I have done over 300 miles today in my 2002 Aero and had an odd problem a few times
First of all it happened while I was down to my last 50 miles in the tank and the car sputtered a couple of times, the pretend boost gauge also dropped as the car slowed even though my foot was quite hard down.
I refilled the tank ( £100 :o ) and drove off thinking maybe it was fuel starvation.
It was fine for a couple of hours and then it happened again while I was overtaking and pushing hard.
I backed off for a couple of miles and when I pushed again it was fine.
I have a bolt in the 3rd hole of the APC valve, the throttle body is only a couple of months old aswell as the DCI pack. Plugs and fuel filter were done 1500 miles ago.
Any ideas?
My Turbo does puff on start up some mornings, could it be that letting go?
Thanks
Steve
Can you engage the cruise control when this happens? If not it could be a problem with the cruise control brake pedal switch. If it sticks and the car thinks that you are braking, the boost will be cut. Could also be the brake light switch itself doing the same thing.
Or a badly inserted brake light bulb. They can be pushed in too far and the twin filaments can short between the tail light circuit and the brake light circuit/ This can cause many strange effects as it confuses the electrics....
Just one thing to eliminate before you think the worst.
Thanks
I have not tried as usually when it happens I am not in a cruise situation. It normally happens while overtaking or going uphill.
I will try next time it happens but of course it has not happened since Monday.
