3.0TDI Hot Start Issue, Very Slow Cranking

[snapdragon]

Yes, it didn't seem loose but obviously something is wrong with it, maybe dissimilar metals with electricity going through has caused contact corrosion (poor choice of plating on connector?).

Now my diagnostic socket no longer works (cannot connect to any module) Unfortunately the wires to it were peeping out and got singed and were stuck together so will need to sort that out today.

To crimp it harder I would need one of these babies...

Hi my D3 is now very slow on a hot start up. Not the battery as that is only 12 months old Varta.
Just trying to find out if the fix you did on the connector next to the pedals, sorted the problem out.

Yes, never again have I had the hot start problem.
Last month I replaced the battery after 6.5 years - it was getting weak this winter. Wow the new Yuasa AGM is much better that the old LION AGM (eurocarparts own brand) ever was. I suspect 5+ years of undercharging took it's toll on the old battery.

This issue also affects the Q7 but the connector is under the plenum cover but is the same design and causes the same issue.

Keep your fire extinguisher handy (CO2 not powder)
