrow and have a look if the gearbox oil was low would that make it make a noise? Link to comment Share on other sites More sharing options...
Ska Posted March 16, 2007 Report Share Posted March 16, 2007 The gear box oil pump makes a sort of echoy screaching noise when cavitating and can be heard loudest from the n/s wheel well, with the bonnet down. It doesn't hurt to check the oil level though but I don't know where the oil would go unless it had a leak somewhere. Link to comment Share on other sites More sharing options...

S4_Dan Posted March 18, 2007 Report Share Posted March 18, 2007 mkoneman, the noise from your car, was it like a 'whirring' niose that was consistant with the engine revs whilst stationary and whilst driving? Is the gear box oil pump easy to access under the car and is it obvious to spot the pump or is it internal? My car has had a whirring noise ever since i purchased it about 5 weeks ago now. i put it down to a tensioner making the noise, but feel i could be wrong and this is more serious! What other gbox (if any) problems occured since this noise? Cheers, Dan Link to comment Share on other sites More sharing options...

Cheers, Dan [/ QUOTE ] yes it was a whirring noise the noise is constant with engine speed moving or stood still the pump itself is not accessible without a gearbox rebuild the 1st thing to do is change the oil filter in the box £130ish for all the bits from Audi it started as a hydraulic bleeding noise on start up then one morning didn't go away!! only drove it 5 miles to work where i could get it over the pit to do the work i took the sump off yesterday and left it draining all weekend then ill put it back together next week and let you know how i get on the easiest way to find out if its the box as it dose echo around a lot is to try and get under the car and then it will come blindingly obvious where the noise is coming from HTH Link to comment Share on other sites More sharing options...
Ska Posted March 18, 2007 Report Share Posted March 18, 2007 try and find out jow much of the ATF drains out over the weekend mkoneman It'll be interesting to see if you get all the 8 litres out, remember only to use the Audi ATF I'm gonna do a nother Gbox ATF service soon but I also want the fuid in the pipes leading to the oil cooler drained so as to do a complete flush if there is such a thing Link to comment Share on other sites More sharing options...

Ska Posted March 18, 2007 Report Share Posted March 18, 2007 Your right at £7.46 a litre its is a bit expensive but if your not flushing the system completely then your just diluting what ever metal filings and crap is left over Link to comment Share on other sites More sharing options...

S4_Dan Posted March 18, 2007 Report Share Posted March 18, 2007 was it an easy process to do? did you remove the exhausts or leave them in situ and work around them? Looks like ive got mine to do! plus an engine oil change as sounds a bit tappety on start up (as per other post currently in forum) Keeps us all posted. Can you post part numbers for the new parts and what year is your nice looking A8? Love the colour and lowered suspension! Dan Link to comment Share on other sites More sharing options...

S4_Dan Posted March 18, 2007 Report Share Posted March 18, 2007 does look well! Got my A8 (as per sig) 5 weeks ago. Needs a good clean inside but i don't think i'll be goin quite as far as you! . Same colour, Ming Blue with ecrue leccy recaros. (best combo imo) Rear sun blind worked 5 times then stopped! so will need to sort that out. Nice low mileage example i got, just the box is the let down i think. Will look forward to hearing how you get on. ive taken mine off the road today from now on!
