Fault codes and limp mode

[Oily Rag]

Hello all,

I'm new to the forum and wondered if anyone has seen this problem before.

The car is a 2018 150 Leon FR 2.0 diesel.
There are 5 fault codes which are on permanently:

1. Transmission neutral position sensor - implausible signal
2. Sensor reference voltage C - open circuit
3. Sensor for internal pressure of cylinder 3 - electrical error
4. Turbo/supercharger underboost
5 Transmission neutral position sensor - electrical malfunction

The car goes into limp mode randomly, usually within a couple of miles into the journey.
We replaced the #3 glowplug sensor last week. The code for that cleared initially, but is back

The car apparently has a long history of this fault going back three years.

Any help would be much appreciated.

Thanks in advance.

Hey Raggy, I suggest you pop this on the relevant Leon section, as not all members will check out the New Members posts.
