Low Fuel Causing Engine Management Light

Hi Everyone,

First post on here, but had my 992.1 Carrera T for 15 months now, been meaning to ask this question, but with my cars first service coming up it's prompted me to ask.

What are people's experience of the competency of Porsche centre mechanics?

I bought my 992.1 Carrera T as a life long ambition to get a 911, never owned a Porsche before but always a passionate fan. It was 6 months old and 872 miles on the clock. I picked it up on a Friday afternoon, planned a drive out on the Saturday morning and within 15mins of driving the engine management light came on. I was advised to drive it back to Porsche Bolton, who fair play checked it over there and then. Apparently a fuel pressure fault and the front air intake vanes stuck in position. Faults cleared, told it should be okay now.

Next day on the Sunday afternoon, engine management light comes back on. Phone them the Monday, and take it back to them on the Wednesday. I was provided a Carrera T demonstrator for the time being. I was told it was the intake vanes stuck again, so new vanes delivered, fitted, sorted.

I picked it back up again, next day, engine management light back on... They collect the car from my work, swap for the same demo Carrera T. I ended up doing over a thousand miles in the loan car. Over a week back in the garage, I got called to say I can pick it back up again, here is what the diagnosis was...

"Don't let it go below 50miles range, it's a common issue that if you do, the engine management light can come on"

For obvious reasons I refuse to pick it up and explained that firstly, it wasn't below 50miles range when the light came on. But secondly what is the point in a low fuel warning if the engine management light comes on first? And thirdly, unacceptable.

They were adamant this was the issue, but I refused to pick it up until they had a valid diagnosis. Another week later, further diagnosis, they found that the fuel pump was intermittently giving out high fuel pressure, and they thought this was triggering it. Fuel pump swapped for a new one, picked it up, never had a problem since.

I questioned if it had this issue prior, the fact they believe it a valid reason to not let it go low on fuel? Why was it 6 months old and 872 miles, perhaps the previous owner had this issue and got fed up? The fact that the issue arose the day after I picked it up, and consistently reappeared, suggested so.

So, has anybody else been told by a Porsche dealer that their 992 engine management light is coming in because of letting it go low on fuel? Curious as to how many people are topping their fuel up to try and prevent this issue.

I found it completely unacceptable. I fear that if it wasn't that I'm an engineer by trade, their excuse could have passed me by. Likewise, coming up to my cars first service I am highly dubious of the competency of Porsche mechanics now.

Appreciate any thoughts on this matter.

James
