EML warning light revealed P06DA00, cost to repair this?

[rayasun]

What is the cost associated with P06DA00? My car is showing this error along with P012800. Thanks in advance.

Why not ask the garage that looks after your vehicle(s)?

Costs can vary significantly depending on where in the UK yuu6are, if you use a main dealer or Independent etc.

You also haven't stated what vehicle you are referring to.

The second code suggests that the Thermostat is not working correctly.

What temperature is the engine reaching?

The car is c350e. I got it diagnosed by an indie, and he recommend to get it fixed / repair at Merc dealer. The thermostat reaches 80 after few minutes of driving. The indie says that he can fix the issue with the thermostat, however he isn't sure if that would resolve the issue with P06DA000 fault.

An Indie who suggests you go to Mercedes!

Get another Indie.

A quick question. I've cleared the error codes myself. I've booked an appointment with an indie to check EML warnings. Will he be able to fetch the errors? I have plugged in my scanner, but I can't see the errors. Indie says that the error codes are stored in the system. Is that true?

If the error codes haven`t re-occurred then why bother with the indy investigation ?

If they have re-occurred then just leave them "live" for further investigation.

Yes, make sense. Thanks

For the majority of faults, if you rectify the error the fault will heal itself. That could be after a key cycle or after multiple drive cycles. That will depend on how Merc have calibrated it.
In this scenario you will still be able to see the original fault with a diag tool long after it has healed.

If however you clear fault codes with a diag tool they are gone. The fault code will only be visible to a diag tool if the error state reoccurs.

Thanks all, I shall rebook the appointment with indie when the fault re-occurs.

My A-class 200 is showing the exact same 2 error codes

1) P06DA00 (stored) The actuation of the valve of the oil pump in the combustion engine has an electrical fault or open circuit. There is an open circuit.

2) P012800 (Stored) The coolant temperature is below the coolant thermostat specified temperature.

Can you give us an update on whether / how you fixed yours?

If your car is equipped with the M270 engine, then the thermostat failure is a known issue. Otherwise, I'm afraid I don't know.

Re the first code. A quick Google ties in with what you said and it may be related to a dodgy wire in the main harness. I guess this is why the indy said go to main dealer.

found this, may help you to be more informed and possibly another indy start with the cheapest way forward

The P06DA00 fault code in a Mercedes indicates a problem with the oil pump solenoid control circuit. This could be due to a high resistance or open in the circuit to the Y130 oil pump control valve. Symptoms include: Illuminated engine light, Insufficient oil pressure, Engine wear, and Potential damage.



Depending on the model year of the vehicle, the P06DA00 fault code may or may not activate the check engine light:

• Model year 2018 and earlier: The fault code can be disregarded if the check engine light doesn't activate.
• Model year 2019 and later: The fault code will activate the check engine light.
  
  

To fix the issue, you can try updating the software of the ME control unit. If the code no longer activates the check engine light after two drive cycles, no further repairs are needed.

It’s a 2017 A class 200, so, yes I believe it mounts an M270 engine. By known issue do you mean the CEL can be disregarded ? Or that it’s a known issue that needs to be fixed ?

The M270/M274 engines have the thermostat located on the underside of the engine making access to it labour-intensive (including complete draining and then refilling of the coolant), and additionally the thermostat itself has a built-in electrical heater plus electronic components, making the part more expensive that your typical thermostat. On the W204 with the longitudinal application of the engine, it's around £700+ from a dealer parts-and-labour, or about half that at an indie. I can't imagine that access is any easier on the transversely-mounted engine on the A Class, and so I'd expect similar costs.

That been said, the fault code needs to be properly diagnosed before condemning the thermostat.
