Hi all,
I bought the facelift gti gauges a while back as the black and yellow dials with the huge clocks wern't really doing it for me, me and my dad 'bete noir' were hoping for an easy switch over but we got the usual issue with the oil pressure buzzer. We agreed that although removing the buzzer would be a quick fix, I don't really want to be risking not having a buzzer and fingers crossed, we've discovered a fix.
The GTI has two oil pressure switches. Both of them short to earth in the engine's normal oil pressure range. If either of them is open circuit then the oil pressure warning lamp and buzzer are activated.
The 1.4 has only oil pressure switch, so when GTI gauges are fitted, the connection to the high pressure oil switch is open circuit, and the warning lamp and buzzer are activated.
To solve this, but keep the 1.4's low oil pressure warning functional, the high oil pressure switch wire has to be connected to earth. The easiest way to do this is in the loom connected into the back of the instruments. The yellow wire in this loom should be connected to the brown wire in the same loom, and this sorts the problem.
With the handbrake, we've literally just taken the warning light out as I hope to notice if the handbrake is still on.
Hope this helps and sorry if its in the wrong section.
