Induction pipe "Sucks"
Got a warning "Ping"and a "Motor Control System Failure" message whilst traversing the last few roundabouts exiting M Keynes on Saturday following a session of playing with model boats at Willen Lake. Fortunately, engine behaving it self with no signs of any major issues.
On purchasing my Blackline JTS GT last October, (From A Jag main dealer) I was aware that there was insulation tape around a section of the moulded "Egg Box" rubber induction pipe in the area that looks like a joint but isn`t. Inspection on Saturday showed that the tape had shrunk or lost a wrap as there was adhesive in evidence either side of the tape in situ that may have been applied to seal a split. Upon further inspection today, prior to getting car booked in, I discovered that by gently pushing / easing on the pipe, about two inches away from the existing tape area, a split opened up for about a quarter of the circumference of the pipe. Upon taking hands away the split completely disappeared partly due to being masked by the raised rib running the circumference of the pipe. I am assuming that air is being drawn in here plus air from the taped section as well!!
Subject to hooking up and expert opinions of my nearly local indie the fault should lie with the pipe that will be replaced in any event. The only signs that I have had that something might have been a bit amiss was that if stuck in stop start traffic the revs were slow to drop back down to 900rpm on tick-over with foot off the throttle from say about 1,500rpm when moving. I have been getting about 35mpg on countryside runs (50 mile round trips) but with a bit of town, traffic delays and roundabouts to holding it back to this figure.
I post this in case it helps others or if anyone wants to pass comment.
