Passat Diesel - Cut out
« on: 07 October 2023, 21:33:11 »

I have a 2009 Passat Estate, purchased as a daily hack now the Rangie has gone to heaven. It's a 2.0 TDi, 6 speed manual. Very high miles - 209k. I bought it with 206k on the clock, and have done nothing other than a cambelt kit and water pump (DIY) about 2000 miles ago. It has always started and always driven exceptionally well.

Day before yesterday I left home, drove less than a mile, and it just suddenly lost power and died. Like fuel starvation. I managed to roll into a layby, tried to restart, no go. It was trying (and tried harder when cranking at WOT) but wouldn't go. I didn't try for long, because I needed to get somewhere, so I walked home to get the other car.

Today I went back to the VW. Plugged in a code reader - no codes. Cranked it a bit, and after a short while it caught, coughed a bit, and then ran fine.  I went for a spin, covered 10 miles without any issue at all, plenty of power.

The fuel tank was full, almost to the brim, when it broke down. It was filled up the night before and had only covered 15 miles home. BUT, when I last refuelled the night before, it was literally on fumes. Range saying 0, gauge not moving (I know, I know!)

I am wondering if I ran it so low, that it took in some air or crap or similar, but odd that it took 15 miles after refueling to show up?

Guess all I can do is keep an eye and see if it reoccurs  :-\

Does it have a lift pump?

Also, might be worth changing the fuel filter, although it's a finickety process to bleed.

I believe it does.

I changed the filter when I did the cambelt kit 2000 or so miles ago - I filled the housing with diesel, and it fired straight up with hardly a cough! :y

Started on the button this morning, I'll take her for a (local!) drive today and see what happens. I think it's going to be a case of just see if there's a repeat, and hope it was due to the previous low fuel!

I ran the R Class out once and it wasn't happy for a while after... fortunately it didn't kill the lift pump :-[

If it fired straight off then it sounds like you've gotten away with it.

I know that, because I speak English, not an American bastardisation of it.

Sorry, Al, you just can't be a Yank, no matter how hard you wish  ::)

I'm off to read OOF terms and conditions ,

seems the "grammar  police" and "English spelling division" are  scrutinising OOF  :o

I'm constantly making grammatical and spelling errors  when posting  :-[

I need to check how many points I've totted up ,I might well loose my "OOF posting licence"    :P

all joking aside ,,,

I hope James hasn't had further issues  :)

Car was fine yesterday. It's got a bit of a squeak only at idle / very low revs. Hoping it's the aux belt bedding in, and not the HP pump!

I'll take the flack for running the tank "moist"  ;) Let's face it, it wouldn't be a first and probably not the last time I've done it. It's usually the Omega estates which catch me out though - normally more careful with a diesel for obvious reasons....

Might be air, the VW common rails are a bit shitty for this as they do not self prime and if actually ran out need a bit of work to get them running (usually cranking and popping the return pipe off the filter). The filter housings are easy to crack when changing the filters also.

That said, it could also be a crank sensor showing no output, you will just have to run it and see what happens

cheers Mark :y - 100 miles or more now and not missed a beat... I'm keeping everything crossed it was just air from when I ran it so low....
