PRNDS flashing - help

Hi All,

Recently the display on the dash where it shows which gear the car is in has started flashing. This only happened a couple of times over the last week but was still driving fine until this morning when I lost power whilst reversing - after turning off and back on power came back and all was fine.
Occasionally when pulling off from a stationary position the car jumps - doesn't latch into gear immediately (Ill get some revs but no power) then after a couple of seconds it will jump into first.

I've read a couple of similar threads talking about gearbox ECU issues but this was on older models. I've booked in it at a gearbox specialist next week but was just wondering if anyone can share some experiences/give me any advice on what it is it might be?

Any help would be appreciated.

(car is a 2010 Audi A3 1.4 TFSI)

Has it had oil and filter changed every 40000 miles?

I read about this and questioned it with Audi, and when I rang up the answer i got was "it's a sealed unit, the gearbox doesn't need an oil or filter change it should last a lifetime".

However I'm sure there was a recall around 38000 miles where the gearbox oil was changed but not sure about the filters (I'm at 55000 now).

Do you think it's worth checking?

there's a worldwide recall on the 7 speed s tronics on the 1.4tfsi, on my previous car i had it replaced for free.
good luck with that

Failing that, see if you can get your unit repaired - normally much cheaper than a replacement and comes with warranty, so worth considering.

Do you have any literature to back this up by any chance? A webpage or anything?

I am aware of the recall a couple of years ago whereby Audi changed the synthetic gearbox oil to mineral as there was links this could lead to loss of power. The oil in my car was changed at the time.. would I have a case for a replacement mechatronics unit from Audi because of this?

Just in case anyone was wondering, a faulty oil pump & acceptor lead to an oil leak which caused my gearbox issues/loss of power.

An expensive fix but thankfully not as expensive as a failed Mechatonic unit.

Thanks for the help!
