52000 miles, Euro 6, 150. All new filters (air, pollen, oil and fuel) last year. 
Kept on driveway and no Le&Ks. Petrol Fiat used for local journeys.

Last week, this warning light continued to show after starting.
Monday, local independent (we have used for 20+ years) found 4 fault codes.
P13D600 - Sensor for internal pressure of cylinder 3 implausible signal
P2B8300 - Charge air cooler pump 'A' over speed/air in system
P67400 - Cylinder 4 glow plug circuit
P16C600 - Heater support pump dry running

Codes cleared, all levels checked, road tested, no reoccurrence.
Tuesday morning, 35 miles to Brighton, no reoccurrence.
Parked all day and on starting, to return home, warning light reappears and stays on.

No changes to tick-over speed, performance or fuel economy. However, unaware of recent regeneration.

Today, Wednesday, warning light stays on after starting.

Independent to review fault codes again next week but meanwhile, "What does the Team think?"

Thank you.

What is 'Petrol flat' is it a typo?

 

Is this about a 2.0 TSI. 

I had that with a faulty abs sensor, couldn't id the problem then some kind soul suggested it was a possibility, and indeed it was, front o/s. replaced with an expensive Bosch sensor, the cheap ones had different internal resistance readings --  no probs since!

Hi

 

The symbol you show is variously described as the Malfunction Indicator, Check Engine Light and Emissions Light.  I believe this is partly a European legislative requirement to indicate that a fault may be making the emissions higher than they should be.  Depending on the fault severity, you may also have restricted power mode to avoid engine damage, but it doesn't sound as though you have. So your fault may or may not be directly associated with the exhaust and catalyst etc.

 

It's a bit odd to get multiple fault codes which have no apparent connection to each other, but fault codes are only a guide/starting point to full diagnosis.  With the right equipment it should also be possible to read the state of other parameters at the exact time the fault code was stored - this can sometimes aid diagnosis.

I had that check engine light come up when number 3 glow plug failed.

Thank you everyone for your suggestions (indeed, Fiat 500 for local journeys)

Will see what revisit to garage throws up on Monday
