Hi everyone, I'm new to this forum and new to Porsche but as usual it's a find a fail find a forum, sad but true.
Ok , my issue is as the title suggests, I hardly use the car and it was fine when I parked it a month ago with an optimate trickle charger connected.
Any suggestions?

Get it to an Indy or dealer and get the associated fault code read.

Flashing between 4 and D is telling you there's a tip issue.

PSM light could be a separate issue.

What year/model/mileage?
Could be something as simple as low or dirty ATF fluid - it's a service item needing changed at 10 years/90K miles on the 996.

I'd disconnect the battery for an hour to see if that clears it. Failing that you need something to read the computers error codes.

Thanks guys, I have a feeling it had an issue with the tip tronic before my ownership, this isn't the first sign I have had.
Last time when in manual mode the car seemed to cut out or not select a gear, I did a bit of research and tried the correct tyre pressure, this seemed to cure that problem. As I don't use it to often the pressures were a bit off.
Q. What effect will leaving the battery disconnected have?
I also had the air bag light come on last time I used it, my local garage had a code reader but couldn't clear it, I don't want to take it there to have it fixed would prefer an Indy to carry out any work.
It is a 99 996 C4 It has 92k on it but was rebuilt by Hartec 10k ago, the transmission isn't mentioned in any invoice from them, will check the service history to see when it was last done.

Disconnecting the battery for an hour will reset the learned memory function of the box and sometimes clears erroneous errors but this sounds a little more complicated than a simple one-off error.

Get it to a well regarded Indy and pull the codes. 911UK forum is a good resource and a post on there will give recommendations in your area.

At that age and mileage and without proof of ATF and filter change there's a fair chance it's never been carried out in its lifetime - anecdotally, there are lots of stories of this simple service curing lots of faults.
Fingers crossed it's something this simple.

Ok I'll do the battery thing first, as the car sits for long periods and there was nothing wrong when I last drove it, it might be worth a shot.
Incidentally I did a search on here and the car has come up for discussion before I purchased it, as it was on here I saw it advertised. Something to do with dealers ripping off the PO'S and selling at highly inflated prices.
The car has a very good service history and appears to have been enthusiast owned for a good deal of its life so hopefully I haven't bought a lemon.

I had to go to a specialist as disconnecting the battery didn't work.
D9 Autotech detected a faulty tiptronic switch/ sensor? Apparently a common problem, anyway after a wallet emptying full service inc brake fluid and Millars Nanotec oil, the switch/sensor replacement has cured the problem.
Just have to have the clock wire or whatever it is called replaced to get the airbag light to go off and I will be 😁
