Yet another tailgate issue on my Accord Tourer 2007 CDTi post-facelift. Alarm started going off at random, not frequently but 2am is always bad. After alarm the car would not lock on the key. Honda dealer suspected bonnet catch and disconnected it but didn't do a test. Wasn't that. Then tailgate open warning came on while I was driving - ah I thought that's it. On checking found that car had been bumped in a car-park. Externally damage was very minor surface scratches but underneath the metal was distorted meaning that the O/S bottom corner was 10mm further closed than the N/S. Knocked out metal and reduced this to 5mm. Did ECU reset - battery disconnected for > 20 mins. Reconnected with tailgate up, manual shut. OK for about mile then the tailgate alarm on again. Retried reset a number of times but no consistent result. Thread at Honda Accord Tourer Tailgate issues and trobleshooting (Pre-Facelift Model - ) was very helpful. Checked wiring as well as possible - no broken wires visible but of course could be wire not insulation and a lot is protected. Checked the sensor gaps (bluetac) about 5mm on all of them. Moved the locking mechanism forwards now cannot get the light to go out after reset. Same when moved back. Would be happy to disable the sensors (I think) but simple disconnect seems not to stop the tailgate open state and stops the electric shut. Do I need to get in the heavies and twist the tailgate to get rid of the 5mm mismatch? Can I short out the sensors or move them? As there is an another £320 bill for a binding calipers and it needs two new tyres this could be the end of the road.
