Golf GTI 1.8t knocking or tapping noise.

Hi, that would be awesome if your sure that you don't mind. I'll give you a call about 9 tomorrow morning just to confirm.

Snail, its possible mate but I honestly have no idea at this stage.

Thanks.

I could probably look earlier in the day if that would help. I said 12 because I am doing some VCDS coding for a couple of others then.

10 would be ok I reckon. Call me Sunday if that will work for you.

I'm betting on cam chain tensioner.

im im going to second this. Had it happen to my old GTi where this broke and by some miracle, the belt stayed on but it made an awfully loud ticking/knocking sound, like you were winding something up.

i would not drive and have it towed to your mechanic just to be on the safe side...

There are 2 things being talked about now, the cam BELT tensioner and the cam CHAIN tensioner. Very different things at opposite ends of the engine.

Either failing could be nasty but I don't think speculating on the internet will diagnose it well.

Hi Guys,

just wanted to provide some new info to see if it gives anyone an idea.

The last few days the car hasnt been making the knocking noise and I was scratching my head as to why it had stopped.

I've realised that when the climate control is completely off, so that it actually says off on the screen, the solenoid I was talking about never activates and as a result the knocking noise never happens. Keep in mind that when it does happen it only does it for 30 seconds after starting the car or when driving up my steep driveway, slowly in 1st gear.

Is there a fan on the aircon compressor or something that could be loose and hitting something?

Thanks again for all the help.

With the aircon running the radiator fans run to pull air through the condenser. Could easily be something in there that's touching? Or maybe the compressor or poly v belt/tensioner. So hard to say without seeing it first hand.

Ok, thanks Gavin. So its not something that urgently needs to be fixed before drivng the car again?

I'll take it back to the mechanic and see if it makes the noise this time haha.

Thanks heaps for all your help mate.

I just saw this post, not sure how I missed it last week. Thanks mate. Also, not sure if you got my text but I think I found the source of why my car wasnt registering as much boost as expected. BIG air leak.

In the UK mate, not had my SIM in as I haven't set up international roaming. Back on the 19th. Hopefully you have nailed it though.
