Thread: 2011 D4 'Gearbox Fault' warning

Hopefully this is not too pre-emptive but I chickened out on replacing the TC and had the pros take care of it. We settled on a house we bought last week so my DIY-ness is being sucked out of me for the next few weeks.

I picked the car up yesterday. Holy mackrel, it's smoooooth. EV smooth in fact. Advice was that only the TC needed to be rebuilt and that the rest of the transmission didn't need attention at this point. I've been going out of my way to drive all of the local spots that would send the tacho needle into a frenzy. It's so satisfying to see it behaving itself coasting and under load.

So, collectively you guys were right from the very beginning of this thread; 2 issues - the HPFP and transmission, specifically VB, solenoids and TC. That's pretty amazing. What a journey.

Ha - yes indeed on both accounts. Loving driving it again, not loving the 'wonder what next' feeling.

$2,900 for the rebuild. Steeper than I was hoping but a good investment in time - I reckon I bought myself 3 weekends at least.
