[Big stu13]

Hi have 3 fault codes car seems to run OK but mpg has dropped a bit recently any idea and suggestions please it's not bringing engine management light up either???

Not sure about the codes, they seem quite confusing tbh.
However, if your mpg has dropped with no faults shown then first check the small ribbed pipe above the throttle body inlet.
Prone to splitting and if so it lets more air in and the ecu enriches the mixture to compensate.

I’d say your MAF is on the way out

What engine size is it ive a few in the parts bin if you want to try another?

Ah sorry re read as 3.0

You not got a spare for 3.0 Stu??

I’d check for leaks first before replacing the MAF. Could just be a split pipe taking in unmetered air.
The last code relates to throttle position sensors not reading the same. Could just be a hiccup or one could be on the way out.

I have a quick look and listen for leaks cannot seem to find one the large boot with the small corrugated pipe was only replaced last year?

Not running a cone induction kit are you?

No still standard.

Is that Carley?

Is that Carley?

Yeah it is?

 

[Rockhopper]

It just shows how poor Carley actually is - that information is so generic its almost useless. A C310+ would give more useable information for far less money.
