2 - 3 months ago I fixed my previous Haldex issue as the pump had gone due to being clogged up and had burned itself out on my 2010 A3 Quattro with Gen 4.
Now another error has popped up making the 4wd system intermittently working and throwing up a 2248 Valve for controlling clutch operating angle N373 error.
Bit of digging and most likely going to be that the haldex controller is corroded however ive took it off and sealant looks in good condition except of a couple of very tiny areas that have lifted...maybe enough to allow corrosion in.
Spoke to a very helpful guy on http://www.haldexrepairs.co.uk/ who I have ordered a filter kit and more oil from after being told by Audi their is no such thing as a filter on the system for the Gen 4. It's possibly the filter is blocked causing an issue and at only £52 for a new one and £1050 for a new Gen 4 controller its work a shot!! Lad from the above site actually strips, cleans and repairs broked haldex Controllers and has advised how to take it apart while I have it off to fit the filter and if its corroded inside I'll send it off for repaid which he charges a very reasonable price for!!!
Anyone else had this issue?
Its not the oil - this was changed less than 2 k ago so was the pre charge pump. Pump is still working as i have tested it with VCDS. If I run a manual test of the haldex clutch I can hear it working and it also clears the error for a while then comes back after maybe 20 or 30 miles, if i just clear the error just using VCDS and not running a manual test it comes back immediately. Bit strange.
Also notice running VCDS logs on the haldex system the pump doesnt get about an 84% load which is probably due to a clogged filter Audi say doesn't need changing.
For anyone with the same issues i'll be hopefully sorting this out next thursday/friday when I have the parts and Im off work.
