Hi guys, 

 

This is following on from a previous post regarding fueling issues and loss of power on my 06 Octavia vrs tfsi. It was recommended I try changing the fuel filter but that has not helped. The issue is now a lot more persistent, and I am very reluctant to drive the car as it is constantly underpowered and struggling. 

 

So far my diagnostics have led me to either replacing the low pressure fuel sensor, or the N247 valve, but I'm struggling to find any info on these parts and am hesitant to order replacements without more knowledge. 

 

I'll attach the codes below, one is a boost leak code that has persisted for a while which would also be nice to sort but not high priority.

 

Any help would be greatly appreciated.

00010 camshaft A positioner slow response

00135 fuel rail/system pressure: too low

08801 boost pressure control valve (n249) mechanical malfunction

 

 

Hopefully not a worn lobe on the camshaft.

 

00010 no idea. But rosstech says check n205 valve and wiring. 

This could be linked to the 00135 code?

 

00135 i had this code.

I replaced the low pressure fuel sensor, low pressure fuel pump and the low pressure fuel controller. In the end gave up and took it to AKS tuning. They found out straight away that it was a different fuel preasure sensor which is on the underside near the inlet manifold. A previous owner had put the wrong sensor on 200psi and not the required 140psi. Solved the problem.

A Genuine new low pressure sensor is not expensive and it isnt difficult to change so it may be a worthwhile starting point to uprate to the latest revision.

 

08801 no idea.

But if you had to change dv or pcv:

DV is cheapish but a little fiddly but easy enough.

PCV valve and gasket is slightly more expensive but really easy to change.

Thanks for the reply. Is there an easy way of checking all of these or is it just a case of buying a replacement?

Getting someone with vcds to read the codes properly and to look at the measuring blocks.

Okay, will give it a go thanks
