    Running problems on ABY, surging-cutting off

    The S2 ABY has been standing around for quite a while, well over 6 months..I finally tried bringing it home. Everything was working although the auto check didnt say OK because i reckon it had a water pipe leak or something or other...We fill it up, it was pretty much empty before that.

    Gently set off it was driving ok never tried putting my foot down, just nice and easy, but then i realise the temperature has dropped back to pretty much nothing. I stopped and checked the water even though it hadnt over heated, we out a bit in...

    Got onto the M1 and we pulled up to the service just before sheffield southbound because i had a brake warning light on aswel. Again we checked the water and it was still there..

    So we set off again, but now the speedo packed up, nevertheless we carried on, slowly accelerating up past 50-60 i was just about to try and check the boost factor as it was revvin at around 4-5k so i reckon i may have been in 3rd. Next thing i know there's no power in the car, engine just not willing to rev or speed up. It was like surging and then cuttin off, surging and cutting off, very small surges.

    I pull over to the hard shoulder turned engine off and tried to get it going again, engine idle was up and down not in one place, slight white smoke coming out from under the passenger door although there were no signs of fire. Again it was just mis firiing and surging and cutting off, i got it going gently but as soon as i accelerarated a bit it plays up again as before and throwing out a bit of black smoke in the process.

    2 hour wait for recovery...'err mate this car is four wheel i drive as we said'...'erm i'll just have a look at it and we'll get another truck down here after i've left'
    I must have been on the hard shoulder for about 3 hours and it was freezing!

    Got the car home, and i'm hoping one of you can point me in the right direction. If it helps before the car was stationary it ran very sweet, no faults nothing, pretty healthy engine 113k on the clock and has been at a crusing indicated speed of 1.50 mph with no mods.

    surging and coughing sounds like a split air hose i could say.These things deteriorate if not in operation.As for the smoke,could be from your split hose.However the OK sign does not leave and stays yellow usually when there is a shot bulb in the brakes.

      We've checked the upper two big pipes, i think im right in saying the go from the inter cooler to the engine, and another goes around. And there is another 3rd pipe, which goes from the botom of intercooler to the bottom of turbo? I might have got the sides mixed up, but i've had someone look at it, and he says the top two pipes seem good, no cracks, now it's just the bottom one to check.

      I was wondering if it could be some sort of electrical fault aswel? ECU playing up?

        get vag-com or some kind person with it to connect it up and see what's happening,
        I'd be tempted now that it back home to go round all the jubillee clips/connections, TB hose and the rest of them again , allied with vag-com error output should give you a good start, it sound like a boost/air leak as mentioned by others, everytning is a suspect ; maf, wgfv, dv etc,etc, there's many threads in here relating to the symptoms you describe, shouldn't take long to get to the bottom of though, worst case 2 hours of inspecting/reconnection.

            check the plugs too - if one has a hairline crack in it, it will fail under load.......

              I'm going to enquire if someone local has vag-com, i'll let them have a butchers at it at the garage, and then check the remaining inter cooler pipe. Get a second opinion and wait too see what can be done or whats the cause.

              Before that i think i could do with a power steering pump as it's off the car now.
              Am i looking for ones from any 2.2 20vt engine eg from the RR quattro, ABY and 3b s2, and the early s4 and s6's? Or will any other ones from a coupe/cabrio be the same?

                A bit of info regarding the p/s pump, i'm led to believe that the pump is dependant on engine code i.e 3B, ABY, part no's are in link.

                I've been on the look out for an ABY pump for a while now hence the link, phoned various breaking s2 ad's, they seem to be quite hard to locate.
                New are iro £450 GSF do a p/p for £150 but are crap, check out GT500's recent thread on his ski trip, that was the second one Rob had tried.
                Good luck in finding a s/hand one.

                  Depending on where you are im not too far from Sandy and have Vagcom so can prob check it out for you. Also have a pressure test kit, and soon a compressor to test with which i am borrowing since need to trace a leak on mine too.

                  Drop me a pm if you need a hand, but prob wont have too much time until sat morning

                    I've been ringing around for a pump, and ended up getting it reconditioned for £80 with 12 months guarantee. GSF wanted near £140 iirc. Europarts was about £120. Should be gettin the recon'd pump back today...

                    And thanks Greg, i've got someone coming to look at the car after the pump is fitted and then if we cant figure anything out i'll be sure to drop you a PM, i'm not far from Sandy...in Luton

                    Also i've been told i need a electronic water valve? is that the correct name? It's leaking water at the mo.

                          Wrong again i think what i'm talking about is the auxillary water pump/valve. I've ordered it and its going to cost just under 70 pounds. I hope that'll be the end of the water leak, next step is to get the car going.

                            These guys are seriously taking the biscuit at GSF and Europarts now. I've had to order to auxilliary water pumps now and they both have a modified plug. They dont supply the original plug type, is there any way round this? Does anyone know why it's modified?

                              Don't bother dealing with them as people are having bad problems with parts from them (check out gt500's thread about his psp pump)

                              Use vagparts if you can as its generally either just as cheap/cheaper, right first time and genuine parts.
