Turbo Charger Issues P1496,P1497 and P2562,P2563

pipe is clean unfortunately!!!!

Has anyone found the issue..??

I’ve been battling this for 6 months now, today I’ve literally honed in it. I bought Lexia last week so since having this I have been able to logically zone in on what seems to be my issue.

Exactly as those screen shots show, where the actual turbo actuator position and expected position are way off. I have been through the whole vacuum system, replaced all pipes and components. Found some decent leaks on the brakes, egr was knackered and replaced. So now I’m fairly confident that it’s a control issue, I.e wiring.

this thread is the closest I’ve seen to someone with my issue and recent, please update if you’ve managed to sort

In case anyone in the future struggles too, and in their searches come across this I’ll tell you what I’ve tried so far

Replaced maf and map sensor, a fresh turbo assembly, tested and replaced all vacuum pipes

Brakes showed the biggest leak, but nothing would do much apart from smoke it’s head off and run like crap give me never ending p11aa, p2546, p1496 and endleeeeeeeeeeess p3007

Finally bought a lexia, started seeing trends in data, then put a vacuum gauge T,d into the actuator pipe on the dashboard so I could actually see what it was doing.

The gauge was magic!!! Realised the vacuum pump was struggling and sure enough the brake pedal feel is amazing and the turbo actuator is fixed but…………still clouds of smoke and running really poorly!!

I also changed the egr valve after testing it it wouldn’t energise, but the new one would’nt and still won’t initialise!

I’m at the stage tonight where I’m hoping like hell I’ve actually fixed the original problem but in the process manufactured this one.

So the fault Code I’m having is egr related can’t remember the code, but in trying to program the egr I’ve woken something up egr related because it’s never mentioned it in all my troubles before, making me think it was turned off.
But my idea at the moment is the p3007 is for inlet pressure higher than expected, after watching the pressures while driving etc yes they are out, is it now because the air mixer and egr aren’t opening and closing to help regulate the inlet pressure?

We deleted the egr out of the map and blanked it right back in June when this black smoke issue raised its head, we’re guessing that because it’s deleted in the program that’s why it won’t initialise.
The blank has been in and out a few times and made no difference to the smoke.

Otherwise it’s got to the stage I think where it’s wiring or ecu

I did start checking the pin data on the egr plug, but I got as far as pins 1 and 2 and found it wouldn’t energise, I did’nt do the other 3 wires I think there is. So still hope if the map idea doesn’t work

It’s been a very interesting and frustrating time

The EGR reduces the NOx emissions and although not a perfect system it's what we have. So bear in mind we don't support any blanking or crippling of emissions systems on this Forum, as it's illegal for public road using vehicles, so can't help you with faults that are likely caused because of this. We state this in the AUP that you agreed to when joining

But yes, expect problems with the engine management system if such actions have been taken. Our advice is to have everything as it should be and then address any remaining faults.

Yup understood.

This has been my point to my mechanic, hence buying brand new egr valve and fitting it. And reinstating it in the file.

Which has all been done and guess what it runs even worse

But once again in this hunt I can say…….I think I may have found it!!!

I have a fault will not clear! F303 on the bsi

A communication error

When the egr was fitted he said it wouldn’t intilialise! I also get an egr fault

And says first initialise failure

Checked all pin data today, I’m getting 5v instead of 12 to the egr

Trace that back and back, and the ECU is finished!!!

Lots of low or incorrect readings between pins as I worked my way through

So a 2nd hand one is on its way

I’ll believe it’s fixed when I bloody see it

Finger crossed - it's logical that if there is a comms issue that it won't reinitialise an that will be causing problems. Be aware the engine ECU and BSI need to be a matched pair along with the immobiliser in the fobs. If changing the BSI make sure you printout all the configuration pages as you'll have to configure it specifically to match your vehicle characteristics and specs.
