Likely Haldex pump failure on golf r

  • Likely Haldex pump failure on golf r

    So I bought a reasonably low km mk7 golf r just yesterday in what seemed good condition... Boy did I underestimate the fault that the inspector found which just said intermittent accelerometer error in the haltex 4wd... Just thought it was a sensor error that wasn't current and he didn't seem worried about it either.

    Feeling silly now as I should have driven it hard off the mark when I test drive it because on the drive home I accelerated hard on a slightly damp road and found traction control kicked in.

    My newly owned obdeleven shows it as a haltek pump fault. Reset the fault and it comes back.

    So from reading I believe the chances are a clogged filter which has now led to a failed pump.

    So do I order a new pump and oil. Then jack it up and do it all in one go... Or do I change the oil plus clean the filter in hope it fixes it. Which means getting under the car twice. And also possibly needing to buy oil again..

    Anyone got suggestions on where to buy a haldex pump? Seen some from UK on ebay. Seems local online suppliers I saw are out of stock.

    Had many of these issues in our workshop on the Golf 7 R.

    Replace the pump, fill new oil. Make sure you do the pump learn function (basic setting) with VCDS afterwards. This is a very important step otherwise the new pump wont actuate the haldex clutch.

    We had some luck getting the old pumps to work again but we had to strip them, clean them. Reassemble.

      Sounds like I'll just buy a new one then assuming they are just shy of $280 plus oil from what I've seen. Rather than pull mine apart and make it a weekend job, rather than just an hour or two I guess if it's just a replacement (plus clean filter and housing).

      Do you have a good source to buy them from and/or if Sydney based maybe I'll pay to get it done. Won't go near vw for this as I'm sure thatll cost a pretty penny.

            I sent them a message already. They were the local supplier online that seemed good price... But out of stock. Hopefully new stock is in soon and it's not one of those that could be months away from restocking

                  I must admit it is a weird business name, but i have purchased form them several times now and they are good to deal with.

                  Wife did question the delivery left on our doorstep from VAGParts though....haha.

                    See here showing the buildup on the filter after only 37,000km's: https://www.vwwatercooled.com/forums...ml#post1310591

                    You might be lucky to get away with cleaning the filter and replacing the oil.

                      Friend had one go at 31,000km in his S3.

                      All to common of an issue it seems.

                        ....crazy. Sounds like it needs checking and cleaning every 12-18 months then.

                          Seems to be quite variable how quickly the "black frog spawn" builds up.

                          Mine needed cleaning at 2 years/15,000Km, and I'm going to have it cleaned at 3 years to see how bad it is then, and therefore whether it needs to be cleaned every year.

                          There are a few theories around as to the possible cause. One I can debunk is different haldex fluids are better than others, as it is all the same fluid, regardless of which bottle it comes in (made by one factory in scandinavia is what I read).

                            I've ordered some haldex oil in so lets hope cleaning filter and oil may fix it... but I realise this isn't likely to solve my problem as the pump has likely died now..

                            But I will use the oil again if/when I replace the pump. Hopefully I can get a pump earlier next week but haven't heard from vagparts yet....
