A few months ago my car started consuming around half a liter more of diesel on a regular basis. I thought maybe it was the winter weather, but the winter was very mild here in the end. Now the temperature is usually pretty high, as we are approaching spring, so I'm having a hard time finding temperature the problem.

I waited to see how the car will behave after doing a yearly service - oil change, new oil filter, fuel filter, air filter and also changed the timing chain oil tensioner because

Hi everyone I am getting the following error code P0006 using an obd scanner and the code relates to Fuel Shutoff Valve A Ctrl Circ Low
is this something that is easily fixed I have noticed the the car seams to miss fire and I have seen an increase in the fuel consumption. 

Dear All,

I have a couple of very recent issues with my 63 plate GTC 1.4 t and wonder if anyone can give me some advice.

One relates to the ABS warning light and traction control light illuminating on the dashboard together with an ESP service warning message on the trip computer. I think this might be a sensor issue somewhere.

The vehicle is running ok (ie no misfires, slightly slow pulling away like in a very slight limp mode when it gets to 2000 revs).

Is this an easy fix or somet

Hey guys, I am a new user of a used Astra 1.7 CDTI 2011 and I've been told by some people around that this car is very sensitive to fuel quality.
Now the problem is that in my country fuel quality is the worst, there's absolutely no assurance of the quality no matter where you try to get the fuel around here, and chances are that the kind of diesel we have is just slightly better than the one your country uses only for agricultural vehicles.
Is there anything I can do to make it less of a prob

I recently had my fuel tank replaced due to a hole in the pipe s, since it’s been replaced I need to prime my fuel pump every time I start the car or it will just turn over for what seems like ages!

Is there any way of fixing this??

Hi Guys
My Vauxhall Astra J 1.7cdti, Hatchback, 5 Door, 2011 61Reg.

My Diesel Fuel Gauge is was showing few days a Low in fuel and then after a bit showing half tank and then again low fuel.

However on the same day in the evening i just filled in £20 worth of fuel just to be on the safe side, but since then i have driven 1.5 miles, but not noticed the error of the low fuel.

What could it be is it the Pump, Float Valve or the Sender Unit ?
