MK5 Golf Plus TDi 'Emissions - Garage'

[Crasher]

4 dead glow plugs will not stop a BKD from starting.

So, managed to get a VAG-COM with VCDS - Lite, and the fault code came back as;

013112 - Control circuit for glow plug controller 1: Electrical malfunction P3338 - 000

Presuming the 'controller' is the relay, (and presuming this is situated under the engine compartment fuse box) have changed the relay but it still doesn't start and still comes up as "EMISSIONS GARAGE" on the dash.


One thing, is that none of the shops in the area could find the same Bosch part number; 0 281 003 038. They all had 0 281 003 083, which is what was purchased.

When searching online, the 0 281 003 083 came up as being good for the 2006 Golf Plus 2.0 TDi


Is this simply the incorrect relay?

Could there be another fuse?

That is very interesting - Thanks.

The only fault code is the "013112 - Control circuit for glow plug controller 1: Electrical malfunction P3338 - 000"

If this Czech shop is correct, then the relay is compatible;

VW AUDI - 038 907 281 D


Assuming that is correct, then it only really leaves the wiring between the relay and the cylinder head connector

038 907 281 D is for a BMM and BLS engine, the BKD uses either 03G 907 282 or 03G 987 282 A depending on the build date, if it is a 2006 model year it is the A which changed to a B. As far as I can see 0 281 003 038 is not a good Bosch number and if the Tec Doc cross reference is to be believed then Bosch did not do the 03G.

Hi again Crasher.

The Bosch number on the old relay is definitely 0 281 003 038. The VW number is; VAG 038 907 281 D

Considering that it is a BKD engine from early 2006, does it HAVE to be the 03G 907 282 relay? There are lots of people selling the Bosch 0 281 003 038 as THE relay for the Golf Plus. And it had been working fine since the owner bought the car 9 years ago.

One thing however, which I am wondering about, is that if the BKD starts with all four glow plugs dead, and if the car is pumping fuel, the fuel line is self-bleeding, the vacuum lines are working (or at least the headlights raise up and down)... is there any other 'common' fault on these that maight have been overlooked?

I mean, even though tomorrow the entire GP circuit will be inspected, tested and cleaned, you said that this circuit will not stop the car going?


Perhaps there is still a fuse missing for the injectors?

Our BKD Touran had faults on 3 of 4 glow plugs, so I replaced them and really couldn't tell much of a difference. I don't think they'll be the heart of your problem.

Have you looked through the old threads in the forum? Loose wires, crank sensors, injectors, etc have all been to blame in the end for no-start cranking challenges.

I did have a look for "EMISSIONS GARAGE" threads but couldn't find a lot on here.
The plugs tested fine however there was no voltage getting to them which, after confirming the fuse was good, was why I suspected the relay. Then the VCDS also identified the relay (or glow plug controller) as having an electrical fault... With no other codes.

Following on, I would have expected a fault code to appear if the injectors or one of the sensors was failing...

Which is why tomorrow the plan is to have a close look at the wiring, connections and fuel system.

It is an effin ball-ache that no wiring diagram nor fuse layout could be found. Don't forget this car had fuses missing when this job started.

I'm not sure you described how it had gone from running fine for 9 years to having fuses missing and not running OK, if I read correctly. Or did it run OK without the fuses ?

The fuse list you cribbed from a YT video in another thread looks like it was missing a few that may do useful things in the SB set:

5: J743 Mechatronic / DSG (15A)
11: Aux heater control (20A)
15: Fuel pump relay (5A)
27: Glow plug current (50A)

The parts system ETKA clearly states that you have the wrong glow plug controller, I can cross check this with your REG number if you private message it to me.
