Hello All,

Recently Changed the EGR.

I was getting the "CHECK INJECTION" warning for a bit. I removed the EGR and cleaned it a while back with some success.

The Issue has now returned after a few thousand miles and after 2 weekends of cleaning it to identify the issue I had to give in and get a new one. This has made a noticeable improvement! However, when I am now on the motorway doing 70mph to 80mph the Warning re-appears!

This was the problem before but it just happened at around 50mph. basically you’re driving along and you hear/feel a very slight thud and the warning appears a split second after this happens. If you then attempt to accelerate the engine flat-spots and you cant get any more out of it so you are reduced to using the torque down low and just building up momentum.

If it was a petrol car it feels exactly like the fuel mixture is too rich and/or the PCV system is blocked. I took it to my local garage for it to be plugged in. Guess what... No Fault codes stored. Also if you pull-over, turn off the engine and wait till the car shuts down and the immobilizer light starts flashing and the re-start the warning clears and off you go with no issue... I’m confused!

It was throwing up a mechanical fault beforehand when it went for a standard service and the code was P2263 according to his system which I believe which was pointing to a pressure issue due to a mechanical failure of the EGR and or Turbo.

When you start the Car after a rest overnight or at the end of the working day it throws out a little blue smoke if you rev it, however never any other time after it is warm. A bit when you give it some but I kind of expect that from a diesel. I read somewhere else that some sort of oil drain may be blocked?

Don’t know where to start really as this is my first Diesel and Turbo car and I am learning as I go.

The Engine is a 1.5 DCI 106hp either a K9K 732 or K9K 734 (Not sure what the difference is but I have the one with the perpendicular solenoid EGR Valve, not the straight one).

If someone could Also let me know how to find out what engine model I have that would be handy for further servicing and parts needed.

I have done some research into getting a new turbo and it looks like there is a small housing with a Diaphragm inside it mounted to the turbo. Is this the case? And could this be the issue if it has perished due to the heat?

I am thinking of taking the turbo off and stripping it down and giving it a good clean-out anyway. Does anyone know of a “KIT” which one could order for all the gaskets and seals to re-condition this model of Turbo. Alternatively could someone let me know what I should order if they know of all the parts that I would need to get the job done. Or is it best to just get a new unit.

According to a few websites the part number of the

Turbo for this engine is:
5439 970 0070
or
5439 970 0030

Any Help would be appreciated

Regards and thanks again for the help

Blue smoke is oil burning. So you may have an oil leak somewhere along the way. Have you checked the oil level recently?

Sometimes its something simple rather than extensive
