Hi folks 1st post and I need lots of help! Golf mk5 2008 2.0 BKD Last summer I bought a heated leather interior and fitted it with the intention of eventually getting the heated seats working. In Nov I bought a Kufateck loom and installed it according to the instructions. Somehow I've managed to screw a lot of things up! Symptoms: 1. Park assist intermittently makes strange noise. 2. Indicators in speedo cluster and door mirrors flash out of sync with front and rear indicators. 3. Auto Door locking goes bananas when driving. Locks, unlocks, locks, unlocks. However I can stop this by turning off the auto lock setting in highline cluster. 4. Convenience setting in highline cluster is sometimes not accessible. 5. Speedo cluster illumination flickers intermittently 6. Switching on the blower makes relay 373 on the panel above CECM click on and off every few seconds. 7. Car alarm goes off after locking car intermittently. 8. No cruise control Parts I've replaced: 1. CECM with an identical part number, with no change to symptoms. 2. Steering wheel control module, but horn won't stop going off. 3. Cruise control/indicator stalk, with no change change to symptom. 4. Hazard switch, with no change. 5. Relays 373 & 370, with no change change to symptom. I've had it scanned with VCDS and it can't communicate with the central electrics, door controllers, steering wheel controller, heater blower controller or parking assist. The expert who scanned it said it has to be linked with wiring or relays. I'm absolutely stuck on what to check next, where or how do I start to check the wiring? I want to have a go myself before dropping by it off at an auto electric garage and facing a huge bill.
