Spluttering - UPDATE 04/07

[Alex]

Think it's on a Beru one at the moment, think I'm gonna change the dizzy first though because it's more of an unknown. For all I know it may still be the factory one, don't know if it's ever been changed. Coil I know is five years old.

Got no idea what a G40 dizzy is worth without calling a parts department - let me know what you want for it. I'll pay decent prices for it, I'm not out to drive a hard bargain. Just want the bloody car working again.

[Alex]

And there's more.

Bought a dizzy from Pete Mirfin (tried and tested, and fine) which arrived on Friday. Just finished fitting it.

The car wouldn't start at all this morning, again. Turned over but wouldn't fire up. Changed the dizzy and it spring back into life straight away.

It's running smoother and will now cruise at speed, but I can't go more than about half throttle without it bogging down and juddering like it was before.

Which I guess leaves the coil pack?

I'm going to change that tomorrow, tipping the spendometer at just over £150. If that doesn't work I'm not sure what to do.

Starting to wonder if the coil and dizzy were both faulty. It's definitely healthier on the new one.

[Alex]

So yeah, no longer an intermittent missfire under load. It's now a constant missfire under load. Every time.

Which is great timing. Caroline's car failed its MOT last week and we've SORNed it, so she's using the Passat to get to work. Which leaves me with the Polo and whatever cars we've got in at work. Our RS Clio long termer went back to Renault three weeks ago, our Kia Soul has a flat tyre (new wheels and tyres arriving this week) and our Toyota Yaris is a track car (which currently has no expansion tank, so that's not suitable for the commute to work either).

So unbelievably, despite having an abundance of cars none of the fuckers work!

Did you set the ignition timing properly with the new dizzy?

Constant missfire under load does sound a lot like the coil breaking down (or possibly leads/plugs), but as you've changed the dizzy I'd make sure you've setup that properly too.

[Alex]

I didn't do it, Nick did. But by properly, how do you mean?

Coil pack is the only constant in all of this, fingers are all starting to point in that direction.

[Andy]

Am sure Nick'll have done it right! Just read like you'd just bolted the dizzy on without doing the timing.

[Alex]

Yeah we based it on the old one then fine tuned it. Trust Nick to do it right more than most garages but didn't know if there was anything weird we needed to so beforehand.

[Alex]

GSF have three coil packs in stock.

Unbranded at £26
Beru at £36
Genuine at £45

All three are in stock, so I can collect on my lunch break. Win.

Thinking probably going to go for Beru - it's good quality stuff from experience so far.

Or do you reckon it's worth going for genuine stuff?

Opinions?

[cheys03]

I went for the unbranded iirc. I compared a BOSCH and the unbranded side by side and they looked identical, even down to the casting and molding marks.
It's been good for over a year so far. Up to you for the sake of £10 it may be worth getting the BERU. At the time I bought mine I think the only choices available were unbranded and BOSCH and the BOSCH was more expensive than the 'genuine' one is now.

genuine may be beru! but in a different box!

although valeo was oem IIRC

[tdh-syorks]

Just reading up on your thread and we were currently having the same problem as you are with an cossie which me and my mate just bought, we tracked it down to ignition fault, but after changing the dizzy and coilpack, leads etc (which did improve it a lot) it was still the same spluttering under load, we ended up throwing towel in and took it to a rolling road for tuning. They instantly said the fuel pump was knakd.
This is where we are at the moment so ill post tomorrow when I've fitted the new one to let u know if there's any improvement.

Cheers Tom

[Alex]

So sick of the arseache I ended up buying genuine - came in a V-Dub box and everything.

Fitted it in the car park at work and I'm happy to say that (so far, at least) it's absolutely fine. Took it out for a spin and it's

Which makes me a happy boy!

Will update you once it's had a few days of normal use though, just so this topic can be used as a reference point.

[Varley]

High Five!

Glad you got it sorted (touch wood!)

[Alex]

£180 lighter for the privilege though, which isn't ideal. Thank god for credit cards...

[hayesey]

what did you buy, an ignition coil?
