Tomk Posted January 29, 2005 Report Share Posted January 29, 2005 ok dads 98' 4.2q sport - its dead ! no engine oil left and think that one of the pistons/rings may have gone, all happened very quick and stoped working , no bang of smoke or anything , local garage said they dont have the ability to really do anything due to the vehicle so am going to have it taken to amd, but anyone got any advice or any 'worst case' ideas also cost?

Botang Posted January 29, 2005 Report Share Posted January 29, 2005 Well simply enough, worst case would be engine swap, doubt if its worth rebuilding it, you would be better off buying a complete engine from a salvage yard. Itll be an ABZ engine I should think so there seem to be plenty of them around as it covered all pre facelift A8 4.2's I believe. Of course there is a possibility that some cleaver sensor has shut the car down before it went hugely wrong. Do you have any more information? was it driving at the time? Did the Oil light come on? any signs of leakage? It would be unusual I would have said for it to just go, these 4.2 A8's are pretty bulletproof. What sort of mileage is on the car? I go to DG Motor Services in Wellingborough with my car, they are a VW/Audi specialist, they deal with a lot of A8's (01933) 227277 ask for Dominic. They are closed now till monday though.

Tomk Posted January 29, 2005 Author Report Share Posted January 29, 2005 thanks will see dad over the weekend for more info , he was driving and the car just well died, felt like it was running on 3 pistons, warning light went on ,he pulled over,similar problem about a week ago, but he restarted the car and everything was fine.... again no warming lights pre to this happening, i think on of the rings has gone, is that i hard job to fix? better to do a swap ? how do i find a 'decent' engine , car is on 65k miles full history but not main dealer , whats the cost of a new engine do people recon ?

Ska Posted January 29, 2005 Report Share Posted January 29, 2005 Sounds highly unlikely that it is the piston rings...with only 65k on the clock! A friend of min had a similar problem with another audi; he was driving along and the car cut out and no oil. So these cars definately do have sensors to stop excessive engine damage, cos he only needed a new switch. Can you see any signs of a leak externally. may be worth checking the oil pressure switch, and all around the filter area; may be it leaked from around there. Again its a 4.2 V8 unless you've been thrshing the pants of of it, it does'nt blow up normally. Its worth noting that ECU problems sometimes show up as engines not quite working on all 8 cylinders. Did you get a diagnostic done? Good luck Link to comment Share on other sites More sharing options...
Tomk Posted January 29, 2005 Author Report Share Posted January 29, 2005 thats what we are waiting to get to AMD for , hoping the car has 'shut itself down' but there was no oil in it at all... there has been a small oil leak but at service they could not find it , and no it certainly has not been thrashed - maybee if it was my car Link to comment Share on other sites More sharing options...
Botang Posted January 29, 2005 Report Share Posted January 29, 2005 Only running on 3 cylinders, blimey whats happened to the other 5 I get what you mean though. It sound to me like its shut itself down, but then you have two issues, what has caused the it to shut down (should be able to tell that without to much worry with the help of Vag-com)and why has it got to that situation in the first place. If one of the rings had gone id think you would know about it, lots of blue smoke out the exhaust for a start. How long ago was it serviced? could it be something much simpler such as sump bung or oil filter not tightened correctly? I just had a look on the Russian site for you as regards price for a short engine (before I give you the bad news they are only guidance prices and can be way out) £5000 Link to comment Share on other sites More sharing options...
Tomk Posted January 29, 2005 Author Report Share Posted January 29, 2005 5000 ???? gulp ! would not get a new one i guess we will have to wait till amd can take a look and plug the computer in ! Link to comment Share on other sites More sharing options...
SneakyMcC Posted January 29, 2005 Report Share Posted January 29, 2005 Botang could the lack of oil be one of these fully synth jobs? No smoke etc? (I'm thinking compensation) TomK ask your Dad if he knows what oil was in it... Link to comment Share on other sites More sharing options...
Tomk Posted January 29, 2005 Author Report Share Posted January 29, 2005 not sure , would it make a difference? Link to comment Share on other sites More sharing options...
SneakyMcC Posted January 29, 2005 Report Share Posted January 29, 2005 These engines eat fully synth in no time. If a garage has put that in and the motor is phucked seek redress? Link to comment Share on other sites More sharing options...
Botang Posted January 29, 2005 Report Share Posted January 29, 2005 Think you will find its the drivers responsibility to check the oil. Link to comment Share on other sites More sharing options...
charlie61 Posted January 30, 2005 Report Share Posted January 30, 2005 You want to ring around a few local garages to see if any of them have experience of the A8 before taking it to an audi dealer I managed to find 2 in warrington in 10 minutes that had the equipment to read the fault codes, the 2nd one I found is a fully trained audi technician who has started up on his own and has plenty of experience of audis. I'm guessing here but I would imagine Audi loses a fair few technicians as they become cheesed off with earning £10 an hour while the dealers are charging £90+. It probably wouldn't be that difficult to find an audi specialist dealer near you. Link to comment Share on other sites More sharing options...

craigyb Posted January 31, 2005 Report Share Posted January 31, 2005 Charlie Can you post some details of this guy in Warrington, it would be useful to have his details when my warranty runs out shortly. Craig Link to comment Share on other sites More sharing options...
Tomk Posted February 1, 2005 Author Report Share Posted February 1, 2005 ok got an update, the following happened, the car is only driving on 7 rather than 8, the car just started to sound odd so dad pulled over, aa checked and there was little oil in it - but no warning light, took him to local garage, they checked and the 8th would not fire, they checked its one at the back, the car does drive, but only on 7, advised not to use it till its looked at, we are just waiting for AMD to fit us in, think it must be the ring. what do people think ?

Tomk Posted February 1, 2005 Author Report Share Posted February 1, 2005 oh and it is full audi service history, checked and they have done all the serivces Link to comment Share on other sites More sharing options...
SneakyMcC Posted February 1, 2005 Report Share Posted February 1, 2005 [ QUOTE ] think it must be the ring. what do people think ? [/ QUOTE ] Rings @ 65K Can only just be run-in. Hopefully summit small and leccy (may be even cheap!). Did you checkout www.audipages.com ? www.audiworld.com might be good too... G'luck. Link to comment Share on other sites More sharing options...
Tomk Posted February 1, 2005 Author Report Share Posted February 1, 2005 checked them out - no help just runs on 7, not 8 cant be something electric for that ? its not firing at all Link to comment Share on other sites More sharing options...
Tobes49 Posted February 2, 2005 Report Share Posted February 2, 2005 Ok, Few simple questions: Is it just not runnning on number cylinder 8?(staying on 1 cylinder) Have they done a compression check? Have they checked for spark and fuel to that cylinder? I would say you have got a electircal fault if you ask me. or a dodgy coil pack/amp unit. A damaged ring wouldn't cause it not to run on that cylinder you would ahve had to blow a hole in a pistion to do that. Link to comment Share on other sites More sharing options...
Tomk Posted February 2, 2005 Author Report Share Posted February 2, 2005 im thinking its got to be an electrical problem as there is no spark, not sure about comptession or fule to the cylinder, will find out tomoro i hope ! taking car over there , ive managed to borrow a van it will go on the back of !
