Thread: D4 Restricted Performance

My D4 is just over 1 year old, and 2 days ago developed this as its first ever fault. The warning and poor performance persisted for an entire journey home (20km), surviving an engine shutoff and restart at a traffic light. It disappeared completely during a complete vehicle shutdown and lockup, while I sifted through the User Manual (unhelpful, of course), trying a restart about 20mins later.
Dealer wanted it towed, not driven, just in case it was anything actually serious. They found a log event of insufficient turbo boost pressure. They followed the LR procedure for investigation in the event of such a fault report, and found.... nothing. Everything seems to work as it should now, and they found no leaks, faulty contacts, faulty sensors or any other malfunctions. Returned it to me within a few hours.
We'll see whether it happens again, and pray that if it does it's not at a critical time/place (e.g. climbing a mountainous trail far from nowhere, or maybe in the middle of crossing a creek).

I can't help wishing that we had not progressed vehicle technology to the point where we now drive computers connected to mechanical peripherals through a complex and mysterious system of sensors and telecoms, less familiar than black magic. I still haven't sold my D1 (Manual 300Tdi), and while my D4 was away, I found it sooo refreshing to have an all-mechanical machine responding perfectly and quickly (albeit less sophisticatedly) to my every command. In 20 years of service from new (235000km), my D1 only ever let me down 3 times, and never at a critical time, or while off road. We'll see how D4 goes in the long term...

Progress, I know. It’s a shame really we even bothered to make the motor car. Horses are far simpler, not to mention the cart.
