Hi,

I've searched online on various forums but haven't found any relevant info so here goes;

A 2014 (64) Superb 2.0 TDI 140 has a fault when starting doesn't matter whether hot or cold but the car will fire up and then immediately cut out. Sometimes it can take 4 or 5 attempts to get it run longer than a split second. 

There are no fault codes present.

Has anyone had any similar issues?

Thanks 

Sounds like it might be a fault in the immobiliser. If it can't verify that an authorised key is being used it will start and run very briefly then shut down.

 

Does this happen with the second key?

Thanks for the reply. I'm just running the 2nd key now as I suspected exactly this. Will see how it goes over the coming days

@adi69
Might sound stupid but has the timing belt been done recently?

As I had something similar

It was the correlation of top cam to crank that was off shutting down engine😕

Due to my "mate" doing the job quickly (wrongly)

Thanks for the idea but the timing belt is due for renewal next month so as yet no it hasn't been done. 

 

An update though, the 2nd key has been used all week and it is still doing it. Works fine for a period of time, then bosh, fires then cuts out straight away

Sounds like the coil in the ignition barrel might be gone? At this stage I'd be getting some diagnostics done to try and chase down the source of the problem.

Good shout that 👍 had laptop plugged in before anything else and unfortunately no codes to start with

Immobiliser faults will show up on the instrument panel or immobiliser ecus.

Again thanks for the info. How do you get to the faults on the instrument panel?

 

I'm guessing on vcds there will be a separate setting to get into the BCM or immobiliser ECU?
