Hey all new owner here from the states. 

Just received my RS FOUR S last week. Went to replace some interior bulbs with LEDs this morning and after changing the first map light bulb I lost all lights to the map lights in front of the rear view mirror, middle dome light, rear trunk light and also the ring light around the ignition. They do not work manually, when the keyless entry is used or when you open the door.

 

Everything else is still functioning like the head lights, fog lights, cluster, radio etc.

I tried replacing the LEDs with the original bulbs but no luck.

 

I replaced every fuse in the under dash fuse box to be safe, most looked original but none busted. While changing the fuses I noticed the TCM box was loose and could wiggle it around. Not sure if it's related or I just shorted something out while replacing the bulbs. I foolishly did not disconnect the battery prior.

 

At a loss here, couldn't find any similar cases to mine. I will try to check for continuity tomorrow as a last resort.

 

Any advice is much appreciated. Thanks in advance.

If you're not good with a multimeter, take it to an auto-electrician. There's no way that we're going to be able to guess what you've done wrong from the other end of the inter-pipes, and it's going to take diagnosis effort to find out.

    • I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to come I’ve seen though 
    • $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.
    • Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.
    • I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.
    • I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
