I've had a load of headaches with V6 Tdi Audi engines cost a fortune and gave up on last one in A6 , thankfully A4 is going ok ..... for now

I have Injectors that are 100% had them tested etc if you need any Paul

Good luck with your finish up and fire the old beast up

Cheers Neu - I might yet take you up on that, but all the signs are that it was cam/follower wear at the root of all evil - helped along by ~5yrs of Audi's own stupid longlife oil fiasco IMHO. Day job preventing progress today... I must try and tot up honestly how many hours I have invested so far - much of it is cleaning and such wrt rebuilding the heads.

I dread to imagine the labour bill from a main dealer for this. Well into four figures I expect. Someone asked me what I would charge for doing this job - it would need to be a tidy amount to make me even consider it... Have the scars - physical and mental to show for it.

Grabbed a few hours dodging rain, darkness and the day job. All the belts are on. Cold cranked and no nasty noises... oil pressure seen building up in the heads with covers off. Water pipes on and that stupid vacuum pump refitted as well. Seeing as I removed it ~2 weeks ago I had forgotten that it doesn't align with the slots used for camshaft alignment - it aligns in the other slot. Fought with the damn thing for ~20mins before going for lunch where I suddenly remembered the cam as two slots... D'oh

Just got the fuel system to bleed, the air pipes to refit and electrical plugs to reconnect and it should be rumbling tomorrow. Then I can fill it with water, put the covers and vicious fan back on before a bit of bumper juggling.

As of 4pm today - it's alive. I have never been as happy to hear a diesel engine :-)

Beer tonight - bumper & undertray tomorrow.

Victory is mine ~ 800 quid, 20 grey hairs and countless lacerations on hands and wrists later !

Fair play to you, those skinned knuckes must have saved you 2 grand! What are you going to buy for the S2 with it? :mischeif:

Cannot spend what I dinny have. Lol

Congrats, good to see a happy end to a long and arduous journey. I have to admit you've put me off these engines somewhat.

Well Done that man !

theyre a pain in the butt for sure, i've spent a load on v6 TDi

Hows it running now?

[S2central.net]

Its running 100% - definitely quieter and pulling nice and strong. Starts on the button with glowplugs that actually work too.

I think its taking slightly longer to warm up cos of EGR deletion - but I'd rather have that versus breathing all that muck back in. The ECU doesn't complain about EGR deletion either - even if it is sucking more air thru the MAF on idle & cruise than what it would do otherwise. Wonder if it using a touch more fuel as a result but the mysteries of diesel management don't really interest me much.

Well done Paul, brilliant result

[diesel des]

Should use no more fuel, as there is more excess air to burn it efficiently. Also turbo spool should be better, but nox emissions worse. Who cares another nox though. You need to get the ecu tweeked on that. Really helps with power and even fuel econ...

Paul, quick question,

alternator has just gone on my a4 2.5tdi, is it possible to remove and replace it without removing the front end?
Ive not even looked at it yet... though id ask someone whos spent some time in there..

[S2central.net]

Clearance is tight down there. I would expect that bumper needs to go into service position to get access to bolts for alternator brackets. Don't take my word alone though - have a good recce first.

Cheers and good luck

Paul
