Unusual Electrical Problem. Help !
« on: 07 October 2024, 11:46 »
I  have a 2009 Golf Plus 1.4 GTI. The instrument cluster ( dash ) lights up correctly with everything working on first quarter turn of the key, but then has a complete power failure about 1 second after starting the engine. The engine starts ok and all other electrics are working. Bizarrely the instrument cluster lights up for about 1/2 second when I turn the blower on.
The battery is fairly new and I have just replaced all the fuses.
Has anyone got any ideas on what to try next?

I have heard before that this can be caused by a fault with the main light switch.  If you know someone else with a similar car, I believe they can be removed without any tools - maybe just turned in a specific way to release them.  Is worth a test.
On order: Golf GTI 8.5. Pure white/black, pan roof, Queenstown, DCC, HK, Area view, spare wheel

Current: 2018 Golf GTI 7.5 performance pack with standard spec

Gone: 2016 Golf GTE 7

Thanks for that. I’ve just checked that out. No change.

Had something similar on my mk6 that affected the radio. This required a new ignition switch. Switch bolts are one use only.
Mk6 GTI Carbon Grey, 2010 Bluetooth and voice fitted, a few VCDS mods still a comfortable family car. Red Scirocco 2011 twin charger stage 1 - enjoyable drive now gone.  White 2016 Polo GTI (roller skate on steroids) replaced with an Indium Grey 2019 7.5 GTI PP.
