Balls + membership renewal for another year possibly. Ah well, all for good reasons I'm sure. For the immo side I'll try to limit the cost the best I can... just so I can afford a new carpet + insulation. Hopefully one that is dry and without the nasty bronze/rust color from the seat rails and the black & red dye my dearest aftermarket carpets left us :/

The ONLY way to fix that is to desolder the relays, clean it up thoroughly (soap and water with a brush is good), dry it and repair the damage. That may include replacing relays. I would also replace the electrolytic cap any time the immobilizer gets wet.

Steve - was removing those relays supposed to be fun?

Geez those NEC were almost impossible to kick off that PCB. I've never really had to remove many components during my past years as a janitor... mostly prefer trowing the whole thing (and pcb) in the garbage and starting from scratch lolll In the case of a Porsche immo... guess we can't escape this mess :/

Really worth changing the cap you think? Test meter set at 20k and its not rolling up much, dies at 15ohm then goes back to zero... fried?! Obviously going for NEW parts so I've already ordered both the Siemens and NEC sets of relays. And a cap, apparently. Anything else while at it?

Why all this??? Cuz Porsche kindly refused to reprog a second-hand immo my indy found for me. Said it will never work. Now looking for the same P/N eeproom kit around here. If we can't find that I don't think I'll bother you, or add to your already busy schedule I'm sure, I'll just get the real deal at P and call it a day instead (a $1,740 day!).

Let's try your tips first! Please save my car, and my wallet, Steve





^ Still good for a few extra thousand miles, right?

Sending a PM. I have a few ideas for you.

Hey guys, really great read on this thread.

Rebuilding these units is difficult even for our techs because they were built "fragile" and components are so close together.

Most units are not even worth the work and therefore need replacement.

Definitely keep your rain drains clean!!

Fragile; yes indeed. Needs to be done by a professional If you've never done that kind of work before, rest assured some of the traces or vias are going to snap off.

Thanks for joining in Doc. For your tech team... they need to buy My China Super Duper eyewear kit. There is roughly 1.5 kilometers between each pins/components when working under it. Which actually makes you work 1.5x slower as you move from pins-2-pins though LOLL Cheap cheap... $200

Hard work man :/
