As the title says, there is a loud harsh banging/rattling sound when hard accelerating in 1st and 2nd gear, then goes away straight away. There is no noise when normally driving. It sounds like its coming from the front passenger side and actually sounds like its from the cabin. It also does it more when turning right. Used to only make the sound in 1st from stand still when very hard accellerating, I just thought it was my dodgy clutch control that used to make it happen lol

Anyone have a clue? read through other threads and suggest drop links but how can I tell its them?

drop links are more of a 'rattle' than a bang. but you can check them by taking your wheel off and checking for play


I'm sure your well aware what you looking for but;

Check your gearbox mount maybe?

Thanks for both your replys, I will check the drop links and try and see what condition the gearbox mount is. For the drop links I thought it would make the sound going over bumps and uneven road which it doesn't.

My Mjets banging like a porn star. Exactly same as yours. I'm going to check the gearbox mount too.

Lol chris, I get this feeling it might be the bar that goes across the exhaust to stop the undertray hitting it. But it sounds like its coming from behind the dash.

Mine does this, I just tell the bitch to shut up and carry on driving.

It seems to have stopped now :S maybe it was something behind the dash.

It came back again this morning then went away this afternoon, I don't know if its stopping when the weather is hot or just coincidence.

try looking under the bonnet on the drivers side. I had a loose airbox mount. Rattled exactly same as yours, except I don't know the layout on a tjet.

M-jet exhausts have been known to knock on the bracing bar, I imagine t-jets could suffer the same problem.

Thanks but its not from that side but I did check it before just incase the sound was travelling through the car.

I'm defiantly going to check there, just need to get it on stands first and get the undertray off.

Update!!!

Think I found 99.9% what the sound is, The bolt that holds the downpipe from the turbo to the cat heatshield has fallen out and I think the pipe (because its not secured) is hitting something underneath. I did try and fix it at the weekend but it was impossible to get the pipe bracket hole in line with the heatshield, even doing it with the undertray off the car which I don't know why

I had the exact same issue sorted this week after 2 months of rattling, check your dipstick and make sure it doesn't rattle in it's place. Have the rubber handle pointing north / south of the car (facing the cabin) and see if that helps. This was my issue and would only be present under hard acceleration and turning sometimes due to the engine workin harder - biggest relief and cheapest fix ever.

PS: Also make sure oil isn't low, mine was too.

Thanks for that but it must be this pipe because the dipstick and oil level are fine. Cheers anway

Re: Update!!!

Maybe a coincidence but I think I too now have a worn gearbox mount, as its making a fairly loud/solid thud occasionally on hard acceleration/breaking. I don't think its a pipe sound but something else for me to check.

I have a powerflex mount ready to go into it anyway so I think I'll just replace the whole thing while I'm under there, it is coming up to 5 years old and the rubber down there is open to the elements so I wouldn't be surprised if its becoming perished.

Gearbox mount is fine and the droplinks are alright as well. Didn't realise powerflew did a new mount for the t-jet.

Re: Update!!!

Its not a whole mount just an insert that drops into/around the rubber in the mount.

Have you got a link to this please as I can't find one anywhere.

Still have this annoying sound I've checked just about everything from the intercooler to the headlight screws and bolted and downpipe to the heat shield so fed up with it now, I might have to get the drop links done and see if its them which it probably isn't.
