andrew mouganie 0 Posted April 16, 2009 Report Share Posted April 16, 2009 Ok, came back from holiday, changed a load of thing in my car (neglected for a while) ecu, coil and fuel pump were changed now its a pain in the back to sart when cold. as soon as the oil hits 60C its fine. I get faulty lambda sensor and faulty water temp sensor when i diag but i assume its either the lambda or fuel pump, any ideas? Link to post Share on other sites
legvw 0 Posted April 17, 2009 Report Share Posted April 17, 2009 hi fella, it probably is the water temp sender as thats how the ecu knows when the engine has warmed up. Link to post Share on other sites
