I am having major problems with my K13 dig-s. Was initially going into limp mode with eml on. Error code was P0011. Done an oil change, changed spark plugs and air filter and still would not start. Replaced battery as auto technican said mine was shot... at a cost of £248 (stop start). Other advice he gave was to take it to a dealership as he had not worked on a Dig-s engine before so did not know how to fix it as it would still not start. I then replaced the inlet solenoid valve in a last ditch attempt before heading to dealership. Car now starts and drives but has a very rough idle where I can feel the car pushing to keep engine running. Drives jittery with a loud whistling noise, mainly on acceleration and mpg has dropped to 16.4. Oh and I can also hear a clunking noise when air con goes on that was not there before. Not throwing up any error codes anymore. Any help would be much appreciated!
