No Power, No Acceleration But Not Stalling...

[Jayton]

Hey all,

 

Just got the bleeding thing less than a week ago and already having problems

 

Driving into work today the first 15 miles were fine, stuck in a lot of traffic but that's nawt unusual.

I tried over taking a cyclist but couldn't! I was in 2nd doing 10/15mph and floored it but nothing happened, then the glow plug light came on so I pulled over and turned the car off.

 

Turned it over to key pos 2 and the GP light went out after a second and started her up, she drove for a few hundred yards and done the same again... at this point in holding up traffic on a busy road in the middle of Oxford So I tried again and it works again for a few hundred yards.... It happened again when at a point where I wouldn't block traffic so I decided to call my breakdown cover I have with my insurance, they couldn't find my details on their system (possibly because I'm a new customer) and couldn't confirm my address because their postcode system (GreenFlag) doesn't yet have my postcode... comon' it's been a year since the place was built!

 

They said call insurance directly and have them confirm my address with them, so I call them and their systems are DOWN

 

So after all that f@cking about I still couldn't get recovered, I tried again and she worked! I was only 2 miles down the road from my work so I drove there where she is now parked up.

 

So when this happens...

 

1.) No Acceleration.

2.) GP light comes on after a few seconds of this and starts flashing.

3.) Rev counter is just above 1k when this happens.

4.) The car will pull itself along as if you have released the clutch and applying no acceleration.

5.) Plenty of fuel.

 

Any ideas where to start looking? I don't have a fault code reader or cable for vag-com yet.

Not too sure about the flashing Glow Plug light, but it could be a dicky footbrake switch.

TPS - throttle position sensor - also known as the accelerator pedal position sensor.

 

Its a fly by wire system and when the dual track potentiometer attached to the accelerator pedal plays up, this is what happens. A new one costs around

Took it out this morning, cleaned up the contacts for the plug, unscrewed the first cover and cleaned both the bushes and contacts inside. Rebuilt it and took it for a run down the road and back, it was OK so took it for a longer run and seems OK so far. I think I might get another one for when it does eventually fail, at least I'll have one ready to go in!

 

Thanks for you help all ! B)

Argh! it happened again this evening 100 yards from my road :D

 

Took it apart and bent the little metal brushes up a bit, rebuilt and fitted it and it drove 5 miles to my mums. I think I'm off to get another tomorrow.

 

I assume I can get one from VW/Seat or Ford being the MK2 1.9TD?

Phone around for the most competitive price (haggle or pricematch). GSF does the part considerably cheaper IIRC (

[Jayton]

Ah yes, I keep forgetting because the parts are also used on VW's GSF would have them :D

[Jayton]

You don't by chance know the GSF part number do you? I just called GSF Reading and they said they don't have them after searching their system :D
