So i recently got this well used Passat 2006 2. Ot Fuel but the Immobilizer Active message display which wouldn't let the vehicle come on could drive a sane person insane. I notice this becomes very intermittent during the day time when the weather is high as it rarely happens in the mornings and evenings. A technician advises me to change ECU which i did , vehicle runs for 3 days displaying different incompatibility signs and finally parks up after 3 days. Now i am back to old ECU with very intermittent Mobilizer Active messages. Anyone has an idea how to manage this ?
Thanks to hearing back.

Until four weeks ago, i would have rated my passat as one of the best,then during a mot, i was advised that the front tyres were going to need replacing. I replaced them two weeks ago fitting bridgestone 235 /45 / 17 to replace old michelins. As soon as they were fitted i noticed severe shuddering from the back end, with very uneven running back tyres goodyear 235 /45 /17, which seemed reasonably healthy. After having front tyres balanced for the second time, the problem refused to go away !! yesterday i consulted premier tyres, who said " simple you need new rear tyres !!! they were duly fitted, all the wheels rebalanced, and,guess what, problem is every bit as bad DOES IT SOUND LIKE SAWTOOTH ? if so what can i have done ??

Hey,
My 2018 Passat Variant (Highline) passenger door lighting trim and door handle lighting don't work. I saw it at an auto shops OBD scanner readout but I don't know what to replace. Is it expensive or should I order a car electrician to do it themselves?

I have this VW Passat that will not shift gear when parked in the sun. Every morning, the gear will change normally and can drive more than 300km as long as the ignition is not switched off.
If the ignition is off and the car is parked for 15 mins and above in the sun, the car will not change gear again until the following morning. When it is working normally, no fault code will be displayed using OBD II machine but when the gear refuses to change from 1, the fault code will display ABS /Brake Control Module with VW 01316 as its code. I need help and it's urgent.
