Defender 90 TD5 1999---HELP PLEASE

[tidd]

hi all just joined need a bit of advice please,bought a defender 90 td5 1999 last week in Dundee Scotland drove it back to newcastle upon tyne no problems,broke down last Friday engine went in to limp mode doing 65mph on coast road,did some checks oil in ecu wiring cleaned it out looked in ecu no oil,engine management light on all time no acc pedal just limp mode,brakedown guy came out said I had seized wastegate so he took it off free-ed it up said I would have to get it put on diagnostics get engine management light off so off we go to team valley landrover said he would have a look first off he said needed new injector harness as oil leaking down it I said ok £200 for doing that and diagnostics they rang said engine light still on they checked the maf its ok throttle body that's ok might be wiring fault some where,just rang them said had few more checks to do on wiring but its looking like ecu buggered I took top off and checked it no oil that I could see,so their getting back to me tomm with a price for an ecu can I buy a second hand ecu from ebay and what do I have to do get it too work on mine any help would be much appreciated thank you all in advance.

make sure you get a 10p engine ECU as a 15p one will not work (10p up to 2001, 15p 2002 onwards.

 

[mikes lr]

first of there are 2 things that trigger mil lamp
1 throttle pedal
2 crankshaft position sensor
ecu is varnished and rarely die
if the injector harness is breaking down you would have missfire
tps goes to bcu then ecu via fusebox underbonnet
new ecu will plug in and go but best to programe injector codes into new ecu

 

[tidd]

Thanks guys ill ask him about the crank positon sensor tomm see if he checked that,will a discovery ecu work in defender as long as its a 10p one.

 

[Shifty1962]

Sounds like a throttle pedal problem as "limp" mode still allows some acceleration as does a stuck wastegate as would a dodgy injector loom.
Does it fire up OK and idle? If so the ECU is OK and just not getting throttle signal.
Ask them if they can see changing thottle signal on diagnostics. My Nanocom shows that so a pucker LR set up defo should.
Knackered crank position sensor will stop engine from running completely.

I'd not be too quick to buy a new ECU until the basics have been checked.

 

[tidd]

hi yes it fires up first turn key every time and idles fine, just nothing at acc pedal they said they checked throttle pedal sensor that's ok ill ask them about throttle signal. thanks

If it idles then there is nothing wrong with the injector harness as it would misfire and hunt all over the place otherwise. Also the crank position sensor must be OK for it to idle.
My guess is the throttle pedal wiring needs looking at if they say the throttle pedal potentiometer is OK.
If I unplug my throttle pedal my MIL (engine management) lamp lights up and obviously the engine just idles away happily.

 

[SteveT247]

Mine had a seized wastegate when I bought it. It might show overboost on diagnostics but you won't get a MIL from that (mine never did anyway).

 

[tidd]

thanks guys ill ring them in morning tell them check out throttle pedal wiring,the breakdown guy fixed the seized wastegate at least I no,no mill light off that ty.

 

[matchmetisse]

Tbh do they know what they are doing, sounds like you are doing the work they
Should know already

Tidds I would suggest you carefully consider your choice of garage. Not prepared to go into detail on an open forum, but will say I refuse to take mine there.?! There's quite few smaller garages around up here that are very good. If you insist on using a 4x4 specialist I would recommend Cheviot 4x4. Personally I find them expensive but good at their job.

Where you based.?!

i'm down the north east a fair bit, i'd be interested to know of good landy garages.

anywhere from shields to newcastle.. even sunderland would be good

 

[tidd]

hi I was on my way to cheviot 4x4 when I broke down to pick up some parts (door hinges new locks) I rang them told them id broken down on coast road he said cant help you no mechanics here, I rang round few garages see if they had diagnostic machine for defender 90 all said no landrover team valley don't seem too bothered whats wrong with my baby lol im going to get it tomm fixed or still broke any suggestions for good garages near Gateshead would be a great help thanks guys.

 

[BenNE]

There is a place in Washington, just past Makro on the same trading estate:

Spanner Monkeys

Marsha and Peter will be more than bothered about your Landy - Marsha even named mine for me when it went in for a bit of lecky work

Other than that, there is North East and Rover Services down in Sacriston. Never used them myself, but heard nothing but great reports from them, no website, but here is their numbers:

Mal : 07791725860
Trev : 07546123745

Hope you get the go go pedal sorted soon!

Ben

Edit: I have no affiliation with either of these companies.

 

[lanedriver]

If the repair shop cant find the fault, your Defender is in the wrong repair shop. Look up Durham 4x4 in Bowburn and speak with Graham, get your motor in to them; they will find and fix the problem for you; they are very reasonable and know their stuff.
I have been using their services for the past 4 years and would not go anywhere else...........

hi all quick update went to garage this afternoon saw manager asked him about all things you guys had thought it might be, he said hes checked them all every thing ok throttle pedal wiring fine no broken wires any where,he said was going to check all the wiring again if its ok the only thing left is duff ecu £600 plus vat dam but he might no someone with second hand one so just waiting on him ringing hopefully tomm ill find out lol.

 

[DJ Xan]

If it's ecu get the newer one part number starts NNN

 

[tidd]

hi all update,garage tried new ecu,still mill light on any one have any idea what it could be thanks.

 

[trax]

hope you aren't paying for all these new parts.. take it away from them as they seem clueless parts changers

 

[johnlad]

wild guess, throttle pedal
