Guys had MAF replaced. Bosch genuine. Car seems smooth and quicker, slight delay in surge of power from previous one but smooth delivery of power, less grunt throughout gears. What can you advise?
Does it need tuning? Reset adaptive?
Why would a new sensor take time on acceleration for power? Or hesistant?
Did 100 miles on M1 last night, at one point foot flat on pedal then took delay before pier surge kicked in? Seems powerful once there but took longer than previous one in getting there
Ok thanks. What if it already has been reset? What shall I do?
Seems to be using more fuel, why is this?
Average 31 MPG on dash at 70-100MPH ish
Is a difference after replacing MAF sensor.
Is this a common issue or shall resetting adaptations resolve this?
I am concerned what other issues it may need to rectify
Please let me know to do cheap guys
Costing me a fortune already since the light started to appear.
Is the check engine light staying off? Either way, reset the adaptions. It doesn't matter if it's been done already it'll need done again.
I'd say you're pretty much sorted. If I'm cruising above 75 I'm lucky to get anywhere near 35mpg, however if I keep it between 65 & 70 I can make 40mpg.
Now that you've solved the 171 fault code problem I'd go with a good service and keep an eye on the fuel consumption.
Its strange I used to idle funny but gave more MPG before new MAF. I would have thought its the other way around?
Update; Later this eve noticed a little hissing in 4th and 5th only after 4k rev's!

Interested to see if your engine light stays off and the MAF sensor option from ECP is a way better option.
