I have had my 2003 C5 2.0 HDI Auto Estate for two days now, and love it to bits, however, the fun is over and I now need help :( The C5 is a work of art, it's got 70,000 on the clock and is as close to perfect as you can get for a car of this age. I went out today to take some rubish to the tip, so far so good. On the way home (about 1 mile) I stopped at the local supermarket to pick up a few bits. When I went to drive off, the revs went up to 2.5k and the car never moved. I checked I was in Reverse and nothing, just felt like the clutch was slipping badly. I turned off the car and restarted, tried again in reverse and car moved but very slowly and revs where at 2.5k. I then put it in drive and it did the same thing. Next I tried manual and in 1st gear high revs and nothing, in 2nd gear it moved but slipping alot. I got her home and the service light came on (no warning lights or messages before that) When I brought the car I did notice that the last owner had a problem with the gearbox (auto gearbox fault) and he took it to Citroen main dealer, his bill came to £200. All they did was check and replace gear oil and reset fault code. They said gearbox was ok and it was just a blip. (common term for...we dont have a clue). I have a Lexia 3 which I had only just setup on my laptop yesterday, for the soul purpose of reseting any error codes in the future (24 hrs later and I get to use it). I checked the car first to see if it would drive and it was still slipping like mad. I ran Lexia 3 on her and it came up with 3 errors. 1. Radio aerial fault (someone had nicked the aerial) 2. Coolant gauge short error (coolant gauge stopped when I first went out today, but after I restarted the car it worked again fine) 3. Auto Gearbox error (clutch slipping/brakes) Brakes are fine, I checked. Well number 3 was what I said, the clutch is slipping and about to go. I reset the codes and turned the car off. Laptop disconected I thought I would start the car up again just to make sure the service light had gone out. Yes light was now back to normal :) Like you do, I just had to try her in drive for the last time....well bugger me....she works, yes folks, she works in drive and in manual. I just had to go for a test run (I know, i'm sad lol) I went for a good run on the back roads, lots of start/stops....no problem. Quick spin down the motorway at 70mph and she dont miss a beat. Gears are changing up and down the box as they should, but I still think 1st & 2nd gear are not as good as they should be....maybe a little bit of slipping or just slow to change up a gear. Once I got home, I put Lexia 3 on and no faults or errors showing. Something is not right here....is the clutch on the way out or do I have some gremlins in the electrics or sensors ??? Tomorrow I will do a system reboot (bsi or something its called) and see if that helps. George
