As the title says I received the 305hp tune by Litchfield on Tuesday (14th) and then driving home from work on the (16th) I got an Engine failure hazard warning. The car crawled to my house, luckily just round to corner from where the error happened.

I've spoken to Litchfield, and they can't look at it until the 1st of March. I got a local garage to check for an error code but couldn’t find anything.
I’ve been testing it locally and no issues. Even pushed it a bit to see but still nothing. It still has a year on its warranty.

I’m looking for a bit of advice what to do? Litchfield have said they’ve never had issues with the Alpine tune and it seems a few people have had the Engine failure hazard before without any mods. Should I get the tune removed and then go to Alpine with the error. Looks like it’s something to do with the fuel pump.

Annoyingly I’ve got a Scotland Road trip planned at the start of April. biggrin

It happened again, this time I managed to film it. Wasn't pushing at all. Pulled away from the lights, doing about 50 then the error came on. Check the video here: https://drive.google.com/file/d/148k82lPxB9QcnDEtJ...

Restarted the car and pushes a bunch to try and see it again but nothing.

Any ideas?

So, the fuel pump shouldn't be the issue. I forgot it was replaced in Nov under warranty.

I plugged in my trickle charger and found this:



It seems the battery might have been the issue. Plugged the charger in and it started at number 3, number 4 in ready to use. Hopefully this is the issue, it's no fully charged.

That fact that there's no stored error code and it tells me to check eveything makes me think it's the battery. But we'll see.

I'm driving to the lake district this weekend. Putting a few hundred miles in. We'll see if it happens again.

Okay so, 500 miles in the last week and no issues.

Of course, it may still happen but I’m more confident it was the low battery causing the issue.

My fuel pump was replaced less than 6 months ago under warranty.

The fact the error didn’t occur during fast driving makes me think it wasn’t the map. Last time it happened was 150 miles from the original error.
If it happens again I’ll take it back and remove the map but for now (Hopefully) I found the issue.
