Golf MK5 starts and shuts off instantly?

[hussnainh8]

Hi

Please if anyone can guide me im puzzled with this car. I have a golf mk5 1.9 2005 I bought as a trade car thinking I could fix it as I assumed it needed a new ECU however this is not the case. The car will start but turn of instantly as if the immobiliser kicks in. There are no dash board lights when turning the ignition on except the MFD display which works (I can change the time).

I have already replaced the following:

ECU
Clocks
Body control module
Canbus gateway
Battery

Is there anything else I could look at or replace related to car starting but turning off instantly?

The codes I am getting are these:

18058 - Powertrain Data Bus
P1650 - 000 - Missing Message from Instrument Cluster

18045 - Powertrain Data Bus
P1637 - 000 - Missing Message from Electric Load Controller

02403- terminal 15 for interior
012 - electrical fault in circuit

Seems like from researching it could be many things?

Thank you!

Does sound like an immobiliser issue to me but electrical issues aren’t my speciality.

Maybe try get a local auto electrician out to have a look at it or someone local to you that does key coding/immobiliser coding.

My friends mk5 gti was doing the same thing as you describe last year but he was getting a key/immobiliser light coming up on the clocks. He got a guy out and it cost him £120 for a new immobiliser chip and coding

What good was your reply? I have already provided the vcds codes. Explaining the codes to me would be nice.

Does it do it with both keys?

I would pull out the cluster and check the connectors and clean where needed, maybe use some dielectric grease on the pins/connector.
