redstone 0 Report post Posted December 13, 2015 Hello, OK here is my problem. Every winter ,almost every morning I get the same error "have gearbox check". (only at first cold start). 1. If I parked during the night at any other gear but "N" I cannot shift to "N", thus cannot start the car. (Usually the error is gone after 5-10 minutes and I can shift to "N" and start the car. 2. Because of the above, I always park at "N" yet even than, I get the error "have gearbox checked", but the error is gone after 1-2 minutes and I can shift gears. (No problems till the next morning). 3. Today I plugged OBDII get U1711. 4. The pump always starts when I open driver’s door. 5. Battery tested and found OK. 6. I read it might be a gear sensors but could find which one and a part number. 7. Any other season but winter the car runs perfectly. I’ll appreciate your help. Thanks Quote Share this post Link to post Share on other sites

It's normally just moisture in the plugs that evaporates after you've warmed the engine and gearbox up. Quote Share this post Link to post Share on other sites
