As an IT worker I am frequently presented with 'how long is a bit of string'-type questions. Not looking for any smoking-gun answers, but any opinion on root cause and remediation is welcome!
I have an '04 GT V6. It has had stacks of work done and has had a completely problem-free year.
Long stretch of road, bright sunny day, know the area well, what can I say? - I was already at reasonably high revs in 4th and made a poor decision to give it more beans in 3rd. The vehicle did not take this well. I can't remember the exact series of events, but I immediately got the motor control failure light. Not seen that since I had a 147
Car seemed fine but quietly turned itself off when I slowed down to take a junction. It got me home after that, but on the motorway it beeped at me again and gave a 'low voltage'-type error.
A few days later and the car is ... broken. ECU code is P0100 / mass airflow circuit failure. The engine won't stay running for more than a minute or so before it dies, so driving it to the nearest garage was a colourful experience at best. Did I mention I'm not much of a hands-dirty type of IT-working Alfa-owner?
So, the facts:
- P0100 / mass airflow failure
- The garage couldn't read the code, even though I did using a cheap reader and Torque app...
- The garage also says they had trouble keeping the car idling, even with the MAF disconnected.
- I am getting the other MAF symptom: the fuel gauge works on MAR, but stops working when the engine is started. The trip / MPG computer isn't working either. I've read that these are very typical symptoms of MAF failure.
- The garage indicated I should get an electrician. I did, and it was a very difficult experience. Thought he was going to work out if I do just need a new sensor, or if I have something more elaborate (wiring, ecu...). He didn't do any of those things - he read the fault code (the one I already told him about), said he wanted to trailer the car somewhere else, then hoofed me for seventy quid before driving off into the distance with my money. Robbed!
The garage has agreed to check the MAF circuit / pipes / check voltage on the MAF, but a local Alfa specialist also mentioned I might need an electrician. I'm off on holiday today, MOT is imminent, and I have a car that doesn't behave when I try and use it.
Any similar experiences, or any thoughts on how I broke it?
