Front-end Upgrade: Simple Electrical Question

[jamesevelynclarke]

Hi,

Conversion from standard Cayenne S front bumper and lighting to GTS/Turbo look almost complete and has been very straightforward so far (will post conversion once complete).

Only outstanding question is about the daytime running lights. In the S the bulb is a 5W5 (12 Volt, 5 Watt). I had thought the GTS/Turbo light was LED but is in fact just a simple bulb (a straight version of the BMW `angel eyes' lights used in their X5). However, it is a 12V, 2W rated item.

Question: If I simply take the existing feed from the 5W5 bulb and connect it to the 12V, 2W new bulb, what will happen? In theory I think it would work and just draw a lower current but this might trigger a `blown bulb' warning in the dashboard? Is this right?

Tks

You are correct. There is a coding setting for the LED bulbs in the PIWIS.

What about wiring housing? you have ordered new front wiring from Porsche or just order the wiring housing from VW Touareg?

Latest installment: I took the feed from from the standard running light bulb and just connected it to the new GTS running light unit. The strip light comes on fine and the `bulb blown' warning message does not appear. The only issue is how to make the connection to the new unit permanent. I asked the local Porsche dealer and they did not have the square connector block required (as shown in your photo) as it is part of the whole wiring loom. I wasn't aware that the connector was a standard VW Toureg item??

Anyway, I am instead making my own connections, which are quite straightforward and will post some photos in a couple of days.

The indicator bulb connection in the GTS light unit is exactly the same as on the S so this is a simple plug-in.

Tommorrow is the big job when I remove the front bumper and try to put on the replacement GTS/Turbo unit. This will also involve putting on the front wheel-arch extensions. My car had these fitted as standard as it has the 21" sport design wheels. The extensions seem to be simply stuck onto the bumper with double-sided automotive tape! I guess I will just need to gently prise them off mine and replace on the new bumper with fresh tape.

The last thing then will be to find caps for the headlamp wash holes in the new bumper. My car does not have the xenon lights or headlamp wash. I had bought some caps (955 628 301 11) but these were for a Cayenne S model and it seems that the holes in the Turbo/GTS bumper are specific to that model so I will have to try again.

You need the caps for GTS/Turbos:
