Good evening,
I have an ongoing issue with my Seat Leon mk3 1.6 TDI and am looking for some advice to avoid extensive garage bills.
My car intermittently loses power for around 10 minutes. This can occur at any time but on a 130 mile journey a few days ago it happened on the motorway for 10 minutes then didn't occur again. On the 130 mile return drive today it happened a number of times during the 4 hour drive, on both the motorway and on country roads at 40mph.
The car will suddenly not respond to the accelerator. Even when flat to the floor there is no response. If the road is level there is enough power to keep the current speed but not enough to accelerate. If it occurs when going uphill as it did on the M62 this evening speed will quickly bleed off resulting in me having to crawl at 26mph to the next junction. The power came back around 5 to 10 minutes later, briefly disappearing an hour later for a few minutes before being fine the rest of the way home.
When power is lacking there is no spluttering, no misfiring, it just has no power. The rev needle doesn't jump around and instead moves smoothly, slowly going down as the speed bleeds off.
On the drive out it occurred at 70mph with cruise control set. Cars suddenly appeared to be passing me and as I glanced at the dash I saw the speed dropping slowly. I disconnected cruise control and tried the accelerator and there was no response.
The glow plugs were changed last week and this issue first reared it's head months ago but then disappeared. It has since returned.
What would be the best place to start looking please? Am I right in thinking it could be a fuel pump issue or filter blockage?
Thank you
