Having a spot of bother with my 1.9TDi Quattro. I dropped it off at the garage Thursday morning for the MOT, it passed the MOT and when I went to pick it up I asked them to try and free off one of the rear track rod bolts and when they tried to start it, it was turning over for ages and eventually started and ran (as if it has sucked air into the fuel system and was self-bleeding). The mechanic drove it onto the ramp and tried to undo the bolt, it was siezed solid so he went to start the car to pull it off the ramp and no joy. It turns over but doesn't want to start or run. It will start and run when using Easystart, by that I mean it will start and run until the easystart has burnt off and then it dies. The mechanics cracked off the pipes on the tops of the injectors and all 4 were spurting diesel so it's getting fuel and air as the Easystart was sprayed in through the air intake via the filter. It doesn't sound like it's turning over slowly, but the starter and battery could also be suspect. The battery appears to be the original one as it is dated 1997 and has done 178k miles if so. I've got a few spare batteries so will charge one up and give it a go. They were able to get it towed and it ran above 3k, when below this is stuttered and wanted to die, and if you didn't keep your foot down it would die. I'm thinking possibly my fuel pump as I have been getting error 01268 for a few months now. The only code he was able to pull off using his system was the same as above, and when cleared didn't return. This isn't a suprise as it will only come back when the car's running, and obviously it currently isn't! The other thought is that the timing belt has jumped on the pump only as it ran when towed and on easystart so the timing on the crank and cam seems ok. If the pump had jumped a tooth, would it run above 3k revs ok, but be rough below that? The only other work the mechanics did on the car other than the MOT was to screw the fuel pipes to the underside of the car as all the mounting clips had given up and I wasn't able to get them screwed up in time. The fuel pipe does have a few crushed sections, but not badly enough to affect fuel flow say the garage. I have previously replaced a small section of very crushed pipe and this made no difference to the running so I doubt this slight crushing will be the cause. Fuel filter was replaced a few months ago, and it's definately got diesel in as I fill up every week (do 500+ miles per week) and it currently running about half a tank. I have noticed recently that I have been getting slightly lower MPG and the car has seemed slightly down on power, but I don't think it's ever been perfect since I got it so I have no bench mark for performance. Not that this probably has anything to do with the non-starting fault. Thanks for reading all this, I thought it best to give a full description to help other members to diagnose. Hopefully somebody else will have some other ideas or have had similar problems and have a solution. Hoping to get the car back home later on today so should get a chance to look at it tomorrow, weather depending.
