Any help with this will be appreciated. I now have a dead 225BHP golf sat 15 miles away :cry:
Summary of problem......
Was in 5th gear about 60mph. Foot down halfway. Turbo spooled. Boost came in and she started to go.
Then there was a slight pop. No power. Put clutch in. Engine then died.
It turns over, won't re-start. Checked boost pipes. No oil in water. No mayo in the cap. No white smoke after the pop.
Anybody had a problem like this? I'm thinking the head gasket may have gone, but have no experience of gasket failure on diesel cars.
Also was wondering if the fuel had somehow given up. But the pump still primes on ignition.
Any helps a winner! Cheers :smiley:
-
is it a pd or non pd? does it turn over faster than it used to?does the glow plug light still come on when you put the ignition on?
try squirting a tiny bit of easystart down it just to see if it can physically run for a few secs.
-
Cheers for the reply Dan.
It is a PD engine. 150 standard running a hybrid turbo and mapped accordingly. Does seem to turn over easier, faster i'm not sure.....
The glow light plug does come on as usual. It has seemed to be running a little bit sluggish recently and not taking off like it used to. I put it down to needing an oil change.
What you thinking?

okie dokie, i was thinking relay 109, but as the glow plugs light is working its not that.
1st check id say, on the egr valve make sure the anti shudder flap hasnt somehow closed itself!
next thing id say is check its getting fuel. id do this by removing the glow plugs one at a time and crank it over. youll see puff of fuel/air mix escaping if its getting through. if not you know theres a fuelling problem. next check the clear fuel line between the diesel filter and the fuel inlet, take it off the fuel rail and put the ignition on with a cloth under it to carch any spillage. if it comes out here but not the bores id say injector loom fault - maybe the tandem pump. give the oil a sniff, if it smells like diesel it could be a sign the tandem pump has taken a dump. these are all free checks!
thing id say is have it scanned as this might throw up a problem straight away and save all the maybe's. i think these engines have a crank sensor, which do pack up and prevent running.
after that id say get a compression test done the check for worn piston rings or anything like that.
hope u sort it theres nothing as irritating as a broken car than u cant fix!!

Cheers for the info Dan. Much appreciated!
-
let me kno how it goes!

Its been looked at by my mechanic this morning as I am struggling for time at the min.
Compression was checked. Theres a sh!tload he says. So thats a winner. No gasket failure.
He is thinking the same lines as you that it could be the tandem pump. It's off for further invest at his garage as it's on a random persons drive at the min! :grin:
Thanks again for the info Dan. How big of a job is a tandem pump change?
-
probably about 45mibs work id say on a go slow. just remember to renew the gaskets or fuel and oil will fly everywhere!
-
Sweet.
I'll get an update here on Wednesday. See what else gets thrown up.
-
Well, it's worst case scenario.
The engine has stripped the teeth off the cambelt. They are goin to investigate and see whats siezed to cause this.
Gutted is an understatement!
They reckon it's top end, not bottom as the starter is still turning the bottom end over.
IF it's smashed the valves it's gonna cost a fortune. But, I could source a gas flowed head for the swap. Fingers crossed it's a best case and it's not head off. :sad:
-
Hmmmm! Mate, that is f**king rubbish!
So the engine siezed!? No oil? You haven't been using sand to help the engine run better have you?
That sounds very expensive...
Keep us posted, good luck!
-
euch that sounds discusting. id say either the tensioner went sticky or the water pump seized up
it may just be dead valves hopefully no damaged pistons! gd luck chap

Cars now fixed. Big thanks to Kings Lynn VW Centre....again!
Seems something timing associated had siezed. Leading to the stripped cambelt.
The lads checked everything was free, cam, water pump, crank etc. It was all free and moving so the car was timed up and started. With a new crank pulley. We were worried about the valves and head damage.
They took it for a run and it is running sweet. So that was a lucky escape!
The crank pulley had sheared a couple of bolts. So maybe it could have been that vibrating against the block, I haven't a clue.. dThe guys said to be honest they have no iea and have never seen that before. She has done 100 miles tonight of mixed driving and is sweet as a nut.
Anyone in the Kings Lynn area I would recommend Paul at this place. Again they have done a great job on my Golf: -
