  1. Hi All, OP here. To recap, having originally thought the leak was from the axle seal, I had this replaced. It then continued to leak from a nearby area, which turned out to be the gear selector seal, which it would appear was due to the 'box being overfilled. However, I now have another leak from the same area! I've been under the car today and it's either the axle seal (again), or the clutch slave. I'm thinking clutch slave as there seemed to be a little fluid above the axle seal towards the top of the gearbox - hard to be sure as the fluid had mixed with some dust (I'm in Dubai..
  2. ....and it’s not the axle seal after all. Turns out it’s the dreaded gear selector seal. Gearbox has to come out. Not great news. Now researching rebuilds as second gear synchro is a bit weak. Makes sense to get it done whilst box is out. The mechanic had the car up on a lift and showed me some play in the gear selector mechanism. There was a drip of oil there, which I questioned if it was from the axle seal or slave cylinder. He stated it couldn’t be the slave as this will leak down the other side of the box. This is not always the case though, as seen in jpflip’s image above. He
  3. Many thanks to everyone. It was the differential or axle seal on the end.
  4. Anyone know what’s going on here? Have a small leak. Image below. Thanks!
  5. Had the refurbished pump fitted by a mechanic with autologic diagnostic equipment, which has coding functionality for porsche. Seems to have worked as I haven't seen the ABS warning since. The refurbished pump was sourced through BBA reman in UK. They sourced it from Bosch I believe, who did the refurb. It has a lifetime warranty. The replacement pump had porsche part number that ended in 58 but my pump ended 59. Still seemed to work but don't know if anything was done to it by Bosch to make it work on my car. just thought I'd follow up as a reference for anyone that has this prob
  6. It turns out my ABS pump is leaking hydraulic fluid so on speaking to the various places that rebuild these pumps, they have said it cannot be rebuilt. I have sourced both a used unit, with part number ending 63 instead of mine ending 59 (superseded part) and a brand new Bosch (porsche supplier) unit. The suppliers of the brand new unit say that it will need to be coded to the car. Does anyone know the level of coding required or is it straightforward? Now just trying to find someone that will fit it.
  7. Many thanks, JFP. Do you know if these units can be rebuilt?
  8. So, I've found that my ABS pump on my car is porsche part number 99635575559. Not many used units for sale but I have found one used unit with nearly the same number, although this one ends in 8 so one number off. The two other numbers on both of the pumps match - 0265225101 (engraved next to the porsche no.) and 0265950043 (on the sticker). They look identical. A few posts back Loren, who's given me great advice before, has advised that changing out a part for one with a lower number may not work. Do you still advise this given the new info I've given above. Not wishin
  9. Thanks. Have a feeling they have told me the newer number as this is what shows up as a replacement rather than what is actually stamped on the part. It's now at a specialist's with better diagnostic equipment
  10. Sorry for the confusing message. My part number is 99635595563 and the used replacement item is 99635595558 so I'd be replacing with a part with a lower number
  11. Right, assuming it is the pump I have found a used replacement which is also from a 2001 built 996 Turbo. Problem is the part number of the replacement is 99635595558 and my garage is using saying I need to replace with 99635595563. I asswould me these are the same part with a slightly updated part number. Do you know if it can be coded to my car? Thanks, Matt
  12. Thanks guys. I replaced the battery a few months back and alternator last year. The batt was at least the spec of the original one and possibly higher. I will get the wiring tested but it does point towards the pump. Do do you know if they can be refurbished?
