have i broke my gearbox?

I am amazed (and impressed) at what people can hear from audio clips - I couldn't hear anything because of the passing Tractor.
On a serious note though, years ago, I had a business motor insurance policy that covered hiring another car if the main car broke down away from home and could not be driven.
It worked a bit like the extra insurance we often take out when driving abroad.
The strange thing was there was no time period on the hire. I never used the provision
May be worth speaking to the insurance company or your broker
 
i'm in swimbo's lean-green-death-machine (p reg pug 106).

so the garage recons its the flywheel due to the low vibration and noise.

Hitting the wrong gear shouldn't really do that much damage internally as in theory the forces involved should slip the clutch. But right up to the point where the clutch slips everything is torqued right up, my FMEA head makes me want to look to the engine/gearbox mounts as first point of call. If its not something as simple as this then I would probably keep driving it until the problem showed up, just keep an eye on fluids and temperatures.
A friend of mine once had a rental that he abused for a day, he wanted to see what would happen if he put it in 1st at 70ish... clutch slipped and engine bounced off limiter for a few seconds until revs dropped enough for the limiter to release. We were both expecting something catastrophic, but I guess the designers really have thought of everything.

It really doesnt happen like that, the rev limiter is irelevant when a gear to low for the road speed is selected and the engine can be forced right through the redline regardless of any revlimiter as its being forced round by the wheels-if the clutch slips to avoid this scenerio then its purely luck & not by design.

Ive not heard the clip (at work) but id guess at an Engine mount - you'll have certainly put a LOT of stress on it from 6th-2nd. After that it could be anything, including the good old brake reaction (lollipop) bushes

If you think you have a noisy pulley, try a quick squirt of grease on it - just be sure to miss the belt itself!

Agree here in that there does seem to be a bit of confusion. If you manage to select too low a gear, in the instant you engage you may get minor slippage from the clutch or even a yelp from the tyres, but in a fraction of a second once tyres are gripping, clutch biting and all mounts tightened up, then the engine just spins up to whatever speed the gearbox demands for the selected road speed and ratio. If the engine cannot handle it then it breaks a weak point, be that valves, pistons, rods, etc. or breaks ancills such as water pumps, aircon, belt pulleys, etc.

If you declutch then the engine slows pretty quick but rev limiters, etc. are irrelevant. They are for accelerating up.

Separately during the enormous torque going through the system you can destroy dual mass flywheel, prop joints or tear bushes apart. Whatever is a little weak or tired.

You may well have more than one i.e. screetches could be a damaged ancill. or pulley (or engine internal) and knocks something physical like a damages bush now allowing something to touch such as exhaust or engine onto the mount point.
 
i get what smart bear means. anyway its getting a new clutch and flywheel and is a costly example of what can go wrong lets see from there if anything else is goosed. hopefully not for my wallets sake. :D they didn't think anything else was wrong. once up in the air and they could get upclose and personal the noise was obvioulsy coming from the bell housing.

so i can write a good how-to on destroying a dual mass flywheel if anyone is interested :D shame it wasnt something simple like a snapped manifold as it would have been a good excuse to get a new fancy one :D



interestingly the garage also reported the vacuum hose from the servo to a T under the inlet had collapsed so thats getting replaced too.
 
yes, new one and new clutch on order to be fitted thursday. i ought to get them to remove that bloody valve jobbie while they are down there.... im sure ive slipped my clutch loads due to it.

That sounds like best part of £1k bill :thumbsdown:

Had one fitted under warranty on my daughters 1 series and it was a £400 part. Add clutch and 3-4 hours of labour and there you go.
Hope they do better than the garage that fitted mine that didn't realise there are 2 settings and having completed the job had to strip the box out and start again...
 
yes £1100.

from ECP the combo was ~£620 all in so 500 for their labor is ok i guess. they are a respected garage near me. they also picked up on the brake servo pipe being collapsed during their inspection so a new one is going on there too.

its price i pay for being a pillock and using the wrong gear.... anooying but what can you do. chuffin shitty 320d c**t that cut me up oh well. it'll go on a credit card so i can pay it off over a couple of months and means i wont be able to do a few nice upgrades on the westy :thumbsdown:
 
Hurts but s**t happens. You could have been hit.

An arse cut me up on Sunday when in my XF then brake tested me she flashed for so doing. Nice when I had the family in, but my fault if I'd rear ended him :(

I am not familiar with the workings of the DMS flywheel,what are the 2 settings mentioned.
 
In fairness I should have been clearer and it was to do with the thrust bearing which went in at the same time and new DMF. Not being at home I cannot track down what it was.

yeah exactly and the garage is a decent garage so the job will be done well.
