  1. You can actually use hot water and a good cleaner/degreaser with a toothbrush to clean the boards. I do it all the time. Chances are these boards were cleaned with water after assembly, and _most_ components are designed to be cleaned. The exception is some electrolytic capacitors and non-sealed electro-mechanical devices like relays. Don't be afraid to scrub fairly aggressively and just be careful to make sure that it is thoroughly dry before you apply power again. The key is to get all of the metal salt deposits and mold off, as that is what is conductive and will cause erratic behavior
  2. Yes, it is nice when people can afford to share all their knowledge. Someone may even share this information. You could also look at from the point of view that if I didn't charge for my services, but just shared everything I learned with the world, then I wouldn't be able to afford to buy the education and thousands of dollars of equipment that I have that has allowed me to do what I do. Catch 22. If I was somehow magically wealthy I could share LOTS of trade secrets. In the past I have shared more than I do now. I have also been burned more than once by people that took knowled
  3. Well, no offense, but I consider that proprietary information that took me a bit to figure out. This is how I pay my bills, so I don't tend to give out that information so others can profit from it. I can say that I have done it twice now, on my car and a 996 Cabriolet that got wet. A used module and an hour of my labor is a lot less expensive than a new module, programming and possibly keys from a dealer.
  4. Not true, my module was pretty much trash. The module had been sitting wet for weeks, then a new battery was installed by the previous owner backwards which did more damage. I didn't use the factory tools to read the information. I got it directly out of the ICs on the board, which, in my experience, rarely get damaged. I did not need the programming codes. In fact, I didn't even connect diagnostics to the car for a couple weeks after I got it running. I just got the programming codes for my car a couple of weeks ago. I will say that this is what I do. I have been designing, bu
  5. I am a little late to this, but it is possible to transfer the data from the old damaged alarm module to another used or new alarm module. BTDT with mine. When I got my car the alarm module had been severely water damaged. I found a used alarm module of the same part number, and transferred the data from the damaged alarm module to the used one. The nice thing was that the module was cheap as the seller did not have matching keys or ECU.
  6. I am doing something similar. I have a set of black leather door panels, in excellent shape, and want to swap some of the leather with black Alcantara. The method that I have seen to separate the panels is by heating the "rivets" with a hot air plastic welder with the appropriate sized nozzle and prying them appart. Done carefully, it should go back together somewhat easily. At least that is my hope...
  7. I repaired Matt's cluster, tested it in another 996T here, and it is now on its way back to Dubai. Matt should have it back in the next few days. It took a bit longer to turn around as I was on vacation when the local 996T was available to test it in, but it turned out well. I don't like shipping things half way around the world without being able to test them completely. I can test everything BUT the oil level circuitry in my '03 986 S, as that circuit is a bit different due to the different oiling system on the M96. This does seem to be a common problem with the 986/996 clusters, at
  8. I have had good success repairing these '01+ clusters. In the last few months I have repair three 996TT and a few 986 clusters with oil measurement issues. The oil measurement circuitry is very susceptible to damage from over or reverse voltage problems. Fortunately, these are repairable and repair cost is generally far less than a used replacement cluster, especially if you factor in getting the odometer reset, etc.
  9. The thing is, if you have a bad connection the needles usually pegs, as the resistance of the sender goes up with pressure. If the sender fails internally it could read low, but a poor connection will make it read high. There are two wires to the sender. One is the gauge signal (variable resistance), the other is the oil pressure switch (on or off) for the low oil pressure warning.
  10. Well, that wasn't actually my intent, but I do think I could handle that if you would like. PM me and we can discuss.
  11. Yes, that would be good. Just code it for km, zero the odo, and swap the main board into your cluster. You just need to remove a few torx screws, and undo three connectors to separate the main PCB from the front PCB that has the gauges. Then sell me your old cluster! :) Alternately, you could check ebay.de and see if you can find a turbo cluster that is already has the speedo in km.
  12. The hardware is the same on the different late 9x6 clusters (with dot matrix OBC), so you could theoretically put a 986 Boxster cluster in a turbo. The problem is that proper cluster for your car will have the speed in km/hr, the correct speed range, the right color gauge faces, etc. Each combination has its own part number. The only one that will be an exact match for your car is that part number. Others will work, but you will have to deal with whatever difference in display, etc. that cluster has. The easiest solution from my point of view would be to fix the existing cluster. Then th
  13. I'm jumping into this a bit late, but I have now repaired a few 9x6 clusters with issues with the oil level sensor circuitry. In my experience on these though the oil level test would generally generate faults and not run the level test (996T), or be very inaccurate. That would usually be consistent. There were difference on the symptoms on the dot matrix center LCD on cars with OBC clusters (like the 996T) or with the standard display (most 996 and 986). I wouldn't doubt the issue is in the cluster, as that circuitry is particularly susceptible to problems resulting from jump starts, etc.
