TD5 engine types

Hi All

I have a yr 2000 TD5 in a 110 Defender, how do I find out if it's a 10p or 15p engine ? whats the differences between the two engines ?

do they run the same R380 gearbox ?

Same gear box.

Look at the engine number which is where the definitive answer as to what engine you have is shown. Otherwise as a quick and dirty method look at the fuel pressure regulator. If it has an external fuel spill pipe then it is likely a 15p but be careful as its not always the case. There were a few 10p engines fitted with the later heads.

Hi RJ

Does your TD5 have a decat down pipe... I have a 2001, and got ready to fit me shiny new decat pipe , only to find no cat!!:doh:

Anyone know when they started to fit Catalytic converters?

Also if the egr pipe is liquid cooled its the later engine if just a flexi pipe its the 10p motor.
Approx changeover was 2002.

Are the 10P and 15P engines interchangable? If so are the electronics compatible (ECU etc)?

I think I have a 15P in my early 2003 TD5 Discovery and the dealership has just bought a 10P engine to replace my broken engine.

It can be done but its not as easy as plug and play. Cant understand why you would want a 10p to replace the 15p though. The later engines had modified cylinder heads and metal head dowels as standard.

I replaced my fragged 10p with a 15p and used the same ECU. Needed a little bit of adjusted plumbing but other than that it went in quite easy.

As I say, the dealership I bought the vehicle from are replacing a failed engine with all they can find on Ebay at present (10P), hence my concern about the compatibility. 10P's also seem cheaper.

I doubt they even know there are different models. Thanks for the reply.

They are cheaper for good reason. early 10p engines were prone to cylinder head porosity or cracks in the internal fuel galleries resulting in elevated engine oil levels due to diesel in the oil.

Make sure the oil pump sprocket bolt is loctited as they have a habbit of coming loose.

Depends whats wrong with your original engine but keep all your old engine parts as they are worth money. For instance the injectors would be worth up to £100 each on eBay. The oil cooler (currently on 9 month backorder from LR) would be worth at least £150. The sump, FPR, oil pump all worth good money. The old cylinder head could be weighed in for £30 at the scrappy etc.

You would be surprised at what you got back. Just dont let them have it.

only the ECU's from newer or same engines will work on older ones not vice-versa.

I disagree. My original 1998 10p ECU works just fine with my later 15p engine. I just programmed the injector codes with Ratty's Nanocom but it ran fine without even doing that. After 20k miles its still running strong.

it means i'm wrong then ... just for my information, when you say "original" u mean not remapped, chipped or something ...cos if it is then IMO u can't name it original

my statement was based on the theory that if the ECU fails u can't put an older one instead.... i didnt try it myself but it was sustained by others

I'm only saying what I did and that it worked and continues to work.

Mine has a TD5Alive fuelling remap NOW but it did not when I replaced my engine. Just bolted the engine in and away it went. No changes to the ECU required.

My ECU is one of the early ones that had a non programmable soldered in main chip which Gary replaced with a socket so that he could fit a programmable one containing the remap.

I guess the old engine (cracked head - diesel in the sump) will be the property of the dealer as they are paying for the replacement engine.

If the engine is being replaced under warranty then I'd want like for like and not give a hoot what they did with the old engine - no way I'd settle for a second hand earlier engine sourced from a breakers. How do you know what state the salvaged engine is in? How many miles has it done. Was it left sitting in the rain for a few years before they bought it? Will the warranty be valid if things go wrong given that its a used engine? etc. etc. etc.

Also what about resale value? Anybody who knows their stuff will spot a 10p in a later car and start asking why. They'll also want money knocked off because of it.

All I'm saying is dont believe everything the dealer tells you. A quick search on ebay shows at least five 15p engines for sale with less than 50k miles for £2k or less at the current time.

I appreciate and agree with your comments but this is unfortunately not a large well funded dealership. I'm happy they are doing anything at all rather than going down the legal route. There are no winners in this one.

There are lots of old TD5's driving around with 10P engines so they cant be that bad! I have been fighting with them for a month now so just want to get my car back. And to make matters worse, on my last visit to check progress I found they had put a dent in it as well.

Why have you bought a decat pipe if there wasn't one on there originally anyway? Get rid of it. My 10p engine (current value probably) has done 230k miles and is probably only just run in ! BTW - no cat or centre silencer on mine.

10P doesnt have a cat, usually 15P does(unless it's an early Euro 2 one)

15p or 16p TD5- I fitted a supposedly 14K mile TD5 engine to my Disco II ( Auto) which seems is a really good engine. I want to re-map the engine ECU . How can I tell if it’s a 15p or 16p as there are many different ECU s and only programmable after c 2000.
I had the original non programmable ECU re –chipped about 10 years ago, but all this old chip seems to do is hold the gears lower and cause high revs.
Does anyone have a list of NNN codes to go with different engines? Many thanks Mark

1. Did you save the injector codes of the new engine into your ECU...cos if not it will run like sh*t

2. on the list i have the only two NNN ECU's for D2 auto's are:

NNN000130 - ELECTRONIC CONTROL UNIT ENGINE, AUTOMATIC TRANSMISSION, '(+)"EUROPE/J"'
NNN500030 - ELECTRONIC CONTROL UNIT ENGINE, AUTOMATIC TRANSMISSION, '(+)"EUROPE/J"'

Take a look at the engine number stamped on the engine block.
It will begin 10 or 15 or 16 etc.
