Hi, All! New to this forum due to having recently been sold an X-Type by a family member for £300 with MOT until January 2026 - uncle got the dreaded glow plug light and “gearbox fault” after he had the dpf removed. Being mechanically minded I decided to take a look whilst I borrowed the car. After about a week he said I can have it for £300, so I managed to narrow down the problem to the Turbo actuator, the control arm for the vanes is as free as fresh air in the countryside. I opened up the actuator to find one of the small wires to be loose - the usual culprits near the connector to the worm gear. Upon scraping away the silvering for the weld i managed to nick the one next to it so decided to scrape down to the copper on both wires and place a new wire on both, so 4 copper pads with a small wire bridging the 2 pairs. Obviously I’ve added extra length to allow for expansion under the heat. Results are: The glow plug light has gone (or hasnt showed up so far) but the auto box somehow hangs in 3rd whilst accelerating up to about 3000 rpm (not exactly hard acceleration either - just as I’m joining a motorway and such) and forcing me to upshift myself using sport mode then putting back into standard. And also at lower speeds (under 30) it feels as if the car is trying to shift up but doesnt quite get there so can judder a little until I put my foot down to force it to shift. Now my question is… does the ECU have to relearn to drive after being disconnected from the battery? If so, how long will that take? As I’ve already done around 50 miles since the battery had been reconnected. Any thoughts? 2009 X-Type 2.2D Automatic
