RS4 B7 engine bearing whine - help!!
RS4 B7 engine bearing whine - help!!
Hi there. My B7 4.2L V8 has developed an engine bearing noise it's progressively become louder over the last few weeks. I get it between idle and 1800rpm, even when stationary. Turning the A/C off, rocking the steering, or depressing the clutch makes no difference. When I'm in 2nd or 3rd I can feel the vibration through the pedals and steering wheel, especially coming down on overrun below 1800rpm. I've run it up on a ramp without the serpentine belt- still the same! So it's not alternator or tensioner, ( which is exactly what it sounds like). I've got a fellow mechanic to hold the revs at 1500 and listened with a long screwdriver to my ear, to the water pump, power steering pump and as best as possible to the A/C compressor (it's buried, and difficult to get at). It does not seem to be any of these. However I noticed that the resonance and vibration could be felt (quite violently) coming from both oil cooler pipes coming out of the engine to the front oil cooler mounted at the radiator.
This leads me to think that the noise is being generated from the Gear Plate/ Gear Module associated with the auxiliary drive chain. This is what drives all the external pumps- a/c, water, p/s. It also drives the oil pump which I believe has a gear driven counterbalance shaft within it.
Has anyone else had problems with the Gear Plate or oil pump on a B7

So...I guess the only way forward is to have the engine out and strip off the end covers to inspect the chains and guides to get to the auxiliary gear drive plate....
My problem is that I need someone who has had experience with rs4 v8 engines that I can trust.
Have any of you got suggestions who can take on this kind of job?
My searches on line give me MRC, and Audivwsc in north London. I've used Regal Autosport in Southampton who carried out my full de-carbon and de- flap. Great guys.
I'm just hoping to hear from someone who can reassure me that I can trust my car to a garage that knows what they are doing?

Thanks MB2
I'll check them out
I'm in Beckenham south London, but I want to find someone who knows what theyre doing.
I've seen videos of JHM in the USA, showing complete chain and guide replacements, they know their stuff , but I can't find anyone that know!edge able in the uk.

Re: RS4 B7 engine bearing whine - help!!
does your car have a forge oil cooler kit installed?
Re: RS4 B7 engine bearing whine - help!!
Hi RS user
No it doesn't, ive heard they can cause a vibration.
Ive had mine a little under 2 years, and the only mod Ive had done was a year ago, that was a full de- carbon with manifold off and polymer bead blast, and flaps removed with a de- flap remap, oil change etc. It was done by Regal Autosport in Southampton, i can't praise them enough. Brought my rolling road HP up from 364 to just over 400...not bad for a car with 128k on it.
So this noise has developed on its own...

Thanks cherub 72,
Ive been hoping someone would give me feed back about them.
I saw their website and it looked impressive ( but websites don't always tell the whole story) so I emailed them a detailed description of the problem. But it took them several days to reply, but it was very evasive. So I I emailed again asking for a little more info,, thinking perhaps they are busy and I would give them another opportunity to convince me of their knowledge, that was 19th February...they have still not replied.
Do you just use them for basic service stuff or are they up to speed with more involved technical jobs too?

rsfourby4 - so far they have done all the servicing for the last 7 years. They have also done all the suspension control arms, the clutch, shocks, all the DRC pipes ( whichh involved the fuel tank and rear axle coming out ), accident damage repairs caused when a wall fell on the car, door locks, rear springs and a load of other stuff. I don't like to think how much that lot comes to !
Give them a call and speak to Pitor, he's the more customer facing part of the business and also an RS4 owner last time I spoke to him.

I can thoroughly recommend CamSpec in Crawley, not too far from you - http://camspeconline.com/ - they know their Audis inside & out.
Failing that a trip to MRC might be in order - http://www.mrctuning.com/

Re: RS4 B7 engine bearing whine - help!!
Did you get to the bottom of this in the end?
Re: RS4 B7 engine bearing whine - help!!
Just reading your post and from what your describing sounds like the same noise as mine.
If I didn’t know any better i would say that the fluid is low
In the powersteering (its not) sounds like a whine !
Its had this noise since I bought the car so can put it down to anything in particular that’s happened to it or caused it
