I hear a knocking sound for a few seconds from the rear of my 2004 Audi S4 when I turn the key to the on position. It is independent of the engine, this knocking occurs with or without starting the engine. Here is a recording of the sound: [URL] ..... What could be making that noise?
View 5 Replies'01 Audi A6 2.7T, has 97k...I noticed the car making a loud clacking/taping sound at idle that didn't change even when car warmed up. Check engine light came on today...codes P1340 and P0341 both deal with camshaft being "out of sequence" on bank #1.
View 7 RepliesMy 2k Passat has 130k on it. I have done regular oil changes and had the timing belt done 6 months ago. It is in Las vegas right now, as it wouldnt start, and I was informed that it needs a new engine. It ended up starting when the guys at the shop squirted tranny fluid down a plug hole...but has been smoking. I was told this means I have a blown head and the engine would have to be torn apart to check out the bottom half.
I am almost inclined to continue paying to store the car until I pay off the 5k that I still owe on it, just to turn around and junk it...but I feel like maybe that would be rash.
My wife went to use our 2004.5 Passat V6 4Motion and it takes quite a few cranks for the engine to turn over and start. It sounds like the battery is losing it's charge. When running, none of the idiot lights show anything.
I have a couple questions: Could the alternator be damaged and isn't charging the battery or is it possible for the battery to be going after only 4.5 years?
If it's just the battery, how easy is it to replace? I've done them on previous cars, but with all of the electronics and stuff, I'm concerned since it's behind the firewall and I've read stories about it losing all of the electronics. I couldn't see an easy way to remove it, but I didn't spend much time looking.
I got new 2010 golf almost a month ago. And I drove just over 1000k so far. Couple of days ago i noticed that sometimes (very randomly) when i stop some knocking sound starts coming from rear (i think somewhere around passenger side). As i stand at alight and the sound comes on, the sound disappears if i take my foot off the breaks and then appears again if i push the brakes. The sound usually goes away in about a minute. Again, the sound is quite random so I'm not able to reproduce it.
View 6 RepliesThe issue is, when driving at low speeds, especially after coming to a stop, I hear this intermittent knock that comes from the rear of the vehicle. I am not sure if it is coming from the outside or inside, but it really sounds like it is coming from the chassis.
View 13 RepliesI got my HSD HR coilovers and they went on great but its like there's a bumping or knocking sound coming from the rear that wasn't there before? They look great and got me as low as I wanted.
View 6 RepliesI hadn't driven my new GTI (DSG w/PP) for the last month. It was regularly started but not driven. Took it out today and noticed a knocking sound coming from the rear that could be heard every tire revolution. Distinct sound, not metal to metal as if a caliper had hung up. Noise in forward only not reverse. Nothing interfering with tire revolution. Needless I'm not driving until I get it checked out. What it could be?
View 2 RepliesI had to replace 2 tires on my Camry recently and Discount Tire put the new tires in the back and the old tires in the front. After all was done, I drove off and there was a knocking noise coming from the passenger rear.
The front steel wheel was pretty beat up so it was making the steering wheel shake. Discount put that wheel in the back. They had recommended replacing the wheel. I picked up a new one from a pick and pull and its still making the knocking sound.
I went through the car's interior to try and eliminate anything rattling around making the noise. Checked the trunk and there was nothing that I could think it would be.
It knocks at low speeds from 5 mph all the way up to 40 mph. But once I get to 50 and over on the highway the sound goes completely away. The car does not ride rough or shakes when the sound is present.
There is a knocking sound in the rear passenger side area. Cannot diagnose the cause, what it could be. I checked the bushings for the anti sway Bar but that was not it.
View 1 RepliesFor the last year or so i have been annoyed severely by a clunking knocking sound from the rear (possibly passenger side) of the car. The noise occurs when there is torsion occurring or a sudden change of direction. I can go over a huge speed bump or pothole and not hear a thing yet the slightest change in direction or torsion will cause this extremely annoying heavy metal clunking knocking sound. I tightened every suspension system related screw in the rear of the car and the noise is still present.
The car is lowered on H&R springs (approx. 1.4 drop) so im wondering if maybe there is an additional stress that has been torturing the sway bar links for the last 3 years causing this noise. Or could it be the shocks (which are working properly)?
2006 Sonata 2.4 GLS. My car has done 60000 miles and has developed a creaking/knocking (metal on metal clunk) sound at the left rear. it is only noticeable at low speeds when accelerating and decelerating in stop start traffic.
It is not the shock as I have removed the shock and driven the car and the noise is still there, I have also looked at all the bushes and nothing is obvious. I have also checked tightness of all bolts/nuts.
My 98 lumina seems to make a knocking/bouncing sound in the right rear wheel well when I brake. It never happens when I'm braking driving in the city (25 mph or so) but it happens when I'm closer to 40mph and up.
I thought it might've been a drum brake issue but I just had the brakes serviced about two or three weeks ago. It still does it. This isn't a new issue. It's something that's been going on for years.
So I started hearing a knocking sound from the glove box on start ups recently, and now it's happening while driving too. Sounds like the CD player is knocking, but I've never even put a CD in there.
View 6 Replies2005(its NF model) Sonata 2.4 petrol manual. 75000 miles. On cold start makes knocking sound( sound like Diesel). After coupe of minutes when warms up the knocking sound gone.
Also when i start driving( still on cold engine) i hear that sound only when i let go from gas pedal and only in range of 1800-1500 rpm. When i accelerate i don't hear that knocking sound.
I think is not belt tensioner because sound is much longer than couple of sec.
Since I had my 40k service a few months back, I hear a knocking sound for about 3-5 seconds after a cold start (overnight is long enough). It's a pretty loud clicking sound, even worse if the car hasn't been started for a few days.
I brought it to the dealership and they said it's "the sound of the lifters clicking before they get pressurized with oil". They said the oil level is fine. Doesn't seem kosher to me - didn't happen before the 40k service.
Could they have used the wrong oil? Or perhaps didn't put something back together again properly?
I had a toyota prius gen 3 last year where it had an engine knocking sound, where I tried every TSB and changed the spark plugs, spark plug cables, intake manifold, engine knots..... etc., nothing worked except the following video which solved the knocking completely with no return.
View 12 Replies2006 Sonata LX. It's only on a cold start up and lasts for about 30-45 seconds tops..and then it goes away. Car has 74k on it. Treated well. Only use synthetic oil and no check engine lights. Last oil change I put 5w 30 in it. I know it says to use 5w 20. Could this be the problem?
View 17 RepliesI have a 97 7.3 ... I've had it about 2 months now and now it wont start! It will start and idle for 2 seconds then start knocking and die! I had a buzz test ran on it and all is good. I also checked my Icp and checked my uvch harness with my multimeter. Before this it would run ok but seemed like it had a miss and a lack of power. On start up if i didn't have it plugged in it would smoke white smoke horribly. I am thinking maybe my IDM. I need my truck for work .... I had it hooked up to a scanner and it said faulty IDM.
View 1 RepliesJust became the proud owner of a used 2011 F-250 Supercab, 6.2L. Overall the truck is great but it does have a-few things that need fixing, the most annoying of which is a knocking sound from the rear passenger side cab corner. Sounds like the exhaust vibrating and smacking up against the floorboard but that's not it. Everything seems tight, even the front suspension.
The only thing I can see that may be the cause is the rear passenger cab mount seems worn. I can rotate the bottom rubber portion without too much effort and when I feel for the top rubber portion all I feel is the metal cup on the top, like the rubber has collapsed and the metal cup is sitting directly on the frame mount.
So... how many cab mounts there are for the Supercab? I think there are two on each side and two in the front. All of the information & videos I've seen describe the locations for the crew cab. Also, is it possible to replace the cab mounts and not have to mess with the ones in the front? I hear those are the real buggers.
I have a knocking sound from my D4EB engine (2008 Santa Fe. 120,000 miles)
Problem has been any diagnosis of the cause because the mechanics cannot agree. One has said top end and another bottom end. If it is top end when I think the consensus would be to get the present engine rebuilt. However, if bottom end then, because of the increased cost, the better option might be to replace with a reconditioned engine.
