Failure of the system or running out of fluid may well result in the DPF clogging. I wouldn't want to change the fluid myself, but many have, but the counter must be reset using Lexia/Diagbox. Failure to reset will result in no fluid being injected and the risk of the DPF blocking. I really hope I have explained everything clearly!
Hello, Im going to change my transmisson fluid in my c4 picasso 2.0i 2007 automatic petrol but wondered if anyone could tell me the excact amount of oil to re-fill it once its drained i think its 3.1 litres but if anyone could confirm would be awesome also im not 100% sure where the transmisson drain plug is?
Generally, if your C4 Grand Picasso has an automatic transmission, the transmission fluid is changed every 25,000 to 30,000 miles. If your car has a manual transmission, you should change the transmission fluid approximately every 60,000 miles. How does the transmission fluid work inside your C4 Grand Picasso and where does it go? FwIECbV.citroen c4 grand picasso transmission oil change
