Hi ,

While running a VCDS test a came across to some codes for which I cannot find a description yet,so I am appealing to you guys to help out.

Many thanks,

Gabi

First of all, I suggest you edit out the VIN number from your post.

I can see 4 faults but all of them show the description.

005269 - Switch-Over Valve for EGR Cooler (N345): Open or Short to Ground

Faulty solenoid or bad wiring

005658 - Glowplug for Cylinder 1 (Q10): Open Circuit

Likely to be glowplug connector unplugged, faulty glowplug, faulty harness

005734 - PD Unit Injector; Cylinder 1 (N240): Electrical Malfunction

Bad injector or wiring.

000564 - Boost Pressure Regulation: Limit Exceeded (Overboost Condition)

Hi there,

Update on the above issues.

I have replaced the electric wire loom connected to the injectors,replaced(G13)boost pressure control sensor,valve unit to EGR ( where apparently the n75 boost pressure control valve is located for models after 2007) and had just run another diagnosis test with an OBI II tool,cleared all the above faults,restarted,with engine management light off , but not for too long as just after 5 min it reappeared again. Run another test and got the error code ( Switch over valve for EGR cooler Open or short to ground. Code N345).

I have just ordered the EGR cooler and will now more about the outcome next week,once is fitted.

Hi guys ,

An update on the EGR issue, described above. I have just had the EGR cooler replaced with a new one,and also had a scan with a OBII diagnosis tool. Initially it cleared all faults,but a few minutes after the Engine Management Light came on again. This time,I have also had a faulty light bulb signal appearing on screen. Cleared all faults and run another test,with the same results:

005269-Switch over valve for EGR cooler ....Open or short to ground.....N345..........P1495

Can anyone please help?

Which did you order?

1. EGR cooler

2. the valve for the EGR cooler

The N345 is the valve for the EGR cooler NOT the EGR cooler itself.

Well,I have told to the local parts department to supply me with the valve for the EGR cooler,but they told me that the only valve will be the one attached to the EGR cooler itself,and which,unfortunately does not come sold separately but as a whole unit with the cooler itself attached.

Do you have any pics or links where I could see the location of this valve,if there is another one?

Many thanks

If you give me your engine code I will double check the part numbers. It will be on the options label which can be found in the service log book or under the carpet in the boot.

Sure... It's an Octavia 2007, 1.9 PD TDi,engine code BXE.

On this car the N345 is an integral part of the solenoid valve block which also contains the N18 and N75 valves. It has an electrical connector and a bunch of vacuum tubes connected to it. The solenoid valve block has a distinctive shape.

It looks like this http://www.ebay.co.uk/itm/VW-AUDI-SEAT-TDI-Solenoid-Valve-Block-6Q0-906-625-/320746291111?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4aadf7ffa7

There are two variants...

6Q0 906 625 E

6Q0 906 625

Which one is fitted depends on your VIN number. You can get the part number off the existing solenoid valve block.

I have just replaced that unit which contains also valves N18 & N75 about a week ago and yesterday I had the EGr cooler itself fitted ,all new original parts from TPS- VAG Group. Now,could it be possible that an OBDII scan tool won't be able to effectively clear all previously logged faults or that the unit itself had a fault? Any ideas what to do next,as I have prety much exhausted the options I could have thought off!

Any idea on how to check if this unit is faulty?

Many thanks for your help

Have you checked the wiring to solenoid valve block?

The wire that controls the N345 runs from the solenoid valve block to the ECU.

Here are the wiring details...

The signal side of the N345 is on pin 2 of the 6-way connector on the solenoid valve block. It is a green/black cable that runs to pin 15 on the 60-way ECU connector. IIRC, the wire passes through the same 14-pin connector as the coolant temp sensor and glowplug wires.

The supply side of the N345 is on pin 1 of the 6-way connector on the solenoid valve block. It is one of three black/red cables that join and run to pin 21 on the 40-way E Box connector.

Nope....but I will get it done now!

Many thanks for your idea,Briskodian!

Please update the thread so others are aware of the fix
