I have the 1.9Tdi with115hp Engine (AUY) and I may need to spend money on it due to poss head gone. Could anyone tell me if the 1.9/2.0 engines with 130/150/170 bhp from the VW/Audi range will fit easily or are all electronics and looms different? :1zhelp: Please.
Pretty much bolt in in most respects BUT the injectors on the 130/150 are different to the 115 and I don’t think they would work correctly. If you only fitted the block/head of a 1350/150 in a 115, you would still only have 115PS, you would not have the power of the new engine.
Thanks for that Crasher, I am getting the head off it this week and hope it's just a gasket job. I have been told it starts getting expensive if head warped/cracked so wanted to find out if it would be easier to drop another lump in.Quote:

If you have a head gasket leak, don’t expect to be able to see any visible signs on the block, head or gasket, they leak so subtlety I have never yet seen the actual leak.
K Thanks for that Crasher, will let you know how I get on when I get the head off, don't want to throw too many £'s after this but would like to try and sort it as I've had the car since new and was gonna run it till it was broke. It will be a poor show if it's broke after 100k and 9yrs.........Quote:

I really hope this is not the case as it will surely be cheaper to source another lump to put in? Crasher does the head usually need skimming or can you just get away with just fitting a new gasket? I expect though it will be wise to get it checked and pressure tested?
Seems this is not an uncommon problem with the 1.9pd engine.
depending on whether you're at the mercy of the garage, or intend to DIY (I'd advise against this unless you know what you're doing).Quote:

I sourced a head for ~£350, with a new cam and followers coming in at around £150 (new lifters, used cam), injectors were coming in at around £100 cost (with trade discount iirc).
with other parts such as seals, belt and bolt kits, the total job came in at just short of £1000, that was with DIY.
I would seriously consider whether the value of the car allows you to consider a re-head or engine before you proceed bud.
If the injectors require the special VAG slide hammer tool to remove them, it can mean that the injector bores are damaged (see pic) as a result of the injectors moving around which itself is the result of a poor design. A head from AMC is about £400 and four Bosch injectors can be bought for just under £1K but often the injectors are OK as they are steel and just show rubbing marks on their sides, it is the head that suffers. The head, according to VW, should not be skimmed or reworked in any way but I have had full VW exchange PD heads (rather scary at over £2.5K) and these have quite obviously been refaced by VW so I am not sure why they say that but yes, I think it must be refaced to make sure it is true and flat and to do this the valves, injectors and glow plugs must be removed, never ever refit old glow plugs, a broken £10 glow plug will seriously ruin your day. You could fit another engine but who is to say it is not in the same state or worse? Of course if the valves are removed then you should fit new lifters (about £10 each) and PD cams are prone to wear but I am very suspicious of pattern PD cams, I have seen some fail at an alarming rate.

Thanks for your help, all the above is good advice and usefull. I am gonna bite the bullet and get the head off and see where we go from there. I have pretty good mechanical knowledge having spent a couple of years spannering albeit a few years ago on older cars but also have a mate who is helping who is currently a fitter/technician so will let you know what we find.Quote:
