Hello all,
Some of you may have seen my post in 'Introductions' about S8YOT's old S8 which I bought last night.
Well it's done 183K, had an oil change at 100K and has died within the last 500 miles or so.
From what S8YOT told me, it left him working well.
The dealer I bought it from had sold the car to someone else and on the delivery drive (by a now jobless delivery driver!), the gearbox let go and now has the follow problems.
Put it in D, you try to set off and nothing happens.. then BANG! and you're in. Then you're not and then it goes into Limp mode.
Once on the move, you can clear the faults and if you're at a speed which would be in 5th, it works fine and is happy. However, if you boot it and it drops to 3rd, you're into problems again.
There were two fault codes on it when I first plugged in:
17116 - Gear 2, P0732 - 35 - 00 - Incorrect Ratio
17114 - Gear Ratio Monitoring, P0730 - 35 - 00 Incorrect Ratio
After each time it went into Limp mode, only 17114 came back.
I've done a small bit of research regarding the ZF 5HP24 and in all the vehicles that it was fitted to, it has problems!
I bought the car with the intention of breaking it and running the engine in one of my projects.. this may still happen but I want to get it working fully again first.
I'm going to look into carrying out the repairs myself. I'm a Porsche trained technician who has also worked for Audi/VW specialists so know my way around a car. The only areas I've never gone into are Auto Transmissions. I rebuild my own manual gearboxes and have all the associated tools for that.
Because there are so many problems with the ZF 5HP24, the issues are well documented along with fixes.
This will be one interesting and steep learning curve
The biggest issue I have at present is finding somewhere to take the gearbox out and then store the car while I fix it.
