My RR Sport SDV6 2012 has developed a dislike of motorways.

A few weeks ago the intercooler pipe disconnected from the intercooler giving a low boost pressure warning. Tightened it back up and all has been well. However get to 70mph on the motorway and the slightest gradient or throttle pressure brings up restricted performance low turbo boost pressure. Off the motorway it seems fine.

The pipe seems very soft. Is it possible it’s just he pipe past it’s best or should I be looking for other issues.

The pipe that detached is circled red.

Thanks.

I had this dreaded issue a few years back. It ended up being a crossover pipe at the rear of the engine. It took the dealer 2 attempts to resolved the problem. 2018 Telsa MS

Thanks for the response.
Worth checking but not sure why it’s only showing the issue at motorway speeds. -----------------------------------------------
