Brief loss of power. VCDS logging fails.

[gmoorc]

I originally posted my problem in the Octavia forum but as I’ve just bought a VCDS I thought I’d have a go in here! Long post but hopefully the detail will help.

 

2005 Octavia 2.0 PD140 Diesel with a shark map

 

I've owned the car for 5 years and I think I’ve had this problem for at least the last 2 years. A blip in the power delivery of just half a second or so where it feels like the start of a stall.

When this happens the Glow plug light comes on and usually the EML which then both clear within a second.

There is also a double tick noise from the drivers dash area that sounds like a relay.

This can happen at idle (Where it would stall) or when driving.

 

Initially this would only happen in winter and just once soon after setting off in the morning. Not when driving back from work in the evening strangely.

This year the frequency has started to increase so that it has happened through the summer and now at any time, maybe 4 or 5 times in a 50 minute drive.

 

Booked it in for a diagnostic with Skoda last week but they couldn’t find anything and typically the problem didn’t occur while they had the car. Fortunately they didn’t charge me as they didn’t find anything.

 

Apart from this the car starts and runs great    

 

VCDS

 

I tried logging some data but as soon as the issue occurs, VCDS logging stops and reports errors on the log screen for each measurement (Attached)

 

Error Codes

 

Cylinders 1, 2 and 4 have the error below. Skoda and a specialist I had a scan with last year were dismissive of this.

Also this with the same single wire error on the doors although everything seems to work OK. I've had this error since getting the car.
