T5 2011 flashing coil light help please 🙏

[kee]

Hi everyone new here , hoping for alittle help and advice.

So it all began with the flashing coil light and the maintenance light with loss of power.

Diagnostic said new actuator. Had that changed. Drove home all ok. Next day , the coil light came bk on and lost power again.

I then decided to take to another garage.
Another Diagnostic turbo and EGR fault.
Had the turbo reconditioned who also tested the new actuator which was fine and new connectors pipes. Filters and oil. Lights went off happy days

Day after came to Turn her on... SHOCK HORROR the flashing light came bk on..
Limp mode again.. turned the engine off and started her back up and the flashing coil stays off all day after multiple engine turns and the power is back fully. Until the following morning. This has happened the last 3 days.

So it's there in the am. Turn her off .restart and all is ok for the rest of the day .

Took her back to the garage and he hooked her bk up and it now shows an error with the manifold pressure sensor.

Anyone any ideas or thoughts please .

Thanks
Keeley

now shows an error with the manifold pressure sensor.

So CAAA engine. What's the exact fault code?

 

[kee]

Unfortunately when he plugged it In again he didn't give me the code sorry. He just said it was showing the manifold sensor pressure error

 

[mmi]

Then just let him replace with a new one?

 

[kee]

Hope it is this. Seems a mystery. Keeo getting parts replaced and left with sane issue x

Did the EGR get replaced?
My money is on problems with that.
The EGR needed replaced on my T5.1 which gives the problems you described and after it died for the 3rd time I had it mapped out of the ecu and the vans never ran better since. That was a few years back.

Fab thanks for this I'll have a look into this there's a place close to me that does it I'll give them a call tomo. But yes he did fit a new EGR X

Tell me about it but we keep going

Hi everyone would appreciate any help or advice.

So vehicle has had a new actuator, new egr valve , new manifold air pressure sensor. And the turbo reconditioned.

Below are the code.

Yesterday I had a n75 fitted and this hasn't sorted the issue.

What next garages are telling ne it needs this and that i do as they say and I'm still left in the same situation

Reading on the forum - and I hope this is your problem - can you check the battery voltage?
Sometimes a flat battery can give dodgy codes/faults but I don't think they are the serious ones you are getting. Worth a try - I'm crossing fingers and toes that you have a flat battery!

I've got the battery om charge as we speak. Anything at this point is worth a try so ty

 

[manfrotto]

Are you sure the EGR valve was replaced, not just the actuator?

 

[kee]

Yeah 1000% had a new Egr valve.

 

[kee]

Need battery hasn't worked worth a try.. the garage is now saying it needs a new turbo even though this one has been reconditioned and tested x

 

[whodat]

Sorry to hear that. Keep us updated. I'm sure others on here will guide you.

 

[kee]

Does anyone know if a turbo and actuator need to be recalibrate once on the vehicle

 

[mmi]

So vehicle has had a new actuator,

recalibrate once on the vehicle

No, assuming the actuator was correctly adjusted at the repair shop.

I'm in a mess with it all and I feel like garages are just taking the mushy pea out of me cause I don't have a clue. Feel like I should of gone to vw from the offset . I'm 3000 deep and no better off anyone locally to oldham and know a decent garage to take where ill be able to see all the correct reading ti justify why the want to change parts. 4 parts changed and nothing has cured her I drive to Spain soon in her
