Hi all

Any ideas on this please.

Drove my Octavia 2 1.9 td 105 hp about 15 miles. Parked switched off. Fifteen minutes later switched on and tried to start. Got usual rer rer rer noise and just as engine caught , as it were, there was load bang from underneath the floorboards and a jolt or judder through the car. engine stopped. Tried again and again etc etc ---8 times in all. Same thing.

Just got out my info to find rescue number --thought I would give it one last go and it fired as normal as ran ok. It has behaved ok since.

I have a nasty feeling now that next time it does it it will be terminal and I'll be in the bowels of a ferry or 3 levels deep in a carpark.

Problem is how the hell do you demonstrate a problem like this to a mechanic.

Any idea what the heck it is? Please.

I had a similar bang or thud as if someone had just given the body a bang with their fist. :eek: It happend twice to me and then nothing. I was thinking it was the breaks sticking after it had been stood for a while and then sudenly releasing !! Very starange. Mine is a brand new TDI about 4 weeks old and so very consious of things going bump and in the night !!

Anyway, (touch wood) it seems to have stopped..

With any luck it will have logged a fault code on the ECU that they can read off with their diagnostic rig. You might also find that sticking it on a ramp will show them something - loud bangs usually leave some clues Was there a huge amount of smoke when you fired it up or any puddles under the car?

If they find out what it is, let us know

Surely that has to be accumulated fuel detonating?

It has happend to me once too on a 2.0TDi. No one said anything when I had it serviced so I am not bothered.

Very odd, only thing ive had go relating to start up was a dual mass flywheel that failed.

Just happened to me now.

Drove about 10 miles to my local Sainsburys. Did the shop, got into car and drove off. After about 2 minutes I'm at a roundabaout.

Just as I'm pulling away I hear a very loud bang, a shudder/jolt and the car stalls. It didn't sound like an engine stalling, it sounded like a collision.

I check the rear view mirror as I am absolutely positive the car behind has just rear-ended me - but no. I turn the key and the car starts no problem and I drive off the roundabout. confused.

Car's got less than 10,000 miles on clock, no had a service as yet.

Well whatever it is, it is common to the 1.9 and 2.0 TDI engines, as it happened during a pull off could it be something in the clutch or flywheel?

As it goes, I had a similar experience on my old Primera, a juddering and a loud banging under the floor where the dash is, turned out to be a fooked DM flywheel.

I'd drop it in at the dealer to get it sorted, or at least diagnosed.

At least it starts again, but it can't be good I'd imagine.

From experiance with the Furby vRS I had to give it higher revs than maybe one would expect and even when moving at say 5 miles an hour if I tryed to accelerate in anything but first without high revs it would stall, The stalling of a deisal motor IME is much more violent than that of a petrol motor and I did get some loud bangs jolts. The vans we drive at work Kangoos are also prone to stalling if revs low and spinning if revs too high (usually go for the latter). IMO the more powerfull/ higher state of tune the engine the more prone to stalling.

In your post you don't say wether the bang occurs after you lift the clutch or whilst the engine is just idling with no gear selected. if the former hope your mind is put to rest.

Thanks for the advice PostmanPat.

It happened as I was lifting off the clutch to pull away so it probably was a stall (how embarrasing?). But I've stalled diesels before (my last car was the old shape Octy for three years) and can't remember it being so damn violent.

I have also noticed that in this 1.9PD that you do have to feed it some more revs when pulling off than in the older 1.9TDI - maybe I'm just still adjusting to the new engine's dyanmics.

But thanks again.

I have experienced exactly this a week after collecting my car. Pulled onto a roundabout and stalled so violently with a shudder and bang. I was convinced something had disintegrated it was so bad. Never happened again. I have stalled it a couple of other times since but they were just "normal" stalls, no huge bang. How strange.

I had this happen to me too. Coming from a 130PD Octavia 1 to a 2.0Tdi, I found the 2.0Tdi more prone to stall, particularly when cold, and it usually does so with a bang and a shudder. My 2.0Tdi has done 23K miles now, with no ill effects.

I've also found that if you try to pull away immediately after the engine has fired, you may hear some nasty bangs then. I'm guessing that's probably caused by lack of oil pressure on the crank, so I always give mine a few seconds to build pressure.

the problem is most likely the flywheel springs after coming apart inside the gearbox get it checked ASAP as it could cause more damage at worst it will not go and the gearbox is sheared away GET IT SEEN AT YOUR DEALER NOW

So these occasional, seemingly random stalls I've been having, when I'm sure I've pulled away with the same clutch / throttle transition as normal and I get the horrible loud bang (worse than a normal stall) could be due to the DMF springs sticking?

Never had this happen in our 2.0 TDi DSG auto - if it only happens in manuals, then it has to be clutch/gearbox related.

My 1.9TDI did the "violent bang" thing today. I had driven for 12 miles, switched off for 10mins and then it happened a couple of seconds after the engine had started. I was watching the revcounter at the time and the needle didn

A friend who I had persuaded to buy Skoda asked me about ths the other week and I said I'd never heard anythign like it and then last week mine did the same thing. As others have described it was as though someone had thumped the roof. I was reversing out of a parking space and the car did not stall so it's not that. My wife was convinced we'd run somethgn over so we were both out looking to see what (or who) we'd hit. Of course there was nothing there at all.

Very very puzzling.

Found the problem !!

In my case it would appear that there is a dodgy connection from my CD player in the boot and the radio !! Yes, when I turn on the ignition a few seconds later there is an inormouse bang that comes from the speakers, and Yes I also ducked thinking something had landed on the car. I only reallised when one time a message came on the LCD display saying the CD was faulty and the radio didn't work.

I fiddled around with the connection that plugs into the CD player in the boot and it all started working again.

Its been ok for a couple of months now but yesterday it started again. Maybe this connection is just working itself loose?

Worth a check guys.

Glad you've figured that out, but that isn't really what this thread is about. This is about a mechanical issue complete with violent shudder.

Wow that could be it.

Very soon after the noise I decided to change the CD that was playing by pressing the button on the stereo and it came back with "CD error"! Also, over the previous few days I had been having problems with the sound coming and going from the left hand side speakers - but only when playing a CD from the boot - radio and front CD didn't do it.

I'll check the connection, when the rain stops, and report back.

My Stream player did that loud popping noise too, till i swapped it for a MFD2 unit. I get the loud bang and stall too occasionally and put it down to a, pilot error - D'oh 3rd gear again! and b, ever noticed that the engine sometimes 'hiccups' when driving, it does it at the worst time - when setting off!

This occasionally has happened to me. Start the engine, it just catches and then dies very quickly with a big shudder and a loud bang. Starts immediately afterward though.
