Hi guys, I am new on here but wish my first topic wasnt a negative one!! Ive got a 54 reg Ibiza cupra tdi. oday I did a 90 mile round trip and when I got back to cambridge, i went down through the gears as I went round a corner about 1/2 mile from my house. I got down to 2nd, then when I accelerated there was a POP and i just heard the turbo spooling down. It wasnt a loud noise at all but afterward there was very little or no acceleration and the car was struggling to get over 15mph. I pulled over and turned the car off then back on again. it started fine but still wouldnt rev very high at all. I stuck the hazards on and attempted to get home. the car wasnt going anymoe than 10mph in 1st with my foot flat to the floor, like it was in limp mode. I got it about 500 yards down the road on to my road and it just conked out in a massive plume of white smoke. I tried to start it again probably 4 times and it was like it had a flat battery, it was turning over but very slowly. After this turning the key nothing was happening at all, the ignition lights come up and all the electrics work but the car will not turn over whatsoever. I checked the oil and although it was on the low side, I dont think it was low enough to do any damage. Ive tried disconnecting the battery and leaving it off for an hour but it is doing nothing. At no point were there any warning lights, nor where there any weird noises, no bangs or clatters!!! Im hopefully geting it to the garage tomorrow but as you can imagine I am going out of my mind with worry so if anyone has any possible diagnosis, it would be much appreciated!! My Dad seems to think the engine hasnt seized as you can put the car into gear and rock it
