Which country are you in?

UK cars come with 3 year warranty which would mean if you are UK based it’s covered until 2019.

SO it does have a full VW service it came up with a oil change needed at 39500 so took it in but not to VW but a garage that uses VW genuine parts, oil change was done no issues till yesterday.  its just a few miles within its 40k service How much do "goodwill Offer is there a VW rule of thumb used.

I wouldn't of minded so much if it was turbo/injectors but a major engine failure no.

I think it's fairly common, especially with major engine failure. They'll definitely go over it with a fine tooth comb, just making sure it's never been modified etc. Also one to look out for with manuals is that it's never been shifted into too low a gear causing the engine to go over max rpm - if it's ever happened the ECU will have a very detailed record of it.

I remember once putting into third not fourth from 6th it was very late in the night so wasn't with it, but I tried to put my VW van into second and first and you cant actually get the gear to select, its pretty poor at 40k with engine failure especially seen as there are other hot hatches running more BHP,

supposing I had done a wrong gear change it was at least 6000 miles ago and supposing this may have caused some damage ie cracked con rod would it of lasted 6000 miles,? I think not.

If you over-rev the engine (ecu will of logged this, so you could check with vcds before you hand it over to VW to save time and effort) it will most likely bend the valves not the conrod. You may not notice this at first but it could lead to lack of compression and/or bore wear, which may ultimately lead to total engine failure. Did you not hear anything unusual before the engine went i.e. knocking, metallic noises? Did you check your oil level? Do you warm the engine up correctly from cold?

 

For the less experienced drivers out there, the rev limiter built into the car when you accelerate will NOT protect the engine from exceeding max revs if you change down into too low a gear, so you could easily hit 8k rpm (or more), which is not good for the engine as the hydraulic lifters can't keep up at that rpm (which is why race engines use solid lifters).

Yes car gets warmed up before its driven hard and I am sure I have read that VW had put something internal on the ECU that doesn't  allow all the power until its warm,(but don't quote me on that) and its not really driven hard who can these days without a white van parked at the side of the road clocking your speed all the time.

there defiantly hasn't been any noises from the engine.  me and the partner drive most of the time without the radio on as we enjoy the noise sad I know.

I do understand what your saying but doing this once in 40k kills the engine? surely they are designed with enough brut to take a change down from say 5-3rd. or even 6th to third, as you can drive these in 6th at 30-40mph with ease.

The reason a Conrod comes through the side of the block is because the bearing has totally failed. This is due to no oil pressure, or no, or very little oil in the sump, conrods don’t “just” come off. I would say that there should have been some early indications that this was about to happen, , oil light comes on, definitely a loud knocking and vibration. The inspection to find the cause will be relatively easy, have you checked the oil level, there should still be some in the sump, is there a smell of something getting very hot, even though the engine is now scrap this odour will still be present. Remove the oil filler cap, is there a white residue on the underside of the cap, this would indicate water/oil contamination. Obviously further inspection would be needed to find out what actually failed, ie, bearings, or oil pump etc.. Be warned,, that VW will scrutinise every detail, oil filter brand, etc, to find away of not paying out. All the best anyway, hope you’ve got deep pockets.😩

No oil light. Even more worrying that when it was parked at the side of the road with the entire contents on the floor there was still no warning lamp,

although a couple of weeks previously I had a oil top up light so I did top up and checked thoroughly, I did check the dipstick but there was no oil on it as it was all under the car. I didn't check the filler wish I had of done though, there was no smell of burning, the only thing I found was chunks of the engine block at the back under the turbo. wouldn't all of what you had said of brought on a dashboard light?

all that happened was a loud bang followed by the car saying there was no- acc/loss of tyre pressure/no stop start available that's it, turned the engine off almost straight away.
