Just driving along and a 'curly' light came on in the revometer.

I checked the little book in the glove box and it appeared to be the 'glow plugs'. On a second look, it seems to be something to do with the engine management system.

Does anyone have any ideas what could have caused this [?][?]

Is it flashing or constant ?

Either way something is wrong [no brainer]

You need to get it checked for faults with Vag.com or by VW

A long shot here, if it's flashing (the 'curly' light that is LOL ) ? .... are you brake lights working ?

As said above, get the bulbs from the stealer. They seem to be better quality and usually last longer.

Strange but true [:)]

I think stop lamps are 21w - no alternatives there, but tail lamps are available in 5w or 10w. I use the 10w.

mine did it when both both bulbs fused. The LED high level brake light was still working although it did have two of the outer LEDs permantly on all the time, really weird but once the bulbs were replaced everythin was back 2 normal. Have noticed other golfs like this afterwards.

HE HE HE ..... Looks like that long shot was a GOOD shot !!!

Defo Brake light switch. You need to remove the lower trim by the pedals to get at it.

Get a new one, as said about 5-6 quid.

BUT

Be very careful fitting it !!

You can easily ruin it and its not that obvious how to fit.

Pay careful attention to how the existing one comes out.

You owe me a beer !

Reason the engine management light flashes (or glowplug on tdi) is that it's Drive by Wire. The brake light switch is of a duel circuit type and is a safety feature built in on DBW cars. It basically cuts engine power etc if the throttle position sensor / throttle goes wrong.

Had mine flash twice now.

1st time I just had to change the bulbs as they were blown, the 2nd time I had to change the brake light switch.

Steve - The switch is underneath the brake pedal, it just twists and pulls out, although you may need to take out a piece of plastic in the footwell, its only a few screws though.[;)][;)]
