The IAT sensor is part of the MAF sensor, if that cured the temperature issue then you probably have 2 faults. Unless the original fault wasn’t cleared in the log of course. But I’m sure that’s not the case.Quote:

The ECU remapping guy came yesterday morning, he updated the ECU and cleared the code off the ECU, he said all the parts working fine in the car, just need to update the ECU and clear code using the Remapping tool, which the garage and auto electrician don't have this kind of tool, I have done a 30 miles motorway last night and another 30 miles this morning, so far no lights, I think he might have solved the problem. I think perhaps the ECU of the A1 is very sensitive, it needs to be updated after new sensors fitted, but anyway, I am happy the problem has been solved, I will give it 2 more days to monitor the light, hopefully I don't need to do anything any more.Quote:

In that case the fault was the MAF/IAT sensor as the 130C disappeared when it was changed.
Sounds like a result !
When you say he updated the ECU what did he update it to?
Hope it stays fixed.
[QUOTE=Muckie1;1091012]Hi Matt,
Same symptoms by the sound of it.
Did you run VCDS on it?
Take a look at mine earlier in the thread, I had IAT at 130C, do you have this too?
Let me know what IAT temp is, that is key.
Also, out of interest does your fuel cap lock work? Lock the car and push open the fuel cap cover.
Let me know what you get.

Hi I’m suffering with the same problem . Just wondering why have you asked a question about fuel cap locking?? Is it related to issue wit bad maf senor?? Thank you very much
Do you have a faulty MAF?
It was really strange, VCDS was showing the fuel cap lock as a short circuit to ground.
It may have been a coincidence, but when the Boost pressure sensor was changed the fuel cap lock was also fixed and has been ok ever since.
VCDS showed the following
1 Fault Found:
00332 - Control Circuit for Tank Flap
007 - Short to Ground
Hi Muckie i have the same problem with my daughters 2014 a1 1.6 diesel any help would be appreciated
Have you run VCDS? What codes do you see?Quote:

Boost pressure sensor was faulty, but there were odd symptoms along the way.
Have a look at thread.
Old thread but interested to hear about this and the eventual cure.........if anybody still active on the forum.Quote:

Code every time is MAF p0101 after a glow plug light sometimes and occasionally the MIL light on.
