Ecm goes bad it will go in limp mode, vechicle will run poorly check engine light will stay on vechicle wont start.you need to use a code scanner check for ecm fault code, if check engine light not turning on when you start vechicle could have blowed ecm fuse or wiring problem, could have loose connection at ecm electrical connector or ecm getting poor ground but first check for a defective ecm using a code scanner.

Testimonial: "thanks....its driven me mad,since i been last on i brought it 2 a garge,his sayin its the ecu box,so hopefully,it b sorted soon,thanks 4reply"

    best have vechicle code scan, if ecm is defective fault code will let you know if pcm if faulty.

Replacing the ECU on a 1999 VW Passat Sedan 1.8 Turbo

if u have an electronic key than security codes from ur key must be programmed into the ecu to match-- most ecu change overs on cars usually require a trip to the dealer so they can install their programming most auto shops dont have the funds to, or customer base to spend thousands [every auto maker has their own software and update and change every year]-- every year on reprogramming software for ecu-- they may do only 1 or 2 a year

Where is engine control relay 2005 passat j271

remove the plastic plenham chamber cover (at the base of the windscreen). this is the big cover that hides the battery and brake master cylinder. you will see a plastic box. undo all the screws that hold the lid on and reomove. the screw at the back can only be accessed by popping out a small grommet from under the wiper arm.
the engine ECU and the relay that powers it are both in the box, there will also be some fuses here as well.
