knock knock knockin on audi's door

[johnyj]

put my car in for a full service and asked them 2 investigate a knocking.
passenger side rear.
every time you turn left there is a knocking noise
as you straighten up it stops.
garage said its the rear shocks
they are monroe shocks about 1 year old
anyone think it is the shocks?

 

[Broken Byzan]

Could be,is it a quattro ? or FWD?

I blew a set of sensatracs in 14mnths

 

[johnyj]

its fwd maybe it is the shocks then thought they lasted abit longer
there monroe ones i think sporttrack or something

 

[Danielson]

i replaced my shocks at 80k ish and they are still fine at 102k, my nearside rear used to knock, it was leaking like a goodun, easy to spot.

 

[johnyj]

ill have a look
i also asked him 2 look at the turbo 2 check condition.
he says the turbo is not giving alot of output normaly 10psi
says its weird as theres no noise coming from it 2 suggest any bearings goin.
any ideas?

Wastegate acutator ?

Mine lost its preload and would not keep the wastegate shut so the turbo was not making any boost

 

[johnyj]

cheers phil its goin back in on fri so ill tell him 2 have a look

 

[PhilR]

Yeah...you can just about squeeze your hand in to the actuator rod, mine was slopping back and forth hence not spooling the turbo ( no whistle noise), interestingly the car made 136 brake on jabbas rollers with this problem (was running 0.1 bar of boost ~1.5psi !!), i bet theres loads of a4s running around with the same problem as i had unknowingly, i know of another 2 that have had the same failure, forge sell replacement actuators for 70 quid

 

[Beerzo]

Would this actuator fault show on VAG-COM?

 

[PhilR]

would only show on VAG COM if you log the requested boost against actual on a live run, not sure which controller number you need to monitor though

It will not show as a fault, i only found out about mine when jabba did the power run.

 

[Sayre]

Im guessing a CV Joint

 

[johnyj]

pretty good at 136 bhp with no turbo.
the more you talk about it it sounds like mine i cant seem to hear any spooling of the turbo either.
hope it is this so i can unleash the beast when its fixed(rubs hands)
any difference from standard to forge?
he also said about oil goin somewhere there was only 1 litre left when he drained it.

 

[PhilR]

The main difference between forge and standard is that you can buy a forge one, audi and all the other borg warner dealers will only sell a complete turbo unit no seperate actuator,the forge one is slightly uprated and ideally suited to a remap, loss of oil could mean a more serious tubo problem oil seals etc, you should take the inlet hose off and check for a bent (unmovable) shaft
