Maybe I'm getting a bit muddled actually, i could just be on the petrols.

When you say you turn the ignition on and you just get clicking? Is that trying to crank it over or just with the ignition on?

Your local garage will have a hand primer by the way, we have to use them all the time at work after changing fuel filter because it gets are in the system and konks out. Disconnect one of the fuel filter pipes, (The outlet pipe, it will have an arrow on it), prime the fuel through the filter into the pipe with the hand primer until the primer goes hard, disconnect hand primer and reconnect the fiel pipe to filter, should then start :)

Just with ignition on - so dash lights are on but you don't go to start it.

I think he's going to book it in with a local autospark, which could then be costly.

I've managed to acquire vagcom but we're just waiting on a £7 cable coming through from eBay.

Speaking to the mechanic (on site HGV mechanic) at work, he reckons my brother has just not connected something up whilst he's been doing this work, but my brother says he's retraced all his steps & everything is connected fine.

If he's changed the fuel filter and not bled it then it wont start.

Air mass meter unplugged per chance?

When in doubt, leave it to the proffesionals.

Fuel filter was done some time around May - so plenty of miles have been covered since.

AMM - nope. Just popped the airbox top cover off, changed the filter & re-fitted.

Looks like we're hitting brick wall after brick wall. Guess it's time for the pros to have a look like you say. That could be a big money pit though. Change this item, £100, oh it didn't work, change that item, another £100, oh that didn't work either....

Shouldn't be too pricey, just need to see a decent mechanic ;)

The problem has been rectified .............

clogged EGR valve. Just needs cleaning.

As it's lashing it down here, the guy said to my brother that he can either clean it himself or the bloke can do it. My brother got the bloke to do it as he wasn't about to clean it in this weather, but needs his car.

£95. £41+VAT was the diagnostics.


EDIT: I'd forgotten to tell him to check his EGR valve ages ago. I've been telling him to take a look at his throttle body for a cleaning for some time now but he hasn't.

Will the throttle body need programming with VAGCOM if removing from the car?

His is a 2002 plate 1.9 TDI if that makes a difference.

I have a 1.8 2001 plated (51) Astra & if i remove my throttle body to clean i don't need to program it using OPCOM, i can just re-fit it & away i go.

No need for resetting, just start the engine as normal and drive  :smiley:

That makes things a lot easier then. Cheers.

So what's with the how-to mentioning aligning via VAGCOM then?

Is that not for petrols? Never seen the how-to for diesels  :undecided:

Umm, yeah that could've been it then  :grin:

Is there any difference between doing it on a petrol/diesel engine then, or is it only the aligning that is different?
