Bucking Broncho 16V

Recommended Posts

Bit of a problem - thought it was sorted too, but its back. Basically every time i try to pull away from the lights slowly ('slowly'...it happens!!!!), the engine seems to want to escape the confines of the engine bay, and tries to launch itself into orbit. I have already replaced the front engine mount (which was really knackered when i removed it!!) which helped alot. but its gotten worse again. Though sometimes nothing happens and it all behaves well.

Mechanic thinks its engine mounts. But I want to be able to prompt him to check everything instead of changing all the mounts and it still being a problem.

So I was thinking, would the clutch mastercylinder have anything to do with this? Would a dodgy clutch plate have this effect? Any other ideas?

 

Cheers.

you can check the engine mounts yourself with the help of a friend. Handbrake on, in gear and try to move the car slowly if the engine rocks a lot then the engine mounts are knackered, if not then they should be okay, the clutch may cause it, but you would get the car moving rather than the engine rocking

If your front engine mount was rocking alot for even a short time this puts alot of strain on your gearbox mount I bet you that the gearbox mount has gone as well which coukld be the cause for the engine to try an escape from the engine bay.Try what nigel has told you to do and see if the engine is still moving alot if it is replace the gearbox mount and that will surely cure your bucking bronco problem!! :D

Yep I agree with this - had to do same thing on my old 16V - the front mount goes easily as it is fluid filled. Once that goes the rest of them go too - replace all of them - the difference is amazing *:)

 

Scott.

 

PS. They arent expensive either!

Just replaced the gearbox one this morning. wasn't expensive and didn't take long (once I found out what needed done).

In fairness it did tighten up the engine a wee bit, but the judder on engaging the clutch is still there. :( . Its worse in reverse than 1st.

I might get round to getting at the other one some time, but methinks it's some other problem thats causing excessive vibration when engaging the clutch, thats causing the mounts to wear.

Would bleeding the clutch help. I have noticed that the biting point can vary a bit. Maybe a bit of air in the system could cause a bit of juddering???????????????.

or as G60Jet suggests - could it be the clutch? :x

Or maybe a Vibra-Technics front mount mount might help?

 

thanx

How many miles have you done and is it the original clutch first off all as that will be the biggest giveaway.

 

we know now its not the mount so forget about vibra tech for now at least.

 

Have you checked your brake fluid lately as it the clutch fluid too!!

 

Now if the clutch is dragging, my bets are on the thrust beering or plate being knackered, as thats what happened to mine. ened up with no clutch.

 

Take it to a Clutch specalist and get them to check it if your unsure.

I only have bits and pieces of history to now (118k) - nothing mentions clutch.

Brake fluid level looks good.

Mmm, now 'dragging' could descirbe another symptom - clutch sometimes doesn't separate fully and it'll clunk a reverse gear, and maybe a 1st. I'll take it to a clutch specialist then.

 

Cheers

Ah well,

Left car in to mechanic today and guess what, he said he couldn't get it to judder. True enough, took it home and the damn thing wouldn't judder.... - all day.... :x

 

No.... thats actually a good thing init? :D

maybe its fixed itself itself

Gotta love those self fixing problems :p

Nope, cause they normally show up again just as soon as you have put them to back of your mind, and leave you really annoyed!! :)

chuck, had this problem with my 16v. first thing is to make sure there is no air in the clutch master cyl system - it gets its fulid from the brake master cyl & if the level in there gets low the clutch can sometimes pick up air - even if the brakes level is good now there may still be air in the clutch line. If it still misbehaves after that then its probably the clutch master cyl - they do get tired and changing mine fixed the problem. I also sometimes suffer selection probs on reverse & first but vag said everything is ok - so I just touch 2nd to slow the shaft before selecting either which usually does the trick

Cool.... Sounds much cheaper than a clutch. Thanks, I will check that next time it starts misbehaving. Doesn't sound like a clutch to me either. If it was, I would have thought it would be jumpy all the time.

I know its a old thread but my c has started doing this,chuck have you cured your problem?

I seem to think its the rear mount but not to sure, front one seems ok ,and so does the gearbox mount,its the one at the far left rear that feels like its gone?

anyone had to change this one? and why is it far more expensive than all the others,

also it looks like a sod to change

regards kevin :shock:

Hi kevin I changed my rear mount at the weekend as I get alot of movement and a really annoying squeeking noise. The mount is really easy to change it took me about 20mins to change it all you need is a 17mm socket and wrench and a 13mm socket oh and a jack of course wheel off ubolt jack up engine take out refit JOB done!!! :D It didn't cure my problem though :( I think the front engine mount that I changed 2 weeks ago has failled again due to the rear one going!!! I dont know why the mount is so expensive I ended up getting one from work as the dealer stealers wanted £140 for it HAHAHA who in their right mind would pay that sort of money for one. I got mine for half that price!!!

Kevin,

Love to help mate, but I haven't seen my car in nearly a month!! :cry: Still in bits in body shop. But what I'm hoping to do when I get it back is first of all, bleed the clutch. If that doesn't work, replace the master or slave cylinder. Hopefully that'll work.

The engine mounts didn't seem to fix the problem.

thanks for the info bannana, had a good look tonight with the help of a few mates and it seems the front one is moving quite a lot ,put car up on ramps and back one seems good so me thinks i'll change the front one first to see if its that, front one moves about 1.5" when you put car in gear with brakes on,

chuck i have bleed the clutch and that did not help at all,

regards kevin

I used a genuine oe one from euro parts so it's not the quality chris its probably down to the fact that the rear one had pulled through it's mounts so the front one has been taking all the flack, I'll just kick up a fuss and get epc to replace it under warranty!!! :D VAG tend to add whatever percentage they feel like onto they're parts there is really no logic for instance the rear engine mount I got a genuine part from another source £60+vat Vag price £140+vat mark up of over 100% heres another one water hose from engine to heater valve genuine but from another supplier £3.50 VAG price £16+vat mark up of well god knows my brain is fried just trying to think about it!!! It just goes to show that there is a reason why we call them the dealer stealers!!!

Ant, sorry mate just couldn't resist the opening...

yeah I know what you mean about the prices. Actually I've been thinking the front mount on the VR might need doing, but haven't gotten round to inspecting it yet, a job for saturday. I haven't priced anything yet, are euro best would you say?

No not the best but are cheap and reliable imho if you want the best try a vibratech mount as they are far superior to any genuine mount if you can afford it that is!! probably twice the amount of a standard mount!!!

Got a new rear mount for £68 from ECP today. I had a look underneath the other day and saw a big dent in the down pipe heatshield. Looks like the rear mount is so knackered that the downpipe hits the steering rack :shock: . One possible cause of the knocking that is annoying me so much right now. If that doesn't stop the engine rocking about then its time for a VT front mount :) .

 

I hope it is easy to fit, as I've had my fill of spending all weekend under it recently.....
