Hi guys,

Just picked up a lovely looking Laurin and Klement at the auctions here , 2006/2007  2.0l

 

anyway i was pleased until i drove it home and noticed it has a judder to it,  lots of smoke out the back when floored,, but i heard the engine before i bid and did not hear any rattle from the flywheel at all,   it sits smooth tick over,, i am pretty confusied as to if its the clutch or not? 

anyone got any ideas,, i been trawling through the search judder but none of them seem to come close to what i felt except a drive shaft but i dont even know what that is or where it is! ,,

if it was the clutch i would hear the rattle right?  or is it possible the dsg box doesnt always rattle when the DMF is on way out? 

i can floor the accelerator and get smoke out the back and judder in every gear,, the gear changes are really smooth as they should be so it got me confused as to if it could be another problem,, hopefully cheaper to fix!!

 

any ideas please guys

Also there are no codes what so ever showing, no engine management lights nothing, so got me stumped

If I have the car stationary and have my foot on brake and then press accelerate the car try's to move but then goes up to around 2000 revs and just drops back to try again .......it won't continue trying to move the car 

 

this is very strange to me ,,I thought there should be a noise if DMF , so maybe the clutch is going?  Anyone ever heard of this ?

 

another reply by me! haha,, well i just took for another run ,, the judder in every gear but changes seem smooth,,   when i came back to stop when i flick through the gear changes whislt stationary there is a click when engaging D then going to R between as soon as i engage the gear it clicks rather loud underneath the car,, is there any way of checking it has dsg oil in it? i thought these are sealed units,,,,

very sad with this now ,, if i knew how to fix it  would be better ,, but think i will sell to someone who knows how to fix it :(

I have been reading internet all weekend and it maybe inner CV joints, drive shaft, dsg oil,, so many ideas of what it could be,,

 

could someone tell me if the DMF would also be a cause of what is happening to me?  there must be a member that this has happened to?

 

 

anyone at all

cheers

I can't answer all your questions but if yours is a 2.0 tdi they run the 6sp wet clutch dsg. They do need oil and filter changes for the tranmission every 40k.

 

You can check there is oil by getting the car off the ground and keeping it level and removing the dsg sump plug with the engine running. A small amount of oil should be ejected. This shows the oil level at top of snorkel. Do not remove the snorkel underneath the plug unless wanting to change and replave oil.

 

The oil condition may also indicate if there has been recent changes or if there is a terminal failure like an oil cooler perforation.

 

Maintenance of these tranmissions can be overlooked.

 

As for vibrations it could be a driveshaft problem. Particularly if the problem gets progressively worse with roadspeed rather than engine rpm whilst driving. 

 

It is a matter of eliminating the obvious cheaper type faults. If the transmission needs work it will be £££ and probably specialist work. Clutch pack and dmf would be well over 4 figures.

Hey thanks for the reply,  I found a receipt today in the car for a service where the gear box oil was chaged at 86,000 miles in 2013,, miles now at 134,500,    car seems well looked after so this is a bitter pill to swallow ,, do you think it is possible the car would run like this just with old DSG oil? 

the car only judders when i have my foot on the gas,, when i am at speed and i just cruise along there is no judder,, it seems like the car is getting power but is not using it ,,, or has some kind of blockage to stop running smooth,, i been reading internet all weekend, even now i am looking at utube for probelem , only thing is now i have a lost of so many things it has really confusied me,  maybe even injector seals i saw made a judder problem on another octavia 2l tdi

,,but i have no fault codes so am still baffeld,

thanks

Its not massive mileage and only 10k over if the receipt is correct.

 

I doubt that delay would cause the sort of problems you are describing. More likely poor shift quality.

 

Are you sure it is a transmission problem and not an engine missfire or vibration. Checked all engine mounts.

 

A knackered clutch pack would often go with poor shift quality. Maybe not always but often or poor take up from stand still.

Thanks for your reply, i appreciate having others give me advice as it helps me identify the problem i hope, i will drive it again tomorrow theclient and hopefully get some more idea what it is,

thanks

Do you have any idea if a DMF would cause what i am experiencing?

Yes, DMF is a distinct possibility. If cv / driveshafts ok. [Edit: Engine not misfiring.] All engine mounts secure. But you would replace clutch packs at the same time anyway given the work at getting to it. And try to get a diagnosis confirming it from the garage that will repair before splashing cash. Even the clutch packs require a garage with some experience and a LUK certification.

 

To help prove it, you can try to use DSG manually, hold in a high gear 4th, 5th or 6th. Low revs, hard on throttle. On off throttle a few times. Lot's of vibration could well be DMF.

 

Edit: Be aware if the DMF is very poor, it could fail in normal driving or provoking it, in the way I describe.

Hi, just like to update this,,, i took the car to mechanics and had it up on the ramp,, he wigged the drive shaft drivers side with hand and it rattled, was quite worn he said, so i have ordered a pair new ones for bother sides to be sure from flea bay,

fingers crossed this solves it,, i will update here soon as i know,

just shows that a very worrying thing is hopefully going to turn into a much cheaper fix ,, thank gawd

could be a good outcome. Let us know how you go.

Well orderd the drive shafts from flea bay and they arrived yesterday,, had a mechanic fit both and now the car is running like it should!!!! smooth as silk,, i very happy that this was not a major problem!  

 

great and thanks to all the info here as i wouldnt never have known what it was!!!

 

so if you ever get the judder inner CV joints known also as drive shafts! could well be the culprit,,,

 

cheers guys

Great, well done. Good outcome. Don't be afraid to use the thank buttons that appear under the love hear on the right of posts.....

Cheers!!!   all good ,, and i must the octavia is a firm comfortable drive now!   but i am still impressed very much with the fabia 3 i had,,,,,,

Why would that be strange, the car won't try and move if you have the foot on the brake. The ECU cuts the power for safety if you press the brake and accelerator together

 

A failed DMF can seize solid making vibrations bad without any noise, so bear this in mind in the future

I understand the physics behind it ,,   i thought the car had some kind of take off acceleration so was trying to get that g-force with doing this, , ,, and of course i should not be in euphoria to long with my problem seeming solved as there could alweays be another rpund the corner,,,,,

thanks very much for your advice, ,, all be it a little after the hourse has bolted from problem,,,

cheers

To the OP: Don't forget, your DSG unit sounds like it may be overdue a fluid and filter change.  Now that you seem to have avoided more expensive problems, it would be a good time to make sure scheduled maintenance items are all up to date.
