Rocket_Man Posted February 19, 2007 Report Share Posted February 19, 2007 Last night while driving my engine cut out and wouldn't restart. Whilst waiting for the AA I did a VAG-COM scan which showed the following fault codes: 7 Faults Found: 16684 - Random/Multiple Cylinder Misfire Detected P0300 - 008 - Implausible Signal - Intermittent 16685 - Cylinder 1: Misfire Detected P0301 - 008 - Implausible Signal - Intermittent 16689 - Cylinder 5: Misfire Detected P0305 - 008 - Implausible Signal - Intermittent 16687 - Cylinder 3: Misfire Detected P0303 - 008 - Implausible Signal - Intermittent 17755 - Camshaft Position Sensor 2 (G163) / Engine Speed Sensor (G28): Incor. Correl. P1347 - 002 - Lower Limit Exceeded - Intermittent 17745 - Camshaft Position Sensor (G40): Short to Ground P1337 - 002 - Lower Limit Exceeded 17799 - Camshaft Position Sensor Bank 2 (G163): Short to Ground P1391 - 002 - Lower Limit Exceeded The ever AA diagnosed a snapped timing chain, although the chain still looks intact under the oil filler cap (it just doesn't move. Has anybody ever heard of a similar issue and what the problem is? Thanks from one very sad R32 owner Link to comment Share on other sites More sharing options...
Decked Posted February 19, 2007 Report Share Posted February 19, 2007 Eeeek... I think JimmyP may have an idea of what's going on here! What ever has happened it doesn't sound good. Best of luck Link to comment Share on other sites More sharing options...
Oatz Posted February 19, 2007 Report Share Posted February 19, 2007 Oh dear poor you , I have heard of timing chains snapping, in fact someone on here mentioned it recently. Hope you get it sorted maybe worth a call to VWCS for a 'goodwill gesture' and maybe worth not metioning the mods Link to comment Share on other sites More sharing options...
timk Posted February 19, 2007 Report Share Posted February 19, 2007 Think I've asked the question before, but are you supposed to change the timing chain at any point in the engine's life to prevent this kind of thing happening? Link to comment Share on other sites More sharing options...

dogbucket Posted February 19, 2007 Report Share Posted February 19, 2007 I know the error logs do not always point straight to the problem, but if the cam sensor died I guess it would missfire a bit before cutting out. Link to comment Share on other sites More sharing options...
AndyE Posted February 20, 2007 Report Share Posted February 20, 2007 I had heard about premature engine wear around the timing chain and timing gear when I bought my .:R. The genral concensus of opinion is that the longlife servicing was to blame, so I have taken mine off longlife now. Didnt R32guy off uk mk iv's have a similar problem, not until after he had his turbo conversion fitted, but he also had an AMD stage 4, so maybe the fitment of the cams had something to do with it Link to comment Share on other sites More sharing options...
jimmyp Posted February 20, 2007 Report Share Posted February 20, 2007 I'm postive someone posted on here about a snapped cam chain before, and no it wasn't me result was a new engine obviously, tho with having the AMD stage 4 this will no doubt void the warrenty, i hope having that didn't cause the engine to die and the cost of having a replacment engine and labour etc...£6500+ thats what mine came to last time round...

Rocket_Man Posted February 20, 2007 Author Report Share Posted February 20, 2007 VW had the car today and confirmed a snapped cam chain. They also said that i have bent some valves as you would expect. Tomorrow they are going to take the head + gearbox off and confirm how bad the damage is. Currently I’m denying engine mods besides the CAI in the hope that i might be able to get some sort of good will (warranty ran out in November). I’ve spoke to several people and nobody has heard of this happening before. For the time being it looks very expensive. Already can’t wait to get it back! But if i do get a new engine i’m not looking forward to the running in or the drop in power One question is, if they change the engine, will the ECU get changed? I’m sure the stage 4 code wont like a stock engine.... Link to comment Share on other sites More sharing options...
Gti_Fly Posted February 20, 2007 Report Share Posted February 20, 2007 I doubt they would change the ECU tbh. Link to comment Share on other sites More sharing options...
Rocket_Man Posted February 20, 2007 Author Report Share Posted February 20, 2007 Thats what i thought. I'm hoping there's not much damage and they can just fix it (with my existing cams). It does look like i'll be coming clean and dragging some mothballs out the bottom of the wallet Link to comment Share on other sites More sharing options...
AGK512 Posted February 20, 2007 Report Share Posted February 20, 2007 When the cam belt went on my 306 I was only going slow downhill and 'got away' with a full set of valves, guides and sundries and alot of labour at a reduced rate £1300 ish all in so it might not be as scary as you think Link to comment Share on other sites More sharing options...
Rocket_Man Posted February 21, 2007 Author Report Share Posted February 21, 2007 I was only going 45-50 in 6th gear so was just idling. There was no banging or grinding. The engine just cut out and wouldn't start (still nothing nasty besides miss-firing). I still don't know what i want. On the one hand, i just want the car back ASAP with the same power. On the other, a nice new engine with ZERO miles would be nice (its done 54k now). Although it would be going back to AMD once run in, i just know it'll feel too slow without. Whatever happens, there's nothing else out there i want to swap to right now so i'll be keeping it for the time being. I still have a bad feeling that this afternoons phone call wont be good Link to comment Share on other sites More sharing options...
Oatz Posted February 21, 2007 Report Share Posted February 21, 2007 Oh God this is exactly the reason I got shot of mine in the end... too much of a ing liability. Hope all goes well for you with VW Link to comment Share on other sites More sharing options...
Rocket_Man Posted February 21, 2007 Author Report Share Posted February 21, 2007 An update at the end of play today is that i have at least 8 bent valves. They are still to look at the valve guides but they said there was no damage to the pistons The tech said the cog on the crank was badly worn and he thought that was the cause of the failure. I only have 54k miles so some of you with lower milage cars might want to bear this in mind. They are currently prepairing a price list and i'll get a call tomorrow. Besides the clutch is there anything else i might want doing whilst the engine and gear box are out the car? Link to comment Share on other sites More sharing options...

[/ QUOTE ] Jimmy may know better, but that suggests to me that your car suffered from the crankshaft end float / incorrectly shaped bearing that meant a few of us on here had new engines ... It's something to explore - maybe also by having a specialist such as APS examine it - because that would indicate to me that VW should pay all your costs Link to comment Share on other sites More sharing options...
jimmyp Posted February 21, 2007 Report Share Posted February 21, 2007 I would say Ross isn't far off there, i would get them to measure the "float" first off and find out the measurement then i would be seriously asking questions to why this happened! A worn cog just isn't a good enough answer! I would hazard a guess that possibly you may have had incorrecty specced thrust bearings, the dreaded cause to the exsessive endfloat/crankshaft problem. Did you suffer form any engine rattles, clonks or the clutch feeling heavy after a long motorway drive (after left in a gear for a while) or the gear changes being very notchy?? I would definitely ask for the fylwheel to be replaced as this is/should come part of the clutch kit aswell as the release bearing. And as Ross says, getting a specialists such as APS to have a look wouldn't be a bad thing either... Link to comment Share on other sites More sharing options...
farmerpalmer Posted February 21, 2007 Report Share Posted February 21, 2007 Sorry to hear of your bad luck Rocket Man -know how you feel . Had a 306 GTI-6,and snapped cambelt at 50k, only doing 10-20mph. Pistons fine, but needed 8 valves. Cost £1300 (£1000 labour). Even though was 3 years out of warranty, got main dealer to pay for the lot, as had full pug SH. Hope you get it fixed soon, and get it run in.

Oatz Posted February 21, 2007 Report Share Posted February 21, 2007 If its the intermediate sprocket then this is also know as a weak design point on the R (incorrectly specced part from a sub'd out company on a batch of R engines) was also reported in Volkswagen Driver a few months ago via AMD Link to comment Share on other sites More sharing options...

[/ QUOTE ] Nothing like that at all. I've tried listening for the rattles of death after you had your issues Jimmy. The only sign i got were a few split-second flat spots that appeared during the final week, and these were only while accelerating hard. Oh and i'm told it sounded a bit rough when i set off on my final journey. Unfortinately i had decided to try some Tesco 99 and put it all down to the car not liking the fuel. BIG mistake there.....

Rocket_Man Posted February 22, 2007 Author Report Share Posted February 22, 2007 They checked the float today and they say it's "well within what it should be". The bad news is the head is more damaged than they thought and needs either reworking or replacing I've left them to talk to VW UK about good will......

I was going to ask that the figure be put in the paper work anyway. Hopefully when i get home tomorrow I’ll have my R32 Die cast model. That should keep me a little entertained till the real thing returns. Cue the dodgy child-like Milltek sounds Link to comment Share on other sites More sharing options...
