We kept the engine running doing this for roughly 20 seconds, and when I stopped the spray the engine continued by itself or more correctly with diesel as normal. I did this several times, to no avail, engine did not fire up, so I got my "assist tech" and he turned the key, while I used a starter gas. Pump starts for 30 seconds, and repeat ON/OFF. I used Vag Com to activate go to 1 Engine then 4 Basic settings (if no drop down, enter 035 in group and go) and activate.

The manual stated that one need to purge the diesel system by means of the lift pump, no less than 3 times.

I specially liked the first one, in conjunction to use of manual. There is a few good links I want to share, and they are as hyperlink below.

Also did a timing belt replacement after finished installing head. I followed the instruction from Audi manual, regarding reassembling cylinder head and fitting to car. just select manufacturer og continue, very easy to use.įinally, after a few weeks off-shore and waiting for parts, I got home and my Father-in-law´s Audi A6 2.0tdi with BRE engine is again working.
#Audi a6 2006 key free
I found 3 or 4 roller rocker arms on inlet side with loose centerline pin on roller bearings, this meaning that the roller bearings would eventually be able to come free from the roller rocker arm itself, leaving needles, center-pin (inner bearing race) and bearing outer race floating in top witch could again cause havoc.Īll the best to You folks, and heres a link for car parts catalogue, if some people does not have it. Please note, as to me it now seems like this might be an issue with these motors. I would like to post some photos, but do not know hot to do so, but maybe this dropbox works? When top is done, Ill take down the oilsump and check/remove debris from there as well, hopefully it shall have 2 halves of roller outer race, and a good few of the needles from roller bearings New timing belt set with water pump is also in order. Still consider buying new complete set of rocker arms for valves or just replace the 3 defect ones in exhaust side, and a few "defect" ones on inlet side. The turbo and its bearing is also in perfect condition, furthermore the filter should have picked these up, so the needles can or should be able to get into intake line via oilstream to turbo, nor elsewhere, what am I missing?Īnyway, new stretch (head) bolts for cylinder top and PD rocker arm bolts in order, same is new seals. No physical line of entry from inside top head and into combustion chamber as long as valve stems, valve guides and their seals is present, and without damage (as they are), these needles in 1mm in diameter and 5mm long.

What really bugs me is the many marks in pistons 3 and 4 plus in cyl head 3 and 4, the marks corresponds to the needles in roller bearings in rocker arms, but how the hell did they get into the combustion chamber. I have checked all valves, they are good, but I did refurbished their seat and seal face, they are now good to go, valve stem OK as well as all valve guide and guide seals in place, no damage in them. Just an update, and see hyperlink for some of the parts just below.ģ of the exhaust valve roller rocker arms is FUBAR, the thick/wide ones, rollers broke in half with all needle pins (apart from the 10 I found in head) most likely they are down in oil sump. I wish you well with your repair and tear down. for PD, it might be worth a look to change all this stuff while apart. There are kits out there to sell the cam and all lifters etc. Line the valves up on the bench to see if they hit a piston buy observing the height is uniform.Ĭheck tops of pistons for index hit points from valves and inspect the seats of the valves in head and decks.īe sure to inspect the cam bearing journals and remediate carbon in all intake ports while off and that cam bearing bridges have not cracked. Remove the head and take all valves out to verify for broken springs. Remove cam and see if the cylinders will hold compressed regulated air, further using the glow plug holes and manually fixing the crank to a safe position of BDC.

I would recommend if the belt broke that you verify the taper fit virtual pulley key-way on camshaft hub and crank gear key-way for proper inspection of centerline. The lifters and camshaft seem to suffer extreme wear causing holes within the lifter face & in addition to cam lobe damage. These engine's are most known for as you aforementioned lubrication issues and also why they require a special oil specification. The BRE is PD type TDI which mechanically fires the injectors by the camshaft and also controlled deviation by the ECU.
