Car is a 2010 Octavia Scout 2.0 Diesel PD. Its on 261500 miles, owned from new , always serviced when variable calls for it + oil & filter approx 1/2 way between services, on its 3rd clutch
Yesterday I did a 570 Mile drive there and back
Car faultless going, It was only about 10 miles on each journey on normal roads, the rest M5 & M6 ( Taunton to J38 truckstop in the lake district )
Returning as I got to the M5 / M6 interchange after many miles in top I went to change gear, no resistance until the pedal was about 25mm from the floor, pedal stayed down and had to pull it back up with my foot, a few more changes after that and the pedal always returned but there was still only resistance for the last 25mm. From then on I left it in top and set the cruise on 90 only slowing for roadworks and when traffic dictated it. Came off the M5 at Taunton and it was still just resistance for the last 25 mm but as I drove through the city it slowly improved and by the time I had covered about 6 miles home it had returned to normal. Today its been perfect.
Im assuming its a heat related combined with old age issue but anyone any other thoughts and more importantly is it the sign of another problem starting to develop.
Thanks in advance for any help
