Running problems on ABY, surging-cutting off

[newsh]

I'm pretty sure I got mine from Europarts, and it fitted fine, ISTR there were 2 types though, maybe the one that works is the VW Transporter one?

^I'm pretty sure the one they gave is not the same sa the one in the car, just a matter of a different plug. If not maybe a DIY plug change should do the job. Do you have anymore info on what type of transporter it was? Engine size etc. Cheers

If you are talking about the auxiliary water pump (aka the afterrun pump) - two pipe connections and a 2-pin connector for the S2 application then you need to specify it as 034-965-531-C. Roughly 90 quid plus VAT at a dealer but I dare say VAGparts.com can beat that easily. I see it at £69 now but should be cheaper with forum discount -

^Thanks mate, i think the one on my car has a 3 pin connection. I got another pump from a scrappies off some other VW/Audi, looked pretty much the same. Only thing is it has a two pin connection. Or i've got it a tad mixed up and the car has 2 pin and the pump has 3 pin. Either way would it be advised to take up the soldering iron and frankenstein this b-itch?

Cant edit the above post.. just to clear things up, i dont know what was going through my mind when i wrote the previous reply... i should have wrote the new pump has 3 WIRES and the original has 2 WIRES, the pins are still two on both versions..

After looking for some un answered question on the S2, we found something! Previously a mechanic at a garage took off the intercooler, and he just left one side hanging, there was nothing to keep the pipes secure.

After sorting this out, the car wont even start up now. Checked the plugs, coil, and changed the MAF. Still nothing, it started up fine befire, with funny idle and spluttering, but since yesterday for no apparent reason it just wont fire up. Its turning, it wants to start but nothing. Fuel pump seems to be working, everything looks in order, nothing that should prevent it from firing up. The clifford alarm system is on our list to remove today. Its one of the older systems Clifford 300 and something or other.

Well ****me! There is life in frankenstein! It's running pretty nicely now, can just sense a slight miss, but it fires up, idles normal, sounds as it should, all good...As mentioned before we went through the process of eliminatingw what could be the cause of the car not even starting up now, all the ingredients were there, but couldnt figure out why it just wasn't coming together. We were all ready to strip the alarm, assuming it was somehow preventing it from starting, but as they say assumption is the mother of all ****ups.

Before we done that, by chance we took out the spark plugs, we've checked for sparks earlier, and it was fine, but never actually took the plugs out. Took them out, they were drained, gave them a good clean up, heated the ends and stuffed them back in. VOILA! It done the trick, well happy that's sorted. Just need to get a few vacuum pipes, and the rest of servicing bits and bobs

Thanks for all the ideas, top people!
