Yes. That was rattling so while it's in the garage thought might aswell get it done too.
Hasn't cost me a penny in 3 years of owning it but now all come at once.
Audi have confirmed the Mechatonics Unit has failed.
All wiring is fine and Voltages are perfect.
Unit priced at £4080 at Audi.
Booked in for Tuesday to get done.
Fingers crossed.
Getting Flywheel done at same time too
Audi have it for Diagnostics Friday morning.
Will update with what they say.
I have found a garage name Milta Engineering in Bristol , who fix Mechatronic Units for £1500 plus VAT with a 6 month warranty.
Yes I think you.are correct.
I am in Stoke on Trent.
Vehicle has been recovered to.Stoke Audi garage now. Let's see what they say.
Audi specialist garage said the Mechatronic Unit has failed. So recovered it to Audi see what they say.

Hi
I have 2014 A6 2.0 tdi S-Tronic
The gear stick is stuck in P
Dash says please engage vehicle into P or N to start...mechanic connected diagnostics to it but there is no communication to the TCM.
Ecu connection completely fine...he can read it..identify it etc but TCM not connecting
Any...
Gone from Bad to worse
The remap guy came to do the Box remap...don't know what the hell he has done...lost communication with TCM...the car won't start...
Parking brake fault..tyre pressure Fault...and please put vehicle into P or N to engage start errors are on the dash ...The gear is stuck...
Software he used is Winholes...
ECU remapped using AUTOTUNER he said...
He couldn't connect to the Gearbox using his Laptop today...it would keep saying connection to TCM lost.
He is coming back tomorrow with a different software version to see if he can connect it
2.0 tdi Ultra model
S tronic auto
Mileage 140,000 miles
Power before 190bhp
Now 225 bhp apparently.
Not sure of the Torque and or Software.
Will ask him tomorrow
The remap guy is coming tomorrow at Midday. Let's see how I get on??
The crunch is clearly heard in every gear change...going up or...
Mechanic said its either
1. Gearbox needs tuning to match the remap as its not keeping up with the engine speed after the ECU remap or
2. DMF seems like it is making a noise but not 100% sure...
So decided go with the cheaper option first of getting the gearbox tune done?
Hi. Mechanic done it with VCDS laptop connected etc.
Also did a 20 second acceleration pedal hold down.
But no difference at all.
He says either box needs a remap to match the torque of the ecu remap and the fact that dpf got opened...cleaned and put back on so no carbon build up....etc...or...
Hi. Done the box reset today.
Hold pedal down for 15 to 30 seconds with ignition on etc etc.
No difference at all.
I have just booked a gearbox map / tune so will see how I get on Sunday.
Thanks for reply.
Had s tronic box serviced by Audi 10k miles ago...so defo doesn't need a oil change.
So I should get the gearbox remapped? I think it's called a TCU Remap??
They mechanic said gearbox needs to match up with engine speed etc hence needs a remap?
