Central Locking Pump Repair Kits Feedback
Just replaced my central locking pump and thought I would share my experiences with the forum to help anyone else with this problem.
After whipping out the old pump and taking it to bits found the usual problem, shattered graphite impeller disc (smaller middle disc with four grooves in a cross shape).
What to do ? Buy replacement graphite discs or re-furb pump ? Both options to be got off eBay for best value IMHO.
I was at first tempted to go for replacing the graphite discs but after taking the pump to bits found that to reverse engineer the process was not that straightforward, how the hell do they go back together ? With no immediate information to hand I got some feedback from this forum (thanks again "old_skool" !!) but still wasn't confident about putting the dics back together correctly.
After looking around on eBay I found a guy who sells what he describes as a kit to repair the pump for £40. This may seem more expensive than replacing the discs but the guy gave free postage which was useful......
Due to earache from my missus who kept setting the alarm off due to the knackered pump I had to make the decision to buy the pump repair kit for what I thought was going to be the quickest ball-ache free fix for me. paid my money and two days later pump repair kit arrives.
Opening the parcel the first thing I noticed was that the motor unit is substantially meatier than the old Audi OEM motor. The discs are also thicker than my old unit. I am not sure what the motor has come off but I have read elsewhere that VW Passat motors are better than the Audi unit so it could be off a VW (or even a Merc ?).
Took me five minutes to fit the pump to the car and hey presto, working central locking. Happy Missus, happy kids and all is once again right in Audi land !!!! The best part about the kit was that I did not need to re-code anything. Simples !
In conclusion. If you take the pump out of the car completely before fitting replacement bear in mind that you will have no immobiliser working (potential insurance company get out clause) and no electric windows. To go for the option I did or get the disc replacements is neither here nor there. I cannot comment on the thickness or provenance of the disc kits and as mentioned above I wasn't happy about how to fit them into the motor correctly.

Hope this was useful feedback for anyone else with this problem.
