I bought a pair of electric M Sports heated seats from a forum member in January. I’ve had them fitted and have to say they’re in excellent condition, and give great support on spirited drives – way more comfortable than the standard seats.
Although the seats have the heated elements, my face-lift Zed isn’t pre-wired for heated seats, and so began the search for wiring looms and a centre console with additional switches. I managed to find a centre console fairly easily on eBay, but the wiring looms were a different matter! BMW no longer sell retrofit looms for the facelift Z4, and I found it impossible to source second hand ones from breakers
Forum to the rescue: I am greatly indebted to Fishy Dave who was also looking to retrofit heated seats to his M roady. He researched the discontinued Z4 retrofit looms and matched them to BMW X3 retrofit looms, which he then sourced from the States - he even labelled them up for me and posted them on (full story here http://www.z4-forum.com/forum/viewtopic.php?f=2&t=83970 ). Also a big thanks to Mr PT for providing the Z4 retrofit instructions
My Zed is booked in at my Indy’s tomorrow. I will give the garage the retrofit instructions together with the labelled up X3 looms and the new centre console – I’ve already discussed the job with the mechanic who’s going to attempt it. The key to whether this works is the retrofit looms from the X3: It looks like they have all the correct cables and pin connections, but we won’t know until they are physically wired into the Zed.
So its fingers and toes crossed
