Knocking noise from front right of engine bay. Holden say its the ABS. Need help.
I've got a 2009 VE Commodore SS and have been hearing a knocking noise in the front right side of the engine bay for the last 10 months. Almost every time the car has been stationary for a period, I'll hear the knocking once the speed reaches 15kms/hr.
I've taken the car back to Holden several times and they have not been able to find the problem.
The latest from Holden is that it's a normal sound in the car however they cannot show me any other car with the same sort of knocking sound. Holden are trying to tell me that this is the sound of the ABS calibrating or some sort of self check. I don't accept that this is the problem as it didn't happen from the day I took the car home, it only started 14 months later.
Has anyone had this problem or heard of it before? Or can someone suggest where to go from here as Holden are unwilling to take the this matter further.
Thanks
Mines the same after I start the car when I reach 13km/h a view ticking/knocking noises I just ignore it as I have read here that this is the abs calibrating it's self and is normal
+1. Have the same thing after first start and reaching approx. 15km/h
Have been told by a number of places that it is the ABS going through its self test.
Mine doesn't make that noise when first driving off. Although mine is an 07 I have driven some MY09 and 10's and haven't heard it.
my 2010 sv6 does it too
sounds like abs check and nothing more
+1 for the ABS self testing, mine is a 2007 sv6 and it has done it since new, although you may not hear it at all if you have the windows up and/or the radio on. There are many threads about clunks and noises from the right hand fron on hear in which this accounts for most of them.
There is a thread about this already.
My 07 SS does this, along with everyone else's VE. It is the ABS self test. Mine kicks in at 13kmh.
Might have to get my ABS system checked.... Definately no clunking sound on first drive off
The OTP stated that the noise was not there earlier so it could be something out of the norm!
I'm not certain that the engine bay clunk you hear is the ABS totally. You can normally feel the ABS self test sequence through your brake pedal or even hear it as a slight buzzing noise.
The clunk in the engine bay area (mine clunks twice at about 28 K's) is possibly the EBD or the ESP doing its self check. What ever it is, its an unacceptable noise for today's build technology. Get with it Holden/Bosch/Hyundai
Maybe its how the unit is mounted in the bay. Maybe it could be isolated/insulated a little better to reduce the clunk. As for Holden not pursuing any further, I would go to another dealer that cares about service

I've got a 2011 VE2 SS Ute and mine cluncks twice too. Once around 15km/h (usually when the auto is upshifting from 1-2) and then around 28km/h which is usually when the auto is upshifting from 2-3. Only ever happens on start up when first taking off. As it happens every single time and always at the same speeds I just thought it wa normal...and still do.
Yer it probably is normal but you shouldn't be able to hear it. The Bosch ESP 8 system is used in many brands of cars and is considered to be the best when released in 2001. EG: if you jump in an 2009/10/11 Audi you don't hear a "clunk, clunk" everytime you drive off after starting.Originally Posted by bluessv
When I drive off after starting I get a buzz from the ABS at about 15 K's and then a double clunk at 28 K's. The clunk can vary in volume...
I am a little familiar with the components of the ESP 8 system but I'm still investigating exactly which component is producing the noise. Of course I will advise.

I have been going insane with the knocking sound in front RH side of my MY09 VE 60th, it only happens when the car is cold and turning right taking off, and only just for a few moments. Apparently the Holden Service Manager took my car home so he could listen for it off a cold start, only to find out he can't hear the knocking... and looked at me like I was just a stupid woman when arguing the point.. $1400 later and driving out of the service department and I hear the knocking!! I have had the engine mounts replaced and apparently there is nothing wrong with the suspension. They tried to tell me it could be a sound off the tyres... if so wouldnt the same noise be made turning full lock left on take off?? Its extremely frustrating as whenever I have someone else in the car it doesn't happen or it is so slight that they don't notice it... but I can.. Any ideas on what it could be?

My 2011 SV6 does it as well. 2 knocks and that's it. Doesn't really bother me
My august 2010 build SV6 does it also , mentioned it to the dealership & told it was the abs running thru a self test , so it is either correct or Holden have told the dealers to feed this to everyone who asks just to shut them up , I'm not sure of his name but i recall we had a Holden technician in the forum , maybe he can shed some light .
Yer any unexplained noise sends me into detective mode. I'm not sure exactly what your noise would be but its in the same vicinty as the ABS/ESP self-test cluck-clunk!
Since you say that it only appears when the engine is cold is puzzling. If your noise is two consecutive knocks (clunks) that sound directly in front of the driver around the engine bay area then is a normal ( well VE normal ) noise, however, the ABS/ESP self-test is reset when ever the car is turned off. Meaning you should hear the two clunks everytime you restart and take-off. It normally performs the self-test at around 20-30Kmh.
In my car the clunk-clunk volume does vary (or maybe the radio is too loud) and I sometime don't notice at every re-start.
If your dealer has checked your suspension then the only other thing is that RHF shock is faulty and giving some noise when cold...

Holden design noises like this into the car in order that when the real problems start, they are disguised as "normal".
Nothing unusual, move along.
Thanks guys, I guess ill just learn to live with it LOL
