Audi S3 Snapped Cam Belt advice?

The OP does, and it's all the more reason to kerb useless comments like "My mate's broke a chain too, audi crap ha ha" isn't it.
It's not really useless though is it if it's happening on the same engine that's covered the same mileage. A chain should last many tens of thousands of miles, not 30k.SuperchargedVR6 said:
Audi don't make chains. Chains have snapped or worn out on all sorts of cars that use them. BMWs, Jaguars, Mercedes to name but a few. They are like bike chains, they wear out.
Audi don't make chains but they do specify a chain, grade, and supplier, produced to a price, along with guides and tensioners. It happens with too many marques, presumably the bean counters offset warranty costs against savings.
Well it's not confirmed snapped but garages best guess without doing more work. They have confirmed it's not the belt and also tested the engine and it's got no compression. They have said it's most likely the chain but without taking the cams off they can't confirm. I'm waiting to hear off the garage I bought the car off before I give the go ahead for more labour as already cost £95 and don't even know 100% what's wrong with it -.-
It's a specialist audi garage but not official audi garage. It's because they had to take parts of the engine off to get to the belt to check it. To go further they would have to start stripping the engine to find out what damage there is internally apparently.
They have reduced the cost to £30 cos I only asked for a diagnostics, they just got giddy and started taking s
t and apart

To have no compression on any of the four cylinders means something in the head (damaged valves) or failed piston rings.They have reduced the cost to £30 cos I only asked for a diagnostics, they just got giddy and started taking s
t and apart The most likely is head/valve damage and this would be consistent with the chain snapping as this times the camshafts and therefore valve operation
If it's the chain driven engine, it'd take any half decent Audi specialist all of 15mins or so to remove the top plastic timing cover and see if the chain is in one piece still. No need to take the cams out at all? Or even remove the bungs on top of the cylinder head cover, spin it over and see if said cams turn.
Seen a few tensioners go on those engines, but that's usually on start up. Also seen 1 1.8tsi snap it's chain in half a few months ago, think that was around the 60k mark it let go.

If it wont turn over (I think you did say that right?) how have they done comp test?
The last thing you want to be doing is a comp test on an engine that has suspected timing gear failure. You don't want to turn the crank at all?
If it was me I would be getting a scope into the bores pronto - will soon tell you whats what.

£95 and all they've managed to ascertain is that it has no compression? Which garage is it Kwickfit?
It shouldn't take hours to be able to remove the rocker cover and see if this chain has snapped or perhaps the tensioner has failed.
Either way, any garage that continues turning it over without having a clue is only causing more damage! No compression at this stage could mean a handful of bent valves, continously turning the engine over will only result in more damaged valves or worse wrecked pistons.
When my timing chain snapped I ended up replacing all but 1 of the valves and have half a dozen which are now novelty paper weights/. Luckily as I realised quite quickly what had happened and prevented the AA from turning the engine an simply dragging me home I was able to get away with having the valves replaced, a skimmed head , head gasket an timing chain kit (£600) an I was back up and running.
Well it's been a pretty heated battle tbh. They aren't accepting liability as it's been over 6 months since I purchased the car but then I had a specialist audi garage inspect the car and produce a report saying that mechanically it has been well looked after and the cause of the fault is most likely defect. That along with along long winded email citing the consumer rights act and and a factual Google review and they seem to be playing ball.
I got an email today just saying "we are pricing up a replacement engine, I'll be in touch shortly" so fingers crossed it's getting somewhere.

Guy at works scirocco 10 reg, has just done the same, it's costing him over £3.5k so far, they have put a new head on it apparently, iim guessing a used item, vag specialist in Guildford,
Because they reckon it's cheaper than lapping in new valves etc, I didn't say to much as dont want to get involved
But I reckon they are taking him for a bit of a ride, his dad looked at the head and there was no apparent head damage just bent valves sounds like they have a nice little exchange head from last customer quick turnaround and profit system going

Yea my garage just said they can charge me a few hours labour to take the engine apart and determine the damage but then it will cost between 1200 to 2000 possibly more to fix depending on damage. A new engine would negate any possibility of reoccurrence and would come with a warranty etc incase anything did. Either way they only charged me £54 for a diagnostics and an hours labour. Then I have paid £45 to have the car loaded and brought back to me house today so I'm only £100 down so far so not doing too badly.
Fingers crossed the garage I bought it from would rather pay for the repairs than get into a legal battle.

They aren't 100% certain but they believe that something caused the cam chain to snap, and they think it might be a faulty oil pump or something. But they said no point going through all the steps of trying to discover the cause because it will cost all lot and ultimately may not fix the problem. A new engine is going to be similar cost and more reliable.
