Joining the queue of Passat owners with injector problems (TDI wagon carked it)

[OilBurna]

used BP for a while as I got a 25% discount, since my discount stopped I have used Shell. Never used an independent. Depending on the state it all comes from one or two places. BP source from Mobil in Melbourne, Sydney is Shell.

What is the engine code that the injector electronics is most likely to fail??

VW50.

VW died too!

not been on the forum in a while...

a couple weeks back my Passat died at the lights. I thought it has stalled... thinks to my self "that's never happened before". I restart and I CHUG thru the lights only to stall again about 50m past the intersection.

The "glow plug" dash light was flashing and the car would turn over but not start.

Called road assist and car was towed to Berwin. They diagnose injector failure. As the car is in warranty they replaced all 4. It cost me a couple days car rental as they did not have a loaner available.

Warranty up Feb 2011 and I have 63K on the clock so far.

I'll be taking the extended warranty if I keep the car... thinking of getting an XC70.

Usually on BMR 125kw TDI motors. Normally found in Passats and Golf V GTs.

Just had a look at my owners manual. Looks like the Engine Code is CBB.
I this is not a troubled engine also...

[Umai Naa!!]

The CBBB is related to the CBAB, which is known for intake flap and exhaust pressure sensor issues.

Given that yours appears to be an MY10.5 build, I don't think you'll have any issues, as the parts used to rectify the problems I mentioned have been since revised.

Good to know, I only got the car 2mths ago...
Will have to look into the intake flap / exhaust pressure sensor issues though!

Hi
Does anyone know if there is a difference between new(upgraded) injectors and wiring loom and old injectors/wiring? The reason I ask is my car {passat 125 tdi 2007 my2008}has done 113000 km and i bought it with 83000Km and i had a lot of problems with it but i have no idea what work was done for previous owner so it would be good if i can visually identify it .
cheers

My advice would be to contact VW Customer Assist, and find out what warranty work has been done. The service book will tell you where it has been serviced, which, if you choose, you can contact, to see what else was done.

As for injectors and the wiring harness that fires them, it's inside the cam cover out of sight. The injectors aren't an upgraded part, they're an exchange refurbished part through VW.

Mate what is the BMR? The GT TDI Golf has the BMN...???

Perhaps that's the BMN with the Pasabalance shaft etc??

As far as I know, they're pretty much the same engine at heart. The only likely differences being software in the ECU, and some other miscillaneous things.

Thanks for the info,
Contacting VW to get the info should work in theory but unfortunately dealers dont always supply correct info to VW, for example when they overfilled the engine on my car with oil and it started leaking in few places they never mentioned in a report that it was caused by overfill ,instead they made up some crap so that it gets covered by VW warranty and dealer actually told me that it was their fault.

It's your call at the end of the day.

125 GT GOLF (engine code ???) AND PASSAT 125 KW (engine code CBB) THEY DONT USE SAME ENGINES AT ALL ,maybe same turbos and
of course 125 kw is the same nothing else...passat is comon rail and I think golf GT is not...corect me if Im wrong.

My 2007 103kw also few times had fault code injector.1or2.. for now I just delete them and it still goes only 33oookms on clock.. but there is a bit more smoke under heavy throtle...
cheers

Fraid not Oli, in my comprehensive erwin technical manuals produced by VW, the BMN engine in the GT TDI is identical to the 125kw TDI in the Passat except for a balancer shart in the PD series prior to MK6. I can't comment when the Passat actually wnet common rail, but for the GT's it was in the MK6 GTD. Now that they are both common rail, the rules have changed, but from my investigations it would appear any of the 125kw TDI PD engines may have suspect injectors. I've asked around and there have been GT TDI's fail too, so I'm thinking ahead for the worst and investigating aftermarket injectors, just in case! Be good to know at what month VW decided to switch to the improved injectors in the MK5's ( if at all! )
