No power, no revs
« on: 13 January 2010, 12:10 »
Hey all,

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

It's a 2000 X reg Galaxy using a 1.9TDI PD, so still relevant  :smiley:

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  :embarassed: 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  :angry:

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?  :huh: I don't have a fault code reader or cable for vag-com yet.

Get yourself a fault reader from eBay Jay.

Have you tried unplugging the MAF sensor and tried her then?

I'll give that a go in a bit. Just been back out and it did the same thing first time I started it, shut it down, started again and it was revving freely for a few minutes, shut it down again, and it did the same thing after a few revs  :sad:

Someone else mentioned wastegate or throttle potentiometer (although they did not have the whole story), how likely are these?

Don't know haven't got a clue.

Check the MAF first mate, it's plug by the airbox and see how you get on!

Looks like TC (Diamond Hell) might have been right about the throttle potentiometer.

Fingers crossed it sorts it.

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 £60-£80 IIRC. Pretty easy to change.

Do a search for more info - people have stripped the sensor down and cleaned out the fluff and restored it to working condition.

It sounds like someone has put petrol in it.

Does it smoke at all?
